Any selected type of rigid metal container with machine seamed or reusable gasketed closure may be used if the container provides a WVTR not exceeding 0.075 grams per 100 square inches per 24 hours, when tested in accordance with ASTM-D1008 unless a specific type of container and closure is specified in the contract or purchase order. When specified in the contract or purchase order or when dictated by the requirements of the item, the metal container may be vacuum sealed.'
