EUROLAB laboratory provides testing and compliance services within the scope of ISO 48-2 standard. This standard specifies four methods (standard hardness methods) for determining the hardness of vulcanized or thermoplastic rubbers on flat surfaces and four methods (apparent hardness methods) for determining the apparent hardness of curved surfaces.
Hardness is expressed in international rubber hardness grades (IRHD). The methods cover the hardness range of 10 IRHD to 100 IRHD.
These methods differ mainly in the diameter of the scoring ball and the magnitude of the scoring force; they are chosen to suit the particular application.
This standard specifies the following four methods for determining standard hardness.
This standard also specifies four methods for determining the apparent hardness of curved surfaces, CN, CH, CL and CM. These methods are modifications of the N, H, L, and M methods, respectively, and are used when the rubber surface being tested is curved.
