According to ISO/IEC 17025 principles of corrective action, what is the most critical initial step the laboratory must take?

Accepted Answer

Evaluate the significance of the nonconforming work and its potential impact on previous concrete strength test results.

Answer

Immediately recalibrate the load cell and reverify the compression machines.

Answer

Discipline the technician responsible for using the out-of-date load cell.

Answer

Update the internal audit schedule to increase the frequency of equipment checks.

Question 2

Question 3

A technician in a CCIL asphalt laboratory is preparing a test report for a client that will be used to determine compliance with a municipal specification. According to ISO/IEC 17025, when must the report include a statement on the measurement uncertainty?

Accepted Answer

When it is relevant to the validity or application of the test results, or when the customer requests it. [4, 10]

Answer

Answer

Only when the measurement uncertainty value exceeds 5% of the reported result.

Answer

It is never a mandatory requirement for standard test methods like those used in CCIL labs.

Question 4

In the context of a materials testing laboratory accredited to ISO/IEC 17025, which of the following best describes the principle of 'metrological traceability'?

Accepted Answer

An unbroken chain of calibrations linking a measurement result to a national or international standard (SI unit), where the uncertainty of each step is documented. [6, 28]

Answer

The ability to track a physical sample from the moment of receipt through all testing stages to the final archival.

Answer

The requirement that all test procedures and laboratory documents are controlled and have a unique version number.

Answer

The process of keeping all original test records and reports for a minimum period of five years.

Question 5

A laboratory's management review, a mandatory requirement of ISO/IEC 17025, must include several key inputs to be effective. Which of the following is a required input for this review?

Accepted Answer

The results of internal audits, corrective actions, and proficiency testing activities. [9]

Answer

A forecast of the laboratory's profitability for the next fiscal year.

Answer

A summary of marketing activities and new client acquisitions.

Answer

A comparison of technician salaries against industry benchmarks.

Question 6

A site manager for a major construction project, the lab's largest client, disputes a set of low aggregate gradation results.

Which fundamental principle of ISO/IEC 17025 would be most directly compromised if the lab supervisor agrees to alter the report?

Accepted Answer

Impartiality

Answer

Confidentiality

Answer

Document Control

Answer
