Generally, the inspection of insulating rubber sheet is carried out by third-party organizations, which are also divided into a variety of organizations. Generally, only reliable inspection organizations can carry out the inspection report.
General insulation rubber plate test report items include:
1. Shape and specification of insulating rubber sheet;
2. Strength of insulating rubber sheet;
3. The tensile strength and elongation at break of insulating rubber sheet;
4. The elongation of insulating rubber sheet was 150%;
5. The reduction rate of tensile strength of insulation rubber sheet under warm air embrittlement (70 degrees * 72h) was higher than that of the control;
6. Water absorption capacity of insulating rubber sheet;
7. The insulation characteristic test of insulating rubber sheet includes working voltage resistance test and breakdown field strength test.
Generally, the instruments and equipment used in the whole process of detection are: complete set of DC test transformer equipment; High pressure test control panel; AC / DC power data sheet; High and low temperature test alternating environment test chamber; Electric power engineering safety tools physical performance tester; Developing machine; Barbell type 1 indentation machine; Automatic slicer for rubber and plastic products test; Coating thickness gauge; Rubber hardness tester; Aging test chamber; Electronic analytical balance, etc;
It can be seen from the above inspection items and inspection machines and equipment that the whole process of inspection is very careful. If there is a reliable inspection report for insulating rubber sheet, then generally speaking, there is no problem. Naturally, this refers to a reliable testing organization, which is more standardized and prevents malpractice.
If there is a test report, then it is confirmed that the insulating rubber sheet manufacturer has the ability to produce and manufacture in line with the standards and specifications. In the production and manufacture of insulating rubber sheet, it is unlikely that there are no problems at every stage. A careless, a difference is likely to cause the insulation rubber pad commodity compression unqualified.
