• BSSPC-SP 6 / NACE No. 3
• CSSPC-SP 10 / NACE No. 2
• DSSPC-SP 7 / NACE No. 4

SSPC-SP 1 addresses which aspect of surface preparation?

• ASolvent cleaning to remove oil, grease, and soluble contaminants
• BPower tool cleaning

A coating specification calls for a 2-3 mil surface profile. Which method per ASTM D4417 uses replica tape pressed into the profile and read with a micrometer?

• AMethod A – visual comparator
• BMethod B – depth micrometer
• CMethod C – replica tape (Testex)
• DMethod D – dye penetrant

When reading Testex Coarse replica tape with a spring micrometer, the displayed value must be corrected by subtracting what thickness to obtain the true surface profile?

• A1 mil (25 μm)
• B2 mils (50 μm)
• C3 mils (75 μm)
• DNo correction is required

Per the Society for Protective Coatings standards, 'flash rust' on a blasted surface refers to:

• ARust bloom that develops rapidly on a freshly blasted steel surface due to moisture
• BRust present before blasting began
• CRust under the existing coating
• DA type of rust inhibitor applied after blasting

Which standard provides photographic reference points for the initial rust condition (A, B, C, D) of uncoated steel before surface preparation?

• ASSPC-VIS 1
• BSSPC-PA 2
• CISO 8501-1
• DASTM D4414

What is the primary disadvantage of using silica sand as a blast abrasive?

• AIt is too soft to create a profile
• BIt generates respirable crystalline silica dust, a health hazard
• CIt cannot clean rust
• DIt is prohibitively expensive

A specification requires SSPC-SP 6 / NACE No. 3 Commercial Blast Cleaning. What is the maximum percentage of the surface that may have staining or residual matter per unit area?

• A5%
• B10%
• C33%
• D67%

Per SSPC-AB 1, abrasives used for blast cleaning must meet specifications for which contaminant that can cause premature coating failure?

• AMoisture content only
• BWater-soluble contaminants (conductivity)
• CColor of the abrasive
• DAbrasive shape

Soluble salts on a blasted substrate are commonly tested using which field method?

• ABresle patch with conductivity meter
• BpH indicator paper
• CWet film gauge
• DPull-off adhesion tester

Peak count (peaks per inch or per cm) is a profile characteristic that influences:

• AFinal dry film color
• BCoating adhesion and mechanical interlocking
• CCure time of the coating
• DVOC content of the coating

What is the correct sequence of surface preparation steps for a carbon steel substrate with oil contamination and mill scale?

• AAbrasive blast, then solvent clean
• BSolvent clean per SSPC-SP 1, then abrasive blast to the specified grade
• CPower tool clean only
• DWire brush, then paint directly

SSPC-SP 11 specifies which of the following?

• APower tool cleaning to bare metal with a minimum surface profile
• BWater jetting with potable water
• CHand tool cleaning only
• DBrush-off blast cleaning

When using a hardened steel profile comparator (Keane-Tator), the inspector compares the surface texture against:

• ASegments machined to known average profile depths
• BColored coating chips
• CStandard weight samples
• DPhotographs of rust grades

Which SSPC/NACE water jetting standard corresponds to the cleanest level, removing all previously existing coatings, mill scale, and rust?

• ASSPC-SP WJ-4 / NACE WJ-4
• BSSPC-SP WJ-3 / NACE WJ-3
• CSSPC-SP WJ-2 / NACE WJ-2
• DSSPC-SP WJ-1 / NACE WJ-1

Which contaminant test is used to detect residual oil or grease on a cleaned steel surface?

• AWater break test
• BChloride test strip
• CBresle patch
• DTooke gauge

For immersion-service coatings, surface soluble chloride contamination on the prepared substrate is typically limited to what order of magnitude?

• A50 µg/cm² chloride
• BLess than 7 µg/cm² chloride (or equivalent)
• C500 µg/cm² chloride
• DNo limit exists
