Standard Practice for Collection of Fungal Material From Surfaces by Tape Lift 用胶带提升法从表面收集真菌材料的标准实施规程
发布日期: 2021-09-01
1.1 本规程描述了使用胶带提升机收集表面样品并将其运送至实验室的协议。 1.2 本规程的目的是帮助现场调查人员区分真菌材料和非真菌材料,如磨损、烟尘沉积物、污渍、颜料、灰尘、风化、粘合剂和水渍。 1.3 本规程收集的样品适用于直接显微镜的定性或定量分析。 1.4 本规程不涉及建筑物居住者暴露或居住者健康风险。 1.5 这种做法不涉及制定正式假设或建立抽样目标。 1.6 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。 1.7 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。 1.8 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====== 4.1 本规程定义了使用透明单面粘合剂收集介质(通常为胶带(也称为胶带提升))收集表面材料的一致程序。 4.2 根据本规程收集的胶带提升样品旨在用于评估表面某个特定位置的材料中的真菌含量。 4.3 从关注点收集的胶带提升样品可用于定性分析或量化每个样品或单位面积的真菌材料。注意,取样表面的材料回收效率未知,可能是定量分析的不确定性来源。 4.4 根据本规程采集的胶带提升样品可通过直接显微镜进行分析。 4.5 这种做法可能有助于在室内空气质量调查期间补充霉菌采样的一致性。
1.1 This practice describes the protocols for collection of surface samples using tape lifts and their delivery to the laboratory. 1.2 The purpose of this practice is to support the field investigator in differentiating fungal materials from non-fungal material such as scuffs, soot deposits, stains, pigments, dust, efflorescence, adhesives, and water stains. 1.3 The samples collected by this practice are appropriate for either qualitative or quantitative analysis by direct microscopy. 1.4 This practice does not address building occupant exposures, or occupant health risks. 1.5 This practice does not address the development of a formal hypothesis or the establishment of sampling objectives. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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 ====== 4.1 This practice defines a consistent procedure for collecting surface material using clear, transparent, single sided adhesive collection medium, typically tape (also known as tape lift). 4.2 A tape lift sample collected according to this practice is intended to be used to assess the material present at one specific location on a surface for fungal content. 4.3 A tape lift sample collected from a point of interest can be used for qualitative analysis or to quantify fungal material per sample or per unit area. Note that the recovery efficiency of material from the surface sampled is unknown and a likely source of uncertainty for quantitative analyses. 4.4 A tape lift sample collected according to this practice can be analyzed by direct microscopy. 4.5 This practice may help supplement consistency in mold sampling during an indoor air quality investigation.
