Special flash can be months of parts, the new wave center is applicable to the dry part, GB/T198-5.120H05 coating through the steel surface treatment spray cleaning gold thickness test method 1 Guo division, detailed S2 [55, D 3 equipment In addition to the normal laboratory equipment, it should also include a good equipment: 3.1 about, standard scene precision U,01g, 3.2 drying, constant temperature capacity 11 ° 3.3 container or tray. Point and have enough volume to make the sample level can be selected 1 layer. 3.4 Desiccant, containing a desiccant such as cobalt chloride gel. 4 Sampling According to the provisions of TT1S81G, 2001, take a representative sample of the test product and seal it for storage. 5 Step Take two samples for measurement. 5.1 Test sample Place the sample in the container (3.5) into the container (3.2). Keep the container at room temperature for 15 minutes. Then move the container to the container (3.4) and cool it down. Use a large balance (31) to weigh the quality of the container and compare it with 1. Then use the container to weigh 10 grams of test material, accurately to 5.2 determination Put the container with the test material into a drying oven (S.2) containing only (11C-5) and dry it for a few minutes: then weigh the container until the remaining moisture is cooled in the drying chamber: then weigh the mass of the dried material in the container to an accuracy of 0.1 and calculate the moisture content M of the dry test material. Express it as a percentage according to the formula (1): = mx 100 The numerical value of the mass of the test sample before heating and drying, the unit is g (g); the numerical value of the mass of the test sample after heating for ten minutes, the unit is g (). If the two determination results differ by more than .05% (absolute value), then according to Chapter : Calculate the average value of the two valid determination results. The calculation result is accurate to 0.01%. 7 Test report The test report shall include the following contents: According to the international standard C1616.7--2005 (IS111253, core) the test results: the difference between the test method and the standard; Test period: Current tester.
