2、n or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers a procedure for rapidly deforming by impact an EIFS

3、 for evaluating the effect of such deformation.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. The values given inparentheses are for information only.stated in each system may not be exact equivalents; therefore, each system shall be usedi

4、ndependently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate sa

United States16.1.4 Disregard all information concerning the panel support, magnifier, and pin-hole detector.7. Test Specimens7.1 The EIFS base coat, reinforcing m

15、esh, and finish coat shall be applied to 600 by 1200 mm (22 by 4 ft)ft sections of 25-mm(1-in)1-in thick insulation board, unless otherwise specified. Specimens shall be representative of those used in actualconstruction.7.2 The reinforcing mesh(es) or reinforced coating shall be continuous and have

16、 no laps or joints. The reinforcing mesh(es) shallnot be lapped onto the side or back of the specimen.8. Conditioning8.1 Allow the specimens to cure a minimum of 28 days at 22 6 3C (723C 72 6 5F)5F and 50 6 5%5 % relativehumidity. Conduct the test in the same environment or immediately on removal.9.

17、 Procedure9.1 Weigh the specimen and record the weight and the type and density of insulation board used in the specimen.9.2 Place the specimen on a smooth flat, rigid surface with the coated side up. Be sure the specimen is flat against the surface.No impact shall be made within 100 mm (4 in.)4 in.

18、 of the edges of the specimen nor within 100 mm (4 in.)4 in. from theprevious impact points. Raise the weight up the tube to the minimum value of the impact range (see 10.2) where it is expectedthat less than 40 percent 40 % of the ten tests will fail. Release the weight so that it drops on the test

19、 panel. Ten tests shall beperformed at this minimum value.9.3 Remove the specimen from the apparatus. With the naked eye and under normal lighting conditions, observe the impact areafor broken reinforcing mesh. If broken reinforcing mesh is observed in at least four out of the ten tests, repeat the

20、procedure atthe next higher impact range. If breakage is observed in more than four out of the ten tests, repeat the procedure at the next lowerrange. Perform each impact at different locations on the specimen as referenced in 9.2.9.4 For each drop height, tabulate the number of times the specimen d

21、isplayed broken reinforcing mesh.10. Interpretation of Results10.1 The EIFS tested shall be classified according to the impact range at which six or more impact tests did not display brokenreinforcing mesh.10.2 The following classifications and impact ranges have been established for Class PB EIFS:C
