Ko ngā uara kei waho i ēnei awhe he tohu pea nō ngā take kounga.
Etirena Karikora Ka taea hoki te tautuhi i ngā māka mā te waikawa (ka tatauhia hei waikawa acetic), e whakaata ana i ngā poke waikawa:
Teitei o te Kounga: ≤ 0.001%
Ethylene Glycol Tau Waenga: 0.001%–0.003%
Ethylene Glycol Papa Iti: > 0.003% (tērā pea ka pā kino ki ngā tukanga o muri mai)
Mai i te tirohanga o te whānuitanga whakatō (i te 0°C, 101.3 kPa):
Te Tohu Tino Pai o te Ethylene Glycol: 196–199°C
Tau Tuatahi: 195–200°C
Tohu Paetae Ethylene Glycol: 194–201°C
Ko te whaiti o te awhe whakarewa e tohu ana i te parakore teitei ake.
