1.1 本规程提供了一种用于估计摊铺或涂覆操作中应用的液体粘合剂数量的程序。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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。 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。 ====意义和用途====== 4.1 对于粘附物的粘合，粘合剂的用量至关重要，重要的是要理解，这种做法不能确保粘附物表面上有足够的粘合剂。 4.2 该实践可用于补充工业用途，例如目视检查扩散或使用密耳测厚仪。 4.3 在实验室和工业操作中，可以使用这种做法手动或机械应用粘合剂，以节省成本。

1.1 This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. 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 For the bonding of adherends, the amount of adhesive present is critical and it is important to understand that this practice does not ensure sufficient adhesive is present on the adherend surface. 4.2 This practice can be used to supplement industry uses such as that of visually checking the spread or the use of mil-thickness gages. 4.3 In laboratory and industrial operations, hand or mechanical application of adhesives can be duplicated for cost savings using this practice.
