Standard Test Method for Organic Fiber Content of Asbestos-Cement Products
Also Known As:
The ASTM C458/C458M-98 (R2019) standard is titled "Standard Test Method for Organic Fiber Content of Asbestos-Cement Products." This test method is used to determine the organic fiber content in asbestos-cement products. The standard specifies the use of three apparatuses: a sieve, a drying oven, and an apparatus for the determination of total carbon by direct combustion. Hydrochloric acid is recommended as a reagent in the testing process.
The organic fiber content is calculated using the test results, and the standard provides guidance on determining the repeatability of the mass of organic fiber content for both low and high concentrations.
A warning is included in the standard highlighting the hazardous nature of asbestos dust and the associated health risks. It advises minimizing the dust when working with asbestos-cement products and refers users to a manual for preventive and control measures for the safe use of chrysotile asbestos.
