SIGNIFICANCE AND USE
5.1 This test method evaluates RECPs and their means of installation to:
5.1.1 Reduce soil loss and sediment concentrations in stormwater runoff under conditions of varying channel conditions and soil type;
5.1.2 Function within a composite system acting as vegetative reinforcement; and
5.1.3 Improve water quality exiting the area disturbed by earthwork activity by minimizing mobilization of in-situ particles within the streambed.
5.2 This test method models and examines conditions typically found on construction sites involving earthwork activities, including: highways and roads; airports; residential, commercial and industrial developments; pipelines, mines, and landfills; golf courses; etc.
5.3 This test method is a performance test, but can be used for quality control to determine product conformance to project specifications. Caution is advised since information regarding laboratory specific precision is incomplete. For project specific conformance, unique project-specific conditions should be taken into consideration.
SCOPE
1.1 This test method covers the guidelines, requirements and procedures for evaluating the ability of Rolled Erosion Control Products (RECPs) to protect earthen channels from stormwater-induced erosion. Critical elements of this protection are the ability of the RECP to:
1.1.1 Neutralize and absorb the hydraulic force of stormwater, thereby reducing soil particle loosening through “scour” mechanisms;
1.1.2 Slow runoff and encourage sedimentation, thereby reducing soil particle transport downstream;
1.1.3 Absorb shear forces of overland flow;
1.1.4 Trap soil particles beneath; and
1.1.5 Promote the establishment of vegetation.
1.2 This test method utilizes full-scale testing procedures, rather than reduced-scale (bench-scale) simulation, and is patterned after conditions typically found on construction sites prior to and after revegetation work. Further, procedures for evaluation of baseline conditions are provided. Thus, test preparation, test execution, data collection, data analysis and reporting procedures herein are intended to be suitable for testing of bare soil, unvegetated RECP, vegetated soil and vegetated RECP conditions.
1.3 This test method provides a comparative evaluation of an unvegetated RECP to baseline bare soil conditions and a vegetated RECP to a baseline, vegetated condition under controlled and documented conditions.
1.4 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are provided for information purposes only.
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. Also, the user must comply with prevalent regulatory codes, such as OSHA (Occupational Health and Safety Administration) guidelines, while using the test method.
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.

SIGNIFICANCE AND USE
5.1 Rock for erosion control is composed of pieces of natural rock that are placed on construction projects, shorelines, streambeds, bridge abutments, pilings, and other structures to minimize the effects of erosion. The ability of rock to withstand deterioration from weathering affects both the effectiveness of the project and its cost. The specific gravity and absorption of rock provide useful information that can be used in evaluating the durability of the rock as well as its resistance to movement by water.
5.2 The absorption of water into rock may affect its durability under freezing conditions and salt crystallization conditions. In addition, the absorption test has been used as an index test in determining whether additional tests are needed to evaluate the durability of a rock.
5.3 Test specimens equal in size to the proposed design size would provide the best correlations between laboratory tests and actual field performance, however this is usually neither practical nor economically feasible.
5.4 The results of these tests are not to be used as the sole basis for determination of rock durability, and shall be used in conjunction with the results of other tests.
5.5 These test methods have been used to evaluate different types of rocks. There have been rare occasions when test results have provided data that have not agreed with the durability of rock under actual field conditions. For example, some rocks with low absorption values have fragmented in actual usage and some with high absorption values have proven to be durable.
Note 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies which meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure r...
SCOPE
1.1 This test method covers the determination of specific gravity and absorption of rock for erosion control. The specific gravity may be expressed as bulk specific gravity or apparent specific gravity. Bulk specific gravity and absorption are based on a 24 ± 4-h soaking time for the rock specimens tested. This test is appropriate for breakwater stone, armor stone, riprap, and gabion sized rock materials, or similar.
1.2 The use of reclaimed concrete and other materials is beyond the scope of this test method.
1.3 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.
1.3.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculations are involved.
1.3.2 It is common practice in the engineering/construction profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf). This practice implicitly combines two separate systems of units; the absolute and the gravitational systems. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated, this standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass. However, the use of balances and scales recording pounds of mass (lbm) shall not be regarded as nonconformance with this standard.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.

