Причина отмены 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).

Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in January 2023 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

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.

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.
