【国外标准】 Standard Specification for Wipe Sampling Materials for Lead in Surface Dust

This specification covers requirements for wipe sampling materials that are used to collect settled dusts on surfaces for the subsequent determination of lead. The wipes shall be tested for conformance to background lead, lead recoverability, collection efficiency, ruggedness which shall be determined using butted vinyl-composite floor tiles as a test surface, moisture content, coefficient of variation in mass, linear dimensions such as mean area and mean length, and mean thickness requirements.1.1 This specification covers requirements for wipes that are used to collect settled dusts on surfaces for the subsequent determination of lead.1.2 For wipe materials used for the determination of beryllium in surface dust refer to Specification D7707. This is mentioned to insure that users of wipes recognize that there is some relationship between the analytical backgrounds found in wipes and the analyte of interest.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.