SIGNIFICANCE AND USE
5.1 The ash content of the degradable ECP may consist of various residues from chemicals used in its manufacture, metallic matter from piping and machinery, mineral matter in the ECP fibers from which the degradable ECP was made, and filling, coating, pigmenting or other added materials. The amount and composition of the ash is a function of the presence or absence of any of these materials or others singly or in combination. No specific qualitative meaning is attached to the term “ash” as used in this test method.
5.2 In most cases, the ash content of ECPs will contain inorganic residues from the ECP fibers, inorganic residues from any added chemicals, and loading or filling materials deliberately added.
5.3 For ECP fibers containing cellulose and clays, or materials having variable chemical composition, variable thermal decomposition behavior, or both, the ash level may necessitate significant confirmation regarding the materials added.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors
SCOPE
1.1 This test method covers the determination of the ash and organic matter contents of degradable Erosion Control Products (ECPs) by ignition at 900 ± 25°C. This test method is primarily used to determine the ash and organic matter contents of degradable erosion control products (ECPs) to satisfy specifications set forth by various agencies.
1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.
1.3.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering data.
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.

SIGNIFICANCE AND USE
5.1 This test method utilizes large-scale testing equipment and procedures established at a variety of testing laboratories over the last 30 years.
5.2 This method is useful in evaluating ECPs and their installation to reduce soil loss and sediment concentrations when exposed to defined rainfall conditions and improving water quality exiting the area disturbed by earthwork activity by reducing suspended solids and turbidity.
5.3 This test method is a performance test, but can also be used for acceptance testing to determine product conformance to project specifications. For project-specific conformance, unique project-specific conditions should be considered. Caution is advised since information regarding laboratory specific precision is incomplete at this time, and differences in soil and other environmental and geotechnical conditions may affect ECP performance.
5.4 This standard can also be used as a comparative tool for evaluating the erosion control characteristics of different ECPs and can also be used to gain agency approvals.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
SCOPE
1.1 This test method is used to evaluate the ability of erosion control products (ECP) to protect slopes from rainfall-induced erosion using an adjustable tilting bed slope. The standard slopes range from 2:1 to 4:1 (H:V) having a target rainfall intensity of 3.5 in./h [90 mm/h].
1.2 There are three main elements the ECPs must have the ability to perform: 1. Absorb the impact force of raindrops, thereby reducing soil particle loosening and detachment through “splash” mechanisms; 2. Slow runoff and encourage infiltration, thereby reducing soil particle displacement and transport through “overland flow” mechanisms; and 3. Trap soil particles beneath the ECP. When comparing data from different ECPs under consideration, it is important to keep the test conditions the same for the ECPs being evaluated, for example, the rainfall intensity rate and the slope.
1.3 The results of this test method can be used to evaluate performance and acceptability, and can be used to compare the effectiveness of different ECPs. This method provides a comparative evaluation of an ECP to baseline bare soil conditions under controlled and documented conditions. This test method can provide information about a product that is under consideration for a specific application where no performance information currently exists.
1.4 This test method covers the use of three different soil types, ECP installation: sprayed, rolled, or dry applied, and a runoff collection procedure. This test is typically performed indoors, but may be performed outside as long as certain requirements are met. Partially enclosed facilities are acceptable providing the environmental conditions are met.
1.5 Units—The values stated in either inch-pound units or SI 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. Reporting of test results in units other than inch-pound shall not be regarded as nonconformance with this standard.

SIGNIFICANCE AND USE
5.1 The meaning of the test is related to the manufacturing and end use of the material, to determine characteristics of products.
5.2 A manufacturer of raw psyllium will base the grade of psyllium produced on multiple properties of which swell volume is one.
5.3 Erosion control contractors and those writing erosion control specifications will use this test method to evaluate the grade of psyllium being used as a hydraulically applied erosion control product. The swell volume will help determine the application rate of psyllium needed to meet the erosion control performance criteria.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
SCOPE
1.1 The purpose of this quantitative test method is to provide a means of determining the swell volume plantago insularis (Ovata, Psyllium).
1.2 The volume of swell reflects the amount of hydrophilic mucilloid present in psyllium. The higher the grade of psyllium the higher the swell volume, thus a greater percent of mucilloid present. For the erosion control industry, the higher the swell volume of the psyllium the greater it’s bonding strength and relative performance.
1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.
1.4.1 For purposes of comparing, a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits.
1.4.2 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.
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.

