1.2 In case of conflict in requirements, the requirements of the individual product specifications shall prevail over those of this specification. 1.3 The purchaser may specify additional requirements (see ) that do not negate any of the provisions of either this specification or of the individual product specifications. The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order. 1.4 If, by agreement, forgings are to be supplied in a partially completed condition, that is, all of the provisions of the product specification have not been filled, then the material marking (see Section ) and certification (see Section ) shall reflect the extent to which the product specification requirements have been met. |
