SSPC-SP10 /NACE 2 - Near-White Blast Cleaning: A Near White Blast Cleaned surface, when viewed without
<br />magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust, paint, oxides, corrosion products, and other
<br />foreign matter, except for staining. Staining shall be limited to no more than 5 percent of each square inch of surface area and
<br />may consist of light shadows, slight streaks, or minor discoloration caused by stains of rust, stains of mill scale, or stains of
<br />previously applied paint. Before blast cleaning, visible deposits of oil or grease shall be removed by any of the methods
<br />specified in SSPC-SP 1 or other agreed upon methods. For complete instructions, refer to Joint Surface Preparation Standard
<br />SSPCSPIO/ NACE No.2.
<br />SSPC-SP11 - Power Tool Cleaning to Bare Metal: Metallic surfaces that are prepared according to this specification, when
<br />viewed without magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust, paint, oxide corrosion products,
<br />and other foreign matter. Slight residues of rust and paint may be left in the lower portions of pits if the original surface is
<br />pitted. Prior to power tool surface preparation, remove visible deposits of oil or grease by any of the methods specified in SSPC
<br />-SP 1, Solvent Cleaning, or other agreed upon methods. For complete instructions, refer to Steel Structures Paint Council
<br />Surface Preparation Specification No.11.
<br />SSPC-SP12 / NACE 5 - Surface Preparation and Cleaning of Metals by Waterjetting Prior to Recoating: High- and Ultra
<br />-High Pressure Water Jetting for Steel and Other Hard Materials This standard provides requirements for the use of high- and
<br />ultra-high pressure water jetting to achieve various degrees of surface cleanliness. This standard is limited in scope to the use of
<br />water only, without the addition of solid particles in the stream. For complete instructions, refer to Joint Surface Preparation
<br />Standard SSPC-SPI2/NACE No.5.
<br />SSPC-SP13 / NACE 6 or ICRI 03732 - Surface Preparation of Concrete: This standard gives requirements for surface
<br />preparation of concrete by mechanical, chemical, or thermal methods prior to the application of bonded protective coating or
<br />lining systems. The requirements of this standard are applicable to all types of cementitious surfaces including cast-in-place
<br />concrete floors and walls, precast slabs, masonry walls and shotcrete surfaces. An acceptable prepared concrete surface should
<br />be free of contaminants, laitance, loosely adhering concrete, and dust, and should provide a dry, sound, uniform substrate
<br />suitable for the application of protective coating or lining systems. Depending upon the desired finish and system, a block filler
<br />may be required. For complete instructions, refer to Joint Surface Preparation Standard SSPC-SP13/NACE No.6 or ICRI 03732
<br />SSPC-SP14 / NACE 8— Industrial Blast Cleaning: This standard gives requirements for industrial blast cleaning of
<br />unpainted or painted steel surfaces by the use of abrasives. This joint standard allows defined quantities of mill scale and/or old
<br />coating to remain on the surface. An industrial blast cleaned surface, when viewed without magnification, shall be free of all
<br />visible oil, grease, dust, and dirt. Traces of tightly adherent mill scale, rust, and coating residue are permitted to remain on 10%
<br />of each unit area of the surface. The traces of mill scale, rust, and coating shall be considered tightly adherent if they cannot be
<br />lifted with a dull putty knife. Shadows, streaks, and discolorations caused by stains of rust, stains of mill scale, and stains of
<br />previously applied coating may be present on the remainder of the surface.
<br />SSPC-SP16 Brush-Off Blast Cleaning of Coated and Uncoated Galvanized Steel, Stainless Steels, and Non-Ferrous
<br />Metals: This standard covers the requirements for brush-off blast cleaning of uncoated or coated metal surfaces other than
<br />carbon steel by the use of abrasives. These requirements include visual verification of the end condition of the surface and
<br />materials and procedures necessary to achieve and verify the end condition. A brush-off blast cleaned non-ferrous metal
<br />surface, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, metal oxides (corrosion products),
<br />and other foreign matter. Intact, tightly adherent coating is permitted to remain. A coating is considered tightly adherent if it
<br />cannot be removed by lifting with a dull putty knife.
<br />High- and Ultra-High Pressure Water Jetting for Steel and Other Hard Materials:
<br />SSPC-SP WJ-1/NACE WJ-1: Clean to Bare Substrate (WJ-1) is intended to be similar to the degree of surface cleanliness of
<br />SSPC-SP 5/NACE I, except that stains are permitted to remain on the surface. This standard is used when the objec-tive is to
<br />remove every trace of rust and other corrosion products, coating and mill scale.
<br />SSPC-SP WJ-2/NACE WJ-2: Very Thorough Cleaning (WJ-2) is intended to be similar to the degree of surface cleanliness of
<br />SSPC-SP 10/NACE 2, except that tightly adherent material, rather than only stains, is permitted to remain on the surface. This
<br />standard is used when the objec-tive is to remove almost all rust and other corrosion products, coating, and mill scale.
<br />SSPC-SP WJ-3/NACE WJ-3: Thorough Cleaning (WJ-3) is intended to be similar to the degree of surface cleanliness of
<br />SSPC-SP 10/NACE 2, except that tightly adherent material, rather than only stains, is permitted to remain on the surface. This
<br />standard is used when the objective is to remove much of the rust and other corrosion products, coating, and mil scale, leaving
<br />tightly adherent thin films.
<br />SSPC-SP WJ-4/NACE WJ-4: Light Cleaning (WJ-4) is intended to be similar to the degree of surface cleanli-ness of SSPC-
<br />SP 10/NACE 2, except that tightly adherent material, rather than only stains, is permitted to remain on the surface. This
<br />standard is used when the objective is to allow as much of the tightly adherent rust and other corro-sion products, coating, and
<br />mill scale to remain as possible, Discoloration of the surface may be present.
