Significance and Use4.1 Each abuse/impact property of abuse resistant wall
17、panels is divided into three classification 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 resista
18、nt wall panel. Each classificationlevel 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
19、 one of three levels of abuse resistance 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 through 6.4.5.2 Minimum requirements for each level are as shown in Tables 1-4.6. Te
20、st Methods6.1 Surface Abrasion TestThis test is conducted in accordance with Test Method D4977 using a total load of 25.0 lb. Thespecimen is conditioned to constant weight at 70F and 50 % relative humidity and subjected to 50 abrasion cycles. The abrasivemotion on the specimen creates measurable sur
21、face wear or indentation which is measured to determine the level of surfaceabrasion resistance.NOTE 1It is especially important to prepare the apparatus and condition the brush as specified in Test Method D4977.6.2 Indentation TestThis test, conducted in accordance with Test Method D5420 (Gardner I
22、mpact), utilizes procedure GC,with a 58 in. hemispherical head and a 72 in.-lb. 12.6 J impact energy. The depth of the indentation is measured to determinethe level of indentation resistance.6.3 Soft Body Impact TestThis test, conducted in accordance with Method E695, is performed with the use of th
23、e standardleather bag filled with steel pellets to a weight of 60.0 lb 27.2 kg and dropped through an angular distance until the specimenis impacted.6.3.1 The specimen is mounted on nominal 2-by-4 wood studs 16 in. 400 mm o.c. Point of impact is midway between studsat the mid-height of the test pane
24、l.6.3.2 A single specimen is repeatedly impacted at a single point of impact in one cavity with the drop height being increasedby 6 in. with each successive drop until structural failure as defined in 3.2.2 is achieved.6.3.2.1 Surface damage and deformation are recorded following each impact, and th
25、e level of impact energy applied iscalculated. The residual deflection shall be measured from the face side of the panel.NOTE 2Surface damage and deformation, which do not constitute structural failure, may compound the results.6.3.3 Following structural failure in the initial cavity, the procedure
26、described in 6.3.2 is repeated on the next cavity, beginningwith a drop height of 6 in. higher than the drop height causing structural failure in 6.3.2.TABLE 1 Performance RequirementsSurface Abrasion ResistanceClassificationLevelAbraded DepthMaximumin. mm1 0.126 3.22 0.059 1.53 0.010 0.3C1629/C1629

HARD BODY IMPACT TESTA1.1 ScopeA1.1.1 The hard body impact test measures resistance to penetration of a wall pane
31、l 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 being tested when measured from the face side following impact, or both.A1.2 Summ
32、ary 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 impart specific design energy to the wallspecimen. Weights are progressively
33、 added to the impactor to increase the design impact energy until specimen failure occurs. Foreach impact, a new test specimen is used.TABLE 2 Performance RequirementsIndentation ResistanceClassificationLevelIndentationMaximumin. mm1 0.150 3.82 0.100 2.53 0.050 1.3TABLE 3 Performance RequirementsSof

35、interior 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.A1.4 ApparatusA1.4.1 The apparatus consists of a rigid frame with a ramming arm pinned to swing in an arc. See Figs.A1.1 and A1.
36、2. The frameis constructed of 14 ga, 1 58 by 1 58 in. 41.3 by 41.3 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 ramming arm impactor consistsof a cylindrical steel impact head (made by milling a round steel bar), a
37、 structural steel tubing with square cross-section, two squaresteel plates (front and rear end plates of the structural steel tubing), a steel plate pivot arm, a round steel bar (to add weights), anda rectangular steel plate attached to the bottom of the structural steel tubing. The total weight of
38、the components of the rammingarm impactor is 20.0 lb 9.07 kg 6 0.5 %, as shown in Table A1.1. The center of mass of the ramming arm impactor coincideswith the location of the steel round bar (that is, the weight bar). Additional weights are attached to the weight bar to increase theimpacting energy.
39、A1.4.1.2 The ramming arm impactor shall have a suitable mechanism to secure it at the top of the swing. An example of such amechanism is a small eyebolt attached to the back of the impactor. When released from the top of the swing, the drop height ofthe center of mass of the ramming arm impactor sha
40、ll be 12.0 in. 305 mm.A1.4.1.3 The ramming arm is located such that the face of the impactor head, when hanging free at the bottom of the arc, is inthe same plane as the surface of the test specimen so that, when dropped, the impactor head strikes the surface of the specimenat the bottom of the arc.
41、A1.5 Test SpecimenA1.5.1 The test wall assembly shall be constructed by attaching a 2 by 2 ft 610 by 610 mm specimen of the interior wall panelmaterial to a frame of 3 58 in. 92 mm deep 20 ga steel studs with Type S-12 bugle head screws spaced 8 in. 200 mm o.c. asshown in Fig. A1.4. The length of th
42、e screws shall be 1 14 in. 32 mm for panels up to 58 in. 15.9 mm in thickness. For panelswith thickness greater than 58 in. 15.9 mm, the length of the screws shall be at least 58 in. 16 mm longer than the panelthickness.A1.6 Preparation of ApparatusA1.6.1 The apparatus shall be securely anchored to
43、a level floor to prevent sliding or rocking of the apparatus during impact.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 Steel Pl
