This specification covers asbestos-cement organic-foam core insulating panels consisting of a core of insulating cellular plastic sandwiched between and bonded to two sheets of asbestos-cement facing board. Asbestos-cement plastic-foam core panels are normally nonload-bearing panels designed for exterior and interior walls, partitions, curtain walls, and other insulation and decorative purposes. Panels shall be sampled, tested, and conform accordingly to specified properties such as vapor permeability, thermal resistance, adhesive lime bond, flexural strength, breaking load strength, dimensions (thickness, width and length, and squareness), and workmanship, finish, and color.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers asbestos-cement plastic-foam core panels consisting of a core of insulating cellular plastic sandwiched between and bonded to two sheets of asbestos-cement facing board. Asbestos-cement plastic-foam core panels are normally nonload-bearing panels designed for exterior and interior walls, partitions, curtain walls, and other insulation and decorative purposes.
1.2 All measurements and tests necessary for determining the conformity of asbestos-cement plastic-foam core panels with this specification are made in accordance with the test methods covered in Sections 6 and 10.
1.3 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are provided for information only.
1.4 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.”
1.5 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. See 1.4 for a specific hazard warning.
