The CCF Test Method shows Thermobestos to bave less dust than Kaylo which might be expected as Thermobestos has molded surface areas whereas
. ,
Kaylo blocks are cut and hence will have residual saw dust on the surface I have in my files all of the details of the exact procedure that Union Curbide follows in collecting and analyzing dust samples I am not too certain that their procedure is representative for the general case but
It is also obvious that the present OCF Test Method 07B is not answering
vur busio dust problem
1 recommend that as soon as man power permits our Test Method Development Group begin the assignment of more completely evaluating the cust problem and evolving a method which comes closer to evaluating all of the facets of the dust problem This method should be made applicable
