SUMMARY OF TOPICS

The following topics for the Standard for Test Methods for Fire Tests of Roof Coverings, UL 790, are being recirculated:

1. Revisions to the Scope to clarify that the standard covers relative fire characteristics, so as not to be confused with the term "fire resistance".

2. Revisions to several sections covering a) the required number of assemblies to be tested and b) that the requirements shall be applied in sequence.

4. Addition of a new requirement covering conditioning of the self-sealing shingle test decks at a temperature of 135 to 140�F (57 to 60�C) for a continuous period of 16 hours.

7. Revisions of the burning-brand test covering the placement of the Class A and Class B brands.
