View License Agreement The fact that a change takes place in metals under exposure conditions is not in itself usually serious; in almost all uses to which metal is put allowances are made for some change. It is rather the rate of change that is significant. Furthermore the tolerated rate of change varies with the application. The conception of an upper limit of usefulness of metals is, therefore, in a sense arbitrary. The expression of such limits should not lead to misinterpretation once it is recognized that these are not absolute. | ||
