GB/T 26491-2011 "5XXX series aluminum alloy intergranular corrosion test method mass loss method" stipulates the test method for the determination of intergranular corrosion of 5XXX series aluminum alloys by mass loss method. The standard covers the test principle, sample preparation, test solution, operation steps and result calculation. By measuring the mass change of the sample before and after corrosion, the degree of intergranular corrosion of 5XXX series aluminum alloys is quantitatively evaluated, which provides a scientific and standardized detection method for accurately judging the corrosion resistance performance of this series aluminum alloy and ensuring the mass of the product.
