    Abstract - (Show below) - (Hide below)

    Describes four methods for the determination of the hardness of vulcanized or thermoplastic rubbers on flat surfaces (standard-hardness methods) and four methods for the determination of the apparent hardness of curved surfaces (apparent-hardness methods). The hardness is expressed in international rubber hardness degrees (IRHD) covering the hardness range from 10 IRHD to 100 IRHD.
