ASTM D3349-21(Test Method)
Standard Test Method for Absorption Coefficient of Ethylene Polymer Material Pigmented with Carbon Black

SIGNIFICANCE AND USE
4.1 The absorption coefficient of polyolefin polymer pigmented with carbon black is useful to judge the degree and uniformity of dispersion of the pigment, and the adequacy of the quantitative level of pigment addition. These factors are used to predict the performance of the polymer material in response to prolonged exposure to ultraviolet light as evidenced by minimal changes in specific properties.
Note 1: This test method was developed to evaluate ethylene polymer materials pigmented with small particle size carbon blacks suitable for UV protection. It is not known how accurate and reproducible the test would be with larger (35 nm or greater) particle size blacks. However, for larger particle sizes of carbon black, such as furnace black at 275 nm, when there is at least 5 or higher percent of carbon black, the material pigmented as such has suitable UV protection.
SCOPE
1.1 This test method measures the amount of light transmitted through a film of carbon black pigmented ethylene polymer.  
1.2 After calculation of the amount of light and film thickness, an absorption coefficient is calculated.  
1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those 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 Classification System for Thermoplastic Elastomer-Ether-Ester Molding and Extrusion Materials (TEEE)

SCOPE
1.1 This classification system covers segmented block copolyether-ester elastomers suitable for molding and extrusion.  
1.2 This classification system allows for the use of segmented block copolyether-ester elastomers that are recycled provided that the requirements as stated in this classification system are met. The proportions of recycled material used, as well as the nature and amount of any contaminant, however, cannot be covered practically in this specification.  
1.3 The properties included in this classification system are those required to identify the compositions covered. It is possible that there are other requirements necessary to identify particular characteristics important to specialized applications. One way of specifying them is by using the suffixes as given in Section 5.  
1.4 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 is best 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.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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 standard, ISO 20029-1, and ISO 20029-2 address the same subject matter, but differ in technical content.  
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 F3181-16(2023)(Test Method)
Standard Test Method for The Un-notched, Constant Ligament Stress Crack Test (UCLS) for HDPE Materials Containing Post- Consumer Recycled HDPE

SIGNIFICANCE AND USE
4.1 This test method is a way to evaluate the effects of contaminant particles found in HDPE products containing PCR-HDPE, primarily corrugated pipe. Particles of significant number, size and shape can reduce the slow crack growth resistance of the products. This test is performed in water without a controlled defect such as a notch. Since there is no notch, it is not necessary to use a surfactant in the water bath. It is a constant load test.  
4.2 This test may be used to evaluate various blends of recycled and virgin materials. For example, a material with high stress crack resistance and few contaminants can be blended with materials that are less resistant to cracking to enhance the overall stress crack resistance of the blend.  
4.3 The test can be conducted at various temperature and stress conditions. If at least three (3) different temperature/stress conditions are evaluated, an estimate of the service lifetime of the material can be predicted with the use of bi-directional shifting or the rate process method.  
4.4 The test can also be performed under a single applied load and a single temperature to create a single point test useful for comparative purposes as well as for quality control.
SCOPE
1.1 This test method covers an un-notched constant ligament stress (UCLS) test for use with HDPE materials that contain post-consumer recycled HDPE (PCR-HDPE). Contaminants in the PCR-HDPE can initiate stress cracks at elevated temperatures, and this test method evaluates the response of these materials to a constant applied stress.  
1.2 The test method is focused on HDPE corrugated pipe containing PCR-HDPE, but can be used in other applications where PCR-HDPE is used.  
1.3 The test utilizes the same devices used to perform the NCTL test (Test Method D5397) and the NCLS test (Test Method F2136), but the test is conducted with different specimens and with the use of water instead of a surfactant solution. The test specimen is larger than standard NCLS and NCTL specimens to increase the number of contaminant particles in the specimen that might grow cracks.  
1.4 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.  
1.5 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.
