Scope

Main technical content: 1. Scope This standard specifies the test solutions, test equipment, methods for evaluating the corrosion performance of salt spray chambers, samples, sample placement, test conditions, test cycles, post-test sample treatment, and evaluation of test results for wheel casters. 2. Test solutions Preparation of sodium chloride solution and neutral salt spray (NSS) testing. 3. Test equipment Equipment materials, salt spray chambers, temperature control devices, spray devices, and salt mist collectors. 4. Methods for evaluating the corrosion performance of salt spray chambers Reference samples, placement of reference samples, determination of mass loss, and operational inspection of neutral salt spray devices. 5. Samples 6. Sample placement 7. Test conditions 8. Test cycles 9. Post-test sample treatment 10. Evaluation of test results Principally, compare the measured test results with those of specimens and ratings after corrosion testing on metal substrates and other inorganic coatings, and refer to Chapter 6 of GB/T 6461. In principle, the protection rating (Rp) should be no less than level 8, and the appearance rating (RA) should be no less than level 6. Samples are deemed to be qualified within the standard range, and otherwise, they are deemed unqualified.
