【国外标准】 Standard Practice for Dermal Wipe Sampling for the Subsequent Determination of Metals and Metalloids

5.1 This practice is intended for the collection of samples of skin contamination to be used for the estimation of dermal exposure to metals and metalloids. The practice is meant for use in the collection of dermal samples that are of interest in hazard evaluation, risk assessment, or other purposes. This practice is meant to provide a standardized means for estimating exposures to body parts that are potentially exposed via dermal contact with airborne or surface contaminants, or both.5.2 The techniques described in this practice may not accurately reflect the transferability or bioavailability of metal or metalloid residues by way of dermal contact.5.3 Additional information on the principles and methods for the measurement of dermal exposure can be found in ISO TR 14294.1.1 This practice describes a procedure for the wet wiping of potentially exposed skin of workers for the subsequent determination of metals and metalloids.NOTE 1: For guidance on collection of wipe samples on surfaces other than skin, refer to Guide D7659.1.2 This practice does not address the sampling design criteria that are used for hazard evaluation, risk assessment, or other purposes.1.3 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This practice offers a set of instructions for performing one or more specific operations. This practice cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This practice is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this practice be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the practice has been approved through the ASTM consensus process.1.6 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.1.7 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.
