     GB5574-85中橡膠板代號表明辦法：
*位：橡膠板品種：1－一般橡膠板，2－耐酸堿橡膠板，3－耐油橡膠板，4－耐熱橡膠板。
第二位：橡膠板硬度10位數(shù)，如4604橡膠板的硬度代碼是6，硬度就為60±5紹氏度。
第三、四位：橡膠板的拉伸強度，如4604橡膠板三四位是04，拉伸強度就是４Mpa。
    GB/T5574-2008中橡膠板的表明辦法為：
*節(jié)：耐油性，A-不耐油，B-中等耐油，C-耐油；
第二節(jié)：橡膠板的拉伸強度的標稱值，單位MPa
第三節(jié)：拉斷伸長率的組別。近伸長率/100。
第四節(jié)：橡膠板硬度/10，參加H字母。
