24、 of filled containers. Each sample-filled container selected as specified in 4.2.2 shall be examined by the Government inspector for defects of the container and the closure, for evidence of leakage, and for unsatisfactory markings. Each sample-filled container shall also be weighed to determine the

25、 amount of contacts. 4.3.2 . The dry ingredients and the magnesium chloride flakes selected in accordance with 4.2.3 shall be mixed (separately for each container) in accordance with the manufacturers instructions and subjected separately to the tests specified in 4.4.2 through 4.4.6. When specified

26、 (see 6.2), the performance test specified in 4.4.7 shall also be conducted.

When specified (see 6.2), tests may be omitted when the lot consists of 2,000 pounds or less. 4.

27、4 Test methods. Test methods shall be as specified in 4.4.1 through 4.4.7. 4.4.1 Preparation of specimens. Unless otherwise specified, specimens of the sizes required for the following tests shall be made of clean liB-inch thick ordinary steel plates. The plates shall be primed with a brush coat of

28、adhesive conforming to MMM-A-121 and allowed to dry for 2 hours. The covering shall be prepared following the manufacturers instructions, using a gauging solution of 21.5 plus or minus 0.5 degrees Baume, and trowelled on the primed steel plates to a thickness of approximately 1/2 inch by means of te

29、mplates. The specimens shall then be cured for 96 hours at room temperature before conducting tests. Unless otherwise specified herein, all tests shall be conducted at a temperature of 70 to 75F and with a relative humidity of 50 2 percent. 5 ,L (1“ “IolJ I lrTJ II 01 In., Jll“JTl I“I1U,“1 I UfllU.I

30、 u,u“- Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-D-23l34ASH 4.4.2 Weight. The covering shall be applied to three 6-inch square steel plates (see 4.4.1) that have been previously measured and weighed to the nearest 0.01 gram. The length and

31、width shall be measured to the nearest 0.01 inch, and the thickness to the nearest 0.01 inch. The thickness shall be determined by measuring the steel plates with and without covering at 16 equally distributed points on the specimen by means of a dial thickness gauge and a template. The difference i

32、n thickness of the steel plate and the coated steel plate shall be averaged to determine the thickness of the material. From the difference between the weights of the coated steel, the actual weight of the material shall be determined and then computed in pounds per square foot per l/2-inch thicknes

33、s. The final computed weight shall be the average of the three specimens. 4.4.3 Indentation. One specimen 6 inches square shall be used including the full thickness of the covering and steel base to which it was applied (see 4.4.1). Three indentations shall be made on the specimen and the results av

34、eraged. The center of each indentation shall be not less than 1-1/2 inches from the edge of the specimen and not less than 2-1/2 inches from the center of the adjoining indentation. A load of 2,000 pounds shall be applied on the deck covering for 30 minutes by means of a circular indentor with a cro

35、ss-sectional area of 1 square inch and a radius of 1/64 inch on the perimeter of the indenting flat face. The thickness of the covering shall be measured with a micrometer dial gauge using a 4-ounce weight and a 1/4-inch diameter flat foot on both sides of the specimen before and after the 2,OOO-pou

36、nd load has been applied. The thickness of the steel base shall be subtracted in each case. The indentation shall be taken as the percent change in the thickness of the material. 4.4.4 Water absorption. Three specimens inches square by 1/4-inch thick shall be prepared by applying the surfacing to oi

37、led surfaces of steel plate in such a manner that upon drying the specimens will not adhere to the plates. Each specimen without the steel backing plate shall be weighed dry, dipped into tap water at room temperature, lightly wiped on all surfaces with a paper towel, and again weighed to the nearest

38、 0.01 gram. Immediately, after weighing, the specimen shall again be immersed in the tap water for 24 hours, lightly wiped, and again weighed. The percent gain in water shall be based on the weight of the dry specimen and the difference between the weight after 24 hours immersion and difference in w

39、eight after dipping and wiping. 4.4.5 Resistance to impact. Two specimens 6-inches square shall be used, including the full thickness of the covering and the steel base (see 4.4.1). Each specimen shall be tested separately while being firmly held on a solid, horizontal base. A 2-pound solid steel ba

40、ll shall be dropped vertically from a height of 8 feet so that the impact will be at the center of the specimen. Each specimen shall be subjected to two impacts of the ball. 4.4.6 Bond strength in shear. Six specimens shall be prepared by applying the covering on 2 by 2 by liB-inch thick mild steel

41、plate to a thickness of 1/4 inch by means of a template so that 1 inch of the steel base is exposed at one end, and 3 inches are exposed at the opposite end. Specimens shall be tested by measuring the load required to shear the 2-inch square area of the covering from the steel plate by means of a sh

42、ear test jig as shown on figure 1. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-D-23l34A(SH) 4.4.7 Thermal conductivity. Thermal conductivity shall be determined in accordance with ASTM C 177. 4.5 Toxicity. The contractor shall have the toxi

43、cological formulations and associated information available for review by the contracting activity to evaluate the safety of the material for the proposed use. 4.6 Inspection of packaging. Sample packages and packs, and the inspection of the preservation, packing and marking for shipment, stowage an

44、d storage shall be in accordance with the requirements of section 5 and the documents specified therein. 5.
