Standard Test Method for Gel Time of Solventless Varnishes 无溶剂清漆凝胶时间的标准试验方法
发布日期: 2023-10-01
1.1 本试验方法包括测定与催化剂混合的无溶剂清漆(如果需要)在高温下的凝胶时间。这里有两种方法。方法A的新设备不再可用。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 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。 有关具体的预防措施说明,请参阅第节 6. 。 注1: 尽管本标准和IEC 60455-2在方法或细节上有所不同,但使用两者获得的数据在技术上是等效的。 1.4 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。 ===意义和用途====== 4.1 凝胶时间对于确定批次均匀性和某些加工特性非常重要。它表示保质期和保质期。
1.1 This test method covers the determination of the gel time of a solventless varnish mixed with a catalyst, if required, and exposed to elevated temperature. There are two methods presented here. New equipment for Method A is no longer available. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. For a specific precaution statement, see Section 6 . Note 1: Although this standard and IEC 60455–2 differ in approach or detail, data obtained using either are technically equivalent. 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. ====== Significance And Use ====== 4.1 Gel time is important in determining batch uniformity and some processing characteristics. It is indicative of pot life and shelf life.
