Standard Practice for Tests to Evaluate the Chemical Resistance of Geomembranes to Liquids

Standard Practice for Tests to Evaluate the Chemical Resistance of Geomembranes to Liquids

SIGNIFICANCE AND USE
5.1 This practice is intended to provide a list of standard procedures for test programs investigating the chemical resistance of a geomembrane with a liquid waste, leachate, or chemical. This practice should be used in the absence of other specifications required for the particular situation being addressed.  
5.2 Chemical resistance, as used in this practice, is not a quantifiable term. This practice is intended to provide a basis of standardization for those wishing to compare or investigate the chemical resistance of a geomembrane. It should be recognized that chemical resistance is a user judgment evaluation and that this practice does not offer procedures for interpreting the results obtained from test procedures contained in this practice. As a practice, this does not produce a test result.
Note 1: This practice is for the chemical resistance assessment of geomembranes and is written in parallel to similar standard practices for geotextiles, geonets, geogrids, geopipes, and geosynthetic clay liners. Each standard is to be considered individually for the geosynthetic under investigation and collectively for all geosynthetics exposed to the potentially harsh chemical environment under consideration.
SCOPE
1.1 This practice covers procedures for the testing of geomembranes for chemical resistance with liquid wastes, prepared chemical solutions, and leachates derived from solid wastes.  
1.2 This practice covers procedures for testing semi-crystalline, amorphous, elastomeric, and fabric-reinforced geomembranes.  
1.3 This practice is intended to be used in conjunction with Practice D5322 or D5496, or both. The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geomembrane samples.  
1.4 Evaluation and interpretation of test data are beyond the scope of this practice.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D6637/D6637M-15(2023)(Test Method)
Standard Test Method for Determining Tensile Properties of Geogrids by the Single or Multi-Rib Tensile Method

SIGNIFICANCE AND USE
5.1 The determination of the tensile force-elongation values of geogrids provides index property values. This test method shall be used for quality control and acceptance testing of commercial shipments of geogrids.  
5.2 In cases of dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing began. If a bias is found, either its cause must be found and corrected or the purchaser and supplier must agree to interpret future test results in light of the known bias.  
5.3 All geogrids can be tested by any of these methods. Some modification of techniques may be necessary for a given geogrid depending upon its physical makeup. Special adaptations may be necessary with strong geogrids, multiple layered geogrids, or geogrids that tend to slip in the clamps or those which tend to be damaged by the clamps.
SCOPE
1.1 This test method covers the determination of the tensile strength properties of geogrids by subjecting strips of varying width to tensile loading.  
1.2 Three alternative procedures are provided to determine the tensile strength, as follows:  
1.2.1 Method A—Testing a single geogrid rib in tension (N or lbf).  
1.2.2 Method B—Testing multiple geogrid ribs in tension (kN/m or lbf/ft).  
1.2.3 Method C—Testing multiple layers of multiple geogrid ribs in tension (kN/m or lbf/ft).  
1.3 This test method is intended for quality control and conformance testing of geogrids.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5884/D5884M-23(Test Method)
Standard Test Method for Determining Tearing Strength of Internally Reinforced Geomembranes

SIGNIFICANCE AND USE
5.1 Since tear resistance may be affected to a large degree by mechanical fibering of the membrane under stress, as well as by stress distribution, strain rate, and size of specimen, the results obtained in a tear resistance test can only be regarded as a measure of the resistance under the conditions of that particular test and not necessarily as having any direct relation to service value. This test method measures the force required to tear a reinforced geomembrane along a reasonably defined course such as that the tear propagates across the width of the specimen. The values may vary between types of reinforcement used within a geomembrane.  
5.2 The tongue tear method is useful for estimating the relative tear resistance of different reinforcing textiles or different directions in the same reinforcing textiles.  
5.3 Disputes—In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical difference between their laboratories.
SCOPE
1.1 This test method covers a uniform procedure for determining the tear strength of flexible geomembranes internally reinforced with a textile, using the tongue tear method.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Measuring Asperity Height of Textured Geomembranes

SIGNIFICANCE AND USE
5.1 The asperity height is an index property used to quantify one of the physical attributes related to the surface roughness of textured geomembranes.  
5.2 This test method is applicable to all currently available textured geomembranes that are deployed as manufactured geomembrane sheets.
SCOPE
1.1 This test method covers a procedure to measure the asperity height of textured geomembranes.  
1.2 This test method does not provide for measurement of the spacing between the asperities nor of the complete profile of the textured surface.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

Standard Test Method for Measurement of Index Flux Through Saturated Geosynthetic Clay Liner Specimens Using a Flexible Wall Permeameter

