Assured Testing Services has extensive experience testing various heat exchanger assemblies such as evaporators, condensers, radiators, and oil coolers.  Some of the common applicable environmental exposure tests that we conduct on heat exchangers are:

​

Corrosion Resistance:

• Salt Fog: ASTM B117, ISO 9227, etc.

• SWAAT: ASTM G85 Annex A3

• SO2 Modified Salt Spray:  ASTM G85 Annex A4

• Cyclic: Ford L467, GMW 14872, SAE J2334

• HEREL (SAE J2842)

• ASHRAE RP-1645

• OY Water Internal Corrosion

​

Pressure Testing:

Internal pressure cycling between two or more positive pressures, or one negative and one or more positive pressures; burst (failure) testing, any combination of monitored and regulated pressure and flow requirements. 

​

Thermal Cycling:

Cycling of pumped coolant between thermal endpoints, either at constant pressure or with pressure cycling.

​

We have chambers large enough to accommodate multiple full size heat exchanger units, with optional air or liquid pressurization during exposure testing.  It is also common practice to perform leak checks, leak rate determinations and failure analyses via cross sectional photomicrography upon test completion.
