Equipment calibration certificate/test report

You asked

according to iso 17025:2017, who in the laboratory is responsible for: 1- reviewing equipment calibration certificates?

I assume you are referring to a testing not calibration laboratory, meaning that “reviewing equipment calibration certificates” refers to review of calibration certificates supplied to you by an accredited calibration laboratory.

The person responsible for the performance of test methods influenced by the calibrated apparatus is responsible, or alternatively the technical or laboratory manager. All personnel using the calibrated apparatus should however understand the certificate and know how the result outcome (performance) could impact on the validity of the performed test methods. The review of the certificate should ensure a) the supplier is / was competent,  b) the required metrological traceability is evident (traceable to International standards),  c) the necessary uncertainty and performance parameters are reported suitably to make an objective decision on the performance and risks and d) the specification and measured performance is acceptable to use the apparatus for the purpose intended.

according to iso 17025:2017, who in the laboratory is responsible for: 2- signing of test report?"

Typically an appointed and competent “signatory” is assessed by the laboratory’s accreditation body and they take responsibility for the technical validity of results. Often the laboratory manager will co-sign a test report, taking overall responsibility for the approval of a report to go to a customer. The laboratory’ s quality assurance process should specify this, meaning what objective checks and responsibility does a “signature” indicate. A laboratory should also document responsibility for confirming the validity of the results after evaluating control parameters such as internal and external quality control monitoring and data transcription (integrity). Who this is, will depend on the organisational structure.

The following Academy ISO 17025 document template: Testing Report Procedure may be of interest, available at https://advisera.com/17025academy/documentation/testing-report-procedure/ It outlines the requirements for writing test reports, to meet the requirements of ISO/IEC 17025:2017 for reporting test results.
