| Term (EN) | gum |
| Definition (EN) | polymeric or oxygen-containing component of
gasolines or middle distillates that is soluble in the
product under normal storage and handling
conditions, but is deposited on evaporation.
NOTE 1 Specified evaporation procedures may modify
the structure of these compounds, or form new
compounds from hydrocarbons existing in the product
under test.
NOTE 2 Since many of the reactions leading to gum
formation are oxidation-type, the use of additives to slow
or prevent the onset of oxidation is common. |

| Term (BS) | smola |
| Definition (BS) | polimerska ili oksigenska komponenta benzina ili
srednjih destilata koja je topiva u proizvodu pod
normalnim uvjetima skladištenja i rukovanja, ali se
kod isparavanja taloži
NAPOMENA 1 Specifični postupci isparavanja mogu
modificirati strukturu tih spojeva, ili mogu formirati nove
spojeve od karbonhidrogena koji postoje u proizvodu
koji se ispituje.
NAPOMENA 2 Pošto su mnoge reakcije, koje dovode
do stvaranja smole, oksidacijskog tipa, uobičajena je
upotreba aditiva za usporavanje ili sprječavanje početka
oksidacije. |
