The test sample is to be subiected during the test to a static loadlocated at the geometnic center and rotated to any position determined to be most critical for penetration on the upper surace of that part of the sample exposed to the flame. See Fiqure 10.3. The static load is tobe gently lowered onto the test sample 3 to 5 seconds after the test sample is in place.
