7、 employed in conducting these tests. Fire testinginvolves hazardous materials, operations, and equipment. Thisstandard gives instructions on specimen preparation andmounting, but the fire-test-response method is given in TestMethod E84. See also Section 10.1.8 This standard does not purport to addre
