Significance and Use4.1 Each abuse/impact property of abuse resistant wall panels is divided into three class

18、ification levels. The three levels ofclassification are: Level I, Level II, and Level III, with Level I representing the lowest rating for any given property. The testmethods specified are utilized to establish the abuse-resistance classification of an abuse resistant wall panel. Each classification

19、level requires a minimum overall specified performance. Any classified abuse resistant wall panel can be used at a classificationlevel which is rated lower than the highest level qualified.5. Basis of Classification5.1 Abuse resistant wall panels are classified into one of three levels of abuse resi

20、stance based on minimum performance whentested in accordance with test methods that evaluate surface abrasion, indentation, soft body impact, and hard body impact asspecified in 6.1 6.4.5.2 Minimum requirements for each level are as shown in Tables 1-4.6. Test Methods6.1 Surface Abrasion TestThis te

HARD BODY IMPACT TESTA1.1 ScopeA1.1.

37、1 The hard body impact test measures resistance to penetration of a wall panel when impacted by a rigid body. Failure inthe hard body impact test is achieved when the impacting head completely penetrates through the test panel, or the depth of theindentation exceeds the thickness of the product bein

38、g tested when measured from the face side following impact, or both.A1.2 Summary of Test MethodA1.2.1 A nominal 2 by 2 ft 610 by 610 mm specimen is mounted to the apparatus frame. A ramming arm impactor strikes thewall specimen while swinging in an arc. The impactor is dropped from a fixed height to

39、 impart specific design energy to the wallspecimen. Weights are progressively added to the impactor to increase the design impact energy until specimen failure occurs. Foreach impact, a new test specimen is used.A1.3 Significance and UseA1.3.1 The test method measures relative performance of interio

40、r wall panel materials. Although the test panel is mounted onframing and tested vertically as a wall assembly, the impact damage is normally limited to a small area. The method is not intendedto evaluate the performance of studs used in wall construction.A1.4 ApparatusA1.4.1 The apparatus consists o

41、f a rigid frame with a ramming arm pinned to swing in an arc. See Figs.A1.1 and A1.2. The frameis constructed of 14 ga, 1 58 by 1 58 in. 41 by 41 mm B-Line B24 Regular Framing Channels.A1.4.1.1 The dimensions and details of the ramming arm impactor are shown in Fig. A1.3.

The center of mass of the ramming arm impactor coincideswith the location of the steel round bar (that is, the weight bar). Add

44、itional weights are attached to the weight bar to increase theimpacting energy.TABLE A1.1 Weight (Mass) Schedule for the Components of theRamming Arm ImpactorComponent Weightlb, 0.5 % Masskg, 0.5 %Structural Steel Tubing (square cross-section)8.10 3.67Steel Plate Pivot Arm 1.10 0.50Front Square Stee
