EN ISO 6143:2017 is a technical standard that provides guidelines and requirements for gas analysis in industrial and laboratory environments. It specifies the methods and procedures to be followed for accurate measurement of various gases, including their concentrations, purity levels, and impurities. This article aims to provide an in-depth of EN ISO 6143:2017 and its significance in ensuring reliable gas analysis results.
Scope of EN ISO 6143:2017
The scope of EN ISO 6143:2017 covers gas analysis methods for both online and offline measurements. It encompasses a wide range of gases, such as oxygen, nitrogen, carbon dioxide, methane, and other hydrocarbons. The standard applies to various industries, including chemical, petrochemical, pharmaceutical, environmental, and food production, where accurate gas analysis is crucial for quality control, safety compliance, and process optimization.
Key Requirements and Procedures
EN ISO 6143:2017 outlines specific requirements and procedures to ensure the accuracy and reliability of gas analysis results. Some key provisions include:
Sampling Techniques: The standard describes appropriate sampling techniques to obtain gas samples representative of the analyzed medium. It includes considerations for sample collection, transport, and preservation to minimize contamination or alteration of the gases being measured.
Calibration and Verification: EN ISO 6143:2017 emphasizes the importance of calibration and regular verification of gas analyzers. It provides detailed instructions on how to calibrate instruments using traceable reference standards and how to verify their performance at defined intervals.
Measurement Uncertainty: The standard requires the estimation of measurement uncertainty associated with gas analysis. It provides guidance on factors influencing uncertainty, such as sampling, equipment performance, and environmental conditions. The quantification of uncertainty helps in assessing the reliability and comparability of gas analysis results.
Benefits and Importance
Adherence to EN ISO 6143:2017 brings several benefits to both industries and laboratories conducting gas analysis:
Accuracy and Reliability: Following the standard's guidelines ensures accurate and reliable gas analysis results, enabling informed decision-making and preventing potential risks associated with incorrect readings.
Inter-laboratory Comparability: EN ISO 6143:2017 ensures that gas analysis results obtained from different laboratories are comparable. This facilitates data exchange, collaboration, and harmonization of practices among various stakeholders.
Quality Assurance: Compliance with the standard enhances quality assurance programs by setting consistent criteria for gas analysis. It helps organizations demonstrate their commitment to quality control, customer satisfaction, and regulatory compliance.
