Re: Criteria for UL V0 plastic enclosure

2002-04-15 Thread Rich Nute




Hi Scott:


   In the case of LPS, wouldn't the plastic enclosure still be considered 
 decorative
   plastic outside a fire enclosure and required to meet HB flame class (per 
 UL
   60950, 4.7.3.3)?

Yes.

Virtually all plastic materials meet the HB flame class,
hence my comment that he may use any plastic.


Best regards,
Rich
