12、urated with tap water and observed periodically for 30 minutes. Test Method: Cut a 457 mm x 457 mm sample and mount on a 12.7 mm plywood base measuring 610 mm x 610 mm. Staple perimeter at 51 mm intervals to assure sample lies flat. Saturate mounted sample with tap water and permit excess to flow off. Observe carpet for appearance changes periodically for 30 minutes. 3.15 FLAMMABILITY 101 mm/minute (FLTM BN 024-02) Tested as composite This cover material must always be bonded 100% to a substrate material to form a composite (localized or spotty adhesion is unacceptable).
