' l4 f+ b- ?3 t4 I3 \Question:
& m1 e# I3 h+ p( l! i3 a. pIn 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?
