Antifreeze Analysis
Glycol Based Engine Coolant (Antifreeze) Analysis Used in Automobiles and Light Commercial VehiclesWe analyze ethylene glycol or propylene glycol-based engine coolants used in automobiles or other light-duty cooling systems according to ASTM D 3306 standard. Antifreezes function effectively to protect against freezing, boiling, and corrosion when used in water at a concentration of 40 to 70% by volume, or when pre-diluted glycol-based engine coolants (minimum 50% by volume) are used without further dilution.
Coolants are classified as follows;
- Type I Ethylene glycol based concentrate
- Type II Propylene glycol based concentrate
- Type III Ethylene glycol pre-dilution (50% by volume)
- Type IV Propylene glycol pre-dilution (50% by volume)
