It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ]. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.
