ASTM C1120/C1120M-98 (R2019) PDF Download

The ASTM C1120/C1120M-98 (R2019) standard describes a procedure for determining the fines content of asbestos fibers through a washing process using water on a specified sieve.

This test method offers a quick and straightforward way to evaluate the fines content, which refers to the smaller particles or impurities present in asbestos fibers. The equipment required for the test is simple and easy to use, and the technique involved is not demanding, ensuring that it can be carried out efficiently.

The fines content obtained through this test method is comparable to the results obtained by other screen classification test methods, such as Test Methods C1121 and D2589. This indicates that the wash test provides a reliable approximation of the fines content of asbestos fibers.

It is important to note that the standard includes a warning about the hazardous nature of asbestos dust. Breathing in asbestos dust can pose significant health risks to individuals. Therefore, it is crucial to take appropriate precautions and minimize the generation and spread of dust when working with asbestos-cement products. The standard references a manual on preventive and control measures for the safe use of chrysotile asbestos, serving as a resource for ensuring safety during asbestos-related work.
