1、Designation: D7349/D7349M 10Standard Test Method forDetermining the Capability of Roofing and WaterproofingMaterials to Seal around Fasteners1This standard is issued under the fixed designation D7349/D7349M; the number immediately following the designation indicates theyear of original adoption or,
2、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 qualitative test method determines the capability ofasphalt-based roofing or
3、 waterproofing material to seal arounda fastener that penetrates the material and prevent transmissionof liquid water through the material at the penetration underdefined conditions.1.2 This test method is provided for adoption by ASTM orother consensus-based roofing and waterproofing productspecifi
4、cations as a standardized means to evaluate capability toseal around a fastener. Performance of this test method aftersubjecting the product to conditioning intended to simulateenvironmental stresses and strains is not prohibited.1.3 The text of this test method references notes andfootnotes which p

These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as requirements of the standard.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact
6、 equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the u
7、ser of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

9、 of Test Method4.1 The capability of asphalt-based roofing or waterproofingmaterials to seal around a penetrating fastener and prevent thepassage of liquid water at the fastener/material interface isdetermined by penetrating the material with a fastener, erectinga water column over that penetration,
10、 and monitoring theassembly for water passage for a period of time.4.2 The test method includes protocols that establish levelsfor the test method parameters. The protocol used to evaluatea material is designated in a standard specification for thematerial or by the user of this test method.5. Signi
11、ficance and Use5.1 In some situations, penetration through asphalt-basedroofing or waterproofing materials by fasteners is a requiredpart of the material installation process or occurs duringinstallation of other system components. When fasteners pen-etrate the material as a purposeful and planned p
12、art of theconstruction process, it is reasonable to expect that materialsdesigned to limit migration of liquid water at the interfacebetween the penetrating fastener and the material will do so.This qualitative test method provides a means to evaluate theability of a material to limit water migratio

Test Assembly Preparation9.1 Select a protocol from Table 1 for the material to beevaluated (see Appendix X1) or use the protocol designated bythe standard specification for the material. Specify the numberof specimens to
30、 be selected from each sample roll.9.2 Prepare one test assembly for each test specimen,assembling the materials in accordance with these instructionsand as illustrated in Fig. 1. Use the substrate, interveningmaterial, fastener, and fastener driving method specified by theselected protocol (see Tab
31、le 1).9.3 Apply the test specimen to the substrate specified in theselected protocol (see Table 1, Substrate) as follows:9.3.1 Self-adhesive materialsPeel the release paper orfilm off the roofing or waterproofing specimen and lightly placethe specimen on the substrate, centering the specimen on thes
32、ubstrate with the edges of the specimen and substrate aligned.Press down the edges of the specimen just hard enough to keepthe edges from lifting. Roll the specimen to promote adhesionto the substrate using the specimen roller, completing a total ofthree back-and-forth cycles. Each cycle shall be co

34、 2 6 0.5 in. apart, underneaththe substrate for support.9.5 Place the intervening material specified in the selectedprotocol (see Table 1, Intervening Material) on top of the testspecimen, centering it in both directions.9.6 Drive one fastener specified in the selected protocol(see Table 1, Fastener
35、) through the intervening material (ifpresent), test specimen, and substrate near the center of thespecimen in the area between the two pieces of supportinglumber in the manner specified in the selected protocol (seeTable 1, Fastener Driving Method).9.7 Place the water column container on the specim
36、en,centered over the fastener. Applya6to10-mm 0.25 to0.375-in. bead of sealant completely around the outside rim ofthe water column container to bond it to the specimen. Allowa minimum of 2 h for the sealant to set, then apply another beadaround the inside rim of the water column container.9.8 Maint
37、ain the test assembly at 23 6 2C 73.4 6 3.6Fand 50 6 10 % relative humidity for 24 hours to allow thesealant to cure.9.9 After the sealant has cured, condition the test assemblyas specified in the selected protocol (see Table 1, Test Assem-bly Conditioning).10. Procedure10.1 Conduct the test using t
38、he water depth, test tempera-ture, and test period specified in the selected protocol (seeTable 1).10.2 Place the test assembly atopa4L1-gal can fromwhich the lid has been removed.10.3 Fill the water column container to the depth specifiedin the selected protocol (see Table 1, Water Depth) withdeion
39、ized or distilled water.10.4 Place the test assembly and 4 L 1-gal bottom can ina temperature controlled chamber maintained at the tempera-ture specified by the selected protocol (see Table 1, TestTemperature).10.5 Maintain the test assembly at the test temperature forthe test period specified by th
40、e selected protocol (see Table 1,Test Period).10.6 At the conclusion of the test period, remove the testassembly from the 4 L 1-gal bottom can, carefully pour thewater from the water column container without splashing ontothe substrate, and blot the inside of the water column containerdry. Examine t
41、he assembly and note any water in the 4 L1-gal bottom can, on the shank of the fastener, or on theunderside of the substrate.10.7 Carefully remove the water column container from theroofing or waterproofing material. Peel the roofing or water-proofing material back to the fastener and inspect the un

EXPLANATORY INFORMATIONX1.1 This test method was developed to have broadapplicability for evaluating roofing and waterproofing productsemployed in a variety of end uses. Therefore, it does notcontain a single set of test parameters that apply t
47、o all producttypes. Instead, the method is designed to be referenced byproduct specifications, and allows the user or a referencingproduct specification to select a Protocol appropriate for use inevaluating the material of interest.X1.2 This test method is structured to accommodateaddition of new pr
48、otocols as needed to address new products ordifferent end uses. A protocol establishes test parameter levelsappropriate for the product and end use that is being evaluated.D7349/D7349M 104X1.3 This test method does not include accelerated weath-ering or simulated aging. Establishment of appropriate
49、“simu-lations” is left to the discretion of product specification taskgroups that choose to reference this test method for fastenerseal capability evaluation. Those task groups contain thenecessary product and application expertise to develop mean-ingful “simulation” methodology, and can choose to requirefastener seal capability testing before or after any relevant“simulation.”X2.
