3.   DEFINITIONS

3.1   High Strength Steel. For the purpose of this standard, high strength steel is defined  as  steel  heat  treated  to  1240  mega-pascals  (MPa)  (126  kilogram  -  force  per millimeter square {Kgf/mm2} 180,000 pound - force per square inch {PSI}) and above.

4. GENERAL REQUIREMENTS
