Rationale: Add this statement for two reasons: 1) no clear definition for peak load occurs within this test method and 2) due to the current variety of material in the marketplace, it would be better that the individual product specifications determine the value necessary to determine ultimate elongation properly Rationale: Add a set percentage, or set overall value, and See the product specification for the value of the set percentage or set overall value. due to the current variety of material in the marketplace, it would be better that the individual product specifications determine the best values to use to determine ultimate elongation for comparing products that meet that product specification. Add the last sentence for two reasons: 1) no clear definition for peak load occurs within the test method and 2) this term should be defined to prevent confusion with peak load since both terms are used within the test method, but are not interchangeable in their use.
