Abstract
The clamps of the present invention are initially placed apart with a specific separation to properly hold the garments in the constant rate of expansion (CRE) machine. The test method preferably uses panties that have been prepared according to specific test criteria and the CRE machine pre-programmed with specific parameters including the preload and the initial rate of extension. Before testing commences, the midpoint of an individual panty is placed at the center of the clamps. After a pre-determined resistance is sensed by the CRE machine, the rate of extension and the load instantly increase to test the panty's percent of elongation and modulus. This method is repeated for several styles and sizes of panties to obtain accurate, consistent elongation and modulus measurements for each style and size. These measurements thus categorize all of the measured styles and sizes into a standardized panty support classification system.
