C Meeting, with -P.fi zer personnel at R&D Center August 31,. 1976,. Asbestos Minerals, in Talc and Test Methods We met with Robert E. Norwood, Research Manager for Pfizer's Minerals, Pigments, and Metals Division and with Harold D. Stanley, Jr.;. Group Leader, Testing. This was a good meeting;, in that both Pfizer and J-M are essentially in; agreement as to test methods and interpreta tion of data.,.:; T.he'^Usfe.^ali:-of---the same procedures werdo: XRD,. TEM,.

They couldn't understand this ant-, we gave them portions of the same samples for testing. They promised to get back to Ed Fenner with their results. They had complete analytical data on three samples of , Pcnhorwood which they recently obtained ~from'"some'unknown source. Dy XRD they show no asbestos minerals*. They be] ieve that their lower limit of dete'ct'abiiity by XRD is 0.1% or less. `'By- `TEMidTl/three Penhorwood,samplesc showed platy talc with an Occasional fiber - less .than one filler per field. They d o n 't" regard this as^significant and would interpret this as "no asbestos mineral by 'OSHA requirements. We gave them t<hr!ee ^add'xtionai'Penhorwood samples from lour" files for additional*' stddies. Wc also discussed commercial talcs from other sources. They feel that R: T.
