Fibre optic interconnecting devices and passive components - Report of round robin test results on SC plug style fixed attenuators1 Scope This part of IEC 62627 reports the measurement results of two round robin test programs each carried out on SC PC and SC APC plug style fixed attenuators. The work was initiated at Cenelec TC 86BXA in June 2003 in order to get a clear understanding on the accuracy and repeatability of the spectral attenuation loss measurements on fixed attenuators. Out of these results recommendations are made for attenuation tolerance values that can be used

Contents of BS EN 60335-2-98:

you can demonstrate the stability

does not specify acceptable risk levels and does not require that the manufacturer have a quality management system in place

The practical performance tests also have to be carried out successfully on complete apparatus where specified in this standard

BS EN 61508-6 contains information and guidelines on BS EN 61508-2 and BS EN 61508-3

BS 5381-8 applies mainly to the determination of the losses undergone throughout the distribution network and in the smoker’s pocket

The special shape of the Knoop indenter makes it possible to place indentations much closer together than with a square Vickers indentation
