1.1本试验方法涵盖了剪切速率相关粘合剂表观粘度的测量。 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。 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====== 测量原理基于表观粘度随剪切速率变化的可逆等温变化。 在标准化条件下，使用心轴、圆盘、T形棒或同轴圆柱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，在粘度计刻度盘上获得读数。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. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 ====== The principle of measurement is based upon a reversible isothermal change in apparent viscosity with change in rate of shear. Measurement is performed with a spindle, disk, T-bar, or coaxial cylinder rotational viscometer under standardized conditions with rigid control of the time intervals of measurement. Readings are obtained on the viscometer dial scale 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.
