3. Fire protection other than that specified in
this section for equivalent masonry, concrete or
plaster fire protection on outside surfaces of

when tested in accordance with ASTM G 21. Material shall have a flame
spread of 25 or less and a smoke developed rating of 50 or less when tested
in accordance with ASTM E 84.

NOTE: For Navy projects use the table in NAVFAC's
guide specification, since the numbers in the table
were provided by the manufacturer's when the spec
was developed. Otherwise, include the same numbers
into these paragraphs. The wording in the
