Natural gas — Correlation between odorant concentration in air and odour intensity

This document describes how to establish the correlation between odorant concentration in air and odour intensity, usually presented in the form of odour intensity curves, following the odour intensity scale presented in Clause 5. This document does not fix a required level of odour intensity in the natural gas: this prescription is specified by local/national regulation.
