After cooling the above to room temperature in a desiccator, weigh each com ponent and the filter paper containing the graphite. 10. Calculate the percent of each component using the original weight as a bases. The lubricant is calculated by difference. 5.3 ASBESTOS DETERMINATION p (ASTM D 1918) a- To determine the percent of asbestos and percent of organic matter in the outer jacket, the following procedure is used. 1. The extracted outer jacket from 5.2 is placed in a clean, weighed crucible and a burnout is performed in a 799-B38C muffle furnace for 1 h. 2. The ash is cooled to room temperature in a desiccator and weighed. 3. The original weight of asbestos is calculated using the following formulas. 4. Ash Wt. = Original Wt. of Asbestos os-- 5` x 100 . % Asbestos 6. 100 - % Asbestos - % Organic Matter 0.86 is a factor based upon a measured average loss of 14% water of orystalization when chrysotile asbestos is heated to a temperature of 799-838C. 7. The total breakdown is calculated by using the original weight of the package. Organic Fiber Content = Wt. of core plus inner jacket, plus organic matter in outer jacket. Asbestos Fiber Content = Original Wt. of asbestos m"rn>.yirn of outer jacket. 5.4 DEFINITIONS Refer to ASTM D 123 for all term definitions in reference to packing fabrics. 7 5" c*>PtAwD O-iOUK) ftloO, 12^50 CAFiTAL OAK PAKK , HiCH, 8001 13S5 44 Page -- --
