NIMA -- ? & R CCMMI Mineral Fiber Section March 26, 1971 ^ftie spring scheduled meeting of the T1R Committee, Mineral Fiber Section, convened at 9 a.a. at the Sunsaltt Hotel in New York City with the fcllowing members in attendance: C. E. Ernst--JM V. Gubar*-CSC V. T. Irwin--PPG L. H. Mills--CSC The following agenda items were discussed: (1) SUGGESTED REVISIONS TO FEDERAL SPECIFICATION H5-I-558 (L. Mills^ Action: The revisions sent by the Cosssittee members were dis cussed and the items encircled in red in the attached specification were to be deleted from the specification. The Committee requested that each manufacturer send a list of products that they would sell under Class I of Table II, Page 7* Claes I product is designated as a block or board but not load bearing. It was also re quested that Lou Mills advise the Federal Supply Agency that the manufacturers requested that the specification retain the rigidity test to keep blanket from appearing in Table II, Class I. Also Lou Kills is to set a neeti date with Federal Supply and present our comments. (2) ACOUSTICAL PERFORMANCE OF DUCT LINERS AND DUCT SYSTEMS (v. Gubar' Action: V. Gubar informed the Committee that CSC had their 1.5** duct liner tested and each member had received the tent data from Riverbank. V. Gubar was to call Riveroar.k and determine what materials were received sad advise the members who were delinquent. The subject of acoustical performance of duct systems va discucsed. C. Ernst and the writer informed the Comm-tt that thlo subject came up at the Duct Systems Committee meeting. What is needed is a test method for the octcm nation of attenuation of sound in ducts. The writer informed the Committee that Bolt, Bemnic k Newman is capable of doing this type of work and that it may sc to the benefit of NIVA to have 4 test conducted oy this group on member ducts. This subject will be discussed in further detail at the next meeting. (3) NAVAL SHIPBOARD FIRE SISK CRITERIA (V. Gubar) Action: Phase I of this program had as its objective to survey the fire test criteria used in the selection of material for ship use, and suggestion of possible codifications to the present material specification to Improve fire safety. For insulation materials the flnmespread and smoke were considered by the report as the most important properties. The report stated that smoke movement vas much faster and more extensive than flamespread and often becomes a core disabling factor than the actual spread of fire. Mr. Lou Mills pointed out that this is a five (5) years program and that the second phase vould be to make a large scale fire study to investigate the contribution of material in which the criteria vas set by the radiant panel, potential beat and smoke density chamber test. Mr. V. Irvin Informed the Committee of a very severe situa tion in Nev York, Dallas and Fort Worth. It appears that codes in these cities are written utilizing the heated tube test as the criteria for incombustibility. 7ne Nations Building codes use the heated tube test, IC30 uses the heated tube test and Flash Point (AS7X-093}--3GCA and Standard Codes uses the heated tube test. V. Gubar is to vrite to Jack Bono at UL Laboratories con cerning the problem of fire rating by codes and determining vhat action UL is to take concerning the use of heated tube test instead of the flamespread test. Mr. Irvin also brought an article appearing in the Jsr.., 1971 FIRS JOURNAL entitled -Rev York Office Building Fire" (copy attached).- Mr. Erast discussed briefly the BRA3 Report on "Fire Loans In Buildings" and Lou Mills is to get copies for the Com mittee. (k) COMBINED MILITARY SPECIFICATION (L. Lnch) Action: Mr. Lach is still working on the project. (5) coraiNfD ast!'. stzc:?:ca?:c:: cx mineral fiber Action: Mr. C. E. Ernst is still working on the project. (6) SUGGESTED REVISIONS TO nH-I-5*5 Action: W. Gubar has received members concents and will revise the specification and send it for convr.er.ts. When all of the acoustical data is received, this information will be incorporated into Table II. (7) NEW BUSINESS -- FACING U JACKET SPECIFICATION (L. Mills^ Action: Lou Mills suggested that NIKA write a specificav.or. on Jackets incorporating tensile strength, fire test, moisture vapor transmission, and puncture. It vac his thinking that we should have three types of jacket for pipe insulation: (l) Jacket for consealed spaces, (2) Jacket for exposed spaces and (3) glass cloth type jacke There is presently a Committee in ASTM in which Mr. tuba 1 and Mr. Mills are cambers working on facings and Jackets \ for insulation. No conclusions were made as to vast vc \ should do but each Committee member is to think about N 1 this problem and come prepared to discuss it sore fully | - at the next meeting. (8) ' COEFFICIENT OF FRICTION Action: Mr. Irvin informed the Committee that Paul Loose .-.ad written the method for coefficient of friction ana --nut it would be prepared during the week of April 1c to have the Committee at their testing laboratory m Shelby North Carolina to show us the equipment. The meeting adjourned about 3 ? VC/meb enc. Valter Gubar