SIGNIFICANCE AND USE
5.1 Hydraulically operated stationary piston samplers are used to gather soil samples for laboratory or field testing and analysis for geologic investigations, soil chemical composition studies, and water quality investigations. The sampler is sometimes used when attempts to recover unstable soils with thin-walled tubes, Practice D1587/D1587M, are unsuccessful. Examples of a few types of investigations in which hydraulic stationary piston samplers may be used include building site foundation studies containing soft sediments, highway and dam foundation investigations where softer soil formation need evaluation, wetland crossings utilizing floating structures, and hazardous waste site investigations. Hydraulically operated stationary piston samplers provide specimens necessary to determine the physical and chemical composition of soils and, in certain circumstances, contained pore fluids (see Guide D6169/D6169M).
5.2 Hydraulically operated stationary piston samplers can provide relatively intact soil samples of soft or loose formation materials for testing to determine accurate information on the physical characteristics of that soil. Samples of soft formation materials can be tested to determine numerous soil characteristics such as; soil stratigraphy, particle size, water content, permeability, shear strength, compressibility, and so forth. The chemical composition of soft formation soils can also be determined from the sample if provisions are made to ensure that clean, decontaminated tools are used in the sample gathering procedure. Field-extruded samples can be field-screened or laboratory-analyzed to determine the chemical composition of soil and contained pore fluids. Using sealed or protected sampling tools, cased boreholes, and proper advancement techniques can help in the acquisition of good representative samples. A general knowledge of subsurface conditions at the site is beneficial.
5.3 The use of this practice may not be the correct method for inv...
SCOPE
1.1 This practice covers a procedure for sampling of cohesive, organic, or fine-grained soils, or combination thereof, using a thin-walled metal tube that is inserted into the soil formation by means of a hydraulically operated piston. It is used to collect relatively intact soil samples suitable for laboratory tests to determine structural and chemical properties for geotechnical and environmental site characterizations.
1.1.1 Guidance on preservation and transport of samples in accordance with Practice D4220/D4220M may apply. Samples for classification may be preserved using procedures similar to Class A. In most cases, a thin-walled tube sample can be considered as Class B, C, or D. Refer to Guide D6169/D6169M for use of the hydraulically operated stationary piston soil sampler for environmental site characterization. This sampling method is often used in conjunction with rotary drilling methods such as fluid rotary; Guide D5783; and hollow stem augers, Practice D6151/D6151M. Sampling data shall be reported in the field log in accordance with Guide D5434.
1.2 The hydraulically operated stationary piston sampler is limited to soils and unconsolidated materials that can be penetrated with the available hydraulic pressure that can be applied without exceeding the structural strength of the thin-walled tube. This standard addresses typical hydraulic piston samplers used on land or shallow water in drill holes. The standard does not address specialized offshore samplers for deep marine applications that may or may not be hydraulically operated. This standard does not address operation of other types of mechanically advanced piston samplers. For information on other soil samplers, refer to Guide D6169/D6169M.

SIGNIFICANCE AND USE
4.1 This practice provides basic criteria for the development and operation of a certification organization, selection of examination material for a written examination, and the scope and details of a performance test. The qualifications of the examiner and limitations on the relationship between the examiner and the examinee are given in this practice.
4.2 The basic criteria provided by this practice is intended to be supplemented by more specific criteria serving the requirements of the certification organization.
4.3 It is unrealistic and unintended that each individual be certified for every test the employing agency performs. Rather, it should be a goal of an agency that a majority of personnel normally performing a given test are certified. Depending on the purpose of the testing, it may be appropriate for the client to specify whether or not a certified technician should perform a given test.
4.4 Although this practice calls for certification specific to a single ASTM test method, it is not intended the certification organization avoid grouping related test methods in the interest of efficiency.
SCOPE
1.1 This practice provides a guide for evaluation and certification procedures for personnel engaged in testing soil and rock in accordance with ASTM test methods and is intended for use by independent organizations providing certification services.
1.2 Qualifications for certification candidates, qualifications of those administering the certification examinations, methods of administering the certification tests, and certain certification organization operating requirements are given.
1.3 Certification is specific to a single ASTM test method. A monitored written examination and a monitored performance examination are normally required.
Note 1: Personnel certification may be an important aspect of a quality system as described in Practice D3740. Certification of personnel is one means of meeting personnel qualifications given in Practice D3740.
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 practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

