按照《认证机构管理办法》规定，证书样式必须在国家认监委备案，如果不带CNAS和IAF标志的证书的样式与备案一致,证书是有效的。但是，如果你的客户需要CNAS和IAF标志的证书，这张不带CNAS和IAF标志的证书就不会被你的客户认可。
In accordance with the "provisions" managementcertification, certificate must be in the CNCA record, if the style without CNAS and IAF logo Certificate in accordance with the registration, certificate is valid. However, if your clients need CNAS and IAF mark certification, this without the CNAS and the IAF logo certification will not be your customer recognition.
认证证书带CNAS标志是说明认证机构的相应小类获得了CNAS的认可，而带IAF标志说明是CNAS和IAF基于一些认证范畴达成了共识并且进行了互认。

现在国内的OHSAS18000基本上就属于没有互认，所以如果是只拿CNAS认可的国内认证机构，发放的18000的证书基本上都只有CNAS标志，没有IAF标志。而如果认证证书没有CNAS并IAF标志的，应该至少有一个机构的标志，说明此证书发放的是带认证机构标志的认证证书。
