1.1本试验方法用于测定颗粒载体的持液能力（LHC）。 1.2以国际单位制或英寸-磅单位表示的数值应视为标准值。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。 有关具体的预防说明，请参阅第节。 ====意义和用途====== 本试验方法主要针对LHC大于5.0%的颗粒载体设计。对于LHC小于5.0%的载体，可以根据需要降低添加的合适流体的增量。 本试验方法适用于4至100目（4.75至0.150 mm）范围内的颗粒。

1.1 This test method is used to determine the liquid holding capacity (LHC) of granular carriers. 1.2 The values stated in either SI or inch-pound units are to be regarded as 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. For specific precautionary statements, see Section. ====== Significance And Use ====== This test method has been designed principally for granular carriers with LHC greater than 5.0 %. The incremental amount of suitable fluid added can be adjusted down as needed for carriers with LHC less than 5.0 %. This test method is applicable to granules in the range from 4 to 100 mesh (4.75 to 0.150 mm).
