entary requirements specified shall be made at the place of manufacture,unless otherwi agreed upon,at the purchar’s expen.The test specified shall be witnesd by the purchar’s inspector before shipment of material,if so specified in the order.The rationale for beginning the ction numbering with S50is to eliminate the possibility of confusion with supplementary requirements existing in individual product specifications.
S50.Product Analysis(See Note S50.1)
S50.1A product analysis shall be made from each heat of ba metal and,if of welded construction,from each lot number of welding material of thefittings offered for delivery. The analysis shall conform to the requirements specified in Section8.
S51.Tension Test(See Note S50.1)
S51.1One tension test shall be made on onefitting or reprentative test piece(See Note S50.2)per lot(See Note S50.3)offittings.If thefittings are of welded construction,the tension specimen shall include the weld and shall be prepared so that the weld is at the midlength location of the specimen. However,in no ca shall the tensile properties of thefinished fitting be less than the requirements listed in the individual product specification.
N OTE S50.1—If the result of any of the tests specified in Supplementary Requirements S50,S51,or S63do not conform to requirements,retests may be made at the manufacturer’s expen on additionalfittings or reprentative test pieces of double the original number from the same heat or lot as defined in Supplementary Requirements S50,S51,or S63, each of which shall conform to the requirements specified.
N OTE S50.2—Where the test specimen for the tension or intergranular corrosion bend test cannot be taken from afitting due to size limitations, a reprentative test piece shall be obtained.The test piece shall be from the same lot it reprents and shall have approximately the same amount of working.In addition,the pieces reprentingfittings manufactured from bars,plate,or forgings shall have a cross ction equal to the greatest cross ction of thefitting,and test pieces reprentingfittings manufac-tured from pipe shall have an outside diameter and wall thickness equal to tho of thefitting.The test piece forfittings of welded construction shall be prepared to the same weld procedures and from the same heat of materials as thefittings it reprents.
N OTE S50.3—A lot shall consist of allfittings of the same type,size, and wall thickness,manufactured from one heat of material(and,if fabrication welding is performed using one lot number of electrode or one heat of weld wire),and heat treated using the same heat-treat cycle in
either a continuous or batch-tvpe furnace controlling within a range of50°F[28°C]and equipped with recording pyrometers so that complete records of heat treatment are available.
S52.Liquid Penetrant Examination
S52.1All surfaces shall be liquid penetrant examined in accordance with Test Method E165.Acceptance limits shall be specified by the purchar.Personnel performing the examina-tion shall be qualified in accordance with SNT-TC-1A-1988or later.
S53.Magnetic-Particle Examination
S53.1All accessible surfaces shall be magnetic particle examined in accordance with Guide E709.Acceptance limits shall be specified by the purchar.Personnel performing the examination shall be qualified in accordance with SNT-TC-1A-1988or later
