1. Scope
1.1 This specification covers factory-prepared reinforced bituminous sheet used in flashing. The bitumen used may be asphalt, coal-tar pitch, or polymer-modified bitumen. The reinforcement may include any one or a combination of organic (wood fiber), polyester, or glass fiber felts, woven fabrics, or thermoplastic films. Fine mineral powders, granules, or metal foils may be used as surfacing. 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 nonconformance with the standard. 1.3 The following precautionary statement pertains only to the test method portion, Section 7, of this specification: This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
5. Significance and Use
5.1 The criteria listed in this specification are based on round robin testing of materials that, if correctly installed, can be used as the primary material for flashing membranes. The manufacturer’s installation recommendations must be followed in every case. 5.2 Compliance with the criteria in this specification is believed to be necessary for satisfactory performance, but the linkage has not been established between performance and these criteria.
6. Physical Properties
6.1 Conform to criteria in Table 1.
7. Sampling and Test Methods
7.1 Comply with Test Methods D228/D228M for sampling. 7.2 Use the following test methods to test the samples: 7.2.1 Mass—See Test Methods D228/D228M. 7.2.2 Thickness—See Test Methods D751. 7.2.3 Load-Strain Properties—See Practice D2523/ D2523M except as noted herein: test five 25 by 150 mm [1 by 6 in.] strips in both the length and width of the roll, using a 100 mm [4 in.] jaw gap, and separate the jaws at 0.85 mm/s [2 in. ⁄min.]. Record maximum load and elongation at maxi- mum load. 7.2.4 Impact Resistance—See Test Method D3746/ D3746M, test with each sample loose laid on a nominal 25 mm [1 in.] thick fiberboard insulation. 7.2.5 Tear Strength—See Test Method D5601. 7.2.6 Flexibility—See Test Method D5683/D5683M. 7.2.7 Heat Conditioning—Mass, thickness, load, and elon- gation after 35 6 0.25 consecutive days ofheat conditioning in a forced-draft oven at 70 6 3 °C [158 6 5 °F]. See Practice D5869/D5869M.
9. Inspection
9.1 Inspection—Inspection shall be in accordance with the requirements of this specification. 9.2 Inspection Alternatives—Alternative inspection require- ments shall be determined by and as agreed upon between the purchaser and supplier.
10. Rejection and Resubmittal
10.1 Failure to Conform—Failure to conform to any of the requirements as stated in this specification constitutes grounds for rejection. 10.2 Rejection Redress—The supplier shall have the right to inspect the rejected materials. The supplier and the purchaser shall agree to the quantity of rolls deemed unacceptable. The supplier shall then have the right to submit the same number of new rolls as replacement.
11. Packaging and Package Marking
11.1 The rolls shall be securely wrapped or banded in a substantial grade of paper that completely encircles the face of the roll in a manner that will prevent slipping. 11.2 No roll shall contain more than two pieces, and no more than 3 % of the rolls in any lot shall contain two pieces. 11.3 Unless otherwise specified, each package shall be plainly marked with the manufacturer’s name, brand name, ASTM designation, and the appropriate application technique.
