Taking samples of liquefied hydrocarbon gases (LPG, propane, butane, propane-butane) according to the current standard PN-EN ISO 4257 and ZN/MG/CN-18:2007
One of the basic activities involved in assessing the properties of hydrocarbon gases (LPG, propane, butane, propane-butane) is proper (compliant with the requirements) sampling for testing by a professional laboratory.

Carrying out quality tests on samples of liquefied hydrocarbon gases based on standardised methods in the field:
◦ content of C1-C5 hydrocarbons (gas chromatographic method) according to PN-EN 27941;
◦ dien content (gas chromatographic method) according to PN-EN 27941;
◦ total sulphur content (ultraviolet fluorescence method) according to ASTM D 6667;
◦ motor octane number (from calculation) according to PN-EN 589;
◦ vapour pressure at temperatures (-10), (-5), 0, 10, 20, 37.8, 40, 50, 70 °C (from calculation) according to PN-EN ISO 8973 and PN-EN 589;
◦ temperature at which the relative vapour pressure is at least 150 kPa (from calculation) in accordance with PN-EN ISO 8973 and PN-EN 589;
◦ corrosive action on copper (visual method) acc. to PN-EN ISO 6251;
◦ presence of hydrogen sulphide (visual method) acc. to PN-EN ISO 8819
◦ presence of water (visual method) acc. to PN-EN 15469, PN-C-96008;
◦ odour test (organoleptic method) according to PN-EN 589;
◦ density at 15°C (from calculation) according to PN-EN ISO 8973;
◦ calorific value (from calculation) according to PN-C-96008;
◦ absolute vapour pressure at temperatures (-15), 40, 70°C (from calculation) according to PN-C-96008;
◦ density at 15.6°C (from calculation) according to PN-C-96008;
◦ mineral oil content (by weight) according to PN-C-96008;
◦ determination of dissolved residues (gas chromatographic method) according to PN-EN 15470;
◦ issue of documentation with test results.
