1.1本规程描述了通过索氏提取法测定需要高清洁度的系统和部件（如氧气）中残留污染物的程序。 1.2本规程可用于从固体中提取非挥发性和半挥发性残留物，例如新的和用过的手套、新的和用过的湿巾、受污染的试样或对照试片、小件硬件、组件软件等，当与拟议的清洁材料（湿巾、手套等）一起使用时。 )，本规程可用于确定拟议溶剂提取污染物（增塑剂、残留洗涤剂、光亮剂等）并将其沉积在待清洁表面的潜力。 1.3本规程不适用于颗粒污染的评估。 1.4以国际单位制表示的数值为标准值。括号中的值仅供参考。 1.5 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和健康实践，并确定监管限制的适用性。

1.1 This practice describes a procedure for the determination of residual contamination in systems and components requiring a high level of cleanliness, such as oxygen, by Soxhlet extraction. 1.2 This practice may be used for extracting nonvolatile and semivolatile residues from solids such as new and used gloves, new and used wipes, contaminated test specimens or control coupons, small pieces of hardware, component softgoods, etc. When used with proposed cleaning materials (wipes, gloves, etc.), this practice may be used to determine the potential of the proposed solvent to extract contaminants (plasticizers, residual detergents, brighteners, etc.) and deposit them on the surface being cleaned. 1.3 This practice is not suitable for the evaluation of particulate contamination. 1.4 The values stated in SI units are standard. Values in parentheses are for information only. 1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
