This standard lays down the method of test for determining the wet volume of asbestos fibre, which is an important metric for evaluating the bulking characteristics and fiberization level of asbestos used in cement products.
Method of test for determination of the wet volume of asbestos fibre
Quick Reference Values
Standard testing temperature27 ± 2 °C
Standard relative humidity65 ± 5 %
Reading accuracyTo the nearest 1 ml
Key Formulas
Wet Volume = V (Volume of sediment in ml) / M (Mass of sample in g)
Practical Notes
Testing must be performed with strict health and safety precautions (PPE, masks) because asbestos is a known carcinogen.
The wet volume test is an indirect measure of the degree of opening (fiberization) of the asbestos fibres, heavily influencing the manufacturing of asbestos-cement sheets and pipes.