SIGNIFICANCE AND USE
5.1 This test method yields the flux of water through a saturated GCL specimen that is consolidated, hydrated, and permeated under a prescribed set of conditions.  
5.2 This test method can be performed to determine if the flux of a GCL specimen exceeds the maximum value stated by the manufacturer.  
5.3 This test method can be used to determine the variation in flux within a sample of GCL by testing a number of different specimens.  
5.4 This test method does not provide a flux value to be used directly in design calculations.
Note 1: Flux for in-service conditions depends on a number of factors, including confining pressure, type of hydration fluid, degree of hydration, degree of saturation, type of permeating fluid, and hydraulic gradient. Correlation between flux values obtained with this test method and flux through GCLs subjected to in-service conditions has not been fully investigated.  
5.5 This test method does not provide a value of hydraulic conductivity. Although hydraulic conductivity can be determined in a manner similar to the method described in this test method, the thickness of the specimen is needed to calculate hydraulic conductivity. This test method does not include procedures for measuring the thickness of the GCL nor of the clay component within the GCL. Refer to Appendix X2 for calculation of hydraulic conductivity.  
5.6 The apparatus used in this test method is commonly used to determine the hydraulic conductivity of soil specimens. However, flux values measured in this test are typically much lower than those commonly measured for most natural soils. It is essential that the leakage rate of the apparatus used in this test be less than 10 % of the flux.
SCOPE
1.1 This test method covers an index test that covers laboratory measurement of flux through saturated geosynthetic clay liner (GCL) specimens using a flexible wall permeameter.  
1.2 This test method is applicable to GCL products having geotextile backing(s). It is not applicable to GCL products with geomembrane backing(s), geofilm backing(s), or polymer coating backing(s).  
1.3 This test method provides a measurement of flux under a prescribed set of conditions that can be used for manufacturing quality control. The test method can also be used to check conformance. The flux value determined using this test method is not considered to be representative of the in-service flux of GCLs.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5820-95(2023)(Practice)
Standard Practice for Pressurized Air Channel Evaluation of Dual-Seamed Geomembranes

SIGNIFICANCE AND USE
5.1 The increased use of geomembranes as barrier materials to restrict liquid or gas movement, and the common use of dual-track seams in joining these sheets, has created a need for a standard nondestructive test by which the quality of the seams can be assessed for continuity and watertightness. The test is not intended to provide any indication of the physical strength of the seam.  
5.2 This practice recommends an air pressure test within the channel created between dual-seamed tracks whereby the presence of unbonded sections or channels, voids, nonhomogenities, discontinuities, foreign objects, and the like, in the seamed region can be identified.  
5.3 This technique is intended for use on seams between geomembrane sheets formulated from the appropriate polymers and compounding ingredients to form a plastic or elastomer sheet material that meets all specified requirements for the end use of the product.
SCOPE
1.1 This practice covers a nondestructive evaluation of the continuity of parallel geomembrane seams separated by an unwelded air channel. The unwelded air channel between the two distinct seamed regions is sealed and inflated with air to a predetermined pressure. Long lengths of seam can be evaluated by this practice more quickly than by other common nondestructive tests.  
1.2 This practice should not be used as a substitute for destructive testing. Used in conjunction with destructive testing, this method can provide additional information regarding the seams undergoing testing.  
1.3 This practice supercedes Practice D4437/D4437M for geomembrane seams that include an air channel. Practice D4437/D4437M may continue to be used for other types of seams. The user is referred to the referenced standards or to EPA/530/SW-91/051 for additional information regarding geomembrane seaming techniques and construction quality assurance.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Ultrasonic Testing of Geomembranes

