CTFA Task Forco on. Round Robin Testing 'of Consumer Talc jai Products' for Asbestifrm Amphibole Minerals
A meeting of the above CTFA Task Force was held on May 17, 1977 at CTFA headquarters in Washington, D. C. . Those in attendance were:
Murray Berdick, Chesebrough-Pond's Regina Gallagher, Johnson & Johnson Research R, W. Grexa, Cyprus Industrial Minerals Ray Krammes, Whittaker, Clark & Daniels George Lee, Johnson & Johnson Baby Products Louis Murino, Cyprus Industrial Minerals Herbert Ohlmeyer, Colgate-Palmolive C. J. Parmentier, Cyprus Industrial Minerals James Rodgers, The Mennen Company George Sandland, Bristol-Myers Company John Schelz, Johnson & Johnson .....CHAIRMAN Joseph Simko, Colgate-Palmolive Ian Stewart, McCrone Associates C. S. Thompson, R. T. Vanderbilt J. J. Travers, Avon Products, Inc. Clifton Wilson, Food & Drug Administration Ronald Yates, Food & Drug Administration Norman Estrin, CTFA Mort Westman, CTFA
Dr. Schelz opened the meeting by asking participants to intro duce themselves and then stated the Task Force objectives as:
1. "Determine whether or not any 1976 production of major commercial talc products contain asbestifrm amphibole contaminants.
2. Test and verify CTFA Method J4-1 for this purpose assurance that method is' accurate,' reliable and practical
He then reported, these objectives have not yet been achieved.

Note: Mt. Siani had not submitted results as of the meeting date (May 17, 1377)
With reference to discrepancies in results reported for products #3> #5,- and #7, Dr. Schelz cited, as the principle source of problems, the optical microscopy and dispersion staining called for in Part II of the method (CTFA Method J4-1).
Dr. Schelz then proposed a round robin partial retest employing a TENTATIVE REVISION of Part I (CTFA Method J4-1) which incor porates suggestions from W. McCrone and other microscopists and in which instructions are more clear and precise. Copies of the TENTATIVE REVISION were distributed to those in attendance. As outlined by Dr. Schelz; sets of 4 coded samples, comprised of any random combination of the following:
a) a standard prepared by "Spiking" talc with an amphibole mineral and
b) the three products indicated by the first round robin test to provide inconsistent results (i.e., #3,5 and 7 see Table above) -would be distributed to participating labs in the new round robin test. All companies would be eligible to participate in this partial retest and the code would remain in Dr. Schelz's posession (as has the first-test code),
Dr. Schelz proposed that the GSHA Field Memorandum be retained the working definition of fibrous asbestiform (emphasis placed 5 length: 1 width provision) for the remainder of round robin testing. This proposal was put to a vote and approved and the Force agreed to initiate the round robin partial retest.

Task
Drs. Estrin and Schelz urged that CTFA procedure be adhered to, and that only CTFA Standard Tremlate be used, in the retest.' Dr. Schelz reminded the group that while discussion appears to be narrowing down to the 2 amphiboles, tremolite and anthopyllite, we are not attempting to identify these as such, but only as

amphiboles. Dr. Schelz suggested that no attempt be made to prevent more than one participant from sending samples to the same outside testing lab because results could provide insight into that testing laboratory's intra-laboratory dependability. After a brief discussion of the above, the Task Force, having no further business, adjourned.
