A2.1 Test procedure
QB/T 2493— 2000
2.1.1 The light efficiency tester is placed horizontally, and the angle between the upper plate and the lower panel is adjusted to (30±2)", and then the lower mouth of the funnel is adjusted so that the projection of its center point is (2002) mm from the lower edge of the tester inclined surface, and the lower mouth of the funnel is facing the operator. Pour the recorded test solution into the funnel to moisten the ends of the funnel, and rinse the two ends of the funnel with the test liquid. 2.1.2 Collect the test sample, cut off the elastic bands on both sides (including the guard edge), and place the sample flatly on the root of the test material surface F, or on the upper and lower inclined panels of the sample. Take 100m on each side from the center of the sample's inner and outer layers as the test surface, and fold the protruding parts to the upper and lower parts of the inclined plate. Fix the sample with a stainless steel clamp. The clamp does not wait for the effective code to flow deep, Figure 1. Adjust the distance between the funnel and the bottom end of the funnel to be 5mm-10mm away from the surface of the sample. Then place a beaker under the tester to collect the liquid after the sample is full:
2.1.3 Use the left hand to accurately measure the test filter: take 50mL for infant diapers, diapers/heat-release liquid standard funnel: take 50mL for adult diapers, diapers/heat-release liquid standard funnel. Then open the funnel door to allow the solution to flow to the surface of the sample and flow down along the slope into the beaker. After the filtration test, close the funnel door and wipe the bottom of the funnel. After that, there is no liquid. Take the solution in the funnel (<1mL) as the test result. If the core test material is mixed with the sample surface temperature, the test is selected as a new test. 2.2 Calculation of test results in lubricant The amount of lubricant added is expressed as the rate of the sample not absorbing the test solution (%). Each sample is marked with a strip, and the larger value is taken as the smaller value in the test of more than 7 cases. The values within the technical range of the remaining 5 cases are taken as the final test results, accurate to 1mL. If more than 2 of the 7 samples (excluding > 1 case) have test flow, the result is guaranteed to be included in the new test report. A3 Determination of backflow and leakage A3.1 Determination of backflow A3.1.1 Test procedure Pour the appropriate test solution into the funnel, wet the funnel, rinse the funnel twice with the solution, and drain the mixture in the funnel: fix it on the support with the bottom opening of the funnel facing the operator. After the test strip is ready, place it on a piece of filter paper of known mass that is large enough to be inserted and place it under the funnel. Make sure that the center point of the funnel mouth is 5mm~10mm away from the center point of the sample layer. Use the funnel to accurately measure the test liquid. For baby paper below S type (including S type), take 40mL, for M type, take 60mL, for L type and above (including L type), take 8mL, and pour it into the adjusted whole urine sample, diaper/pad special standard funnel. Take 150mL and pour it into the adjusted adult paper. Diapers, diaper pads special standard filter leak, then quickly open the bucket door to record, let the liquid rise to the surface of the sample by itself, and start counting at the same time, wait for 5m, pour the test liquid into the full bucket, the same as before, after 10m, quickly weigh the known sensitivity of the filter paper (take the upper filter paper as 1> put it on the surface of the sample liquid absorption: at the same time, press the standard pressure block of 100mm and 1.20kg on the secretion paper, start counting again, press [mi to remove the standard pressure block, weigh the filter paper with a balance - TtYKioNar KAea

's mass. Close the funnel after the test and remove the solution left at the bottom of the funnel. A3.1.2 Calculation of test results
The amount of sample added back is expressed as the amount of filter paper 1.1 returned to the filter body after being absorbed by the sample (). Each sample is 5 samples. The amount of each sample returned (G) is calculated according to the formula (AI). G=C1-G2
or: G return amount, where:
G, the mass after the filter paper absorbs the liquid,
-the mass before the filter paper absorbs the liquid.
Take the arithmetic mean of the 5 test strips as the final test result, accurate to 0.1%. 13.2 Determination of added nitric acid||tt ||As described in the work, after the rollback volume is determined, remove the sample after absorption and carefully weigh it and place it on the known weight paper at the bottom of the test paper. The net amount is represented by the mass difference of the set filter paper, and the final test result is represented by the average value of 5 test pieces, accurate to 0.1g,
