The standard ISO/IEC 17025 specifies in clause 7.8.8.1 that if it is necessary to change, amend or re-issue an already issued test report, any change of information shall be clearly identified and, where appropriate, the reason of such modification shall be included in the report (“When an issued report needs to be changed, amended or re-issued, any change of information shall be clearly identified and, where appropriate, the reason for the change included in the report.”).
Nevertheless, the standard does not specify which reasons are “acceptable” to reissue a test report.
Even on the light of document EA 2014 (33) 31 with respect to reissuance of test reports when the trade name / trademark of the tested product has changed, it is noted in this resolution just, in which cases test reports “shall” be reissued (“Test reports shall be reissued only for the correction of errors and the inclusion of omitted data available at the time of test.”)
Does this resolution limits the reasons for reissue the test report “correction of errors” and the “the inclusion of omitted data available at the time of test” or which reason can be considered as proper for the reissue of a test report?
Resolution EA 2014 (33) 31 is superseded by TMB Resolution 2021 (03) 01, which includes a reference to the relevant clause 7.8.8 of EN ISO/IEC 17025 :2017.
This resolution does not limit the possible reasons for reissuance of test reports, and other considerations regarding the reasons for reissuance of test reports are possible in the light of clause 7.8.8.1 in EN ISO/IEC 17025:2017.
It should be noted that any change, amendment or reissuance of reports requested by the customer shall not impact the integrity of the laboratory and any amendments to the reported results for whatever reason must be related to the item tested, calibrated or sampled, e.g. no data can be added / changed if not related to the actual item detailed in the initial report.
