Tests shall be conducted as follows:4.4.1 Leak integrity. Suspend each bag to be tested in an upright position by means of atleast four wid
40、emouth clamps attached to the open end. Fill the bag with water to the requireddepth. To avoidcondensationofwater fromthe surroundingair thewater shouldbe atapproxi-mately room temperature. Let the water-filled bag hang for the required time period and ex-amine the outside of the bag for leakage.4.4
41、.2 Seamstrength. DieonedumbbellspecimenconformingtodieAofASTMD412fromeach sample waterproof bag. The full width of the seam shall be within the constricted portionof the specimen and the long dimension of the specimen shall be approximately perpendicularto the seam. Condition the specimens at 705F f
42、or a minimum of one-half hour. Test thespecimens in accordance with Method 8311 of Fed. Test Method Std. No. 601.4.4.3 Marking. Submerge each waterproof bag to be tested in water at 705Ffor30minutes so that the printing will be wet. Remove the bag from the water and wipe dry. Within4minutesafterremo
43、vingfromthe water,apply5inchesof1/2by6-inchstripsofmaskingtapeconforming to type II of ASTM D 6123 at right angles to the printed lines so that at least 45letters are covered. Place the bag on a hard smooth surface and roll a 10-pound, hard-sur-faced, hinged roller with a diameter of approximately 5
44、 inches over the applied strips threetimes.Therollershalltravelatapproximately12inchesper10seconds.Astripofpapermaybeapplied to the adhesive side ofthe extending1-inch sectionof the tape to prevent adhesiontothe bag during rolling. Immediately after application, double back the free end of the tape
45、atabout180degreesandpeel thetapeslowlyandevenly fromthe bag. Examinethe printingandverify that no more than five characters are illegible.4.4.4 Low temperature resistance. Test the material specimens in accordance withMethod5874 of FED. TEST METHOD STD. No. 191, except the specimens shall be exposed
46、 to thetemperature specified on Drawing 5-75-3 for not less than one hour.5. PACKAGING5.1 Packaging.
