The meetings should be held to start with every two months and - then the interval extended or shortened depending on the situation as it develops An interval of several months is likely to be so . long that the objects of the meetings would not be served 4 The activities of NIMA would be for the benefit of the industry particularly with respect to specifications regulations etc. the direct contact with government people would be confined to areas in which collective representation is beneficial and would in no way encroach on the work of Washington representatives of / - the various companies ce - a The National Academy of Sciences should have different treatment and handling than the government specifications writers and engineers The . latter group is not interested in more data does not have time to inter- _ pret it and much prefers us to provide suggested specifications or can material which be directly used in specifications or recommendations One or two of the specification writers would even glad to write the NIMA name into the specifications if NIMA would provide a standard or a specification which they could apply directly in their specifications or standards ; . so +=" - an Loos vo This whole field seems to be a ripe opportunity and any delay at this time will only encourage these people to turn in some other direction Now however we have their attention and we should not allow any time to pass * before taking advantage of the situation a The Thermal Insulation Society is attempting to compile a handbook . Other organizations have attempted it and some have actually gotten out - some kind of compilation It appears however that the NIMA support should be placed behind the ASHRAE Guide and Data Book inasmuch as that is the most highly regarded publication and inasmuch as there is . already material of a suitable nature in it and inasmuch as that organization _ has been working for several years on an application chapter to supplement the existing material There is danger of giving information to a group and having them use it in a manner which would confuse rather than clarify the question of how to select and apply thermal insulations With ASHRAE the NIMA Secretary as well as industry representatives are members of the Committee and can have a hand in guiding the use to which the in- formation is put 000277 PRODUCT IDENTIFICATION os The Committee should 7 on feels that some identification be placed all ' standard products This is true especially on products used for duct insulation ne oo, oe _ The rock slag and glass manufacturers will be polled to determine their desires in this matter ae | 7 REVISIONS TO SPECIFICATIONS 1.
