Standard Test Method for Axial Compression Test of Reinforced Plastic and Polymer Matrix Composite Vertical Members

Standard Test Method for Axial Compression Test of Reinforced Plastic and Polymer Matrix Composite Vertical Members

SIGNIFICANCE AND USE
5.1 The compressive properties obtained by axial compression will provide information such as: modulus of elasticity, stress at proportional limit and compressive strength for the end support, and lateral bracing condition tested.  
5.2 This test method addresses only full-sized specimens for determination of compressive strength and compressive modulus of elasticity intended for application to actual length members with end conditions and lateral bracing as intended.
Note 1: The effective length of the column with respect to buckling is affected by the end conditions. A fixed end condition results in an effective length for buckling that is less than the actual length of the column, by as much as 50 %.
SCOPE
1.1 This test method covers the evaluation of vertical members in axial compression for “full-sized” specimens with various end conditions with constant cross-sections throughout the length.  
1.2 This test method is limited to reinforced plastic and polymer matrix composite materials and covers the determination of the compressive properties of structural members. The method is intended primarily for members of rectangular cross section, but is also applicable to irregularly shaped studs, round posts, or special sections.  
1.3 This test method covers short-term axial load testing under standard indoor atmospheric conditions. It does not address: sampling, the ability of the material to carry a sustained long-term load, design load derivations, temperature effects, performance under freeze/thaw or salt spray exposure conditions, chemical/UV exposure effects, or engineering analysis/modeling needed to extrapolate the results to conditions other than those tested. Each of these factors, and potentially others, need to be considered by the design professional or product standard development committee before using the information generated by this test method to assess structural adequacy.  
1.4 Short sections are not covered in this test method and should be tested using a material test standard such as Test Method D6108 or Test Methods D198.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Methods for Compressive and Flexural Creep and Creep-Rupture of Plastic Lumber and Shapes

SIGNIFICANCE AND USE
5.1 Data from creep and creep-rupture tests are necessary to predict the creep modulus and strength of materials under long-term loads and to predict dimensional changes that have the potential to occur as a result of such loads.  
5.2 Data from these test methods can be used to characterize plastic lumber: for comparison purposes, for the design of fabricated parts, to determine long-term performance under constant load, and under certain conditions, for specification purposes.  
5.3 For many products, it is possible that there will be a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that product specification before using this test method. Table 1 in Classification D4000 lists the ASTM materials standards that currently exist.
SCOPE
1.1 These test methods cover the determination of the creep and creep-rupture properties of plastic lumber and shapes, when loaded in compression or flexure under specified environmental conditions. Test specimens in the “as-manufactured” form are employed. As such, these are test methods for evaluating the properties of plastic lumber or shapes as a product and not material property test methods.  
1.2 Plastic lumber and plastic shapes are currently made predominantly with recycled plastics. However, this test method would also be applicable to similar manufactured plastic products made from virgin resins where the product is non-homogenous in the cross-section.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given 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.
Note 1: There is no known ISO equivalent to this standard.

ASTM D5418-23(Test Method)
Standard Test Method for Plastics: Dynamic Mechanical Properties: In Flexure (Dual Cantilever Beam)

