When required (ee 3.7.2), each piece of each lot hall be inpected Sampling for duplex tructure examination. A ample for duplex tructure examination hall be taken from a lice at leat 3 / 8 inch thick from one end of a bar, rod or forging repreenting each heat treat lot Examination method Straightne of rod. In determining traightne in the tandard 42 inch ditance between upport or in determining traightne when upported at the end, the rod hall be placed on a preciion table equipped with ballbearing roller and a micrometer or dial indicator. The rod hall then be rotated lowly againt the indicator, and the deviation from traightne in any portion of the rod between the upport hall not exceed the permiible variation pecified in table X and XI. The deviation from traightne (throw in one revolution) i defined a the difference between the maximum and minimum reading of the dial indicator in one complete revolution of the rod. Straightne in term of depth of chord hall be determined with a traightedge, the length of which i not le than that of the piece being meaured Straightne of bar, heet, and trip. Straightne in term of depth of chord hall be determined with a traightedge and hall not exceed the permiible variation in and Viual and dimenional acceptance criteria. Each ample taken in accordance with hall be ubjected to urface inpection for workmanhip and dimenion. Any ample lot unit containing one or more viual or dimenional defect hall be rejected Inpection of hot finihed material. Rod or bar urface hall be examined to locate imperfection of maximum everity. Thee imperfection hall be explored by grinding, filing, or otherwie reducing the cro-ection 25

26 dimenion at the ite of the imperfection. Sufficient material hall be removed to reach the bottom of the imperfection. The cro-ection dimenion i meaured at thi point. If the depth of the imperfection doe not exceed the machining allowance in table XXIII for the applicable ize and form, the product will be acceptable. 4.3 Tet procedure Chemical analyi. The ample elected in accordance with hall be analyzed by the wet chemical or pectrochemical method to determine conformance with table I. In cae of diagreement, the chemical compoition hall be determined in accordance with ASTM E Mechanical tet Aged material. Mechanical tet required for material hipped in the aged condition hall be done on a ample taken from the material after the final heat treatment. Mechanical tet ued to demontrate the capability of a lot to meet the mechanical tet requirement (ee ) may not be ued certify a lot of material hipped in the aged condition Unaged material. When mechanical tet are required for material ordered in the unaged condition to demontrate the capability of the lot to meet the mechanical teting requirement (ee 6.2), the tet pecimen, taken from each lot per , , and , hall be obtained from the material a it i to be to be hipped or from a forged tet coupon, when applicable and heat treted a pecified (ee 6.2). When no heat treatment i pecified, the pecimen hall be annealed, if the material to be hipped ha not been annealed, and aged in accordance with Mechanical tet on a lot from the ame heat that ha previouly been teted in the ame condition (ee 1.2.1), heat treated a pecified above, and found to meet the requirement of thi pecification may be ued to demontate the capability of the lot of unaged material to meet the mechanical tet requirement Heat treatment of unaged mechanical tet pecimen. Unle otherwie pecified (ee 6.2), age hardening of the tet pecimen in hall be performed by heating to F, holding at temperature for 8 to 16 hour depending on hardne of material and deired hardne after aging, furnace cooling to an aim temperature of 900 F then air cooling to room temperature Bar, rod, rectangle, and forged part. All bar, rod, rectangle, and forged part hall be teted full-ize when practicable. When a machined pecimen become neceary, enough metal may be removed from the gauge ection to meet the limitation of the teting machine or the pecimen may be machined to the form and dimenion of the larget tandard round pecimen in ASTM E 8 obtainable from the product being teted. When the product being teted i of uch ize that an ASTM E 8 round pecimen le than inch diameter i needed, minimum elongation requirement of table III hall not apply Axi of the tet pecimen. For bar, rod, rectangle, and forged part up to and including 1½ inche in diameter or thickne, the axi of the tet pecimen hall coincide with the central axi of the piece; over 1½ inche, the axi hall be located midway between the center and urface of the piece. 26

The axi of tenion tet pecimen for bar, rod, rectangle, and forged part hall be parallel to the direction of rolling, drawing, or flow of metal Tenion tet pecimen of plate, heet, and trip. Tenion tet pecimen for plate, heet, and trip under inch thick hall be machined to the form and dimenion of a tandard 2 inch gauge length flat in conformance to ASTM E 8. Tenion tet pecimen for plate inch and over in thickne hall be machined to the form and dimenion of the larget obtainable tandard round in conformance to ASTM E Direction of tenile tet pecimen. Tenile pecimen from plate, heet, and trip hall be taken tranvere to the direction of rolling when width will permit Bend tet pecimen of heet and trip. Bend tet taken from heet and trip hall be full thickne longitudinal pecimen teted in conformance with ASTM E 290. The radiu of the pin or mandrel and the angle of bend hall be a pecified in table VI Tenion tet pecimen of wire. Tenion tet pecimen hall be of the full cro-ection of the wire and not le than 15 inche in length. Specimen hall be free from harp bend or kink.
