IEC 60793-1-1-2017 pdf free.Optical fibres – Part 1-1: Measurement methods and test procedures – General and guidance.
This part of IEC 60793 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 afiliation to the IEC 60793-1 series.
In general, measurements and tests methods apply to all class A multimode fibres and class B and class C single-mode optical fibres covered by IEC 60793-2 (all parts) relating to product specifications, although there can be exceptions. Clause 1 of each part of the IEC 60793 series contains the scope for each particular attribute.

4 Rounding rules
All reported test results shall follow the conventional rounding rule1 of “rounding half away from zero”， when the results recorded display more than the significant number of digits required in the acceptance criteria. Only the first digit beyond the number of significant digits is used in determining the rounding. EXAMPLE 1 Against a requirement of 0,22 dB/km maximum attenuation, values up to 0,224 dB/km conform, whilst values of 0,225 dB/km and above are failures.IEC 60793-1-1 pdf download.
