1.1 本规程描述了工人潜在暴露皮肤的湿擦拭程序，用于随后测定金属和类金属。 注1: 有关在非皮肤表面收集擦拭样本的指南，请参阅指南 D7659 . 1.2 本规程不涉及用于危险评估、风险评估或其他目的的抽样设计标准。 1.3 本规程包含解释性注释，不属于本规程强制性要求的一部分。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本实践提供了一组用于执行一个或多个特定操作的说明。这种做法不能取代教育或经验，应与专业判断结合使用。并非本惯例的所有方面都适用于所有情况。本实践并不代表或取代必须根据其判断给定专业服务是否充分的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本实践。 标题中的“标准”一词仅表示该实践已通过ASTM共识程序获得批准。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本规程旨在收集皮肤污染样本，用于估计皮肤接触金属和类金属的情况。本规程旨在用于收集对危害评估、风险评估或其他目的感兴趣的皮肤样本。本规程旨在提供一种标准化方法，用于估计通过皮肤接触空气或表面污染物（或两者）可能暴露于身体部位的暴露。 5.2 本规程中描述的技术可能无法准确反映金属或类金属残留物通过皮肤接触的可转移性或生物利用度。 5.3 有关皮肤暴露测量原理和方法的更多信息，请参阅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. ====== Significance And Use ====== 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.
