A customer requests that a laboratory use their (the customer's) specified test method rather than the laboratory's standard method. Under ISO 17025, the laboratory should:

Accepted Answer

Evaluate whether the customer method is appropriate and inform the customer of any concerns before proceeding

Answer

The laboratory should assess the customer's method for appropriateness and communicate any concerns or limitations to the customer before use.

Question 3

ISO 17025 requires laboratories to define criteria for reviewing requests, tenders, and contracts. What is the primary purpose of this review?

Accepted Answer

To ensure the laboratory has the capability, resources, and method to meet customer requirements before committing

Answer

Contract review ensures the laboratory can actually meet customer requirements in terms of capability, resources, and method before accepting work.

Question 4

When reporting measurement results with expanded uncertainty, what coverage factor (k) is most commonly used to express uncertainty at approximately 95% confidence?

Accepted Answer

k = 2

Answer

A coverage factor of k = 2 is most commonly used, providing approximately 95% confidence for a normal distribution.

Question 5

According to ISO 17025, how should a laboratory handle situations where a customer requests that test results be reported without measurement uncertainty?

Accepted Answer

The laboratory may omit uncertainty if the customer requests it and the reason for exclusion is stated in the report
