Standard Practice for Sampling and Testing Frequency for Recycled Materials in Polyethylene (PE) Pipe for Non-Pressure Applications
4.1 The utilization of recycled materials in non-pressure thermoplastic pipe presents a potentially large outlet for this what is typically classified “waste” material. The proper use and qualification of this material is critical in assuring its long-term performance from both a structural and durability standpoint.
4.2 This practice defines minimum requirements and testing protocols and frequencies for these recycled materials with respect to their utilization in final thermoplastic pipe products. Each specific pipe standard has unique criteria that must be met in addition to the items described in this practice.
4.3 The purpose of this specification is for characterization of recycled plastics only and does not establish performance guidelines for such materials. Product specifications may be used in conjunction with this specification to establish performance specifications for a defined end-use and specific material type.
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.
Note 1: Non-pressure applications pertain principally to any municipal or private facilities for land drainage, storm drainage, storm sewer, culvert and sanitary sewer applications. The products utilizing the criteria under this practice are not intended for any pressure pipe applications, such as water or gas pipelines.
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 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.
