E. Ernst - JM W. Gubar - CSG A. Kevlin - OCF L. J. Lash - JM L. H. Mills - CSG R. Peterson - OCF The agenda items were acted upon as follows 1 Temperature Limits - W. Gubar Action Mr. Gubar discussed the work conducted on the All American Vibrator on various samples conducted at 400 500 and 600 F. temperature The vibrator cycle used was that described in Coast Guard Specification 32MA3C The only conclusion that was made from these is that when the binder is completely removed from the insulation in contact with the hot surface and the product vibrated the thickness of the insulation is reduced due to the felting action of the vibration on the unbonded glass fiber Mr. C. E. Ernst thought that more research should be done to determine the proper vibration cycle Therefore the committee concluded that the criteria established at the April 15 1969 meeting was sufficient to demonstrate the temperature limits of the product However a warning should be incorporated in product literature similar to that shown in the Manville Flame Fiber Glass Pipe Insulation brochure as follows Note At temperatures above 400F a limited amount of binder migration may occur in the insulation near the hot surface of the pipe This does not impair the thermal effectiveness of Flame in any way Vibration in lines covered by . fibered insulations could cause the fibers to settle eventually reducing the wall thickness with a resulting loss of thermal protection -2- . oe It was suggested that the committee continue to of vibration cycle is needed to show the effect equipment subject to vibration study what type on the insulated Revisions to 558 - Lou Mills . Action Mr. Mills is to revise specification recommendations and submit a revised copy for is to supply Mr. Mills with the K factor plus cation . per committee approval Mr. Gubar 10 to the specifi- Revisions to 122023 - W. Gubar - Action Mr. Gubar suggested the revisions to this specification with the deletion of fiber diameter shot content binder content alkalinity and PH substitute corrosion test fire resistance substitute flame spread and add NIMA K values In the 10/9/69 meeting in New York the committee was to consider the idea of combining this specification with 545 for type 2 products Mr. and was requested in this session HHI for type 2 product and Larry Lash made the investigation to combine the following specifications 2818 15475 16411 22023 22344 23128 using Federal Specification HHI as a guide The combined specification should also include vibration fire tests and quality assurance programs The draft should be made prior to the meeting in the Fall preferably by September 1 1970. Any comments should be sent to Mr. Larry Lash or Lou Mills 4 U.L. Listings for Fire Hazard Classification - W. Gubar Action Mr. Gubar reported that U.L. has received favorable comments and Mr. Castino advised that two manufacturers are designation changing their labels to use the FHC 25 Class The 50 represents both fuel and smoke rating 50 Some members felt that they should also show the actual results on the labels This would defeat the purpose of the project However some members felt that laminators who are not multiple listees may have their products tested and this may present a problem to the glass fiber industry if they report actual data 5 Potential Health Hazards of Thermal Insulation - Jack Barnhart Action ASTM Adhoc Committee met December 22 1969 at the Philadelphia Electric Company John Mochel Chairman and Paul S. Maco Secretary Messrs Barnhart Gubar Ed Davis and other members of ASTM were present It was concluded from the discussion and data presented by Mr. Cliff Scheckler of Johns- Manville that ASTM involvement to evaluate health hazards would lead to considerable expenditures over a period of years for medical research Without such evaluation participatioinn recommendations on the establishment of standards would lead e to considerable litigation.. -3- Mr. Barnhart discussed health legislation restricting use of duct liners in hospitals aged homes etc. The bill in Kansas Massachusetts and California was killed However there is pending legislation in Ohio Kentucky and Indiana There is also a concurrent resolution in Kansas and California authoriz- ing the legislative committee to vote on the provisions to make a study of this problem The resolution in Kansas was killed The resolution in California is still pending Jack Barnhart also discussed the pending bill before the New York Environmental Board concernitnhge health hazards of duct liners There will be a hearing this summer on this subject Mr. Barnhart also advised that the Asbestos Workers Union willpolution campaign against glass fibers by associating it to air pollution Revision to MIL - Al Kevlin . Action Mr. Kevlin is to incorporate all the comments and draft the new specification The meeting adjourned at 3:00 Respectfully submitted Walter Gubar Chairman Mineral Fiber Section
