(Test Method)Standard Test Method for Fastener Rupture and Tear Resistance of Roofing and Waterproofing Sheets, Roll Roofing, and Shingles
Standard Test Method for Fastener Rupture and Tear Resistance of Roofing and Waterproofing Sheets, Roll Roofing, and Shingles
SIGNIFICANCE AND USE
4.1 Test values for the resistance of specific ply sheets, roll roofing, or shingles to selected fastener pull-through may assist in the determination of appropriate fastener spacing. The relative behavior of different fasteners and fasteners with and without caps may be evaluated.
4.2 Laboratory data will not permit prediction of field performance, particularly long-term performance, and if all test conditions are not the same, data may not be comparable.
SCOPE
1.1 This test method covers the determination of the force needed to pull a fastener through any type of roofing or waterproofing ply sheet, roll roofing, or shingle, or to cause fastener failure under specified laboratory conditions.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently 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 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

nominal dimensions of 102 by 51 mm (4[4 by 2 in.)in.] and 4.8-mm ([ ⁄16-in.)-in.] wall thickness, fabricated as shown in Fig. 1.
5.4 Wood Nailers, 33 by 89 − 13, + 1 by 102 mm (1.5[1.5 by 3.5 − 0.5, + 0.05 by 4 in.)in.] (nominal 2 by 4 in. lumber cut to
4 in. length is appropriate). Thirty nailers are required per sample.
NOTE 1—The wood nailers must hold the fastener securely and remain secure in the nailer holding jig during the test. The 89-mm (3.5-in.)[3.5-in.]
dimension is critical for the nailer to be secure in the jig; the other dimensions are not critical and may be varied so long as the nailer works. If preferred,
the operator may use continuous lengths of nailer stock up to 1 m (40 in.)[40 in.] long for multiple specimens as opposed to cutting separate nailers for
each specimen.
6. Sampling and Test Specimens
6.1 Cut 15 MD specimens, 175 by 100 mm (7[7 by 4 in.),in.], in the machine direction (MD) and another 15 XMD specimens
in the cross-machine direction (XMD) from a representative portion of the sheet to be tested. If no particular sheet is specified,
use Type 1 asphalt-saturated organic felt conforming to the requirements prescribed in Specification D226.
6.2 Thirty fasteners of the type to be tested are required. If no particular fastener is specified, use galvanized roofing nails with

a 38-mm (1[1 ⁄2 in.)in.] long 3.6-mm (0.1205-in.)[0.1205-in.] diameter straight shank and a 9.5-mm ([ ⁄8-in.)-in.] diameter head.
7. Conditioning
7.1 Condition all specimens and nailers at 20 to 25°C (68[68 to 77°F)77°F] and at 50 6 5 % relative humidity for a minimum
of 16 h prior to testing.
8. Procedure
8.1 Position each sheet specimen on a broad side of a nailer so that a 100-mm (4-in.)[4-in.] side of the sheet specimen is parallel
to and 20 6 2 mm (0.75[0.75 6 0.125 in.)in.] from a 100-mm (4-in.)[4-in.] side of the nailer as shown in Fig. 2. Fasten each
specimen to its nailer with a fastener centered in the nailer and centered with respect to the sheet width.
NOTE 2—If continuous lengths of nailers up to 1 m (40 in.)[40 in.] long are used, the specimens should be positioned side by side on a broad side of
a nailer with a 100-mm (4-in.)[4-in.] side 20 6 2 mm (0.75[0.75 6 0.125 in.)in.] from a long side of the nailer. For each specimen the fastener should
be centered with respect to the nailer width and sample width. See Fig. 3.
