1.1本试验方法包括测量液体形式的粘合剂及其成分的密度（每加仑重量）。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法特别适用于流体粘度过高或成分太易挥发而无法测定比重平衡的情况。

1.1 This test method covers the measurement of density (weight per gallon) of adhesives, and components thereof, when in liquid form. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is particularly applicable where the fluid has too high a viscosity or where a component is too volatile for a specific gravity balance determination.
