F 右下方的数字为 H0的百分数，与其对应 P 右下方亦标有相同数字。7 检查与试验方法7.1 外观弹簧外观的检查采用目测或用 5 倍放大镜进行。7.2 硬度按 GB 230 的规定检验。JB/T 66531993157.3 弹簧特性弹簧特性的测定应按表 5表 8 尺寸表的规定值在弹簧试验机上进行。7.4 永久变形将弹簧成品用表 5表 8 尺寸表的规定值负荷连续压缩 10 次后测量其 H0的变化值。7.5 自由高度用通用或专用量具测量弹簧的最高点。当其自重影响自由高度时，应置水平方向测量。7.6 弹簧直径用通用或专用量具测量。7.7 垂直度用二级精度平板、三级精度宽座角尺和 100m 塞尺测量，在无负荷状态下，将被测弹簧竖直放在平板上，贴靠宽座角尺，自转一周，同时用塞尺测量取大值；再按此法测量弹簧的另一端面，将两端面垂直度误差中的较大值作为弹簧的垂直度误差，如图 2。图 28 检验规则8.1 弹簧的验收抽样检查按 GB 1239.5 的规定。8.2 弹簧其他项目的检验应符合本标准第 5 章技术要求的规定。9 标记弹簧的标记由类型代号、窝孔直径、自由高度及本标准编号组成。规定如下：类型代号窝孔直径 自由高度标准编号Dmin H0JB/T 6653例：轻型 Dmin=25 mm，H0=50 mm 的弹簧：弹簧 L2550 JB/T 6653 重型 Dmin=50
