(Specification)Standard Specification for Wipe Sampling Materials for Lead in Surface Dust
Standard Specification for Wipe Sampling Materials for Lead in Surface Dust
SCOPE
1.1 This specification covers requirements for wipe materials that are used to collect settled dusts on hard surfaces for the subsequent determination of lead.
1.2 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.
