Number of Tests and Retests10.1 In the case of sheet or strip supplied in coil form, two or more tension tests (one from each end of each coil), and one ormore hardness
22、tests shall be made on specimens taken from each end of the coil. When material is supplied in flatsheet, flat strip,or plate, one tension and one or more hardness tests shall be made on each 100 or less sheets, strips, or plates of the same lot. Whenspecified, one corrosion test shall be conducted
23、for each lot.10.2 If any specimens selected to represent any lot fail to meet any of the test requirements, the material represented by suchspecimens may be retested. If there is valid reason to believe the result is not representative, the material may be re-reannealedand retested.11. Specimen Prep

Sheets of any one item of a specified thicknessand size in any finish may be overweight to the following extent:(1)
31、 An 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
32、.(3) 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.
