Corrosion of wheelchairs is a universal issue wherein several WC parts are unable to operate after being corroded. Although ISO testing includes testing WCs in hot and cold environments, it does not test for humid conditions to simulate exposure to rainwater or waterlogged in ditches. Hence, corrosion evaluation of specific chair parts is recommended. The ISWP Corrosion Test includes testing wheelchair parts according to the ASTM B117 standard and evaluating them as per MIL-SPEC and ASTM standards. Such testing assists in evaluating the corrosion resistance of painted and coated parts.
