BS EN 60793-1-21:2002

This standard BS EN 60793-1-21:2002 Optical fibres. Measurement methods and test procedures is classified in these ICS categories:

• 33.180.10 Fibres and cables

Gives four methods for measuring the coating geometry of optical fibres. The following parameters are measured: coating diameter, coating non-circularity, coating-cladding concentricity error. The methods are conducted off-line during inspection. They are not suitable for on-line, in-process measurements.
