When no such standards exist, the basis used for calibration or verification should be recorded. The instrument used as a reference should be traceable to an instrument that is calibrated to your country’s National Standard for example, the UK National Standard (UKAS) or to the US National Institute of Standards and Technology (NIST). However, accuracy ratio of 3:1 is acceptable by most certification bodies. As a rule of thumb, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. This activity requires that a comparison is made between a known reference measurement (the standard equipment), and the measurement using your instrument (test instrument).
The process of calibration involves configuring an instrument to provide sample measurement results within an acceptable range. What is calibration?Ĭalibration of instruments is one of the primary processes used to maintain instrument accuracy. Therefore, a corrective procedure is required to maintain accuracy. Factors such as electrical and mechanical shocks or environmental conditions like temperature and humidity may affect the accuracy of measurement. Accuracy of all instruments decays with usage and wear and tear of the instruments. The importance of correct measurements from these instruments cannot be understated, since it can lead to a faulty product. The manufacture of medical devices makes use of various types of equipment and measuring instruments ranging from simple temperature sensors, weighing balances, pressure gauges, micrometers for measuring dimensions, to more complex ones, including digital instruments.

Annex A provides guidance on the use of this document and Annex B gives examples of scenarios in water efficiency.Manufacturing medical devices is a highly complex process, and calibration requirements according to ISO 13485 mean high precision and close monitoring. NOTE 4 Guidance in the annexes provides additional practical information to support implementation.
For utilizing water reuse systems, ISO/TC 282 documents can be referred to as guidelines. NOTE 3 ?Reuse' includes recycling of, for example, process water or grey water. NOTE 2 ?Replace' includes substitution of drinking water with reclaimed water, sea water and rainwater wherever feasible. NOTE 1 ?Reduce' includes the use of water-efficient fittings and equipment and, for example, putting in place a proper monitoring system for usage and leak detection. It includes monitoring, measurement, documentation, reporting, design and procurement practices for equipment, systems, processes and personnel training that contribute to water efficiency management. This document specifies requirements and contains guidance for its use regarding organizational water use. This document is applicable to any organization that wishes to:Ī) achieve the efficient use of water through the ?reduce, replace or reuse' approach ī) establish, implement and maintain water efficiency It is applicable to organizations of all types and sizes that use water. This document specifies requirements and contains guidance for its use in establishing, implementing and maintaining a water efficiency management system.
