Historical Standard: Standard Test Method for Asbestos Strength Units<\/h4>\n
\n

ASTM D3880<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method gives a procedure for the evaluation of the strength-giving properties of asbestos fibers used to reinforce asbestos-cement products.<\/p>\n

1.2 The purpose of this test method is to determine the number of strength units that may be assigned to the sample tested.<\/p>\n

1.3 Asbestos fiber possesses the ability to impart strength to an asbestos-cement product. Every fiber grade may be regarded as possessing a certain quantity of strength-giving units. The quantity of fiber required in an asbestos-cement composition varies inversely with the number of strength units it possesses. For example, if an amount, designated by X<\/i>, of a fiber possessing 100 strength units produces a product of a given strength, 2X<\/i> would be required to produce a product of equivalent strength from fiber possessing only 50 strength units.<\/p>\n

1.4 The following definition is the basis for the strength unit test: An asbestos fiber that gives the standard strength at the standard density when used as 10 % of the furnish is defined as having 100 strength units. Therefore, by knowing the percent fiber required in the mix to give standard strength at the standard density, it is possible to calculate the strength units of a sample of asbestos.<\/p>\n

1.5 This procedure is intended primarily for chrysotile asbestos; it has not been verified whether or not it is applicable to other types.<\/p>\n

1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.<\/p>\n

1.7 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.”<\/p>\n

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 precautionary statements see 9.2.2, Note 6, and 1.7.<\/p>\n
