范围:IEC 60793的本部分提供了光纤样品在动态载荷下的抗拉强度值。该方法测试未捆扎和未捆扎玻璃光纤的各个长度。纤维截面在整个纤维长度和横截面上均匀的受控增加应力或应变下断裂。应力或应变以名义上恒定的速率增加，直到发生断裂。 给定纤维的抗拉强度值分布在很大程度上取决于样品长度、加载速度和环境条件。该试验可用于需要纤维强度统计数据的检验。结果通过统计质量控制分布报告。通常情况下，试验在样品温度和湿度调节后进行。然而，在某些情况下，测量环境温度和湿度条件下的值就足够了。 本方法适用于A1、A2和A3类以及B和C类光纤。 本文件的目的是建立机械特性的统一要求:抗拉强度。交叉引用:EN 60793-1-20IEC 60793-1-20IEC TR 61649:2008IEC 60793-2-10:2017IEC 60793-2-60:2008IEC 60793-1-21:2001IEC 60793-2-40:2015IEC 60793-2-50:2015IEC TR 62048:2014IEC 60793-2-20:2015购买本文件时可提供的所有当前修改件均包括在购买时。

Scope: This part of IEC 60793 provides values of the tensile strength under dynamic loading of optical fibre samples. The method tests individual lengths of uncabled and unbundled glass optical fibre. Sections of fibre are broken with controlled increasing stress or strain that is uniform over the entire fibre length and cross section. The stress or strain is increased at a nominally constant rate until breakage occurs. The distribution of the tensile strength values of a given fibre strongly depends on the sample length, loading velocity and environmental conditions. The test can be used for inspection where statistical data on fibre strength is required. Results are reported by means of statistical quality control distribution. Normally, the test is carried out after temperature and humidity conditioning of the sample. However, in some cases, it can be sufficient to measure the values at ambient temperature and humidity conditions. This method is applicable to categories A1, A2, and A3, and classes B and C optical fibres. The object of this document is to establish uniform requirements for the mechanical characteristic: tensile strength.Cross References:EN 60793-1-20IEC 60793-1-20IEC TR 61649:2008IEC 60793-2-10:2017IEC 60793-2-60:2008IEC 60793-1-21:2001IEC 60793-2-40:2015IEC 60793-2-50:2015IEC 60793-2-30:2015IEC TR 62048:2014IEC 60793-2-20:2015All current amendments available at time of purchase are included with the purchase of this document.
