One of the main factors affecting the performance of cooling systems is the quality of cooling fluids. Its quality not only affects cooling efficiency but also the ability of the fluid to protect metal parts from corrosion, which can lead to malfunctions and breakdowns in the operation of equipment. To accurately assess the quality of cooling fluids, Invent Group Laboratory is implementing state-of-the-art equipment that allows tests on the corrosive activity of fluids, ensuring a high level of safety and efficiency in equipment operation.
Testing the Corrosive Activity of Cooling Fluids: ASTM D 1384 Method
The new device using the ASTM D 1384 method allows Invent Group Laboratory to test cooling fluids for corrosive activity on metallic engine components. The method is based on immersing metal samples used in engine cooling systems into a cooling fluid solution. Among them:
- copper (radiator, heat exchanger)
- brass (radiator, cylinder head)
- steel (oil cooler)
- cast iron (cylinder block)
- aluminum (cylinder block, radiator)
- solder (solder points in the radiator)
The laboratory uses specially prepared 'corrosive water', which is made by mixing distilled water with salts (sodium sulfate, sodium chloride, sodium bicarbonate). Samples of cooling fluids are mixed with 'corrosive water', creating aggressive conditions for faster results.
After holding the samples at a temperature of 88°C (close to real operating conditions of the engine cooling system) for 336 hours (2 weeks), the change in mass of the metal plates is measured, which allows assessing the impact of the fluid on the materials.
This method is a standard for testing cooling fluids in international practice and allows for comparisons of products from different brands, selecting the safest options for use.
Manufacturers use this standard to check the quality of their products. Only fluids that show low levels of corrosion can be allowed for further testing or used in engines.
Why is testing important?
Corrosion of metals in cooling systems is one of the main factors that can negatively affect engine performance. Using low-quality fluids can lead to damage to important components of the cooling system, such as radiators, heat exchangers, cylinder heads, cylinder blocks, and other parts. This, in turn, can cause serious engine malfunctions that require expensive repairs or part replacements.
Using the ASTM D 1384 test, Invent Group Laboratory can assess whether the cooling fluid has an aggressive effect on the components of the cooling system and identify products that may be hazardous to equipment. This allows for making the right choice and ensuring reliable operation of the equipment.
