| Definition (EN) | mass per unit volume
NOTE 1 For a fire effluent (4.105) the typical units are grams per cubic metre (g⋅m-3).
NOTE 2 For a toxic gas (4.336), concentration is usually expressed as a volume fraction (4.351) at T =298 K and P =1 atm, with typical units of microlitres per litre (μL/L), which is equivalent to cm3/m3or 10-6.
NOTE 3 The concentration of a gas at a temperature, T, and a pressure, P can be calculated from its volume fraction (assuming ideal gas behaviour) by multiplying the volume fraction by the density of the gas at that temperature and pressure. |

NAPOMENA 1 Za produkte požara (4.105) tipične jedinice su grami po metru kubnom (g⋅m-3).
NAPOMENA 2 Za toksični gas (4.336) koncentracija se obično izražava kao zapreminski udio (4.351) na T =298 K i P =1 atm, s tipičnim jedinicama mikrolitar po litru (μL/L), što je ekvivalentno cm3/m3 ili 10-6.
NAPOMENA 3 Koncentracija gasa na temperaturi, T, i pritisku, P, može biti izračunata iz zapreminskog udjela (pretpostavljajući idealno ponašanje gasa) množenjem zapreminskog udjela s gustinom gasa na toj temperaturi i pritisku. |
