The decision retched et this Joint testing wee that since the liber Testing Comittee had already sent oat to all sanbera samples for the T. 4 R. isntruaent with detailed instructions for the test, that It would be less confusing to follow through on this series of teste before eebarklog on e new series ee planned at tho Kav 12th. acetlng of the Technical CoAlttee. Sables were distributed to all member early in the year by the Fiber Tasting Ccn'dtte* consisting of asbestos fibers over a range of M. R.e aceo^aoied with instructions for testing the senplet. harpies t.ere to be tooted by rotating *'r^. 90, 160, and 270 to ascertain effect of sample position. Alee the effect ef edjeccnt bodies was to be determined by plating a heavy steel pipe near the T. 4 M. instrument to see what effeet this would have on the reading. ) ~v c i j i >c KDrtTrss t Ttcicnaa cowtttee Revision of ASTM Specification P 299 end D 379 Following the May 11th. end 12th. meting, the 6th.
