A well established means of refining estimates of levels of loss is to consider the temperature of the clamp, or at least the temperature of the environment in which the clamp stands. The role of temperature as a proximate cause of loss is well documented in the literature, and dates back at least to the late 1940s, when a number of trials on large scale commercial factory storage in the US were being conducted (see for example Gaddie and Tolman, 1952). Subsequent laboratory and field trials have repeatedly verified these results, adding nuance to the point where the relationship is satisfactorily understood both in terms of mechanisms and the correlation, covariates and limits in the relationship.1
