1、Designation: D 6509 00Standard Specification forAtactic Polypropylene (APP) Modified Bituminous BaseSheet Materials Using Glass Fiber Reinforcements1This standard is issued under the fixed designation D 6509; the number immediately following the designation indicates the year oforiginal adoption or,
2、 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 specification covers prefabricated modified bitumi-nous sheet materials wi
3、th glass fiber reinforcement, which useatactic polypropylene (APP) as the primary modifier and whichare intended for use as a base sheet in the fabrication ofmultiple ply roofing and waterproofing membranes.1.2 This is a material specification only. Issues regarding thesuitability of specific roof c
4、onstructions or application tech-niques are beyond the scope of this specification.1.3 The specified tests and property limits used to charac-terize the sheet materials covered by this specification areintended to establish minimum properties. In-place roof systemdesign criteria, such as fire resist
5、ance, field strength, impact/puncture resistance, material compatibility, uplift resistance,the need for field applied coatings, and others, are factorsbeyond the scope of this material specification.1.4 The values stated in SI units are to be regarded as thestandard. Inch-pound units are given in p
6、arentheses for infor-mation only.1.5 The following precautionary statement pertains only tothe test method portion, Section 8, of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this stand
7、ard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

9、 the reinforcement isimpregnated and coated on both sides in an APP-modifiedbituminous coating. The APP-modified bituminous coatingmay be compounded with a mineral stabilizer.4.2 The base sheet may be surfaced with mineral matter toprevent sticking in the roll. The reverse side may be coveredwith a
10、thin polyolefin film or with other surfacing that will notinterfere with adhesion or bonding of the sheet during appli-cation.5. Physical Properties5.1 The sheet shall conform to the minimum physicalproperties described in Table 1.5.2 The finished product shall not crack or be so sticky as tocause t
11、earing or other material damage upon being unrolled atany product temperature between 4 and 60C (40 and140F).6. Dimensions, Mass, and Permissible Variations6.1 The finished product shall conform to the followingdimensions and variations:6.1.1 The width of the roll shall be as agreed upon betweenthe
12、purchaser and the supplier and shall not vary more than1%.6.1.2 The area of the roll shall be no less than as agreedupon between the purchaser and the supplier.6.1.3 The selvage width shall be within 6 mm (14 in.) of thenominal selvage width and shall be not less than 76 mm (3 in.)in width from the
13、edge of the sheet.6.2 The mass and thickness of the finished product shall beas prescribed in Table 2.7. Workmanship, Finish and Appearance7.1 The finished product shall be uniformly impregnatedand coated with atactic polypropylene (APP)-modified bitu-men. It shall be free of visible defects, such a
14、s holes, ragged oruntrue edges, breaks, cracks, tears, and protrusions.7.2 When unrolled on a smooth plane, the sheet shall bestraight and true so that the lap will mate with an adjacentsheet, within the tolerance for the lap without wrinkles,buckles, or fishmouths.1This specification is under the j

Materials shall be permitted to betested in 5.5C (10F) increments.8.3 Low Temperature UnrollingSample the material an
18、ddetermine the low temperature unrolling in accordance withTest Method D 5636 and as described herein. Report the lowesttest temperature at which none of the specimens show crackingor surface rupture. The temperature, at or below which theproduct must pass, is stated in Table 1.9. Inspection9.1 Insp

Rejection and Resubmittal10.1 Failure to ConformFailure to conform to any of therequireme
20、nts as stated in this specification constitutes groundsfor rejection.10.2 Rejection RedressThe supplier shall have the right toinspect the rejected materials. The supplier and the purchasershall agree to the quantity of rolls deemed unacceptable. Thesupplier shall then have the right to submit the s
21、ame number ofnew rolls as replacements.11. Packaging and Package Marking11.1 Unless otherwise agreed upon by the purchaser andsupplier, each product package shall be marked plainly with thesuppliers name, the product brand, the ASTM designation, thenet coverage, and the type of bitumen if not eviden
22、t in the labelname of the product.11.2 The rolls shall be wrapped or banded securely in amanner that completely encircles the roll and will preventslipping or unrolling.11.3 No roll shall contain more than two pieces and no morethan 3 % of the rolls in any lot shall contain two pieces. If a rollcont
