HARD BODY IMPACT TESTA1.1 ScopeA1.1.1 The hard body impact test measures resistance topenetration of a wall panel when impacted by a rigid body.Failure in the hard body impact test

30、is achieved when theimpacting head completely penetrates through the test panel, orthe depth of the indentation exceeds the thickness of theproduct being tested when measured from the face sidefollowing impact, or both.A1.2 Summary of Test MethodA1.2.1 A nominal 2 by 2 ft 610 by 610 mm specimen ismo

Theimpactor is dropped from a fixed height to impart specificdesign energy to the wall specimen. Weights are progressivelyadded to the impactor to increase the design impact energyuntil specimen f

32、ailure occurs. For each impact, a new testspecimen is used.A1.3 Significance and UseA1.3.1 The test method measures relative performance ofinterior wall panel materials. Although the test panel ismounted on framing and tested vertically as a wall assembly,the impact damage is normally limited to a s

41、 of the test specimenis in the same plane as the face of the impact head.A1.7.1.1 A new test wall assembly shall be used for eachimpact.A1.7.2 The ramming arm is raised to the top or the arc andsecured with a pin.A1.7.3 The pin is removed, allowing the arm to swing freelyand strike the test specimen

42、.A1.7.4 A new test wall assembly is mounted to the appara-tus and the weight on the impactor is increased by adding 2.50lb 1.10 kg to the weight bar and the test repeated.A1.7.5 The test shall be performed by incrementally in-creasing the barbell free weights on the impactor until a failureimpact en

43、ergy is achieved.A1.7.5.1 The failure impact energy is defined as the mini-mum energy required for the impactor to penetrate through theface of the panel into the stud cavity, or when the depth of theindentation exceeds the thickness of the product being testedwhen measured from the face side.TABLE
