3、ers factory prepared reinforcedbituminous sheet used in flashing. The bitumen 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 min

4、eral powders, granules,or metal foils may be used as surfacing.1.2 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 equivalents; therefore, eachsystem shall be used independently of the other. Combinin

5、gvalues from the two systems may result in non-conformancewith the standard.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 concerns,if any, associated with its use. It is

6、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.
