Which of the following ISO standards is focused on general requirements for testing and calibration laboratories?

The correct answer focuses on the ISO/IEC 17025:2005 standard, which specifically outlines the general requirements for the competence of testing and calibration laboratories. This standard is essential for laboratories as it demonstrates their ability to produce accurate and reliable results, ensuring that they operate within a framework of quality management and technical proficiency.

ISO/IEC 17025 covers aspects such as quality management systems, technical competence, and the validity of results, which are critical for laboratories involved in testing and calibration processes. It ensures that laboratories meet quality standards that enable them to provide credible testing and calibration services, which is crucial for regulatory compliance and maintaining industry standards.

In contrast, ISO 15189:2007 is specifically tailored for medical laboratories, emphasizing the quality and competence related to medical testing rather than general laboratory requirements. ISO 9001:2000 is a broader quality management system standard that applies to various organizations but does not focus specifically on laboratories or their testing and calibration processes. ISO 14001:2015 relates to environmental management systems, addressing the environmental impact of an organization's operations rather than the technical and quality aspects relevant to testing and calibration labs.

Therefore, ISO/IEC 17025:2005 is the standard that directly addresses the general requirements essential for
