30、he same materials, equipment, processes and procedures as will be used for regular production. The first article sample shall not be specially selected or custom made in a way that causes the product quality to be different than that expected from regular production. After inspection and provisional
31、 acceptance at source, 200 cups of the first article sample shall be inspected at the Government approved facility for all requirements of the drawings and specifications, and the remaining 5000 cups shall be used or performance of the work test. The Government reserves the right to require new init
