Test principle :
Put the sample on the glue film, clamp it with a sample, and then evenly apply the pressure Roll up until the sample was broken. The sample is resistant is the high value of the hydraulic pressure.
1. Sample clamping system
The diameter of the upper pin plate (31.5 士 0.5) mm, the diameter of the lower plate (31.5 士 士 士 士 士 0.5) MM. The upper and lower clamps should be concentric, and the error of its 蕞 must not be greater than 0.5mm. The two clips are parallel and flat. The contact surface is uniform during the measurement.
In order to prevent the samples from sliding, the sample clamps should have a clamping force of not less than 690kPa. However, such pressure generally crosses the corrugated sample and should be indicated in the report.
2. Plastic membrane.
The glue film is round, from Elastic material composition. The glue membrane is firmly clamped, and its upper surface is about 5.5mm lower than the top surface of the loop. The glue film material and structure should make the glue film protruding the height of the sloping plate and the flexible resistance, that is, when the protruding height is 10mm, the resistance range of its resistance is (170 ~ 220) KPA; when the resistance range is 18mm, the range of resistance range For (250 ~ 350) KPA.
The test report needs to include the following:
1. This national standard number;
2. Types and specifications of samples;
3. The standard used in the test;
4. The atmospheric conditions of the test site;5. The name and model of the test instrument used, the holding force used;
6. The average value of the front and back of the brokenness retains three -bit effective numbers;
7. Test date, place, test personnel, etc.
