    WK26242

    1. Scope

    This test method covers determination of the compatibility of commercial engine coolant concentrates and residual fuses flux in CAB brazed aluminum heat exchangers. This test method focuses on the stability of specific chemical species formed in the engine coolant. The test method is of limited use for ranking chemical compatibility problems in coolant additive packages. It is capable of indicating the possibility that precipitation in CAB-brazed aluminum heat exchangers that contain fused flux may occur.

    Recent experiences and presentations in the industry have suggested that this situation is significant and that avoiding incompatibility of coolants in CAB brazed aluminum heat exchangers may have very great value.
