摘　　要：简要介绍了NB/SH/T0521-2010发动机冷却液标准,概述了发动机冷却液使用性能的评定方法,重点探讨了乙二醇型和丙二醇型冷却液腐蚀与泡沬测定中试验溶液的差异,产生差异的原因是乙二醇和丙二醇对冷却液的冰点影响规律不同,以实例介绍了配制试验溶液的详细方法。The NB/SH/T0521 standard specification is briefly introduced, the test methods used to assess the performance of engine coolants is summarized, the difference of test solution used to evaluate the anti - corrosive properties and the anti - foaming characteristics of coolants between ethylene glycol base engine coolants and propylene glycol base engine coolants is emphasized, the reason caused the difference is that the influence of ethylene glycol and propylene glycol on the freezing point of coolants is different, the method of how to confect the test solution in particular is introduced with examples.