SIGNIFICANCE AND USE
5.1 This test method provides a simple means of characterizing the thermomechanical behavior of plastic compositions using a very small amount of material. Since small test specimen geometries are used, it is essential that the specimens be representative of the material being tested. The data obtained can be used for quality control and/or research and development purposes. For some classes of materials, such as thermosets, it can also be used to establish optimum processing conditions.  
5.2 Dynamic mechanical testing provides a sensitive means for determining thermomechanical characteristics by measuring the elastic and loss moduli as a function of frequency, temperature, or time. Plots of moduli and tan delta of a material versus these variables can be used to provide a graphic representation indicative of functional properties, effectiveness of cure (thermosetting-resin systems), and damping behavior under specified conditions.  
5.2.1 Observed data are specific to experimental conditions. Reporting in full (as described in this test method) the conditions under which the data was obtained is essential to assist users with interpreting the data an reconciling apparent or perceived discrepancies.  
5.3 This test method can be used to assess the following:  
5.3.1 The modulus as a function of temperature or aging, or both,  
5.3.2 The modulus as a function of frequency,  
5.3.3 The effects of processing treatment, including orientation, induced stress, and degradation of physical and chemical structure,  
5.3.4 Relative resin behavioral properties, including cure and damping,  
5.3.5 The effects of substrate types and orientation (fabrication) on elastic modulus,  
5.3.6 The effects of formulation additives that might affect processability or performance,  
5.3.7 The effects of annealing on modulus and glass transition temperature,  
5.3.8 The effect of aspect ratio on the modulus of fiber reinforcements, and  
5.3.9 The effect of fillers, additives ...
SCOPE
1.1 This test method outlines the use of dynamic mechanical instrumentation for determining and reporting the viscoelastic properties of thermoplastic and thermosetting resins and composite systems in the form of rectangular bars molded directly or cut from sheets, plates, or molded shapes. The elastic modulus data generated is used to identify the thermomechanical properties of a plastics material or composition.  
1.2 This test method is intended to provide a means for determining the viscoelastic properties of a wide variety of plastics using nonresonant, forced-vibration techniques as outlined in Practice D4065. In particular, this method identifies the procedures used to measure properties using what is known as a dual-cantilever beam flexure arrangement. Plots of the elastic (storage) modulus, loss (viscous) modulus, and complex modulus, and tan delta as a function of frequency, time, or temperature are indicative of significant transitions in the thermomechanical performance of the polymeric material systems.  
1.3 This test method is valid for a wide range of frequencies, typically from 0.01 Hz to 100 Hz.  
1.4 Test data obtained by this test method are relevant and appropriate for use in engineering design.  
1.5 The values stated in SI units are to be regarded as standard.  
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.
Note 1: There is no known ISO equivalent to this standard.

Standard Practice for Xenon-Arc Exposure of Plastics Intended for Outdoor Applications

SIGNIFICANCE AND USE
4.1 The ability of a plastic material to resist deterioration of its electrical, mechanical, and optical properties caused by exposure to light, heat, and water can be very significant for many applications. This practice is intended to induce property changes associated with end-use conditions, including the effects of daylight, moisture, and heat. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.  
4.2 Caution—Variations in results are possible when operating conditions are varied within the accepted limits of this practice. Therefore, all references to the use of this practice must be accompanied by a report prepared in accordance with Section 9 that describes the specific operating conditions used. Refer to Practice G151 for detailed information on the caveats applicable to use of results obtained in accordance with this practice.
Note 2: Additional information on sources of variability and on strategies for addressing variability in the design, execution, and data analysis of laboratory-accelerated exposure tests is found in Guide G141.  
4.3 Reproducibility of test results between laboratories has been shown to be good when the stability of materials is evaluated in terms of performance ranking compared to other materials or to a control.6,7 Therefore, exposure of a similar material of known performance (a control) at the same time as the test materials is strongly recommended. It is preferable that the number of specimens of the control material be the same as that used for test materials. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.  
4.4 Test results will depend upon the care that is taken to operate the equipment in accordance with Practice G155. Significant factors include regulation of line voltage, freedom from salts or other d...
SCOPE
1.1 This practice covers specific procedures and test conditions that are applicable for xenon-arc exposure of plastics conducted in accordance with Practices G151 and G155. This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
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.
Note 1: This practice and ISO 4892-2 address the same subject matter, but differ in technical content.  
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 Methods for Mechanical Fasteners in Plastic Lumber and Shapes

