3.1 Equipment
Pull square test machine, the measured indication should be between 15% and 85% of the full range of the dial: the reading indication error is within 1%3.2 Tool
Vernier caliper, the precision is 0.02mm
True ruler: the accuracy is 1mm.
2 Sample
4.1 Sampling position
As shown in Figure 1, the samples are placed on the side, back, quality part, and bottom of the film air bag of the material bay, and the samples are placed on the hot plate sample of the packaging side, back, quality part, and bottom. 4.2 Shape and
Test width (1520.1) mm, unfolded length ([00±t) mm, if the opening length is not, ([00±1) mm, as shown in Figure 2. Use adhesive tape to bond with the model, so that the test single opening length meets the requirement of (10 spit 1). 4.3 Number of specimens
According to the provisions of 4.1, 10 specimens are taken from each hot plate, and at least cut from 3 material films. 4.4 Specimen measurement
The width of the specimen is measured with a vernier caliper: the length of the specimen is measured with a ruler. 4.5 Conditioning
According to the standard environment and positive belt deviation range specified in G291R, the conditioning time is not less than, and the test is carried out under the same system. Www.bzxZ.net

Put the sample that has been adjusted at will, with the heat-sealed part as the center, open it", and place the two ends of the test increase on the two fire tools of the test machine. The test axis is perpendicular to the center line of the lower riser. It is required to be tight and suitable, so that the test details can be released or broken in the fire tool before the test. The distance between the tools is 50mm, and the test speed is (30020)rmrumim: Discuss the day when the test breaks If the test is broken in the interlayer, the sample shall be invalid and a new sample shall be taken. The test result shall be the average value of the test strip and the average value of the heat-sealing strength of the part. The unit is A/15mm. The three figures are taken as follows:
