46、ponsibility for Inspection and TestsUnless other-wise specified in the contract or purchase order, the producer isresponsible for the performance of all inspection and testrequirements specified herein. The producer may use their ownor any other suitable facilities for the performance of theinspecti

49、 charge. If forgings are heat-treated in a continu-ous furnace, forgings charged consecutively during continuousoperation of the furnace shall be considered a furnace charge;for such forgings weighing 5 lb or less the maximum weight ofa lot shall be 2000 lb, and for heavier forgings it shall be 6000lb.6.2.2 For nonheat-treated tempers, an inspection lot shallconsist of an identifiable quantity of forgings of similar sizeand shape of the same alloy and temper subjected to inspectionat one time.7
