ASTM F3308/F3308M-2019 无压设备用聚乙烯管道中再生材料取样和测试频率规程 Standard Practice for Sampling and Testing Frequency for Recycled Materials in Polyethylene (PE) Pipe for Non-Pressure Applications

1.1 This practice covers requirements and sampling frequency for the use of post-consumer and post-industrial recycled plastic materials in polyethylene (PE) pipe used in storm drainage, storm sewer and sanitary sewer applications.

1.2 The requirements of this practice provide definitions, requirements and test protocols for recycled plastic materials to be used in the production of polyethylene (PE) pipe for gravity flow applications.

1.3 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 independent of the other. Combining values from the two systems may result in non-conformance with the standard.

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 prio
