For the purposes of this standard, a shutdown includes the actual downtime period and the contiguous periods required to shut down and start up the equipment.

For the purposes of this standard, the term austenitic materials includes austenitic stainless steels and other austenitic alloys.

For the purposes of this standard, the term other austenitic alloys refers to those alloys of nickel, iron, and chromium that may be susceptible to PTA SCC.
