Acceptance inspection is an inspection carried out, upon the delivery of products of the same design and
25、of the same manufacture as those which have already passed the type inspection, to determine whether or not they satisfy the required characteristics, (5) 7.2 lows : Type Inspection The type inspection shall be performed as fol- (1) The appearance shall be visually inspected on every part of the cou
