Natural gas. Upstream area. Determination of composition by Laser Raman spectroscopyWhat is ISO 23978 about? ISO 23978 describes a laser Raman spectroscopy method for the quantitative determination of the chemical composition of natural gas in the upstream areas. Gas laser Raman spectrometry is a simpler and more direct analysis method than gas chromatography. Gas laser Raman spectrometry enables rapid and simultaneous analysis of multiple gas species because each type of gas molecule emits unique light frequencies shifted from the

that have strain to fracture less than or equal to 5% and show linear elastic behavior to fracture

and the form that they take

This document provides several examples of varying complexity which illustrate the use and intent of the performance assessment methodology set out in ISO 24510

BS EN 49-1 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment to wood

test results obtained according to the previous methodology still maintain their validity
