软管或实心盘的压缩装置

[中文适用范围]： 本 SAE 推荐做法用于确定固定夹下的发动机冷却液软管可能出现的压缩形变。它试图重现由软管壁上的夹子造成的压痕类型。通过这种方法测量的过度压缩形变将表明软管最终可能导致冷却剂通过使用中的夹具泄漏。已发现该方法可在 25% 至 50% 初始压缩范围内提供可重复的结果。 [外文原描述]： This SAE Recommended Practice is used for establishing the compression set that could be expected to occur with a thermoset elastomeric hose under securing clamps. It seeks to reproduce the type of indentation caused by the clamps in the wall of a hose. An excessive compression set measured by this method may indicate a hose that could eventually allow leakage of fluid or gas past the clamps in service.Cross Reference: ASTMD3767,ASTME145
