    This specification covers the standard for corrugated asbestos-cement sheet products. Such products are proposed for use in weather-resistance surfaces of roofs, walls, and other building structure elements and for other decorative and function structures as well. The sheets and accessory shapes shall be composed of a mixture of asbestos fiber and hydraulic cement. Products shall be formed under pressure and undergo curing and may contain inert mineral pigments, mineral fillers, curing agents, and coatings. Physical requirements such as flexural strength, moment capacity (bending moment) and water absorption shall be in accordance with the test methods specified here. If a sample fails to meet the requirement of this specification, a second sample from the same lot shall be tested. The result of the retest shall be averaged along with the original test results to determine compliance.

    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. Scope

    1.1 This specification covers corrugated asbestos-cement sheet products and lists accessories used in conjunction with application. Corrugated asbestos-cement sheets are designed for the following purposes:

    1.1.1 To provide weather-resistant surfaces of roofs, walls, and other elements of buildings and structures, and

    1.1.2 For decorative as well as functional uses in any area where a corrugated sheet may be advantageous.

    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 chrysotile asbestos, refer to “Safe Use of Chrysotile: A Manual on Preventive and Control Measures.”2

    1.4 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.
