IEC 60793-1-1:2008 lists and gives guidance on the use of documents giving the uniform requirements for measuring and testing optical fibres, thereby assisting in the inspection of fibres and cables for commercial (mostly telecommunications) purposes. The individual measurement and test methods are contained in the different parts of the IEC 60793 series. They are identified as IEC 60793-1-X, where "X" is an assigned sub-part number, indicating its affiliation to IEC 60793-1. In general, measurements and tests methods apply to all class A multimode fibres and Class B single-mode optical fibres covered by the IEC 60793-2 series, although there may be exceptions. Clause 1 of each part of IEC 60793 contains the scope for each particular attribute. This third edition cancels and replaces the second edition published in 2002. The main changes with regard to the previous edition concern:
- re-wording of Clause 8: Categories of optical fibres;
- removal of Clause 10: Cross-reference of former test designations to current documents removal of the bibliography. Keywords: guidance on the use of documents giving the uniform requirements for measuring and testing optical fibres
