All tests shall be conducted at the National Bureau of Standards or other laboratories designated by the Coast Cuard. Tests conducted shall Include density, moisture and volatile content, and heated tube test. GAF 14048 31 164.009.3(b) Density Measurement. \* t 164.009.3(b)(1) The smallest sample for density measurements of solid mate* rials shall be 12" x 12" by Che submitted thickness. Length and width measurements shall ba wade to the nearest 1/32", thickness to the nearest .01", allowance being wade of any non-flatness of the major surfaces of l the specimen. Measurements of dimensions of fibrous Insulations shall be aade to the nearest 1/16" on a nominal 12" cube assembled from sheets f of the thickness received. The average of at least 4 measurements of r each dimension shell be reported. The weight shall be determined with a scale of balance sensitive end accurate to 0.3 percent or less of the total weight. The dimensional and weight measurements shall not ba made until the sample has been conditioned one week, or longer If required to reach constant weight, In an atmosphere at 73* + 2*F., and 50% + 5% f relative h\aaldlty. ~~ 164.009.3(c) Content of moisture and volatile matter. 164.009-3(c)(l) Transfer a weighed sample cut from the density specimen, previously conditioned to equilibrium at 73* + 2*F. and 50% + 5% relative tumidity, to a previously weighed wldemouth weighing bottle provided with a glass stopper. Remove the stopper and heat the bottle and sample at 105* + 5*C. for four hours, Insert the stopper, cool, and weigh. Calculate the content of moisture and other volatiles as percent of the final dry weight of the aample. 164.009.3(d) Heated tube test. 164.009.3(d)(1) Three specimens, each l^n x IV x 2" shall be prepared from the sample submitted and dried at a temperature of 105* + 5'C. for four hours before the tese. Each specimen shall be assembled~uslng a sufficient ember of layers to obtain the prescribed IV thickness, exeepe that thin flexible tutorials stay be rolled Into a cylindrical shape approximately 2" long and lfc" in diameter or made Into a solid 2" x Ifc" * IV' by layers. A hole which will accomodate a thermocouple of 0.020" wire shall be made to the center of the specimen Into which a themoeouple of the above sice shall be Inserted to register the Internal temperature. An additional thermocouple of the same slse shall be located on the surface of the sped* men centered on one side to show the temperature at the surface for Indlcat. Ing any difference In temperature recorded by the two thermocouples. 164.009.3(d)(2) The test shall be conducted In an apparatus similar to that described In Figure 164.009.3(d). This apparatus shall be capable of developing and maintaining a temperature of 750 degrees C. In the heated tube. 164.009.3(d)(3) The heated tube shall be brought up to and maintained at a temperature of 750 degrees C. as evidenced by a thermocouple of 0.020" wire which Is Inserted from the top of the heated tube end located 6" below the top of the heated tube. During the initial heating and during the test, an air flow of 0.1 cubic foot per minute shalt be supplied from the bottom of the tube at standard atmospheric temperature and pressure. When the Inserted thermocouple has reached a steady 730 degrees C., the tempersture recorded by a thermocouple located at the wail of the heated tube and shown as Tj on Figure 164.009.3(d) shall be noted and maintained throughout the teat. 2 * GAF 14049 rif hsiTmr i 164.009-3(d)(4) When the heated tube hee reached 750 degrees C., the inserted thermocouple shell be removed end the sample with thermocouples attached shall be suspended as rapidly as possible in the heated tube with its long axis vertical by a 0.020" diameter steel wire around the outside of the specieen. The bottom of the suspended epeclsicn shall be 7" below the top of the Inner tube. Energise the platinum wire to operate at an } apparent temperature of 800 + 50 degrees c. Headings of the tampersture at the three thermocouples shall be taken and recorded not less than every l 15 seconds or greater than every minute and the test shall continue for tl f 15 minutes unless failure occurs before that time. f I 164.0090(d)(5) In order to pass this test, each of the three specimens shall meet the conditions noted below for the duration of the 15 minute Interval. For fibrous-type Insulation materials these conditions will only be ' applicable to the last 13 minutes of the 15 minute interval. 164.009-3(4(5X0 The specimen shall not flame, except that flame from painted or paper coated surfaces may be permitted for not longer than 30 seconds during the first two minutes. 16^009-XdXSXii) The specimen shall not glow brighter than the walls of the heated tube. If gloving at all, the glow shall not increase when the specimen Is removed from the heated tube. 164.009-3(d)(5)(lll) The temperatures as Indicated by the thermocouples j located at the center and on the surface of the specimen shall not rise more than 20 degrees C. above the heated tube air temperature. ;* 164.009-3(d)(5)(lv) During the test, the specimen shall not give off flamable vapors In such quantity so as to be Ignited by the energised platinum wire. 164.009-3(e) Reheating test. i 164.009-3(e)(l) Two specimens of the material, each 12" x 12" x 6", shall be prepared so that when placed one on cop of the other they form a cube one i foot on a side. A piece of steel weighing approximately ^ pound consisting of a 1-7/16" length of lfc" shafting with a thermocouple attached to Its l side shall be heated uniformly throughout Its mass to more than 900 degrees C. The temperature of the steel shall be observed as It cools In room air, .i free of drafts and It shall be inserted between the two specimens In Che * center of the faying surfaces when the surface temperature reaches 900 i degrees C. In the case of rigid or seml-rlgld type materials, hollows ri shall be cut In the two faying surfaces In the shape of the shaft so that contact of the two surfaces will be made. Three thermocouples shall be Installed between the two faying surfaces at 1", 2" and 3" from the shafting, and a 1/8" steel plate one foot square shall be placed on top of the cube to Insure a uniform pressure between the two specimens. Readings of the three thermocouples between the specimens and the thermo couples attached to the shafting shall be made at Intervals not grsater than 5 minutes for the first two hours and 10 minutes thereafter. The test shall continue until such time as the temperatures Indicated by all four thermocouples are less than 200 degrees C., or until It Is indicated that the material has failed to pass the test. -3- GAF 14050 a iE* l64.009-3(e)(2) In order to pets this test, ell of the following conditions shell he met: l64.009-3(e)(2)(l) There shell be no lndlcetlon of fleae or glow on the t exterior of the cube during the test. l 9 t 164.009.3(e)(2)(H) The sheftlng temperature et any reeding shell not be greater then at any previous reading. c I f l64.009-3(e)(2)(lll) None of the three thermocouples between the faying surfaces shall at any Instant Indicate a temperature of more than 10 r degrees C. above the temperature of the shafting at that time. 164.009-3(f) Spot check tests. 164.009.3(f)(1) Incombustible materials are not Inspected at regularly scheduled factory Inspections; however, the Cosnander of the Coast Cuard District In which the plant is located may detail a marine In spector at any time to visit any place where Incombustible materials are manufactured to conduct any Inspections or examinations deemed advisable and to salect representative samples for further examin ation, Inspection, or tests.