SIGNIFICANCE AND USE
6.1 The resistance of plastic lumber and shapes to direct withdrawal of nails, staples, or screws is a measure of its ability to hold or be held to an adjoining object by means of such fasteners. Factors that affect this withdrawal resistance include the physical and mechanical properties of the plastic lumber and shapes; the size, shape, and surface condition of the fasteners; the speed of withdrawal; physical changes to plastic lumber and shapes or fasteners between time of driving and time of withdrawal; orientation of fiber axis; the occurrence and nature of prebored lead holes; and the temperatures during insertion and withdrawal. These factors will be as circumstances dictate, and representative of the normal manufacturing process.  
6.2 By using a standard size and type of nail, staple, or screw, withdrawal resistance of plastic lumber and shapes can be determined. Throughout the method this is referred to as the basic withdrawal test. Similarly, comparative performances of different sizes or types of nail, staple, or screw can be determined by using a standard procedure with a particular plastic lumber and shape, which eliminates the plastic lumber and shapes product as a variable. Since differences in test methods can have considerable influence on results, it is important that a standard procedure be specified and adhered to, if test values are to be related to other test results.
SCOPE
1.1 These test methods cover the evaluation of fastener use with “as manufactured” plastic lumber and shapes through the use of two different testing procedures.  
1.2 The test methods appear in the following order:    
Sections  
Test Method A—Nail, Staple, or Screw Withdrawal Test  
4 to 13  
Test Method B—Nail, Staple, or Screw Lateral Resistance Test  
14 to 22  
1.3 Plastic lumber and plastic shapes are currently made predominately from recycled plastics. However, these test methods would also be applicable to similar manufactured plastic products made from virgin resins where the product is non-homogeneous in the cross-section.  
1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information 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.
Note 1: There is no known ISO equivalent to this standard.

Standard Specification for Sprayed Slurries, Foams and Indigenous Materials Used As Alternative Daily Cover for Municipal Solid Waste Landfills

ABSTRACT
This specification defines procedures for determining the performance of certain landfill daily cover materials such as sprayed slurries, foams, and indigenous materials generally described as an alternative daily cover (ADC) for municipal solid waste landfills. It is not applicable to other types of landfills and to geosynthetics used as an ADC. It addresses the evaluation of an ADC and its ability to control fires and odors and whether or not the cover contains materials that present a threat to human health and the environment. Materials shall be tested at accredited laboratories to determine the physical properties such as potential for fire production, water vapor permeance, toxicity, and leaching potential. The control of disease vectors and blowing litter shall be evaluated by observation while scavenging shall be controlled by security procedures and other operating practices.
SCOPE
1.1 This specification defines procedures for determining the performance of certain landfill daily cover materials generally described as an alternative daily cover (ADC). This specification applies only to slurries or foams that are spray applied, or indigenous materials that are placed onto the working face of a municipal solid waste landfill (MSWLF) unit as a cover. It is not applicable to other types of landfills nor geosynthetics used as an ADC.  
1.2 This standard addresses the evaluation of an ADC and its ability to control fires and odors and whether or not the cover contains materials that present a threat to human health and the environment. The control of disease vectors and blowing litter can be evaluated by observation, and scavenging is controlled by security procedures and other operating practices.  
1.3 The U.S. Environmental Protection Agency (EPA) promulgated regulations under the Resource Conservation and Recovery Act, Subtitle D, which establish criteria for municipal solid waste landfills (MSWLF). These regulations became effective October 9, 1991. The cover material requirements of these regulations are set forth in 40 Code of Federal Regulations, Section 258.21 as follows:
(a) “Except as provided in paragraph (b) of this section, the owners or operators of all MSWLF units must cover disposed solid waste with 6 in. (152.4 mm) of earthen material at the end of each operating day, or at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, and scavenging.”
(b) “Alternative materials of an alternative thickness (other than at least 6 in. (152.4 mm) of earthen material) may be approved by the Director of the Solid Waste Regulatory Agency of an approved State if the owner or operator demonstrates that the alternative material and thickness control disease vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment.”  
1.3.1 These federal regulations have the force of the law, and it is the purpose of this specification to define the test procedures necessary to comply with these regulations.  
1.3.2 In order for a MSWLF landfill operator to obtain approval for use of an ADC, the operator must supply performance data to the state Solid Waste Regulatory Agency. In general, the technique used to obtain this permission involves applying to the state Solid Waste Regulatory agency for a sanitary MSWLF operating permit modification.
Note 1: Manufacturers will provide performance data for their product.  
1.3.3 Parties interested in the evaluation technology described in the Standard Practice should include MSWLF operators, engineering firms, local, state, and federal Solid Waste Regulatory Agencies, and manufacturers and vendors of ADC materials.  
1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastic field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification system.  
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 The following precautionary caveat pertains only to the test methods portion, Section 11, of this classification system. 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.
Note 1: This classification system is similar to ISO 16396-1/-2,
although the technical content is significantly different.
Note 2: The materials covered by this classification system include a subset of polyamides defined as polyphthalamides (PPA) as in 3.2.1, some of which are also classified in ASTM D5336. Specifically, groups 7, 10, 12, 13, 14, 15 and 17 in this standard are PPA materials. ASTM D5336 gives further details relating to groups 10, 12 and 13.  
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 D7568-23(Specification)
Standard Specification for Polyethylene-Based Structural-Grade Plastic Lumber for Outdoor Applications

