1、Designation: D 6221 00 (Reapproved 2006)Standard Specification forReinforced Bituminous Flashing Sheets for Roofing andWaterproofing1This standard is issued under the fixed designation D 6221; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、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 factory prepared reinforcedbituminous sheet used in flashing. The bit
3、umen used may beasphalt, coal-tar pitch, or polymer modified bitumen. Thereinforcement may include any one or a combination oforganic (wood fiber), polyester, or glass fiber felts, wovenfabrics, or thermoplastic films. Fine mineral powders, granules,or metal foils may be used as surfacing.1.2 The va
4、lues stated in SI units are to be regarded asstandard. The inch-pound units shown in parentheses are forinformation only.1.3 The following precautionary statement pertains only tothe test method portion, Section 7, of this specification: Thisstandard does not purport to address all of the safety con
5、cerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