SIGNIFICANCE AND USE
5.1 This practice covers test arrangements, measurement techniques, sampling methods, and calculations to be used for nondestructive evaluation of geomembranes using ultrasonic testing.  
5.2 Wave velocity may be established for particular geomembranes (for specific polymer type, specific formulation, specific density). Relationships may be established between velocity and both density and tensile properties of geomembranes. An example of the use of ultrasound for determining density of polyethylene is presented in Test Method D4883. Velocity measurements may be used to determine thickness of geomembranes (1, 2).4 Travel time and amplitude of transmitted waves may be used to assess the condition of geomembranes and to identify defects in geomembranes including surface defects (for example, scratches, cuts), inner defects (for example, discontinuities within geomembranes), and defects that penetrate the entire thickness of geomembranes (for example, pinholes) (3, 4). Bonding between geomembrane sheets can be evaluated using travel time, velocity, or impedance measurements for seam assessment (5-10). Examples of the use of ultrasonic testing for determining the integrity of field and factory seams through travel time and velocity measurements (resulting in thickness measurements) are presented in Practices D4437 and D4545, respectively. An ultrasonic testing device is routinely used for evaluating seams in prefabricated bituminous geomembranes in the field (11). Integrity of geomembranes may be monitored in time using ultrasonic measurements.
Note 1: Differences may exist between ultrasonic measurements and measurements made using other methods due to differences in test conditions such as pressure applied and probe dimensions. An example is ultrasonic and mechanical thickness measurements.  
5.3 The method is applicable to testing both in the laboratory and in the field for parent material and seams. The test durations are very short as wave transmission through ...
SCOPE
1.1 This practice provides a summary of equipment and procedures for ultrasonic testing of geomembranes using the pulse echo method.  
1.2 Ultrasonic wave propagation in solid materials is correlated to physical and mechanical properties and condition of the materials. In ultrasonic testing, two wave propagation characteristics are commonly determined: velocity (based on wave travel time measurements) and attenuation (based on wave amplitude measurements). Velocity of wave propagation is used to determine thickness, density, and elastic properties of materials. Attenuation of waves in solid materials is used to determine microstructural properties of the materials. In addition, frequency characteristics of waves are analyzed to investigate the properties of a test material. Travel time, amplitude, and frequency distribution measurements are used to assess the condition of materials to identify damage and defects in solid materials. Ultrasonic measurements are used to determine the nature of materials/media in contact with a test specimen as well. Measurements are conducted in the time-domain (time versus amplitude) or frequency-domain (frequency versus amplitude).  
1.3 Measurements of one or more ultrasonic wave transmission characteristics are made based on the requirements of the specific testing program.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development ...

Standard Test Method for Measuring the Filtration Compatibility of Soil-Geotextile Systems

SIGNIFICANCE AND USE
5.1 This test method is recommended for the evaluation of the performance of water-saturated soil-geotextile systems under unidirectional flow conditions. The results obtained may be used as an indication of the compatibility of the soil-geotextile system with respect to both particle retention and flow capacity.  
5.2 This test method is intended to evaluate the performance of specific on-site soils and geotextiles at the design stage of a project, or to provide qualitative data that may help identify causes of failure (for example, clogging, particle loss). It is not appropriate for acceptance testing of geotextiles. It is also improper to utilize the results from this test for job specifications or manufacturers' certifications.  
5.3 This test method is intended for site-specific investigation therefore is not an index property of the geotextile, and thus is not intended to be requested of the manufacturer or supplier of the geotextile.
SCOPE
1.1 This test method covers performance tests applicable for determining the compatibility of geotextiles with various types of water-saturated soils under unidirectional flow conditions.  
1.2 Two evaluation methods may be used to investigate soil-geotextile filtration behavior, depending on the soil type:  
1.2.1 For soils with a plasticity index lower than 5, the systems compatibility shall be evaluated per this standard.  
1.2.2 For soils with a plasticity index of 5 or more, it is recommended to use Test Method D5567 (‘HCR,’ Hydraulic Conductivity Ratio) instead of this test method.  
1.2.3 If the plasticity index of the soil is close to 5, the involved parties shall agree on the selection of the appropriate method prior to conducting the test. This task may require comparison of the permeability of the soil-geotextile system to the detection limits of the HCR and Gradient Ratio Test (GRT) test apparatus being used.  
1.3 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determining Integrity of Seams Produced Using Thermo-Fusion Methods for Reinforced Geomembranes by the Strip Tensile Method

SIGNIFICANCE AND USE
4.1 The use of reinforced geomembranes as barrier materials has created a need for a standard test method to evaluate the quality of seams produced by thermo-fusion methods. This test method is used for quality control purposes and is intended to provide quality control and quality assurance personnel with data to evaluate seam quality.  
4.2 This standard arose from the need for a destructive test method for evaluating seams of reinforced geomembranes. Standards written for destructive testing of nonreinforced geomembranes do not include all break codes (Fig. 1) applicable to reinforced geomembranes.
FIG. 1 Break Codes for Dual Hot Wedge and Hot Air Seams of Reinforced Geomembranes Tested for Seam Strength in Shear and Peel Modes  
4.3 When reinforcement occurs in directions other than machine and cross-machine, scrim are cut at specimen edges, generally lowering results. To partially compensate for this, testing can be performed according to Test Method D7749 or the 2 in. wide strip specimen specified in this method can be utilized. Testing of 1 in. and 2 in. specimens is Method A and Method B, respectively.  
4.4 The shear test outlined in this method correlates to strength of parent material measured according to Test Method D7003/D7003M only if reinforcement is parallel to TD. For other materials, seam strength and parent material strength can be compared through Test Methods D7749 and D7004/D7004M. Values obtained with the strip methods shall not be compared to values obtained with grab methods.
SCOPE
1.1 This test method describes destructive quality control tests used to determine the integrity of thermo-fusion seams made with reinforced geomembranes. Test procedures are described for seam tests for peel and shear properties using strip specimens.  
1.2 The types of thermal field and factory seaming techniques used to construct geomembrane seams include the following:  
1.2.1 Hot Air—This technique introduces high-temperature air between two geomembrane surfaces to facilitate melting. Pressure is applied to the top or bottom geomembrane, forcing together the two surfaces to form a continuous bond.  
1.2.2 Hot Wedge—This technique melts the two geomembrane surfaces to be seamed by running a hot metal wedge between them. Pressure is applied to the top and bottom geomembrane to form a continuous bond. Some seams of this kind are made with dual tracks separated by a non-bonded gap. These seams are sometimes referred to as dual hot wedge seams or double-track seams.  
1.2.3 Extrusion—This technique encompasses extruding molten resin between two geomembranes or at the edge of two overlapped geomembranes to effect a continuous bond.  
1.2.4 Radio Frequency (RF) or Dielectric—High-frequency dielectric equipment is used to generate heat and pressure to form an overlap seam in factory fabrication.  
1.2.5 Impulse—Clamping bars heated by wires or a ribbon melt the sheets clamped between them. A cooling period while still clamped allows the polymer to solidify before being released.  
1.3 The types of materials covered by this test method include, but are not limited to, reinforced geomembranes made from the following polymers:  
1.3.1 Very low-density polyethylene (VLDPE).  
1.3.2 Linear low-density polyethylene (LLDPE).  
1.3.3 Flexible polypropylene (fPP).  
1.3.4 Polyvinyl chloride (PVC).  
1.3.5 Chlorosulfonated polyethylene (CSPE).  
1.3.6 Ethylene interpolymer alloy (EIA).  
1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish ap...

