9、 test method, refer to Terminology D1079.4. Summary of Test Method4.1 The capability of asphalt-based roofing or waterproofing materials to seal around a penetrating fastener and prevent thepassage of liquid water at the fastener/material interface is determined by penetrating the material with a fa
10、stener, erecting a watercolumn over that penetration, and monitoring the assembly for water passage for a period of time.4.2 The test method includes protocols that establish levels for the test method parameters. The protocol used to evaluate amaterial is designated in a standard specification for

16、C700, West Conshohocken, PA 19428-2959. United States1as a purposeful and planned part of the construction process, it is reasonable to expect that materials designed to limit migrationof liquid water at the interface between the penetrating fastener and the material will do so. This qualitative tes
17、t method providesa means to evaluate the ability of a material to limit water migration at fastener penetrations when tested under defined conditions.6. Apparatus6.1 Specimen RollerA roller having a mass of 11.8 kg 26 lb 60.5 %, diameter of 125 mm 5 in. 65 %, and width of 125mm 5 in. 65 %.6.2 Water
18、Column ContainerA4A 4 L 1 gal can with the bottom cut out.6.3 SealantAny commercially-available sealant suitable for sealing the water column container to the roofing or waterproof-ing material that will not adversely affect the roofing or waterproofing material.6.4 FastenerThe item that penetrates
19、the test specimen. Use one fastener for each test specimen. Refer to Table 1.6.5 SubstrateThe material to which the test specimen is attached prior to penetration with the fastener. One piece 255 by 255mm 10 by 10 in. 65 % is required for each test specimen. Refer to Table 1.6.6 Intervening Material
20、A material placed between the test specimen and the fastener. Refer to Table 1.7. Sampling7.1 From each lot of roofing or waterproofing material, select sample rolls in accordance with Test Methods D5147D5147/D5147M.7.2 The rolls so selected shall constitute the representative sample used for all te
21、sts pertaining to the lot of material beingexamined.8. Test Specimens8.1 Each test specimen shall consist of one piece of roofing or waterproofing material, 255 by 255 mm 10 by 10 in. 65 %65 % in size, selected at random from a sample roll.8.2 At least one test specimen shall be selected from each s
22、ample roll.8.3 Condition test specimens at 23 6 2C 73.4 6 3.6F and 50 6 10 % relative humidity for at least four hours prior to testassembly preparation.9. Test Assembly Preparation9.1 Select a protocol from Table 1 for the material to be evaluated (see Appendix X1) or use the protocol designated by
23、 thestandard specification for the material. Specify the number of specimens to be selected from each sample roll.9.2 Prepare one test assembly for each test specimen, assembling the materials in accordance with these instructions and asillustrated in Fig. 1. Use the substrate, intervening material,
24、 fastener, and fastener driving method specified by the selected protocol(see Table 1).9.3 Apply the test specimen to the substrate specified in the selected protocol (see Table 1, Substrate) as follows:9.3.1 Self-adhesive materialsPeel the release paper or film off the roofing or waterproofing spec
25、imen and lightly place thespecimen on the substrate, centering the specimen on the substrate with the edges of the specimen and substrate aligned. Pressdown the edges of the specimen just hard enough to keep the edges from lifting. Roll the specimen to promote adhesion to thesubstrate using the spec
26、imen roller, completing a total of three back-and-forth cycles. Each cycle shall be completed in 4 to 6 s.9.3.2 Non-self-adhesive materialsPlace the specimen on the substrate, centering the specimen on the substrate with the edgesof the specimen and substrate aligned.9.4 Place two pieces of lumber,
27、oriented parallel to each other and spaced 50 6 10 mm 2 6 0.5 in. apart, underneath thesubstrate for support.9.5 Place the intervening material specified in the selected protocol (see Table 1, Intervening Material) on top of the testspecimen, centering it in both directions.9.6 Drive one fastener sp
28、ecified in the selected protocol (see Table 1, Fastener) through the intervening material (if present),test specimen, and substrate near the center of the specimen in the area between the two pieces of supporting lumber in the mannerspecified in the selected protocol (see Table 1, Fastener Driving M
29、ethod).9.7 Place the water column container on the specimen, centered over the fastener. Apply a 6 to 10-mm 0.25 to 0.375-in. beadof sealant completely around the outside rim of the water column container to bond it to the specimen. Allow a minimum of 2 hfor the sealant to set, then apply another be
30、ad around the inside rim of the water column container.9.8 Maintain the test assembly at 23 6 2C 73.4 6 3.6F and 50 6 10 % 10 % relative humidity for 24 hours to allow thesealant to cure.D7349/D7349M 152TABLE 1 ProtocolsPROTOCOL 1Substrate APA Rated Sheathing, 3216, Exposure 1 plywood,12 mm 1532 in.
