Inspection standard of insulating rubber board :(take 8mm insulating rubber board as an example)
1. Appearance: 

1) the depth and height of the mark do not exceed the thickness tolerance of the rubber plate

2) within one square meter, there shall be no more than 5 bubbles with an area less than 1cm, and the distance between any two bubbles shall be no less than 40mm.

3) the depth and length of impurities shall not exceed 1/6 of the thickness of the rubber plate

4) uneven edges or sea-level width shall not exceed 10mm, and the length shall not exceed 1/10 of the total length of the rubber plate

5) no cracks

2. Hardness (shao er A) : 55-70
