L-A-B's Long Authors Article on Validating Methods, Procedures, and Instructions for ISO/IEC 17025

The latest issue of Quality Digest features an article on "Validating Methods, Procedures, and Instructions for ISO/IEC 17025" by Randy Long, Calibration Program Manager with the Laboratory Accreditation Bureau (L-A-B), which was recently acquired by ANAB. An L-A-B study on noncompliances during ISO/IEC 17025 accreditation assessments found that the most cited clauses were found in section 5.4 (Methods and method validation) of the standard.

In the article, Long attempts to clarify the intent of section 5.4 and help labs better select, validate, and manage their methods, procedures, and instructions. Uncertainty measurement and how it relates to test or calibration measurements and data control are also examined in the article.
