This guide describes the use of reference photographs depicting the appearance of unpainted, painted, rusteed, and welded hot-rolled carbon steel prior to and after power- and hand-tool cleaning.
Each color photograph provides one possible illustration of the minimum acceptable level of cleanliness.
The photographs are intended to be used to supplement the written SSPC power- and hand-tool surface preparation standards.
This guide is in three languages: English, Spanish, and Portuguese.
This guide describes the use of reference photographs depicting the appearance of unpainted rusted carbon steel and painted carbon steel, with or without rust, prior to and after cleaining by waterjetting.
This guide, which consists of actual-size color photographs, can be used to clarifty the acceptable level of flash rusting allowed prior to the application of protective coatings.
SSPC-SP 13/NACE No. 6, “Surface Preparation of Concrete” has just been revised and given a major face lift. It is quite different than the previous 2003 version with more content. It became evident during the revision of the standard that there was wide and intense interest and so this presentation is meant as an introduction to the new standard highlighting the revisions.
This standard, SSPC-SP 10 (WAB)/NACE WAB-2, defines the "Near-White Metal" level of surface cleanliness for wet abrasive methods. Other levels in overview below.
HISTORICAL DOCUMENT. Requirements for "Near-White Metal" - one of five levels of cleanliness of steel surfaces achieved by blast cleaning with the use of abrasives. (White Metal, Near-White Metal, Commercial, Industrial, Brush Off)
This AMPP standard covers the preparation of concrete surfaces before the application of protective coating or lining systems. This standard should be used by specifiers, applicators, inspectors, and others who are responsible for defining a standard degree of cleanliness, strength, profile, and dryness of prepared concrete surfaces.
Requirements for "Industrial" - one of five levels of cleanliness of steel surfaces achieved by blast cleaning with the use of abrasives. (White Metal, Near-White Metal, Commercial, Industrial, Brush Off)
HISTORICAL DOCUMENT. This standard covers surface preparation of coated or uncoated metal surfaces other than carbon steel prior to the application of a protective coating system. Surface preparation using this standard is used to uniformly roughen and clean the bare substrate and to roughen the surface of intact coatings on these metals prior to coating application. Substrates that may be prepared by this method include, but are not limited to, galvanized surfaces, stainless steel, copper, aluminum, and brass. For the purpose of this standard, the zinc metal layer of hot-dip galvanized steel is considered to be the substrate, rather than the underlying steel. This standard is not to be used for cleaning coated or uncoated carbon steel substrates.
Hand tool cleaning is a method of removing loosely adherent foreign matter from steel substrates using hand-held tools without supplemental power.
Power tool cleaning is a method of preparing steel surfaces by the use of power-assisted hand tools. It does not include the use of laser and heat-induction technologies.
