Jim, Are we talking about a mechanical enclosure or electrical enclosure? Surely, not a fire enclosure. Refet to 4.7.3.3 which discusses "Materials for Components and Other Parts Outside Fire Enclosures". The combination plastic/cloth would have to meet HB or HBF, however, there are many exceptions in this clause which I am sure you will be able to meet without having to subject the plastic/cloth combination for additional flame testing. Best Regards, Peter

There is no external surface of combustible material having an exposed area of greater than 0,9 m2 (10 sq ft) or a single dimension greater than 1,80 m (6ft) in compliance with Annex NAE 4.7.3.1 It is being proposed that cloth be added onto or over the exterior surface to address some marketing needs. Is anyone aware of flammability or other conditions put on cloth coverings for products?
