This standard provides a specific Shore (P&J) hardness method for determining the apparent hardness of rubber-covered rollers. It is primarily applicable to rollers covered with vulcanized or thermoplastic rubber and aims to measure the depth of indentation formed by the indenter pressing into the rubber surface under a specified pressure. The core instrument of this method is the Shore (P&J) hardness tester. The measured value is an inverse hardness indicator, meaning that the harder the rubber material, the lower the measured indentation value. This differs from the measurement principle of international rubber hardness methods, such as ISO 48-2. This standard is identical to the international standard ISO 48-8:2018.
