The validity of a CB Report, please help to clarify!

Please help to clarify, how long is a CB report in valid?

Problem: recently, we provide a CB report (IEC60950) which is issued in 2004 to our client, but the client doubted that the CB report was invalid. How should I explain to my client?

一般測(cè)試報(bào)告的有效期為1年，應(yīng)在有效期內(nèi)針對(duì)市場(chǎng)情況轉(zhuǎn)相應(yīng)的認(rèn)證證書才劃算！

只要測(cè)試標(biāo)準(zhǔn)沒(méi)有更新，測(cè)試報(bào)告有效，你可以看看IEC 60950標(biāo)準(zhǔn)的前言，應(yīng)該有解析標(biāo)準(zhǔn)可能更新、終止的事宜。
