Significance and Use
17、4.1 Each abuse/impact property of abuse resistant wall 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
18、the abuse-resistance classification of an abuse resistant 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 Classifica
19、tion5.1 Abuse resistant wall panels are classified into 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 requi
20、rements for each level are as shown in Tables 1-4.6. Test 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. Th
21、e abrasivemotion on the specimen creates measurable surface 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, co
22、nducted in accordance with Test Method D5420 (Gardner Impact), utilizes procedure GC,with a 58 in. -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
23、accordance with Method E695, is performed with the use of the standardleather bag filled with steel pellets to a weight of 60.0 lb 60.0 lb 27.2 kg and dropped through an angular distance until thespecimen is impacted.6.3.1 The specimen is mounted on nominal 2-by-4 wood studs 16 in. 400 mm o.c. Point
24、 of impact is midway between studsat the mid-height of the test panel.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 Surfa
25、ce damage and deformation are recorded following each impact, and the 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.
26、3 Following structural failure in the initial cavity, the procedure 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 ResistanceClassificationLevelAb

HARD BODY IMPACT TESTA1.1 ScopeA1.1.1 The ha
31、rd 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 being tested
32、 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 impart
33、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.TABLE 2 Performance RequirementsIndentation ResistanceClassificationLevelIndentationMaximumin. m
