What is the ISO standard for calibration of equipment?
ISO/IEC 17025
ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories is the main ISO standard used by testing and calibration laboratories. In most countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent.
What are the calibration requirements?
Calibration requirements include the need to… Establish and maintain documented procedures. Determine measurements to be made and accuracy required. Select an appropriate measurement instrument capable of measurement accuracy and precision. Identify and define measurement instrument for calibration.
How often should measuring equipment be calibrated using ISO 9001?
Instruments Used for Measurement To begin, the instruments that are used for measuring resources must always be calibrated in intervals before being used, while following the specified standards in doing so.
What is calibration according to ISO?
The process of calibration involves configuring an instrument to provide sample measurement results within an acceptable range. This activity requires that a comparison is made between a known reference measurement (the standard equipment), and the measurement using your instrument (test instrument).
How often should NDT equipment be calibrated?
Depending on their usage, you may have to calibrate equipment on a monthly, quarterly or semiannually basis.
When should an instrument be calibrated?
WIKA’s recommendation for a calibration check and re-certification is once every 12 months. However, the frequency for a calibration check of a measuring instrument depends on many factors: What are the operating conditions of the instrument?
What is calibration procedure?
A calibration procedure is a controlled document that provides a validated method for evaluating and verifying the essential performance characteristics, specifications, or tolerances for a model of measuring or testing equipment.
What are the requirements for calibration in ISO 9001?
Clause 7.1.5 of ISO 9001:2015 defines the requirements for calibration in ISO 9001 and is called Monitoring and Measuring Resources for ISO 9001. This standard does not provide the actual procedure for calibration but outlines the requirements an organization must follow. Every organization can choose its way of fulfilling these requirements.
Do you have to calibrate an instrument before using it?
Calibration is necessary before you can use a new instrument. It is not professional to start using instruments before calibration. It sometimes happens when there is urgency in a process, and since calibration activity takes time, the concerned people start using it without calibration.
When do you need to use ISO 17025 calibration?
In short, if any equipment (and its associated measurements) requires metrological traceability, then measurement uncertainty must be estimated for that equipment regardless of if it is within the ISO/IEC 17025 scope of accreditation or not.

How are master gauges and measuring equipment calibrated?
Most organizations adopt a “hybrid” approach: Master gauges, and equipment requiring complex calibration procedures, are calibrated by an external, ISO 17025-accredited, calibration laboratory. Low-accuracy, simple (“factory floor”) measuring equipment is calibrated in-house.
