Description
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.

ATTENTION: Belgian registered standards (NBN EN or NBN HD) are generally only available in English or French. Only the cover page is translated and the document itself is in English or in French.

Very important notice: 98% of the text of the NBN EN 55XXX, NBN EN 6XXXX comes from the IEC text which is NOT included. This text can be ordered here: IEC 60793-1-31:2019. For the series NBN EN 50XXX, the standards are however complete.
