or both， that provide explanatory material. Such notes and
footnotes， excluding those in tables and figures， do not contain
any mandatory requirements.

nished without heat treatment or with stress relieving only， the
additional requirements， including additional testing require-
ments and the reporting of additional test results， of A 6/A 6M
