1.1 本试验方法包括使用旋转粘度计（实验室方法）在1.0 mPa·s至1000 mPa·s（1.0至1000 cP）范围内测定催化化学灌浆的粘度。 1.2 所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 1.2.1 本标准中用于规定如何收集/记录或计算数据的程序被视为行业标准。此外，它们代表了通常应保留的有效数字。所使用的程序不考虑材料变化、获取数据的目的、特殊目的研究或对用户目标的任何考虑； 通常的做法是增加或减少报告数据的有效位数，以与这些考虑因素相称。考虑工程设计分析方法中使用的有效数字超出了本标准的范围。 1.3 以国际单位制表示的数值是标准值。括号中提供的其他装置是为了方便用户。 1.4 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====== 5.1 本试验适用于穿透土壤孔隙和岩石裂缝的材料。粘度本身不一定是灌浆渗透性的准确指标。

1.1 This test method covers the determination of viscosity of catalyzed chemical grouts with a rotational viscometer (laboratory method), over the range from 1.0 mPa·s to 1000 mPa·s (1.0 to 1000 cP). 1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 . 1.2.1 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose of obtaining the data, special purpose studies, or any consideratons for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. 1.3 The values stated in SI units are the standard. Other units provided in parentheses are for the convenience of the user. 1.4 This standard does not purport to address all of the safety problems, 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 ====== 5.1 This test is intended for materials that will penetrate soil voids and rock fissures. Viscosity alone is not necessarily an exact index of grout penetrability.
