Scope
GB/T 43356-2023 is the English-translated version of 钢筋腐蚀盐溶液周期浸润试验方法.
GB/T 43356-2023 is the Chinese national test method for judging how well steel bars resist corrosion in a chloride salt solution environment under alternate immersion.
Clause 1 covers the test equipment, the test solutions, the test conditions, the specimens, the test time, the test steps, the evaluation of results and the test report, and clause 4 states that a cycle immersion corrosion testing machine is used, other equipment meeting the test conditions of the document being allowed.
Clause 1 states that it applies to the evaluation of the corrosion resistance of steel bars, and that the corrosion performance of welded steel bar connections may be evaluated with reference to it.
It quotes GB/T 1266 for sodium chloride reagent and GB/T 16545-2015 for removing corrosion products. Issued on 27 November 2023, it has applied since 1 June 2024.
