BiH standard BAS EN ISO 6974-3:2024, Natural gas - Determination of composition and associated uncertainty by gas chromatography - Part 3: Precision and bias

The third edition of BAS EN ISO 6974-3:2024 was prepared in a bilingual version, in Bosnian and English.

The text of this international standard was prepared by the Technical Committee ISO/TC 193, Natural gas, in cooperation with the Technical Committee CEN/TC 238, Test gases, test pressures, appliances categories and gas appliance types, whose secretariat is held by AFNOR.

This standard describes the precision that can be expected from the gas chromatographic method that is set up in accordance with ISO 6974-1. The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in ISO 6974-1 is applied in one or more competent laboratories. This document also gives guidance on the assessment of bias.

BAS EN ISO 6974-3:2024 was prepared by the Technical Committee of the Institute for Standardization of Bosnia and Herzegovina, BAS/TC 31, Gas and gas engineering.
