ISO/IEC General requirements for the competence of for the competence of testing and calibration laboratories, and I would like. We should let ISO be guidance for the users of measuring equipment and let ISO G25//Z be for the calibration labs. ISO/IEC and the relevant requirements for calibration and testing uncertainties of measurement, to calibrate measuring and test equipment, to.

References to this International Standard can be made.

Note 5 to entry: In the remainder of this article, we outline some of the importance differences between the two major standards. Use in practice of accuracy values. It specifies the quality management cslibration of a measurement management system that can be used by an organization performing measurements as part of the overall management system, and to ensure metrological requirements are met. ISO defines requirements for entire quality management system that can be accredited.

The Z requires findings and corrective actions resulting from audits to be documented and that the individual responsible for quality should ensure that corrective actions are completed on time. Introduction An effective measurement management system ensures that measuring equipment and measurement processes are fit for their intended use and isl important in achieving product quality objectives and managing the risk of incorrect measurement results.

Interested parties can agree calkbration use this International Standard as an isoo for satisfying measurement management system requirements in certification activities. ISO describes the requirements for a quality management system that can be accredited a process comparable but different from certification.


It defines requirements relevant to the measurement management system in language that may illustrate interrelations to other parts of an overall quality management system.

Calibraion states that traceability shall be assured by the use of competent laboratories that demonstrate measurement capability and traceability. The was written to include the requirements for both calibration and testing laboratories by demonstrating that the laboratory operates in a technically competent manner under the confines of a documented quality system producing valid results.

Intermediate measures of the calibraton of a standard measurement method. The details the minimum elements of job descriptions and specifies that the quality manual contain the job descriptions for the technical manager and quality manager for the lab. If customers choose to add these elements to their requirements, their scope of accreditation can reflect compliance to the Z Part 1.

Difference Between ISO/IEC 17025 and ISO 10012

Note 3 to entry: Basic methods for the determination of repeatability and reproducibility of a standard measurement method. Metrological confirmation generally includes calibration and verification, any necessary adjustment or repair, and subsequent recalibration, comparison with the metrological requirements for the intended use of the equipment, as well as any required sealing and labelling.

Demonstration of the competency of the laboratory can be accomplished by accreditation or other means such as interlaboratory comparisons. The Z does not directly address opinions and interpretations.

Comparison of ANSI/NCSL Z to ISO/IEC

Training of personnel shall be documented and kept up-to-date. It also depends on the focus of your business. The philosophy of the is focused on providing competent measurement services with results that are traceable to appropriate standards.


From the scope of ISO Thehowever, requires a procedure for the review and retention of all records pertaining to requests, tenders, or contracts. ISO shall not be held responsible for identifying any or all such patent rights.

Root Cause Analysis Samples. Cause analysis, implementation, monitoring, and additional audits are specifically discussed. Metrological requirements are usually distinct from, and are not specified in, product requirements.

If you want to generate true confidence of measurement that your customers and AB appreciate, then of all of those standards, I recommend Z The client and the laboratory must agree upon the appropriate method of calibration. This is an issue of legal responsibility and accountability for the calibration work performed by the laboratory or organization.

While the Z does not specifically require traceability to International System of Units SI units, such traceability would be implied by traceability to national or international standards.

Only the covers both calibration and testing services. Personnel The Z requires sufficient laboratory personnel with the necessary technical and educational requirements for their assigned duties.

These bodies may be independent or part of a larger organization. The requirements for intended use include such considerations as range, resolution and maximum permissible errors.
