Is difluoromethane a liquefied hydrocarbon?

Difluoromethane, explosion limit 14%-31%, according to petrochemical regulations. Is difluoromethane a liquefied hydrocarbon?
This question should not be asked like this. It is a hydrocarbon itself and can be liquefied. It cannot be called liquefied hydrocarbons under normal pressure. It can only be called liquefied hydrocarbons after it is liquefied under certain conditions.
First of all, hydrocarbons are hydrocarbons. If it contains fluorine, it is not a hydrocarbon, and it is obviously not a liquefied hydrocarbon. Secondly, there are clear term definitions in the petrochemical regulations gb50160.
Personally think: R32 is not that flammable at room temperature. This is different from hydrocarbon liquids. It cannot be classified as liquefied hydrocarbons.
