Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers woven asbestos tape having a specified minimum weight % of asbestos fiber, excluding the weight of other inorganic reinforcing strands that may be present. Asbestos tapes covered here are classified into classes (Classes A, B, C, D, and E) based on the nature of the yarns from which they are woven, grades (Commercial, Underwriter, A, AA, AAA, and AAAA) based on the percentage of asbestos content by mass, and types (Types II, IV, and VI) based on magnetic rating. Specimens shall be sampled, prepared, tested, and conform accordingly to specified chemical composition (yarn, asbestos, and wire, organic, and inorganic reinforcement content), electromagnetic (electrical insulation), mechanical (tensile or breaking strength), and dimensional (width, thickness, mass per unit length or weight, fabric count, and yarn number) property requirements.
1.1 This specification covers woven asbestos tape having a minimum of 75 % asbestos fiber by weight, excluding the weight of other inorganic reinforcing strands that may be present.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 Warning-Breathing of asbestos dust is hazardous. Asbestos and asbestos products present demonstrated health risks for users and for those with whom they come into contact. In addition to other precautions, when working with asbestos-cement products, minimize the dust that results. For information on the safe use of chrysoltile asbestos, refer to "Safe Use of Chrysotile Asbestos: A Manual on Preventive and Control Measures."
1.4 The following safety hazards caveat pertains only to the test methods, Section , described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard warning, see 1.3.
