标题: [提问]BSI元器件证书的有效期问题 [打印本页] 作者: 伯乐跑车 时间: 2011-10-19 00:04 标题: [提问]BSI元器件证书的有效期问题 BSI插头等的证书上没有明确的失效日期,一般是多少年?证书上只有这么一句话:The approval remains in force concurrent with the BSI certification year of May 1-Apr 30 and will automatically lapse at midnight 30 April following the date of issur of this schedule.是否可以理解为只有一年有效期?每年都要更新?
