9.4.2 If a standard or specification for use between two or three parties requires a defined property level after a specific time or radiant exposure in an exposure test conducted according to this practice, base the specified property level on at least two independent experiments run in each laboratory to determine the reproducibility for the exposure and property measurement process. The reproducibility of the exposure/property measurement process is then used to determine the maximum or minimum level of property after the exposure that is mutually agreeable to all parties.
在依据此规程作曝露测试时,如果一个用于两方或者三方的标准或者规格要求一个在一个特定时间或者发光曝露之后明确的属性级,基于此在至少两个独立的实验所测定的特定的属性级,来测定此曝露和属性测量程序的再现性。然后此曝露和属性测量程序的再现性就可以用于测定相关各方同意的曝露以后属性的最高或者最低级别
9.4.3 When reproducibility in results from an exposure test conducted according to this practice has not been established through round-robin testing, specify performance requirements for materials in terms of comparison (ranked) to a control material. All specimens shall be exposed simultaneously in the same device. All concerned parties must agree on the specific control material used.
如果根据此规程所作出的曝露结果的再现性还没有通过循环测试来确定,要根据与对照材料的对比为材料指定一个性能要求。所有的样本都应该同时在相同的设备上尚曝露
9.4.3.1 Conduct analysis of variance to determine whether the differences between test materials and any control materials used are statistically significant. Expose replicates of the test specimen and the control specimen so that statistically significant performance differences can be determined.
做方差试验来检测试样和所使用的任何对照材料之间的区别在统计上是否明显,曝露试样和对照样本的副本来检测统计上明显的性能差异。
