1.1本指南涵盖了关于可变性来源和减少暴露试验的策略的信息，以及在外部和实验室加速暴露试验的设计、执行和数据分析中考虑可变性的信息。 1.2以英寸-磅或国际单位制表示的数值应单独视为标准。括号中给出的值仅供参考。 1.3本标准无意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 guide covers information on sources of variability and strategies for its reduction in exposure testing, and for taking variability into consideration in the design, execution, and data analysis of both exterior and laboratory accelerated exposure tests. 1.2 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only. 1.3 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.
