The determination of wood fiber in asbestos-cement products is necessary because such fibers may be added when multi-wall paper bags containing the asbestos are included in the batch formulations, or cellulose may be added as a processing aid during the manufacture of the products.
Although moderate concentrations of wood fiber usually have a negligible effect on product durability and performance, higher concentrations can have deleterious effects on products exposed to moisture and thermal shocks.
1.1 This test method covers the determination of the cellulose content of asbestos-cement products. Refer to Note 0 and Note 0.
1.2 Before this test method can be used for the determination of other organic substances in asbestos-cement, it must be ascertained that accurate results can be obtained by correlation trials with known concentrations of the organic substances in question present in samples of asbestos-cement.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
