1.1 该分类体系涵盖了用作连接材料的热塑性材料，用于在相似或不同材料之间创建接头，以生产拟拆卸和/或重新组装的成品或零件。 1.2 这类材料可以断开产品不同部分或层的连接，以进行翻新、维修，并完全回收和再循环连接的材料，例如在产品寿命结束时，实现宝贵资源的再利用，从而减少对环境的不利影响。 1.3 该分类系统中包含的属性是识别所涵盖材料所需的属性。可能还有其他必要的要求来确定对专业应用程序重要的特定特性。 指定它们的一种方法是使用第节中给出的后缀 5. . 1.4 该分类系统和随后的线形标注（规范）旨在提供一种方法，指出用于制造成品或零件的塑料材料。它不用于选择材料。材料选择最好由在塑料领域具有专业知识的人员在仔细考虑零件所需的设计和性能、其将暴露的环境、将采用的制造工艺、所涉及的成本和材料的固有特性（本分类系统所涵盖的特性除外）后进行。 1.5 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位。 1.6 以下预防性警告仅适用于试验方法部分第节 11 ，属于该分类系统。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 注1: 应用实例是完全可回收的床垫和地板覆盖物。这些产品可以通过加热分解成不同的零件，以便在产品寿命结束时对连接材料进行翻新、维修和完全回收和再循环。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This classification system covers thermoplastic materials, used as joining materials, for the creation of joints between similar or dissimilar materials, to produce finished products or parts that are intended to be disassembled and/or reassembled. 1.2 This class of materials enables disconnection of the different parts or layers of a products for refurbishing, repair and full recovery and recycling of the joined materials, for instance at the end of life of the product(s), enabling the reuse of valuable resources, and hence reducing adverse impact on the environment. 1.3 The properties included in this classification system are those required to identify the materials 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: Application examples are fully recyclable mattresses and floor coverings. These products can be disassembled into its different parts, by using heat, for refurbishing, repair and full recovery and recycling of the joined materials at the end of the product’s life. 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.