SCOPE
1.1 This specification covers a type of plastic lumber product, defined as polyethylene-based structural-grade plastic lumber (SGPL), for use as main framing members, including joists, stringers, beams, columns; and secondary framing members, including planking, posts and bracing; in outdoor structures such as decks, boardwalks, docks, and platforms.  
1.2 This specification is applicable to solid, rectangular SGPL products where polyethylene resin (non cross-linked) is the continuous phase and is at least 50 % of the product (by weight).  
1.3 This specification is not applicable to plastic lumber products containing cellulosic materials as additives, fillers or fiber reinforcements.  
1.4 SGPL products covered by this specification shall not be used as tensile members.  
1.5 SGPL products are produced using several different manufacturing processes. These processes utilize a number of polyethylene resin material systems that include varying proportions of fillers, fiber reinforcements, and other chemical additives.  
1.6 Due to thermodynamic effects that result in outer-surface densification during manufacture, SGPL products are typically non-homogeneous in the cross-section. This standard does not address materials that have been modified from their original cross-section.  
1.6.1 The cross-section non-homogeneity is addressed in the material property assessments in this document only for applications in which the product cross-section is not modified by cutting, notching, or drilling. For products modified in this manner, additional engineering considerations are required and they are beyond the scope of this document.  
1.7 For purposes of this standard, an SGPL product is a specific combination of polyethylene resin, together with fillers, reinforcements, and additives. Each formulation is to be identified as a distinct and different product, to be tested and evaluated separately.  
1.8 Diverse and multiple combinations of both virgin and recycled polyethylene material systems are permitted in the manufacture of SGPL products.  
1.9 Fiber reinforcements used in SGPL include manufactured materials such as fiberglass (chopped or continuous), carbon, aramid and other polymeric materials.  
1.10 A wide variety of chemical additives are typically added to SGPL formulations. Examples include colorants, chemical foaming agents, ultraviolet stabilizers, fire retardants, lubricants, anti-static products, heat stabilizers, and coupling agents.  
1.11 Diverse types and combinations of filler systems are permitted in the manufacturing of SGPL products. Fillers that cause the product to fail the requirements of 6.13 are not permitted in the manufacturing of SGPL products.  
1.12 In order for a product to be classified as SGPL, it must meet the minimum stress and modulus criteria consistent with the specific product as marked, and additionally the properties specified in Section 6 of this specification.  
1.13 This specification pertains to SGPL where any reinforcement is uniformly distributed within the product. When reinforcement is not uniformly distributed, the engineering issues become substantially more complex. For this reason, such products are not covered in this document.  
1.14 Products that fail at strains of less than 0.02 (2 %) when tested in flexure in accordance with 6.6 are not compatible with the underlying assumptions of Annex A1 and are beyond the scope of this standard (see Note 1).
Note 1: Calculation of time-dependent properties in Annex A1 is based on the assumption that the product does not fail in a brittle manner. The 2 % strain limit was selected based on the judgment of the task group members that created Annex A1.  
1.15 This specification addresses issues relevant to a buyer’s requirements for SGPL products and has therefore been developed in the format of a procurement specification.  
1.16 Criteria for design are included as part of this specification for SGPL product...
