英语翻译
9.1 Precision—In an interlaboratory test of this test methodwith three different films on panels,ten laboratories and operators,and repeated by switching leads and panels between laboratories,the within-laboratory standard deviation found to be 0.52 and the between-laboratory standard deviation was found to be 0.61.Based on these standard deviations,the following criteria should be used for judging the acceptability of results at a 95 % confidence level:
9.1.1 Repeatability—Two results obtained by two operators within a laboratory using the same pencils and panels should be
considered suspect if they differ by more than one pencil unit
on the scale described in 5.1.
9.1.2 Reproducibility—Two results,each the mean of at least two determinations,obtained by operators in different laboratories using the same pencils and panels or different pencils with the same panels should be considered suspect if they differ by more than one pencil unit on the scale described in 5.1.
9.1.3 Bias—Since there is no acceptable material suitable for determining the bias for the procedure in this test method for measuring pencil hardness,bias cannot be determined.

9.1 精密-在一个这一个测试的实验室之间的测试 methodwith 在嵌板、十间实验室和操作员上的三个不同的电影中,而且藉由转变领引和在实验室之间的嵌板重复,那在-里面发现的实验室标准偏离是 0.52 和实验室间的标准偏离被发现了是 0.61.基于这些标准的偏离,下列的标准应该作为一个 95% 信心水平判断结果的可接受:
9.1.1 重复性-二结果获得二个一间实验室里面的操作员使用相同的铅笔而且嵌板应该是考虑过的嫌疑犯如果他们根据多于一支铅笔单位不一致在 5.1 年被描述的刻度上.
9.1.2 重制度-二如果他们在 5.1 年被描述的刻度上根据多于一支铅笔单位不一致,结果,至少二决心的每低劣者,在使用相同的铅笔的不同的实验室中由操作员获得,而且嵌板或者与相同的嵌板的不同的铅笔应该是考虑过的嫌疑犯.
9.1.3 偏见-自从没有以后可接受的物质适当的为为程序在这一个测试测量的方法铅笔坚硬方面决定偏见,偏见不能够被决定.
