Oddy optical cable testing
The Oddy Test is an accelerated aging test that exposes silver, copper, and lead coupons to conservation materials at 60°C and approximately 100% relative humidity for 28 days (Figure 1). However, there are several limitations that exist when conducting and interpreting the Oddy. Oddy testing information, protocols, and results are provided for informational purposes only. Neither AIC nor participating institutions endorse particular methods, products, businesses, or services. Institutional protocols are not vetted or peer-reviewed and should be assessed by each individual. An Oddy Test is a procedure developed to determine the safety of materials used in contact/close proximity to delicate art objects. Oddy testing is, by its nature, subjective. A variety of manufactured materials such as foams, fabrics and adhesives are used in the conservation and display of cultural heritage objects. We have, therefore, requested Prof.
