Significance and Use | ||
5.1?Most occupational exposure assessment methods require the use of personal sampling pumps to collect air samples at typical sampling flow rates, with sampling volumes specified by (a) particular procedure(s). The precision and bias of these methods are directly affected by the precision and bias of the pumps used in the measurement of the air volume(s) sampled. |

1. Scope | ||
1.1?This practice describes the setting and verification of flow rate for sampling pumps commonly used for monitoring personal airborne exposures in the workplace. 1.2?This practice includes procedures for using working standard flow meters that are traceable to national or international standards, as well as those that are not. Traceable standards are preferred. 1.3?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
