1.1 本试验方法包括使用旋转粘度计测量剪切速率相关粘合剂的表观粘度。 1.2 以国际单位制表示的数值应视为标准值。本标准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 测量原理基于表观粘度的可逆等温变化以及旋转速度变化引起的剪切速率变化。 4.2 在标准化条件下，使用旋转粘度计进行测量，并严格控制测量时间间隔。在每个转速的1分钟结束时获得粘度读数。在不停止仪器的情况下，从最低速度切换到最高速度，并返回到最低速度。

1.1 This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives using a rotational viscometer. 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. 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 The principle of measurement is based upon a reversible isothermal change in apparent viscosity with change in rate of shear produced by a change in rotational speed. 4.2 Measurement is performed with a rotational viscometer under standardized conditions with rigid control of the time intervals of measurement. Viscosity readings are obtained at the end of 1 min for each rotational speed. Changes from the lowest speed to the highest speed, and return to the lowest speed, are made without stopping the instrument.
