This post introduces step-by-step the different activities that are required to satisfy (in an efficient manner) ISO 9001 and AS 9100 calibration requirements for control/measuring equipment used for product and process verification. One of the clauses in ISO 9000 requires that all persons using calibration equipment be adequately trained. By data, showing the capability of the personnel, procedure and equipment to achieve the claimed measurement uncertainty. The NIST quality system for measurement services is internationally recognized and meets the requirements of the International Committee for Weights and Measures (CIPM) Mutual Recognition Arrangement (MRA) for recognition of national measurement standards. This approach is practical, as the organizations own personnel need not undergo high-level metrology training, and it is cost-effective, as expensive, high-accuracy, measurement standards need not be maintained in-house, while the bulk of measuring equipment need not be submitted to costly external calibration. When an environmental sample measurement falls outside the calibration range, the instrument must be re-calibrated to bracket the new range before continuing measurements. : pyrometry, process equipment, ) and keep the rest (and the vast majority) in paper format. For more than 50 years, NIST has developed and distributed Standard Reference Data. Make the system so easy that anyone can support this activity in case of absence or leave. As a rule of thumb, its best if you make a list with the name and description of any equipment used by your organization. This way, only authorized personnel can access these items when needed for calibrating equipment during operations hours. These materials are used to perform instrument calibrations in units as part of overall quality assurance programs, to verify the accuracy of specific measurements and to support the development of new measurement methods.

Manufacturing medical devices is a highly complex process, and calibration requirements according to ISO 13485 mean high precision and close monitoring. The foundations that we discussed so far are the most critical part of the system. (Note: Clause numbers below are from ISO 9001:2008.). Instead of trying to create everything you need to follow this process from scratch, use ours. A free publication about ISO/IEC 17025, and how it can help testing and calibration laboratories demonstrate their capacity to deliver trusted results. Support can be provided by email after purchase. Calibration Technician. If not done yet, organize them in one location (a shared drive or physical folder).There is no requirement to have all the reports scanned and available in electronic format. Steel Measuring Tapes Calibration Applicable Standards: ISO 8322-2 1999 Building construction - Measuring instruments - Procedures for determining accuracy in use - Part 2 Measuring tapes, or . 1m (0,001mm) ins. For example, people may complain about the software system to track calibration due dates, or the sticker attached to every tool gets worn too easily, or the current system led to AS 9100 findings in the past. Calibration services allow customers to achieve the highest quality in their measurement systems, and to provide assurance in their results, by communicating the NIST measurement results for carefully selected instruments and artifacts. In general, the Quality Manager is required to: All employees and Process Owners are required to: For example, suppose you need a piece of equipment used across your organization calibrated. This means that you can verify a measuring instrument without calibrating it. As RTDs falling within these limits are acceptable to the organization, the single-point calibration/verification demonstrating compliance at 0 C (difference < 0.3 C, with expanded uncertainty of 0.3 C) is judged to be sufficient to control temperature measurement accuracy over the full range of operation. of the principles of measurement and calibration of measuring instruments falling into the following fields; Length,Angle, Mass, Pressure, Force, Temperature and AC/DC Electrical quantities. For example, it is probably not useful to install a temperature sensor accurate to 0.1 C if the temperature controller has a cycle of 5 C; a sensor accurate to 1 C or 1.5 C would probably do. Now that you have put in place the skeleton of your system, you can make the ball rolling. I hope the above ideas will help you design a system that meets AS 9100 calibration requirements as well as your stakeholders expectations. The junior staff members then perform in-house calibration of the organizations working RTDs at 0 C every three months (the interval being chosen to adequately manage the risk of measurement error) and record the results in a controlled document, with control limits of 0.3 C being imposed. Our ISO Auditors and Quality Manager Trainers have been in this industry for years, and since 2002 weve been providing thousands of small businesses and large corporations with the tools they need to get certified. What good is measuring equipment if its not measuring correctly, after all? The calibrated equipment process is considered a crucial procedure in quality management. Similarly, validated, automated machine tools such as lathes, printed-circuit drills, and component inserters can be monitored and maintained by conducting a first and last-piece inspection of representative product lots to assure accuracy. Calibration is defined at Section 2.3.9 as the operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncer, tainties provided by measurement standards and corresponding indications with associated measurement uncertainties . Select suitable equipment to perform the required measurements with accuracy and precision, Extend the control of inspection and test equipment to all approved suppliers where applicable, Ensure inspection and test equipment cannot be used if they are not registered and calibrated, Ensure inspection and test equipment is calibrated in a suitable environment, Control all measurement, calibration and maintenance activities, Check that inspection and test equipment is not damaged and is fit for purpose. (In other words, a working RTD passes if it reads between -0.3 C and +0.3 C at the ice point.) They: NISTs portfolio of services for measurements, standards, and legal metrology provides solutions that ensure measurement traceability, enable quality assurance, and harmonize documentary standards and regulatory practices. Any use, including reproduction requires our written permission. For example, ISO 9001 states that the Quality Manager should administer the calibration procedure.