SIGNIFICANCE AND USE
5.1 Test methods A and B are used to estimate the permanganate natural oxidant demand exerted by the soil or aquifer solids by determining the quantity of potassium permanganate that is consumed by naturally occurring species as a function of time. Test Method C is used to estimate the permanganate total oxidant demand exerted by soil, aquifer solids, chemical contaminants or any other reduced species by determining the quantity of potassium permanganate that is consumed by all components of the bulk aquifer as a function of time. Typically, the measurement of oxidant demand is used to screen potential sites for in situ chemical oxidation (ISCO) with permanganate (Test Methods A and C) and provide information to aid in the design of remediation systems (Test Methods B and C).
5.2 While some oxidizable species react relatively quickly (that is, days to weeks), others react more slower (weeks to months). Consequently, the PNODt is expected to be some fraction of the PNODmax.
5.3 For ISCO injection applications, the PNOD may overestimate the demand exerted due to mass transport related issues. For soil blending applications, the PNOD is a more accurate measure of the demand exerted due to better mass to oxidant contact.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/and so forth.
SCOPE
1.1 These test methods cover the estimation of the permanganate natural oxidant demand (PNOD) through the determination of the quantity of potassium permanganate (KMnO4) that organic matter and other naturally occurring oxidizable species present in soil or aquifer solids will consume under specified conditions as a function of time. Oxidizable species may include organic constituents and oxidizable inorganic ions, such as ferrous iron and sulfides. The following test methods are included:
Test Method A—48-hour Permanganate Natural Oxidant Demand
Test Method B—Permanganate Natural Oxidant Demand Kinetics
Test Method C—Permanganate Total Oxidant Demand
1.2 These test methods are limited by the reagents employed to a permanganate natural oxidant demand (PNOD) of 40 g KMnO4 per kg soil or aquifer solids after a period of 48 hours (Methods A and C) or two weeks (Method B).
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Maintaining a moist environment by gradually releasing absorbed moisture helps provide a beneficial growth environment. The ability of a product to absorb moisture is commonly specified. This test method can be used for quality control and to determine product conformance to a specification.
5.2 Change in mass of RECPs submerged in water may be used to control the quality of many RECPs. Change in mass of RECPs submerged in water has not been proven to relate to field performance for all materials.
5.3 The change in mass of RECPs submerged in water may vary considerably depending on the composition of the materials used in the product or due to inconsistency within the product. This test method enables the characterization and control of product consistency.
5.4 This test method may be used to determine the effect of different component materials and makeup of RECPs on the change in mass when submerged in water.
5.5 This test method may be used for acceptance testing of commercial shipments of RECPs. Comparative tests as directed in 5.6 may be advisable.
5.6 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 shall conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the evaluation of bias. As a minimum, the two parties shall take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question. The test specimens shall be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories shall be compared using Student’s t-test for unpaired date and an acceptable probability level ch...
SCOPE
1.1 This test method measures the change in mass of a rolled erosion control product when specimens are submerged in water for a prescribed period of time. The change in mass is reported as a percentage of the original dry mass of the specimen.
1.2 Units—The values stated in either SI units or inch-pound units [given in brackets] 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. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.
1.2.1 It is common practice in the engineering/construction profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf). This practice implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated, this standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass. However, the use of balances and scales recording pounds of mass (lbf) or recording density in lbm/ft3 shall not be regarded as nonconformance with this standard.
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method.
1.3.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for t...
