I have a very important question related to ISO standard 17025-2017. An accredited laboratory having ISO standard 17025-2017, indicating in documentation that the CAB is not doing any sampling. Explain and justify to me how this lab is not applicable for the clause 7.3 of ISO standard 17025-2017.

If a laboratory (the Conformity Assessment Body - CAB) performs sampling at the source, e.g a factory or river, to collect a sample for testing; only then does clause 7.3 Sampling apply. Another way of putting it is a laboratory is not responsible for sampling if the sample is taken by another party and brought in or delivered for testing. That is, clause 7.3 does not apply. The other party could for example, be either the production department, researchers or other clients. Typically laboratories will state in the Quality Manual that Clause 7.3 requirements of ISO 17025 are not applicable as they do not perform sampling,

There may be certain situations, where it is necessary, to meet Clients purpose of the test, for the laboratory to provide sampling and transport instructions or guidance to assist the client present a more representative, stable sample. This is to ensure the sample result is more representative of the source as a whole (e.g a drinking water well). The client should also be informed as to what information to record, like date of sampling. This is crucial information for the interpretation of many results. Once the sample arrives at the laboratory any sample splitting, aliquoting or handling is covered other the other technical requirements, including clause 7.4 Handling of test or calibration items.
