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.
30、Failure in the hard body impact test 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
31、2 by 2 ft 610 by 610 mm specimen ismounted to the apparatus frame. A ramming arm impactorstrikes the wall specimen while swinging in an arc. Theimpactor is dropped from a fixed height to impart specificdesign energy to the wall specimen. Weights are progressivelyadded to the impactor to increase the
32、 design impact energyuntil specimen failure 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 imp
33、act damage is normally limited to a small area.A1.4 ApparatusA1.4.1 The apparatus consists of a rigid frame with aramming arm pinned to swing in an arc. See Figs. A1.1 andA1.2. The frame is constructed of 14 ga, 158 by 158 in. 41.3by 41.3 mm B-Line B24 Regular Framing Channels.A1.4.1.1 The dimension
34、s and details of the ramming armimpactor are shown in Fig. A1.3. The ramming arm impactorconsists of a cylindrical steel impact head (made by milling around steel bar), a structural steel tubing with square cross-section, two square steel plates (front and rear end plates of thestructural steel tubi
35、ng), a steel plate pivot arm, a round steel bar(to add weights), and a rectangular steel plate attached to thebottom of the structural steel tubing. The total weight of thecomponents of the ramming arm impactor is 20.0 lb 9.07 kg6 0.5 %, as shown in Table A1.1. The center of mass of theramming arm i
36、mpactor coincides with the location of the steelround bar (that is, the weight bar). Additional weights areattached to the weight bar to increase the impacting energy.A1.4.1.2 The ramming arm impactor shall have a suitablemechanism to secure it at the top of the swing. An example ofsuch a mechanism
37、is a small eyebolt attached to the back of theimpactor. When released from the top of the swing, the dropheight of the center of mass of the ramming arm impactor shallbe 12.0 in. 305 mm.A1.4.1.3 The ramming arm is located such that the face ofthe impactor head, when hanging free at the bottom of the
38、 arc,is in the same plane as the surface of the test specimen so that,when dropped, the impactor head strikes the surface of thespecimen at the bottom of the arc.A1.5 Test SpecimenA1.5.1 The test wall assembly shall be constructed byattachinga2by2ft610 by 610 mm specimen of the interiorwall panel ma
39、terial to a frame of 358 in. 92 mm deep 20 gasteel studs with Type S-12 bugle head screws spaced 8 in. 200mm o.c. as shown in Fig. A1.4. The length of the screws shallbe 114 in. 32 mm for panels up to58 in. 15.9 mm inthickness. For panels with thickness greater than58 in. 15.9mm, the length of the s
40、crews shall be at least58 in. 16 mmlonger than the panel thickness.A1.6 Preparation of ApparatusA1.6.1 The apparatus shall be securely anchored to a levelfloor to prevent sliding or rocking of the apparatus duringimpact.A1.7 ProcedureA1.7.1 The test wall assembly shall be securely clamped tothe face
41、 of the apparatus so that the surface 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 swi
42、ng freelyand strike the test specimen.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
43、the impactor until a failureimpact energy 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 testedwh
