Reference conditions DIN 1343
pressure: 1,01325 bar, air humidity: 0%, temperature: 0°C.
Did you know, that under defined conditions (DIN 1343: pressure = 1.01325 bars, air humidity = 0%, temperature = 0°C and ISO 2533: pressure = 1.01325 bars, air humidity = 0%, temperature = 15°C.) a standard cubic metre of gas has an actual volume of 1m³? However, the volume changes if the conditions differ.
