标准摘要
[中文适用范围]： 本文件规定了测定硫化或热塑性橡胶辊套表观硬度的方法，以普西和琼斯压痕值表示。 Pusey and Jones 塑性计装置用于测量压头在指定力作用下压入橡胶表面的深度。 压痕值与国际橡胶硬度测试方法 ISO 48-2 测量的值不同，因为在该方法中，紧邻压头的橡胶被预压缩。 Pusey 和 Jones 压痕值是硬度的倒数测量值，即橡胶越硬，Pusey 和 Jones 压痕值越低。 [外文原描述]： This document 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 is not the same as that measured by the international rubber hardness test method ISO 48-2, 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.
