ASTM E202 Test Method for Analysis of Ethylene Glycols and Propylene Glycols
To measure certain chemical and physical properties of ethylene glycols and propylene glycols ASTM E202 is used and it can be used to determine compliance with specifications in which limits are established for these properties.
Scope:
The ASTM E202 test methods cover the chemical and physical analysis of the commonly available grades of ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, and dipropylene glycol.
| Test | Section |
| Purity of Reagents | 4 |
| Specific Gravity | 6-8 |
| Distillation Range | 9-11 |
| Acidity | 12-14 |
| Water | 15-17 |
| Iron | 18-20 |
| Colour | 21-23 |
| Gas Chromatographic Analysis | 26-26 |
Result:
Water Content in Ethylene Glycols and Propylene Glycols is determined by Coulometric Karl Fischer Titration
Conclusion:
To measure certain chemical and physical properties of ethylene glycols and propylene glycols ASTM E202 is used and it can be used to determine compliance with specifications in which limits are established for these properties.
