ISO 48:2007 硫化橡胶或热塑性橡胶 硬度的测定（硬度在10IRHD和100IRHD之间）

标准编号：ISO 48:2007

中文名称：硫化橡胶或热塑性橡胶 硬度的测定（硬度在10IRHD和100IRHD之间）

英文名称：Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and 100 IRHD)

标准范围

ISO 48:2007规定了四种测定平面硫化橡胶或热塑性橡胶硬度的方法（标准硬度法）和四种测定曲面表观硬度的方法（表观硬度法）。硬度以国际橡胶硬度（IRHD）表示。这些方法的硬度范围从10 IRHD到100 IRHD。这些方法的主要区别在于压痕球的直径和压痕力的大小，选择这些方法是为了适合特定的应用。ISO 7619-2中描述了用袖珍硬度计测定硬度。ISO 7267的各个部分分别讨论了胶辊表观硬度的测定。

ISO 48:2007 specifies 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). The methods cover the hardness range from 10 IRHD to 100 IRHD.The methods differ primarily in the diameter of the indenting ball and the magnitude of the indenting force, these being chosen to suit the particular application.The determination of hardness by a pocket hardness meter is described in ISO 7619？2.Determination of the apparent hardness of rubber-covered rollers is dealt with separately in the various parts of ISO 7267.
