It was agreed that intermediate meetings be held as required. The other was to strengthen liaison with Government agencies through the Government T&R Committee.

McAllister would undertake, with the assistance of other T-VIII members, to propose resolutions for the negatives at the June 27 meeting of T-VIII.

One such class would group products with -o;-:imum flams spread of 25 and smske developed of 50. ( 2- For the information of those present from the Molded Section, J. 3, Dcrsey reviewed potential industry problems connected with establishing pipe in sulation systems at UL, as covered in the June 24 meeting of the Mineral Fiber Section. Other Business A. Kevlin questioned the maximum binder limit in MIL-I-2818A, recommend ing deletion of the requirement with committee review of the specification and upgrading of the combustibility requirements. MIL-I-742(c) was also questioned as to the application of combustibility requirements to specific type products, with a recommendation for clari fication. C. E. ERNST (
