Test Method 1 vs Test Method 2... What's the difference?
Test Method 1 applies to materials with a density less than or equal to 700/b/m². Items that fall within this category would be draperies/curtains or other fabrics used as window treatments. They are single layer fabrics. It is usually single-layer fabrics. The exception to this is when more than one layer is fastened together by sewing or other mechanical means.
Test Method 2 applies to plastic films, vinyl-coated fabric such as blackout linings, or lined curtains that have a vinyl coating. Decorative materials other than fabrics fall within this category. fabrics with or without reinforcement or a backing that is used as decoration inside a building must also pass Test 2. This also includes permanent enclosures for building under construction. Of course awnings, plastic tarps, tents, banners or membrane structures must meet the Test 2 requirements. These items cannot be tested to Test 1, only Test 2. If you aren't sure, please contact the NFPA or visit their website. The information is quite extensive and detailed. The purpose of this article was to give the reader a look into the fire certifications that apply to fire retardant/ flame retardancy of plastic sheeting.
