摘要

In my previous column, I discussed the need for standardization of test methods and the progress that has been made in recent years (see "Learn More," p. 11). However, we know from that column, and many preceding it, that when we attempt to determine material properties, there is often more than one "standardized" test method available for measuring a specific property. In some cases there are many. The questions then arise: Are these various test methods comparable? Do they produce statistically equivalent experimental results? Any attempt to answer these questions is complicated by the fact that the test methods in question could spring from many sources: company standards, government standards from around the world, consortia standards, national standards written for various nations by their own groups of technical experts, and formal standards written collectively by individuals and groups representing many nations. An investigation could, therefore, be international in scope.
