16、ormed in accordance withSpecification B 906, except as specified herein:9.1.1 PlateA lot of plate for testing and inspection pur-poses shall consist of the products resulting from the rolling ofone heat of material in the same condition and specifiedthickness, solution annealed by the same practice,
17、 but in nocase more than 25 000 lb (11 340 kg).9.1.2 Sheet and StripA lot of sheet or strip for testing andinspection purposes shall consist of material from one heat inthe same form (sheet or strip), condition, finish, and specifiedthickness, solution-annealed by the same practice but in nocase mor
18、e than 25 000 lb (11 340 kg).9.2 Sampling for Mechanical Tests:9.2.1 When samples are to be taken after delivery, thepurchaser of material ordered to cut lengths may request on thepurchase order additional material of adequate size to providesample coupons for inspection purposes.10. Number of Tests
19、 and Retests10.1 In the case of sheet or strip supplied in coil form, twoor more tension tests (one from each end of each coil), and oneor more hardness tests shall be made on specimens taken fromeach end of the coil. When material is supplied in flatsheet, flatstrip, or plate, one tension and one o
20、r more hardness tests shallbe made on each 100 or less sheets, strips, or plates of the samelot. When specified, one corrosion test shall be conducted foreach lot.10.2 If any specimens selected to represent any lot fail tomeet any of the test requirements, the material represented bysuch specimens m
21、ay be retested. If there is valid reason tobelieve the result is not representative, the material may bere-reannealed and retested.11. Specimen Preparation11.1 Tension test specimens from material under12 in. (12.7mm) in thickness shall be of the full thickness of the materialand machined to the for

Sheets of any one item of a specified thicknessand size in any finish may be overweight to the following extent:(1) An item of five sheets or less, or an item estimated to weigh 200 lb (90.7 kg) or less, may actu
27、ally weigh as much as 10 % over thetheoretical weight.(2) An item of more than five sheets and estimated to weigh more than 200 lb (90.7 kg) may actually weigh as much as 712 % over thetheoretical weight.(3) The underweight variations for sheets are limited by the under thickness tolerances shown in
28、 Table 3 of Specification B 906.For determining theoretical weight, the factor 42 lb/ft2in. (0.0008 kg/cm2mm) thickness may be used.B 709 04 (2009)2dimensions shown for the plate-type specimen in Test MethodsE 8/E 8M.
