6.2 All forgings shall be annealed, normalized, or normal-ized and tempered, but alternatively may be liquid quenched and tempered when mutually agreed upon between the manu-facturer and the purchaser. When tempering is performed, it shall be at a subcritical temperature, but no WK73604 Revision of A668 / A668M - ASTM InternationalRationale. Class J forgings can be supplied in the normalized and tempered condition or in the normalized, quenched and tempered condition. There is no provision for testing cross sections other than Tc for class J when provided in the normalized and tempered condition as there is for all other classes of non-quenched forgings.
