HARD BODY IMPACT TESTA1.1 ScopeA1.1.1 The hard body impact test measur
34、es resistance topenetration of a wall panel when impacted by a rigid body.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
35、sidefollowing impact, or both.A1.2 Summary of Test MethodA1.2.1 A nominal 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 wal
36、l specimen. Weights are progressivelyadded to the impactor to increase the 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 p
37、anel ismounted on framing and tested vertically as a wall assembly,the impact 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.
38、41 by 41 mm B-Line B24 Regular Framing Channels.A1.4.1.1 The dimensions 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 squa
39、re steel plates (front and rear end plates of thestructural steel tubing), 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
40、 0.5 %, as shown in Table A1.1. The center of mass of theramming arm impactor 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 suitablemechanis
41、m to secure it at the top of the swing. An example ofsuch a mechanism 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 tha
42、t the face ofthe impactor head, when hanging free at the bottom of the 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
43、 byattachinga2by2ft610 by 610 mm specimen of the interiorwall panel material to a frame of 358 in. 92 mm deep 20 gasteel studs with Type S-12 bugle head screws spaced 8 in.200 mm o.c. as shown in Fig. A1.4. The length of the screwsshall be 114 in. 32 mm for panels up to58 in. 15.9 mm inthickness. Fo
44、r panels with thickness greater than58 in.15.9 mm, the length of the screws shall be at least58 in.16 mm longer than the panel thickness.TABLE A1.1 Weight (Mass) Schedule for the Components of theRamming Arm ImpactorComponentWeightlb, 0.5 %Masskg, 0.5 %Structural Steel Tubing (square cross-section)8
