The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. If you feel that your comments have not received a fair hearing astk should make your views known to the ASTM Committee on Standards, at the address shown below. Combining values from the two systems may result in nonconformance with the standard. 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.
