EN 589 6.3 Anex A Odour Test Instrument for Liquefied Petroleum Gas (LPG)

The odour of commercial liquefied petroleum gas (LPG) is usually caused by unsaturated hydrocarbons, sulfur-containing compounds, or added odorants. This instrument describes a method for evaluating the odor of commercial LPG.

Test method:A liquefied gas sample that has been completely vaporized is diluted with purified air to achieve a concentration of the target gas in the mixture that is 20% of its lower explosive limit. At least three operators should be involved to assess the odor of the mixed gas.
Note: The lower explosive limit of the gas in air is a volume fraction of 1.9% for butane and 2.4% for propane.
