Dear Group, I'm looking for some assistance on the interpretation of IEC/EN 61010-1, Clause 9.2.1 b) 3). This states that non-metallic materials used for enclosures shall have a flammability classification of F-V1, or better.
Does this requirement apply to plastics materials used to form small transparent windows in the sides of the metal enclosures? The type of window I am thinking of would be relatively small as compared with the size of the overall enclosure, be placed in front of an energy limited circuit, such as digital panel meter, and not be fulfilling any safety function. The metallic enclosure would include vents such as may be found on a PC base unit, or a bench-top power supply. Many thanks in anticipation of your help.