Standard Test Method for Accelerated Tensile Creep and Creep-Rupture of Geosynthetic Materials Based on Time-Temperature Superposition Using the Stepped Isothermal Method

SIGNIFICANCE AND USE
5.1 Use of the Stepped Isothermal Method decreases the time required for creep to occur and the obtaining of the associated data.  
5.2 The statements set forth in 1.6 are very important in the context of significance and use, as well as scope of the standard.  
5.3 Creep test data are used to calculate the creep modulus of materials as a function of time. These data are then used to predict the long-term creep deformation expected of geosynthetics used in reinforcement applications.
Note 1: Currently, SIM testing has focused mainly on woven and knitted geogrids and woven geotextiles made from polyester, aramid, polyaramid, poly-vinyl alcohol (PVA), and polypropylene yarns and narrow strips. Additional correlation studies on other materials are needed.  
5.4 Creep-rupture test data are used to develop a regression line relating creep stress to rupture time. These results predict the long-term rupture strength expected for geosynthetics in reinforcement applications.  
5.5 Tensile testing is used to establish the ultimate tensile strength (TULT) of a material and to determine elastic stress, strain, and variations thereof for SIM tests.  
5.6 Ramp and Hold (R+H) testing is done to establish the range of creep strains experienced in the brief period of very rapid response following the peak of the load ramp.
SCOPE
1.1 This test method covers accelerated testing for tensile creep, and tensile creep-rupture properties using the Stepped Isothermal Method (SIM).  
1.2 The test method is focused on geosynthetic reinforcement materials such as yarns, ribs of geogrids, or narrow geotextile specimens.  
1.3 The SIM tests are laterally unconfined tests based on time-temperature superposition procedures.  
1.4 Tensile tests are to be completed before SIM tests and the results are used to determine the stress levels for subsequent SIM tests defined in terms of the percentage of Ultimate Tensile Strength (TULT). Additionally, the tensile test can be designed to provide estimates of the initial elastic strain distributions appropriate for the SIM results.  
1.5 Ramp and Hold (R+H) tests may be completed in conjunction with SIM tests. They are designed to provide additional estimates of the initial elastic and initial rapid creep strain levels appropriate for the SIM results.  
1.6 This method can be used to establish the sustained load creep and creep-rupture characteristics of a geosynthetic. Results of this method are to be used to augment results of Test Method D5262 and may not be used as the sole basis for determination of long-term creep and creep-rupture behavior of geosynthetic material.  
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Selection of Test Methods for Ethylene Propylene Diene Terpolymer (EPDM) Geomembranes

SIGNIFICANCE AND USE
4.1 This standard provides guidance to obtain data that is the most representative of the material’s characteristics and performance. To properly evaluate EPDM, tests should be performed in accordance with specific test methods and procedures.
SCOPE
1.1 This guide covers and provides recommendations for the selection of appropriate test methods for Ethylene Propylene Diene Terpolymer (EPDM) geomembranes used in geotechnical and geoenvironmental applications.  
1.2 This guide includes test methods for three different types of EPDM geomembranes including: scrim-reinforced membranes, composite membranes, and smooth, nonreinforced membranes.  
1.3 The test methods are divided into three categories including manufacturing quality control, optional performance tests, and seam testing.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
