跟大家分享 O型圈 硬度计 是如何测量的: After many years of experience, Hefei Boyi will share with you how the O-ring hardness tester measures:

First, the main purpose of LA-X Shore hardness tester :
Applicable to the determination of the hardness of ordinary vulcanized rubber and its similar thin samples (thickness of 1.5mm or more) and thin rubber O-rings, measuring rubber hardness of Shore A hardness 20HA (degrees)-90HA (degrees).
Note: The thickness of the rubber sample is at least 1.5 mm. If the thickness of the rubber sample is less than 1.5 mm, no more than 3 layers can be used. The thickness of each layer is not less than 0.5 mm. The results of the samples are not necessarily consistent.

Selection Guide:
LX-A type Shore hardness tester , suitable for the ordinary hardness range, when less than 20HA, choose LX-A type hardness tester, when above 90HA, choose LX-D type hardness tester
LX-D type hardness tester, suitable for high hardness range, LX-A type hardness tester is used when it is lower than 20HD
Third, the implementation standards:
It implements China's GB / T 531.1-2008, "Test Method for Indentation Hardness of Vulcanized Rubber or Thermoplastic Rubber Part 1: Shore Hardness Test (Shore Hardness)", which is the national standard equivalent to the international standard ISO 7619-1-2004
