1、Designation: D 6757 07Standard Specification forUnderlayment Felt Containing Inorganic Fibers Used inSteep-Slope Roofing1This standard is issued under the fixed designation D 6757; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th

2、e 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 (1) inorganic fiber-reinforcedorganic felt underlayment and (2) inorganic fiber-b

3、ased felt foruse as underlayment with steep-slope roofing products. Theintent of this specification is to provide criteria for producingand evaluating underlayments with a significantly reducedtendency to wrinkle before or after the installation of steeproofing products.1.2 The values stated in SI u

4、nits are to be regarded as thestandard. The values in parentheses are for information only.1.3 The following safety hazards caveat pertains only to thetest method portion, Section 8, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with it
