Page 2 Organic Modifiers The only detectable difference of the organic modifiers is a slightly courser CNSL particle. Focusing on the 40 mesh fraction, ^the 1976 material typically displayed 16 percent of weight retained, while 1978/1979 material is typically 20 weight percent, with a specification range of 8 to 25%. Inorganic Ingredients The only noticable difference of the inorganic ingredients is the wet volume of the asbestos fiber. While all data is well wifchin the specified limits of 140-260 cc, 1978/1979 fiber displays a wet volume 10 to 20 cc lower than the 1976 fiber. 2. Physical Properties Gogan Hardness & Specific Gravity Data for the 1976 thru 1979 period does not indicate any sig nificant trend. The only detectable trend is an approximate 3 gogan point increase over the three year period. With an allowable hardness range of 15-41 gogan. Acetone Extract The average 1978 extract is .76 percentage points higher than the 1976 material. The average 1979 extract is .06 percentage points higher than 1976. The specification for acetone extraction is 4.0% Max. SCI 02410
