This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
This specification adopts the requirements of ISO 6848:2004 and incorporates the provisions of earlier versions of AWS A5.12, allowing for classifications under both specifications.
