What is BS EN ISO 6142:2014

The BS EN ISO 6142:2014 is a technical standard that provides guidelines for the preparation of calibration gas mixtures used in analytical laboratories and industrial applications. This standard specifies the requirements and procedures for the production of these mixtures, ensuring accuracy, reliability, and traceability in measurement results.

Importance of Calibration Gas Mixtures

Calibration gas mixtures are crucial in various industries where accurate measurement is essential. They are used to calibrate and verify the precision of analytical instruments such as gas chromatographs, mass spectrometers, and chemical sensors. These instruments require reliable calibration gases to ensure the accuracy of their measurements, which directly impact product quality, safety, and compliance with regulations.

Key Components of BS EN ISO 6142:2014

BS EN ISO 6142:2014 addresses several crucial aspects of producing calibration gas mixtures. Firstly, it establishes strict guidelines for the metrological traceability of reference gases, ensuring that the composition of the mixtures can be traced back to internationally recognized standards. This helps to minimize measurement uncertainties and provides confidence in the accuracy of results.

Secondly, the standard specifies methods for preparing gas mixtures using gravimetric, volumetric, or dynamic methods. These methods ensure that the concentration of each component in the mixture is accurately controlled, allowing for precise calibration of instruments. Additionally, the standard provides guidance on determining the uncertainty of the mixture's composition.

Quality Control and Certification

Another important aspect covered by BS EN ISO 6142:2014 is quality control during the production and certification of calibration gas mixtures. The standard requires regular checks on the purity of the reference gases, the stability of their containers, and the accuracy of the preparation methods. It also specifies the necessary information that should be provided with the certified gas mixtures, such as their composition, expiration date, and storage conditions.

Certification bodies play a crucial role in ensuring compliance with the standard. They perform audits and inspections to verify that manufacturers have implemented the necessary quality control procedures and adhere to the guidelines of BS EN ISO 6142:2014. Certification provides customers with confidence in the reliability and accuracy of the calibration gas mixtures they purchase.
