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.

Guidance appears in italic typeface within a box after the appropriate requirement paragraph. To view the full content, you will need to purchase the standard by clicking on the “Buy” button.
Opinions and Interpretations The allows for opinions and interpretations to be documented on a test report. Organization When a calibration laboratory is part of an organization that performs other functions, both standards require that there be a separation between the additional activities of the organization and the calibration lab. Under the Z, calibrations are validated through methods of internal quality control. There is a great deal of richness in the ISO family of documents and it is a shame for users to not know about and take advantage of the full range of possibilities.
Personnel The Z requires sufficient laboratory personnel with the necessary technical and educational requirements for their assigned duties. The focuses on the competency of the legally responsible bodies providing test and calibration services. And detailed records must be maintained through the entire process.
If international customers 10012-11 such requirements, they are not covered by thebut rather by ISO While the scope of both documents includes language that can perhaps cause confusion, what follows is the salient text from both that illuminates the difference between the two. Intermediate measures of the precision of a standard measurement method. General principles and definitions.
The Z also requires statements of traceability on calibration reports. 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. Use in practice of accuracy values. Measurement Traceability The Z requires traceability of measurements to national standards, international standards, or intrinsic standards that have been compared to other cxlibration standards, particularly those of national labs.
An organization, for example, could have a quality management systems that is certified to Isk Management Review An annual management review of the quality system is required by Z For more information on traceability, refer to the NIST website: Metrology ProgramQuality Progress. The was written to ieo 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The requires job descriptions for managerial, technical, and key personnel and encourages job descriptions for personnel involved in calibration or testing. Measuring equipment usually has several metrological characteristics. Legal Responsibility requires laboratories caliibration be legally responsible entities.
The requires a comprehensive uncertainty analysis for all calibrations under the philosophy that traceability of a calibratiom cannot be established without knowing the expanded uncertainty. Corrective and Preventive Actions The Z contains a general statement about procedures for corrective actions regarding measurement discrepancies or departures from documented procedures.
The laboratory and the client must fully understand and agree on the calibration or testing services provided. Laboratories meeting the calibtation of the Z do not necessarily meet the requirements of the and some accrediting bodies no longer state accreditation to Z on accreditation certificates.
If customers choose to add these elements to their requirements, their scope of accreditation can reflect compliance to the Z Part 1. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. From the scope of ISO ISO focuses on the requirements of the measurement management system.
Undermanagement review is completed according to a predetermined schedule, which does not have to be annual. Laboratories need to fully investigate these two standards and come to an understanding of their differences. callibration
It specifies the quality management requirements 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. Note 5 to entry: If you want to generate true confidence of measurement that your customers and AB appreciate, then of all of those standards, I recommend Z Any changes or improvements to the system should be addressed in the review.
Only the covers both calibration and testing services.
Relevant training records of calibration personnel shall be available to the laboratory. References to this International Standard can be made. Management shall formulate goals for training, education, and skills. The requires laboratories to establish and maintain a procedure for quality and technical records.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. The requirements appear in normal typeface. Technical Records The goal of the record system identified in the Z is to retain sufficient information to repeat a calibration under identical conditions.
Correctly applied measurement, wherever and however it occurs, is an essential element of a successful business QMS.
However if you are performing calibrations for other companies, and you are not accredited yet, I strongly recommend Z
