Other types of sieve shakers are also available, but their precision and reproducibility have not been determined.1.3 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.【中国标准分类号】: H71【国际标准分类号】: 77_16【页数】: 4P.;A4【正文语种】:
