Standard Test Method for Direct Microscopy of Fungal Structures from Tape 胶带真菌结构直接显微镜检查的标准试验方法
发布日期: 2021-09-01
1.1 本试验方法使用光学显微镜检测、半定量和鉴定胶带提升制剂中的真菌结构。 1.2 本试验方法描述了胶带提升基质的制备技术、确认真菌结构存在的程序以及观察到的真菌结构的报告 1.3 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。 1.4 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。 1.5 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 该测试方法的意义在于,对用胶带从表面提起的可移动真菌结构的检测进行标准化分析,以提高实验室和分析员之间的一致性。 5.2 该测试方法旨在确保向最终用户提供一致的数据。 5.3 无论真菌是否会在培养基中生长,都会对其结构进行鉴定和半定量。 5.4 必须强调的是,本测试方法中的检测器是分析员,因此结果是主观的,取决于分析员的经验、培训、资格、视力和精神疲劳。 5.5 该测试方法可用于评估表面上真菌材料的存在和特性。
1.1 This test method uses optical microscopy for the detection, semi-quantification, and identification of fungal structures in tape lift preparations. 1.2 This test method describes the preparation techniques for tape-lift matrices, the procedure for confirming the presence of fungal structures, and the reporting of observed fungal structures 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. ====== Significance And Use ====== 5.1 The significance of this test method is to standardize the analysis of the detection of removable fungal structures lifted from a surface with tape to improve consistency between laboratories and analysts. 5.2 This test method is intended to ensure consistent data to the end user. 5.3 Fungal structures are identified and semi-quantified regardless of whether they would or would not grow in culture. 5.4 It must be emphasized that the detector in this test method is the analyst, and therefore results are subjective, depending on the experience, training, qualification, optical acuity, and mental fatigue of the analyst. 5.5 This test method can be used to assess the presence and characteristics of fungal material on a surface.
