This Technical Report describes a method of type approval testing to define the ability of bunched cables to restrain flame propagation in defined conditions regardless of their application, i.e. power, telecommunications (including data transmission and optical fibre cables), etc.
Three categories are defined and distinguished by test duration, and the volume of non-metallic material of the sample under test (see table 1); they are not necessarily related to different safety levels in actual cable installations. Category A has two designations for the method of mounting.
