Suðumarksmæling/frostmarksmæling ... felst í mælingu á hækkun suðumarks (suðumarksmæling) eða lækkun frostmarks (frostmarksmæling) leysis þegar fjölliðu er bætt út í hann.
- [en] Ebullioscopy/Cryoscopy ... involves measurement of boiling point elevation (ebullioscopy) or freezing point depression (cryoscopy) of a solvent, when the polymer is added.

- [en] Note: As the method relies on the fact that the effect of the dissolved solute on the freezing point of the solvent is dependent on the molecular weight of the solute, by dissolving a known quantity of it in a solvent and recording the amount by which the freezing point of the solvent drops the molecular weight of a solute can be determined (IATE)
Not to be confused with cryometry which is the measurement of extremely low temperatures, by means of a cryometer (IATE)
This kind of measurement is called cryoscopy (Greek cryo = cold, scopos = observe "observe the cold") and relies on exact measurement of the freezing point. (Wikipedia) - Orðflokkur
