ASTM B551/B551M-07
Standard Specification for Zirconium and Zirconium Alloy Strip, Sheet, and Plate
1.1 This specification covers five grades of zirconium strip, sheet, and plate.
1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
