Organization: ASTM International
Publication Date: 10 August 1998
Status: inactive
Page Count: 6
scope:

1.1 This test method covers the measurement, on a laboratory scale, of the contribution of asbestos fibers to the strength of asbestos-cement products. The results obtained are used in the primary assessment of different fiber grades prior to their application on a larger scale.

1.2 This test method covers the determination of the modulus of rupture ( MR ), adjusted to a dry density of 1.60 Mg/m ( MR A ), of asbestos-cement test specimens that contain the asbestos fiber to be evaluated at a concentration of 10 weight%, whereby the degree of fiberization of that fiber is specified in terms of specific surface area as determined by Method D2752. The relative reinforcing value of the fiber under test is established by comparison with MR A values obtained with a fiber of known characteristics at a fiber concentration of 10% and a dry density of 1.60 Mg/m (1.60 g/cm ).

Note 1-The adjusted modulus of rupture ( MR A) at any intermediate fiber concentration may be interpolated from results suitably determined over a limited spanning range of fiber concentrations. For example, the MR A at 10% fiber concentration may be graphically determined from data at 3 and 17%.

1.3 The values stated in SI units are to be regarded as standard. The inch-pound units are for information only.

1.4 This standard does not purport to address all of the safety problems 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 Section 7.3 for specific precautionary statement.
