1.1 本规范涵盖了用于将木材粘附到木材上的酪蛋白和其他蛋白质混合粘合剂。本规范涵盖的粘合剂类型是一种干粉或颗粒状产品，由酪蛋白或酪蛋白和其他蛋白质源的混合物组成，当混合物加入水中时，需要使用必要的干化学品来溶解。 注1: 虽然术语 酪蛋白粘合剂 在本规范中，历史上，粘合剂子类在 1.1 被称为酪蛋白胶。参见术语 D907 , 粘合剂类型 . 1.2 局限性-- 熟酪蛋白粘合剂不在本规范范围内。 1.3 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 以下安全隐患警告仅适用于测试方法部分，第节 8. 通过 13 ，根据本规范 :本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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 casein and other protein-blend adhesives for use adhering wood to wood. The adhesive type covered by this specification is a dry powder or granular product comprising a mixture of casein, or casein and other protein source, with the necessary dry chemicals to effect solution when the mixture is added to water. Note 1: Although the term casein adhesive is used throughout this specification, historically, the adhesive subclass described in 1.1 has been known as casein glue. See Terminology D907 , adhesive types . 1.2 Limitations— Cooked casein adhesives are not covered by this specification. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The following safety hazards caveat pertains only to the test method portion, Sections 8 through 13 , 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. 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.
