ASTM C300, C-28I, C-378, C-262 and C-280; no negative ballots received, and therefore will be forwarded to either C-16 Committee or the Administrative Committee on Standards for further action* 2. ASTM C-392 Mineral Fiber Block or Board Thermal Insulation for Elevated Temperatures. ASTM C-263 - Mineral Fiber Blanket Insulation (Metal-Mesh Covered) (Industrial Type) Comments received on these specifications were of an editorial nature and will be discussed when the appropriate ASTM C-16 Subcommittee meets* REVISIONS TO FEDERAL SPECIFICATIONS The Elevated Temperature specification and Low Temperature specification were reviewed and revised in accordance with the comments received dur ing discussion* The revised specification will be circulated to the Com mittee for approval and/or comments* fiC 422167 p 0078 VW-05811 r z PROPOSED FEDERAL SPECIFICATION ON DUCT LINERS Ur. Erast is to be asked to write the specification including the requiremerits contained in the duct line? specification written by the Prefabricated Duct Committee* PERFORMANCE STANDARD FOR FACINGS Mr. Cubar will present the completed document at the next Committee meeting, PROPOSED REVISIONS TO MIL*1-742 Comments are to be sent to Mr. Barnhart in order that NIMA can send them to the Bureau of Ships, The subject of fiber diameter in specifications was discussed. It was decided that the various agencies whose specifications contain fiber diameter will be asked to delete the requirement as fiber diameter is not a physical requirement. Ae long as the material meets the physical re quirements in the specification the fiber diameter is unimportant. x Mr. Barnhart was asked to poll the manufacturers to determine what fiber diameters (diameter ranges) arc applicable to fine fiber, textile fiber and wool fiber products. COMMERCIAL STANDARDS The Committee decided that CS-105 and CS-ll ? were out of date and no longer served a useful purpose, and suggests that the documents be rescind ed. The Rock St Slag manufacturers and Glass manufacturers will be polled on this subject. OTHER BUSINESS 1. It was asked that consideration be given to revising AJJTM C-167. 2. The Bureau of Standards is to be asked if it is feasible for them to set up standards of measuring fiber diameter by the Micronsire ADJOURNMENT There being no further business, the meeting was adjourned.

P, Hoopes called the meeting to order at 9:13 A, M, with the following in attendance: H. P Hoopes L, L, Collogue Butt Tower V/, P. SifacUir V. L, Miller A, Kevlin D. A. Davie E. F. Ott, Jr. V?. R. Selpt Fibreboard Paper Products Corp, Mundet Cork Corp. Johns-ManviHe Sales Corp.

SIZES At our last meeting we agreed to poll the members whether or net to adopt the ASTM Table of IPS O.D's for Copper Tubing. The returns of the April 23 ballot were 5 in favor, 2 opposed* V, L, Miller said his tubing sires do not now conform to this proposal. W. R, Sinclair commented that the Unibestos Tubing 0.0. *s are not the same as IPS for at least up to the 3 inch nominal 10 sizes. It was decided to defer further action until the next meeting, in the interim, the two dissenting members will determine from their companies what the possibilities are for them to produce tubing 0.0. *e to the JP& system of nesting sizes. Mr. Hoopes pointed out that in some tubing sixes, using IPS O.D.'s, the thicknesses are considerably above the nominal thickness. He suggested each member talk to their management about the possibility, in such cases, for an economy in material by using the next lower IPS O. D. and thereby reduce the thickness to something nearer nominal, TRUENESS AND SQUARENESS OF PIPE AND BhOCK Since an ASTM proposal for block has been balloted and will be discussed by their Subcommittee T-VIE next week, there would be no need for us to consider it at our meeting today. rrr p 0O&& Six photographs of Paul Losse*s were preseated illustrating the different types o misfits which can occur between pipe covering half-sections on an appiicatioa. It was agreed that these photographs were necessary to identify the type of misfit and to show the means for measuring its extent* However, the one illustrating a tapered longitudinal joint opening should show the one end strapped tightly and the other "open" end as being free for measuring the extent of this gap* INTERIM FEDERAL SPECIFICATION BH-I-0055lb This interim specification for cellular glass covers four classes based upon factory applied finishes (jacketing)* It was explained that NIMA go on record as opposing any specification in which the jackets, constitute a part of the specification* If jackets are desired for one use or and:her or are a necessary part of the insulation, than such jackets should only be listed as to their availability or reference be made to specifications, if and when such specifications are issued for the jackets themselves. Jack Barchart will take up this item with the proper Government agency* PROPOSED MILITARY SPECIFICATION M2L-I-27S2D The proposed draft of MIL-X-2781D for pipe, dated 29 June 1962 was reviewed with the following changes recommended: Par 1.2, Grade 1 Change "600 F" to SSO F and delete "Class b - compounded" Reinstate the Oaade 22 of MIL-J-278JC, but delete "Class c - Fibrous" and delete "Class d - Compounded" Par 1*2, Grade IQ Delete "Class e - Compounded" "Claes f - Fibrous" Mr. Sinclair opposed our eliminating these definitive terms, "Compounded" and "Fibrous"* The group, however, preferred to strike out any reference to compositions and to substitute in their place the following classification wherein each one is identified by its maximum density. If this is not satisfactory to the Military, then we would agree to retain the existing terms. If retained r however, we would ask for an additional paragraph to define these terms* The classification we propose on the basis of density is: Grade l - Temperatures up to $50 F Grade U ~ Temperatures up to 750 F Type 1 *- 13 density maximum Type 11-15 density maximum MC 422s$r P nn$ / Grade 1U - Temperatures up tc 1200 F Type I - IS density maximum Type II -- 20 density maximum Type XU - 26 density maximum The group at this point raised a question which Jack Barnhart is to present "Are there any needs of any Government Agency for insulation for pipe temperatures above 1200 F?" Par 2. 2 Other Publications Under the ASTM liet of specifications their latest revision should be used rather than tieing one down to a specific date of issue, (Also: follow thru in any applicable subsequent paragraphs.)

Mr. Barnhart was asked to talk to Mr. Vf, C. Tamer and try to ascertain aa to why this happens. (Mr. Turner said that the primary reason this occurs is due to the sudden increase in costs of kisul&tion for various pipe else*. ) It was decided that smoothing out the values would he Justified on the following basis; COMMON BASIS OF PRESENTING ECONOMIC THICKNESS (Based on average conditions) ECONOMIC THICKNESS TABXJSS (For pipe and flat insulation) 1.

Mr* Barnhart was asked to arrange a meeting of the special coordinating committees on this subject* Q*P'S OF THERMAL INSULATION FOR TUBES The Molded Section reported that their section could not come to an agree ment on insulation outside diameters for tubes* Mr* Barnhart was asked to circulate to the Committee the ASTM Table for IPS dated January 31, 2962. requesting approval and/or comments as to the acceptance of the Table for O* D. *a for tubes. The comments are to be returned to the N1MA office within 30 days* A summary of the results will be circulated to the Committee prior to the next T & R Committee Meeting* OTHER BUSINESS (a) Two requests had been received asking for recommendations for supports o* cold and refrigerated piping* Mr. Barnhart was asked to write to the individuals informing them that basically the problem was not NXMA'b responsibility for such design, and to advise them as to what factors should be taken into account when designing the supports.
