- This tester is used to test the flammability of particular textile products such as night clothes with A-4 Method (Vertical Method) testing. The alternative Vertical Burner Method can also be used to measure the degree of spread of the burn and the after-flame. The flame height is set to 38 mm, and is placed 17 mm under the specimen clamped jig. After the center of the specimen is applied heat for 3 seconds, the length between the lower end and the torn end is measured.
