1.1 本规范涵盖压缩模塑热固性脲醛模塑化合物，进一步定义见 3.1 . 1.2 以国际单位制表示的数值应视为标准。 注1: 本规范中包含的特性是识别所涵盖的模塑料类型所需的特性。可能还有其他必要的要求来识别特定特征。转移或注射成型通常会导致与压缩成型不同的物理和电气特性。 1.3 以下安全隐患警告仅适用于试验方法部分第节 7. ，本规范: 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2: ISO 2112-1977（E）与本规范类似，但不等同。产品分类和特性不一样。 1.4 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 specification covers compression molding thermosetting, urea-formaldehyde molding compounds as further defined in 3.1 . 1.2 The values stated in SI units are to be regarded as the standard. Note 1: The properties included in this specification are those required to identify the types of molding compounds covered. There may be other requirements necessary to identify particular characteristics. Transfer or injection molding will usually result in different physical and electrical characteristics than compression molding. 1.3 The following safety hazards caveat pertains only to the test method portion, Section 7 , of this specification: 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 2: ISO 2112-1977(E) is similar but not equivalent to this specification. Product classification and characterization are not the same. 1.4 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.
