The standard ISO/IEC 17025 does not specify in clause 7.8 if it possible to issue more than one test report following a single test.
This happens if one or more customer submits a joint test request, (e.g., in order to reduce the costs of expensive tests) but asking then to have, for each of the customer, a separate test report.
So, is it possible to issue separate test reports for the different customers, having conducted a single test, and under which conditions?
Please, consider that there are interpretation documents, issued by European Laboratory association (EGOLF) where this is considered acceptable and regulated
Clause 7.8.2.1 of EN ISO/IEC 17025:2017 requires reports to contain information to minimize any possibility of misunderstanding or misuse of results.
For this reason, when reporting results from a joint request to mutliple customers, it can be regarded as useful to ensure that:
– each receiver obtains an identical »original« copy of the report, containing a statement regarding the joint ownership/request and including a clear, transparent disclosure of the identification of all joint sponsors involved and the details regarding the specimen/item/componens tested.
– when an additional, separate individual report is issued to a specific sponsor/customer, such report should contain a reference to such »original« report and a clear indication of the item/object the reported results are relating to.
