47、 testing in accordance with 6.7. 6.2.2 High temperature resistance Place the uninflated CBRD in a circulating air oven maintained at (70 f 3) “C for 16 h f 30 min at a relative humidity between 80 % and 95 %. After removal from the circulating air oven, store the CBRD at a temperature between 18 “C
48、and 25 “C and a relative humidity of at least 50 % for at least 3 h. Record any tackiness, blisters or other visible defects after this test. 5.2.3 Low temperature resistance Place the uninflated CBRD in a cooling chamber and maintain at (-20 3) “C for 3 h f 5 min. Then, connect the CBRDs mechanical
49、 inflation device to an air-supply delivering air at the maximum rated intermediate pressure, warmed to (-8 f 2) “C and then immediately inflate it to the cracking pressure of the relief valve. 6.2.4 Sea water resistance Submerge the uninfakd CBRD fixed to a steel cylinder of 15 litses, unless the maximum volume specified by the manufacturer is smaller, according to the instructions for use in natural sea water or artificial sea water (see annex A) of between 15 “C and 25 “C for 8 h f 5 min.
