1.1''This practice covers definitions and procedures for measuring flatness characteristics of uncoated steel sheet and nonmetallic and metallic-coated steel sheet. The methods described are designed and intended to be used in mill situations and environments.

1.2''The sheet shall conform to all the requirements of the appropriate specifications as follows: Specifications A568/A568M or A924/A924M.
