符合 JIS K 6253 規範，用於硫化橡膠或熱塑性橡膠的硬度測定。Type A適用於中等硬度的橡膠，Type D適用於硬質橡膠，軟質橡膠則用Type E（ISO7619的名稱為AO）。TYPE D是TYPE A測定值達90以上的硬質橡膠用，TYPE E是TYPE A測定值20以下的軟質橡膠適用。Type A 的GS-719N也適用於 JIS A 1108 "混凝土的壓縮試驗方法"定義抗壓強度的試驗方法。

		This is durometer which was developed to comply with JIS K 6253 (new JIS) ruled in 1993 to confirm ISO ( International Organization of Standard ). It consists of 3 types of durometer such as Type A for medium stiffness, Type D for high hardness and Type D for low hardness. Type A which is main type tends to indicate higher figure by 1 or 2 points compared with conventional A hardness measurement. Type D is suitable for hard rubber of which measured figure by Type A 90 and above and Type E is suitable for soft rubber of which measured figure is below 20.
