Temper7.1 Drawn Tempers, HThe tempers of drawn tube shall bedesignated as light-drawn (H55), drawn (H58), and hard-drawn(H80) (see Table 2).
18、Light-drawn (bending) temper is used onlywhen a tube of some stiffness but yet capable of being bent isneeded. Drawn temper is for general purposes and is mostcommonly used where there is no specific requirement for highstrength on the one hand or for bending qualities on the other.Hard-drawn temper
19、 is used only where there is need for a tubeas strong as is commercially feasible for the sizes indicated.For any combination of diameter and wall thickness notcovered under hard-drawn temper, the values given for drawntemper shall be used. Rectangular including square tubes shallnormally be supplie
20、d only in drawn (general-purpose) temper.When there is a need for light-drawn or hard-drawn tempersthese are to be supplied as agreed upon between the manufac-turer and the purchaser.7.2 Annealed Tempers, OThe tempers of annealed tubeshall be designated as light anneal (O50) and soft anneal (O60)(Ta
21、ble 3).NOTE 2Tube of Copper Alloy UNS No. C23000, when specified tomeet the requirements of the ASME Boiler and Pressure Vessel Code, shallhave in the annealed condition a minimum tensile strength of 40 ksi anda minimum yield strength of 12 ksi at 0.5 % extension under load, inwhich case the provisi
22、ons for grain size and Rockwell hardness in 8.2 donot apply.8. Mechanical Properties8.1 Drawn TemperTube shall conform to the mechanicalproperties prescribed in Table 2. Tension tests are required fortubes with a wall thickness under 0.020 in. and for round tubeshaving an inside diameter under516 in
23、. and for rectangularincluding square tubes having a major distance between insideparallel surfaces under316 in. The tension test for other sizes oftubes need not be made except when indicated by the purchaserat the time of placing the order. A convenient method ofindicating that the tension test is
24、 required is to specify that“Test procedure T is required” (see 4.1.3). When agreementon the Rockwell hardness tests cannot be reached, the tensilestrength requirements of Table 2 shall be the basis for accep-tance or rejection.8.2 Annealed TemperTube shall conform to the grain sizeand Rockwell hard

Nondestructive Testing11.1 Unless nondestructive testing has been waived, tubesshall be subjected to a nondestructive test.
34、The manufacturershall select the nondestructive test that is most suitable for thetube size and the application.11.1.1 Eddy-current testing is the standard nondestructivetest, and all tubes of appropriate size shall be eddy-currenttested in accordance with 11.2.11.1.2 Tubes that are not of a size su

Testingshall follow the procedure of Pra
36、ctice E 243, except thedetermination of “end effect” is not required. Tubes shall bepassed through an eddy-current test unit adjusted to provideinformation on the suitability of the tube for the intendedapplication.11.2.1 Notch-depth standards rounded to the nearest 0.001in. shall be 22 % of the nom
