JC/T 2138-2012 "Test method for acid and alkali corrosion performance of fine ceramics" standard specifies the determination method of corrosion performance of fine ceramics in acid and alkali solution. This standard covers test terms, definitions, required instrumentation and equipment, selection of corrosion solution, sample prepative and test steps. It is suitable for evaluating the Stability and durability of fine ceramics in chemical environment, involving the use of sulfuric acid, sodiumhydrate and other solutions. The test method includes the determination of solution concentration, the soaking time of the sample and subsequent performance evaluation. This standard is applicable to the testing of bulk fine ceramics and can also provide a reference for the evaluation of chemical corrosion resistance of Miscellaneous inorganic Non-metallic materials.
