This Standard provides practical procedures for use in the field, to evaluate the surface profile of a prepared metal substrate to which a protective coating is to be applied. This Method is applicable to surfaces that have been prepared by abrasive blast cleaning in accordance with AS 1627.4.

This Standard provides practical procedures for use in the field, to evaluate the surface profile of a prepared metal substrate to which a protective coating is to be applied.This Method is applicable to surfaces that have been prepared by abrasive blast cleaning in accordance with AS 1627.4.Four methods are described for assessing surface profile.NOTES: 1 Results obtained using different methods are not necessarily comparable.2 Surface profile does not play any part in surface cleanliness.
