magnification the surface shall be free from visible oil, grease, dust, dirt, mill scale, rust, coating, oxides,
corrosion products, and other foreign matter. Random staining shall be limited to no more than 5% of
each unit area of surface and may consist of lighshadows, slight streaks, or minor discolorations caused
by stains of rust, stains of mill scale or stains of previously applied coatings.
NACE #3/SSPC-SP-6 - CORRECT ANSWER COMMERCIAL BLAST CLEANING. When viewed without
magnification the surface shall be free from visible oil, grease, dust, dirt, mill scale, rust, coating, oxides,
corrosion products, and other foreign matter. Random staining shall be limited to no more than 33% of
each unit area of surface and may consist of light shadows, slight streaks, or minor discolorations caused
by stains of rust, stains of mill scale or stains of previously applied coatings.
NACE #8/SSPC-SP14 - CORRECT ANSWER INDUSTRIAL BLAST CLEANING. When viewed without
magnification the surface shall be free from visible oil, grease, dust, and dirt. Traces of light adherent
mill scale, rust, and coating residues are allowed to remain on 10% of each unit area of the surface if the
are randomly distributed. The traces of mill scale, rust and coating are considered tightly adherent if
they cannot be removed by lifting with a dull putty knife. Shadows, streaks and discolorations caused by
stains of rust, stains of mill scale, or stains of previously applied coatings may be present on the
remainder of the surface.
NACE #4/SSPC-SP-7 - CORRECT ANSWER BRUSH-OFF BLAST CLEANING. When viewed without
magnification the surface shall be free from visible oil, grease, dust, dirt, loose mill scale, loose rust, and
loose coating. Tightly adherent mill scale, rust and coating may remain on the surface. Mill scale, rust
and coating are considered tightly adherent if they cannot be removed by lifting a dull putty knife.
SA 3 - CORRECT ANSWER BLAST CLEANING TO VISUALLY CLEAN STEEL. When viewed without
magnification the surface shall be free from visible oil, grease, dust dirt, mill scale, rust , coating, oxides,
corrosion products and other foreign matter. It shall have a uniform metallic color
,SA 2 1/2 - CORRECT ANSWER VERY THOROUGH BLAST CLEANING. When viewed without magnification
the surface shall be free from visible oil, grease, dust dirt, mill scale, rust , coating, oxides, corrosion
products and other foreign matter. Any remaining traces of contamination will show only as slight stains
in the form of spots or stripes.
SA 2 - CORRECT ANSWER THOROUGH BLAST CLEANING. When viewed without magnification the surface
shall be free from visible oil, grease, dust dirt, mill scale, rust , coating, oxides, corrosion products and
other foreign matter. Any residual contamination shall be firmly adhering
SA 1 - CORRECT ANSWER LIGHT BLAST CLEANING. When viewed without magnification the surface shall
be free from visible oil, grease, dust, dirt, mill scale, rust , paint coatings, and foreign matter.
ST 2 - CORRECT ANSWER THOROUGH HAND AND POWER TOOL CLEANING. When viewed without
magnification the surface shall be free from visible oil, grease, dust, dirt, and from poorly adhering mill
scale, rust , paint coatings, and foreign matter
ST 3 - CORRECT ANSWER VERY THOROUGH HAND AND POWER TOOL CLEANING. Same as ST 2, but the
surface shall be treated much more thoroughly to give a metallic sheen arising from the the metallic
substrate. When viewed without magnification the surface shall be free from visible oil, grease, dust,
dirt, and from poorly adhering mill scale, rust , paint coatings, and foreign matter
SSPC-SP 2 - CORRECT ANSWER HAND TOOL CLEANING. Hand tool cleaning removes all loose mill scale,
rest, paint, and other detrimental foreign matter. It is not intended that adherent mill scale, rust and
paint be removed by this process. Mill scale, rust, and paint are considered adherent if they cannot be
removed with a dull putty knife.
SSOC-SP 3 - CORRECT ANSWER POWER TOOL CLEANING. Power tool cleaning removes all loose mill
scale, rest, paint, and other detrimental foreign matter. It is not intended that adherent mill scale, rust
and paint be removed by this process. Mill scale, rust, and paint are considered adherent if they cannot
be removed with a dull putty knife
SSPC-SP 15 - CORRECT ANSWER COMMERCIAL GRADE POWER TOOL CLEANING. A commercial grade
power tool cleaned surface when viewed without magnification the surface shall be free from visible oil,
grease, dust dirt, mill scale, rust , coating, oxides, corrosion products and other foreign material, except
as noted in Section 2.2 of the standard. Random staining shall be limited to no more than 33% of each
unit area of surface. Staining may consist of light shadows, slight streaks, or minor discolorations caused
,by rust, mill scale, or previously applied coatings. Slight residues of rest and paint may also be left in the
bottom of the pits if the original surface is pitted.
SSPC-SP 11 - CORRECT ANSWER POWER TOOL CLEANING TO BARE METAL. A steel surface cleaned with
power tools to bare metal when viewed without magnification the surface shall be free from visible oil,
grease, dust dirt, mill scale, rust , coating, oxides, corrosion products and other foreign matter. Slight
residues of rust and paint may also be left in the bottom of the pits if the original surface is pitted. The
surface profile roughness shall be a minimum of 1.o mil as measured in accordance with Method C of
ASTM D4417 or other mutually agreed upon method. The peaks and valleys on the surface shall form a
continuous pattern with no smooth, unprofiled spots in between.
Cathode - CORRECT ANSWER More noble region where electrons are consumed. Reduction occurs at the
cathode
Anode - CORRECT ANSWER Part of the metal that corrodes. Oxidation occurs at the anode
Return Path (Metallic Pathway) - CORRECT ANSWER Connects cathode and anode and allows passage of
electrons generated at the anode to the cathode
Electrolyte - CORRECT ANSWER Medium that conducts ionic (rather than electronic) current
Negative Electrode - CORRECT ANSWER Zinc case which corresponds to the anode in a corrosion cell
