标准范围

ISO 7267-3:2017规定了硫化橡胶或热塑性橡胶辊盖表观硬度的测定方法，表示为Pusey和Jones压痕值。Pusey和Jones塑性计装置用于测量压头在特定力下压入橡胶表面的深度。压痕值不应与国际橡胶硬度试验方法ISO 48[1]测量的硬度混淆，因为在该方法中，紧靠压头的橡胶是预压缩的。Pusey和Jones压痕值是硬度的反向测量，即橡胶越硬，Pusey和Jones压痕值越低。

ISO 7267-3:2017 specifies a method for the determination of the apparent hardness of vulcanized- or thermoplastic-rubber roller covers, expressed as the Pusey and Jones indentation value.The Pusey and Jones plastometer apparatus is used to measure the depth of indentation of an indentor under a specified force into the surface of the rubber. The indentation value should not be confused with hardness as measured by the international rubber hardness test method ISO 48,[1] since in this method the rubber immediately adjacent to the indentor is precompressed. The Pusey and Jones indentation value is an inverse measurement of hardness, i.e. the harder the rubber the lower the Pusey and Jones indentation value.
