这是SHOEI官网上的描述:
Helmet ReplacementUltimately, the useful service life of a safety helmet is dependent on the intensity and frequency of its use. Helmet replacement is recommended even if only one of the under-mentioned points applies: 使用的强度和频率决定头盔的服务寿命。发生以下情况之时,建议更换头盔: 1. The helmet was subjected to an impact. 头盔摔过了
2. The comfort padding or the retention system has become loose due to heavy use or display signs of deterioration. Test: with the retention system fastened, the helmet turns to the side when you gently shake your head.
由于用得比较狠,内垫或紧固系统变松了,或者出现衰退迹象。测试标准:如果紧固系统已经上紧,轻轻晃动头,头盔可以向边上转动
3. The EPS liner has come away from the helmet shell.
EPS衬层脱落
4. The EPS liner shows signs of wear and is beginning to break up, or if it has been exposed to heat or a solvent and has melted. There are indentations in the EPS liner and/or white scratches can be seen on surfaces with black paint.
EPS层衬层出现磨损并且开始解体,或者曾接触过高温或溶剂且被融化。EPS有被挤出坑或者黑色涂层表面出现了白色的划伤
5. Even if none of these is applied, we, SHOEI, recommend replacement in 5 years after it's first purchased at retail.
即使上述情况都未发来,SHOEI建议从零售商购入的5年后更换
