" N. v7 @, }+ z$ x$ zIn the photographs included below, a construction is shown with material not resistant to the glow wire test at 750ºC/850ºC marked PP and a terminal block mounted on 3 pins moulded on the material. In order to separate the connection area from the plastic part PP, a piece of a different material has been interposed. The pins fixing the terminal block are still made of material PP and are within a distance of less than 3 mm. Should material PP in this construction be tested with glow wire test at 750ºC/850ºC?

The material shall be tested if it is less 3 mm from the connection. The 3 mm distance has to be measured from the point of connection between the wire and the screw inside the terminal and not from other terminal part.5 O2 { p) {/ o# j) R! h
