What is BS EN ISO 3992:2013?

BS EN ISO 3992:2013 is a technical standard that provides guidelines and requirements for the calibration and verification of coordinate measuring machines (CMMs). CMMs are devices used to measure the geometrical characteristics of an object with precise accuracy. This standard specifies the necessary procedures and tests to ensure the proper functioning and accuracy of CMMs.

The Importance of Calibration and Verification

Calibration and verification of CMMs are crucial to ensure accurate and reliable measurement results. Over time, factors such as wear and tear, temperature changes, and environmental conditions can affect the performance and accuracy of CMMs. Calibration involves comparing the measurements taken by the CMM with a known standard to determine any deviations or errors. Verification, on the other hand, assesses the overall performance of the CMM against specified requirements.

Key Requirements of BS EN ISO 3992:2013

This standard outlines several key requirements for the calibration and verification of CMMs. These include:

Environmental Conditions: The CMM should be operated in a controlled environment with specified temperature, humidity, and vibration levels to minimize any external influences on the measurements.

Initialization: The CMM must be correctly initialized before taking any measurements to ensure accurate readings.

Measurement Uncertainty: The standard defines procedures for estimating and documenting the uncertainty associated with the measurements taken by the CMM.

Testing Methods: It specifies various testing methods to determine the performance characteristics of the CMM, including length measurement, probing error, and positioning accuracy.

Reporting: The standard also provides guidelines for reporting the calibration and verification results, ensuring clear documentation of the CMM's performance.

Benefits of Adhering to BS EN ISO 3992:2013

Adhering to the requirements of BS EN ISO 3992:2013 brings several benefits to organizations that use CMMs. Firstly, it ensures the accuracy and reliability of measurement results, reducing the risk of errors or discrepancies. This is particularly critical in industries where precision measurements are vital, such as aerospace, automotive, and manufacturing.

Furthermore, following this standard facilitates traceability, allowing organizations to demonstrate compliance with international quality standards. It enhances customer confidence in the organization's products or services, as they can be assured of precise and consistent measurements.

In conclusion, BS EN ISO 3992:2013 plays a significant role in setting the guidelines and requirements for the calibration and verification of CMMs. Compliance with this standard not only improves the accuracy and reliability of measurement results but also enhances the organization's overall quality management system.
