Number of Tests and Retests10.1 In the case of sheet or strip supplied in coil form, twoor more tension tests
21、 (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 or more hardness tests shallbe made on each 100 or less sheets, strips, or plates of the samelo
22、t. 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 may be retested. If there is valid reason tobelieve the result is not representative, the mater
23、ial may bere-reannealed and retested.11. Specimen Preparation11.1 Tension test specimens from material under12 in.

Sheets of any one item of a specified thicknessand size in any finish may be overweight to the following extent:(1) An
30、item of five sheets or less, or an item estimated to weigh 200 lb (90.7 kg) or less, may actually 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)
31、 The underweight variations for sheets are limited by the under thickness tolerances shown in Table 3 of Specification B906.For determining theoretical weight, the factor 42 lb/ft2in. (0.0008 kg/cm2mm) thickness may be used.B709 173TABLE 5 Thickness ToleranceA,B,Cfor Cold-Rolled Strip for the Thickn
