1、Designation: D 4932 89 (Reapproved 2006)Standard Test Method forFastener Rupture and Tear Resistance of Roofing andWaterproofing Sheets, Roll Roofing, and Shingles1This standard is issued under the fixed designation D 4932; the number immediately following the designation indicates the year oforigin
2、al adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the forceneeded to

Ifno particular fastener is specified, use galvanized roofing nailswith a 38-mm
16、 (112 in.) long 3.6-mm (0.1205-in.) diameterstraight shank and a 9.5-mm (38-in.) diameter head.7. Conditioning7.1 Condition all specimens and nailers at 20 to 25C (68 to77F) and at 50 6 5 % relative humidity for a minimum of 16h prior to testing.8. Procedure8.1 Position each sheet specimen on a broa
17、d side of a nailerso that a 100-mm (4-in.) side of the sheet specimen is parallelto and 20 6 2 mm (0.75 6 0.125 in.) from a 100-mm (4-in.)side of the nailer as shown in Fig. 2. Fasten each specimen toits nailer with a fastener centered in the nailer and centeredwith respect to the sheet width.NOTE 2
