Most of those present agreed that tho insulation manu facturer certified only to the quality of the insulation* It wu3 also brought out that the prime contractor is responsible for the work and quality of the materials furnished under the contratt* It was suggested that this subject be taken up directly with the agencies requiring affidavits. REACTIVATION OF FEDERAL SPECIFICATION BOA HD This subject was carried ever from the previous meeting. The reactivation c the Federal Specification Board will rdcuire appro priations of money and authority to operate from Congress, It was thought that the best way to approach the problem was to get other Associations interested and sponsor a joint effort in this respect* It was suggested that in order to nipodite the writing of specifications that NEMA cooperate directly with the various government agencies involved and write interim specifications. The following projects for NIMA to consider were broached by individuals procon? * 1, Trite a Commercial Standard on Industrial Insulation Products, 2, Trite a glossary of terms and definitions pertaining to the insulation industry, 3, Consider writing an NIMA Standard on insulation products, STANDARD WEIGHT OF CANVAS ON PIPS INSULATION Some government specifications specify a minimum weight of 2, 3 oz, per linear yard of canvas on pipe insulation* NIMA asked that the following weirjktum weights bo specified; 5% Magnesia Calcium Silicate Ldatomsaceus Silica Mineral Fiber 1. 86 oz per linear yard 1,86 " " " 1,86 " " " " p 3 nu u n I - 3- The agencies present believed that these minimums could conceivably be written, into the specifications, however for specific specifications heavier weights of canvas would be specified. One agency was interested in NIMA writing a specification on piping and jackets, INSULATION THICKNESS USED ON PIPING It was reported that BRAB was attempting to establish economic thick nesses of insulation used on heated pipes. The report will be sent to NIMA for review. It was pointed out that several manufacturers, consumers, oil companies, etc,, have made these types of studies and that it would be desirable for BRAB to hold a conference on this subject* UNDERGROUND PIPING 'L--u~ "n`" TV" ~'L"r " 1 \ It was reported that Navy Specification TSP 28 was written and ready for issuance. The specification allows one generic material to be tested in any conduit system, and if it meets the requirements, all materials of the same generic type will be approved if they meet the requirements of the Federal Specification applying. It was thought that other govern ment agencies would probably follow Y Sc D in their specifications, GSA STANDARD SPECIFICATION The suggested change from 0, 3 to 0, 03 perms for vapor barrier jackets for "water pipes" was discussed. It was explained that this concerned insulation for service water piping, roof drains, etc,, and that a universal jacket with 0, 3 perm and 25 flame spread would be adequate for this service, GSA is following NIMA recommendations in rewriting the specification OTHER BUSINESS It was suggested that NIMA provide descriptions and uses of adhesives for insulation and accessories. It was also suggested that NIMA develop specifications for flame spread, fuel contributed and smoke developed. The group was advised that NIMA recommended limiting test methods for the time being to the tunnel and radiant panel. Discussion indicated 4 that there was some confusion as to whether materials should be tested singly or in combination. The NIMA recommendation was to test the combination as it would be installed as the performance of the package is the primary concern^ ADJOURNMENT There being no further business, the meeting was adjourned.
