Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease,[1]tin blight, tin plague,[2] or tin leprosy.[3] It is an autocatalytic process, accelerating once it begins. It was first documented in the scientific literature in 1851, having been observed in the pipes of pipe organs in medieval churches that had experienced cool climates.[4]
With the adoption of the Restriction of Hazardous Substances Directive (RoHS) regulations in Europe, and similar regulations elsewhere, traditional lead/tin solderalloys in electronic devices have been replaced by nearly pure tin, introducing tin pest and related problems such as tin whiskers.[5][6]
