1.1 本规范涵盖了具有再生聚乙烯含量（消费后或工业后）和不含再生聚乙烯含量的聚乙烯波纹管和管件产品的最低物理性能的识别。本规范的功能不是为设计目的提供特定的工程数据、规定制造公差或确定特定应用的适用性。 1.2 聚乙烯波纹管和管件是热塑性的，可再加工和回收( 注2 ). 本规范允许生产具有回收聚乙烯含量的这些产品，前提是满足本规范的最低性能要求。 1.3 本标准适用的聚乙烯波纹重力流（无压力）管和管件产品仅在挤出或成型过程中完全配制。 正是在这个过程中，回收的聚乙烯材料单独使用，或与原始（未着色）聚乙烯材料混合使用，并与色料/母料或其他添加剂结合使用。本文件中提出的要求适用于最终配制/制造的管道和配件产品。 注1: 本规范中的注释仅供参考，不应视为本规范的一部分。 注2: 有关再生塑料的信息和定义，请参阅指南ISO 15270。 1.4 制造商应采取质量控制措施。看见 附件A1 质量控制的一般要求。 注3: 目前还没有与该标准等效的ISO。 1.5 以国际单位制表示的数值应视为标准。括号中给出的值是对英寸的数学转换- 磅单位，仅供参考。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the identification of minimum physical properties of polyethylene corrugated pipe and fittings products both with recycled polyethylene content (post-consumer or post-industrial) and without recycled content. It is not the function of this specification to provide specific engineering data for design purposes, to specify manufacturing tolerances, or to determine suitability for use for a specific application. 1.2 Polyethylene corrugated pipe and fittings, being thermoplastic, are re-processable and recyclable ( Note 2 ). This specification allows for the manufacture of these products with recycled polyethylene content, provided the minimum performance requirements of this specification are met. 1.3 The polyethylene corrugated gravity flow (non-pressure) pipe and fittings products to which this standard is to be applied are only fully formulated during the extrusion or molding process. It is in this process where the recycled polyethylene materials are used either alone or blended with virgin (unpigmented) polyethylene materials and combined with color concentrates/masterbatches or other additives. The requirements presented in this document apply to the final formulated/manufactured pipe and fittings products. Note 1: The notes in this specification are for information only and shall not be considered part of this specification. Note 2: See Guide ISO 15270 for information and definitions related to recycled plastics. 1.4 Quality-control measures are to be taken by manufacturers. See Annex A1 for general requirements on quality control. Note 3: There is no known ISO equivalent to this standard. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units and are given for informational purposes only. 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. 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.
