Conceptual problems with OSHA's use of an absolute standard have led to alternative methods of assessing exposures to toxic materials in the workplace. One of these methods employs a one-sided tolerance limit. This statistical approach is explored from three points of view--identifiability, sampling strategies and statistical power. In general, assessing risk in the work environment with tolerance limits is found to give inadequate answers in several important respects.
职业安全与健康管理局（OSHA）使用绝对标准存在概念性问题，这导致了评估工作场所有毒物质暴露的替代方法。其中一种方法采用单侧公差极限。从可识别性、抽样策略和统计功效三个角度探讨了这种统计方法。总体而言，发现用公差极限评估工作环境中的风险在几个重要方面给出的答案并不充分。
