General Requirements

4.1 Impartiality

Impartiality is a major clause in ISO/IEC 17025. This clause addresses the risks associated with creating biased results. Under no circumstance is the lab allowed to let conflict of interest impact its results, and the lab must be committed to risk-based thinking when addressing impartiality.  In essence, there must not be any conflict of interest regarding the following:

  • commercial interest
  • financial interest
  • relationship interest

And the laboratory must identify risks to impartiality from:

  • activities
  • relationships
  • personal relationships

The lab must identify any risk to impartiality on an ongoing basis. If a risk or impartiality is identified, the lab must take corrective action and demonstrate how it has eliminated or minimized the risk.

4.2 Confidentiality
