Suspend each bag to be tested in an upright position by means of atleast four widemouth clamps attached to the open end. Fill the bag with water to the requireddepth.
41、 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.4.4.2 Seamstrength. DieonedumbbellspecimenconformingtodieAofASTMD412fromeach sample wate

Condition the specimens at 705F for a minimum of one-half hour. Test thespecimens in accordance with Method 8311 of Fe
43、d. 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. Within4minutesafterremovingfromthewater,apply5inchesof1/2by6-inchstripsofmaskingtapeconforming to type II of
44、 ASTM D 6123 at right angles to the printed lines so that at least 45letters are covered.
