Oddy test is an accelerated corrosion test used to evaluate the suitability of materials for use in display and storage cases in museums. The Oddy test requires three individual set-ups to study the corrosion effects of a given sample on three metals commonly involved: silver, copper, and lead. The test samples and the coupon were placed in individual air-tight, constant humidity test tubes, which were kept at 60[degree]C for 28 days. The effect of the test sample on the related metal objects was estimated by checking the corrosion of the coupon. A variant method is described here which simplifies the procedure and reduces test period by using film coupons instead of massive coupons, placing all three metal coupons into an improved test vessel, collecting digital corrosion images and analyzing them. SPME-GC/MS is simultaneously employed to identify the composition and concentration of the volatile substances emitted from the display and storage cases used in museum. The newly developed method decreased the test period to 14 days, simplified procedures, provided objective evaluation of corrosion based on digital data.
