4、obium alloy.1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI unitsare to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system mustbe used independently of the oth

5、er. SI values cannot be mixed with inch-pound values.1.3 The following precautionary caveat pertains only to the test method portions of this specification. This standard does notpurport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of t
