Sample Arizona ROC CR-8 Floor Covering Practice Questions

Try these sample questions to test your Arizona ROC CR-8 Floor Covering exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under ASTM F2170, when performing in-situ relative humidity (RH) testing on a 6-inch thick concrete slab on grade that is drying from one side only, to what depth must the test hole be drilled?
A.1.2 inches (20% of slab thickness)
B.2.4 inches (40% of slab thickness)
C.3.0 inches (50% of slab thickness)
D.4.5 inches (75% of slab thickness)
Explanation: ASTM F2170 specifies that for concrete slabs drying from one side (such as a slab on grade with a vapor retarder below), in-situ probes must be installed at a depth equal to 40% of the total slab thickness. For a 6-inch slab, 40% depth equals 2.4 inches. This depth represents the internal moisture level that will equilibrate throughout the slab after flooring installation.
2According to ASTM F2170, what is the required probe hole drilling depth for a 5-inch thick elevated concrete slab drying from both the top and bottom sides?
A.1.0 inch (20% of slab thickness)
B.2.0 inches (40% of slab thickness)
C.2.5 inches (50% of slab thickness)
D.3.75 inches (75% of slab thickness)
Explanation: When an elevated concrete slab is exposed to air on both top and bottom surfaces, moisture evaporates from both directions. ASTM F2170 requires drilling to 20% of the slab thickness for two-sided drying. For a 5-inch slab, 20% of 5 inches is 1.0 inch.
3After drilling test holes and inserting plastic sleeves into a concrete slab per ASTM F2170, what is the minimum required equilibration period before inserting probes and taking official relative humidity readings?
A.4 hours
B.12 hours
C.24 hours
D.72 hours
Explanation: Under the current ASTM F2170 standard revision, in-situ probe sleeves must be allowed to equilibrate for a minimum of 24 hours after hole drilling and sleeve insertion before taking official relative humidity readings. This ensures that friction heat from drilling dissipates and moisture within the hole reaches equilibrium with the surrounding concrete matrix.
4Per ASTM F1869, what is the exact duration range that an anhydrous calcium chloride test kit must remain sealed to the concrete subfloor to measure Moisture Vapor Emission Rate (MVER)?
A.12 to 24 hours
B.24 to 48 hours
C.60 to 72 hours
D.84 to 96 hours
Explanation: ASTM F1869 mandates that anhydrous calcium chloride test kits must be left in place under a sealed transparent dome for a minimum of 60 hours up to a maximum of 72 hours. The weight gain of the calcium chloride over this exact time frame is converted into lbs of water vapor per 1,000 sq ft per 24 hours.
5What is the standard baseline maximum allowable Moisture Vapor Emission Rate (MVER) per ASTM F1869 for standard vinyl composition tile (VCT) installations using traditional water-based acrylic adhesives without moisture mitigation?
A.1.0 lb / 1,000 sq ft / 24 hours
B.3.0 lbs / 1,000 sq ft / 24 hours
C.5.0 lbs / 1,000 sq ft / 24 hours
D.8.0 lbs / 1,000 sq ft / 24 hours
Explanation: The traditional industry baseline maximum allowable MVER for standard resilient flooring adhesives (such as water-based acrylic VCT adhesives) is 3.0 lbs per 1,000 sq ft per 24 hours. Emissions exceeding 3.0 lbs require specialized moisture mitigation systems or high-moisture resistant adhesives.
6You are preparing to perform ASTM F1869 Calcium Chloride moisture testing on a 6,500 square foot commercial concrete floor slab. What is the minimum number of test kits required?
A.6 kits
B.7 kits
C.9 kits
D.12 kits
Explanation: ASTM F1869 requires 3 test kits for the first 1,000 square feet of slab area, plus 1 additional test kit for each additional 1,000 square feet (or fraction thereof). For 6,500 sq ft: First 1,000 sq ft = 3 kits. Remaining 5,500 sq ft = 6 additional kits (rounding up for fractions). Total = 3 + 6 = 9 test kits.
7Per ASTM F710, how is concrete surface pH tested prior to resilient flooring installation, and what is the typical acceptable pH range for standard water-based adhesives?
A.Apply phenolphthalein directly to dry concrete; acceptable pH is 4.0 to 6.0
B.Place distilled water drops on clean concrete, wait 60 seconds, use pH strip; acceptable pH is 7.0 to 9.0
C.Scrape concrete dust into acid solution; acceptable pH is 10.0 to 13.0
D.Drill a 1-inch hole and insert electronic pH probe; acceptable pH is 5.0 to 7.0
Explanation: ASTM F710 specifies placing drops of distilled water on a clean, abraded concrete surface, waiting 60 seconds, and testing the liquid with a calibrated pH paper strip or digital meter. Standard resilient adhesives typically require a concrete surface pH between 7.0 and 9.0 (some modern high-tack formulations allow up to 10.0 or 11.0).
8What is the minimum 28-day compressive strength required for cementitious self-leveling underlayment installed over concrete in commercial heavy-traffic floor applications per ASTM F710?
A.1,200 psi
B.2,000 psi
C.3,000 psi
D.5,000 psi
Explanation: ASTM F710 and resilient floor manufacturers mandate that cementitious underlayments used in commercial installations must achieve a minimum compressive strength of 3,000 psi at 28 days to withstand heavy rolling loads, hospital beds, and forklift traffic without indentation or crushing.
9When preparing a subfloor for glue-down luxury vinyl tile (LVT) or direct-glue hardwood, what is the maximum allowable surface variation using a 10-foot straightedge?
A.1/16 inch in 10 feet
B.3/16 inch in 10 feet
C.3/8 inch in 10 feet
D.1/2 inch in 10 feet
Explanation: Standard resilient and hardwood flooring industry guidelines (including ASTM F710 and NWFA) specify a maximum subfloor flatness variation of 3/16 inch in 10 feet (or 1/8 inch in 6 feet). High spots must be ground down and low spots filled with approved skim coat or leveling patch.
10Which surface preparation method is recommended to remove concrete curing compounds, laitance, and sealers to achieve an ICRI Concrete Surface Profile (CSP) of 3 to 5 prior to applying a heavy moisture mitigation epoxy?
A.Acid etching with muriatic acid
B.Shot blasting
C.Solvent wiping with mineral spirits
D.Pressure washing with cold water
Explanation: Shot blasting mechanically abrades the concrete surface by propelling steel shot at high velocity, efficiently removing laitance, sealers, and contaminants to create a textured ICRI CSP 3 to 5 profile necessary for mechanical bonding of thick epoxy moisture mitigation membranes.

Arizona ROC CR-8 Floor Covering Study Tips from Top Performers

1Memorize ASTM F2170 probe depth rules: 40% of slab thickness for slabs drying from one side (slab on grade), and 20% depth for slabs drying from both sides (elevated metal deck).
2Know the ASTM F1869 test kit calculation: minimum 3 test kits for the first 1,000 sq ft, plus 1 additional kit for each additional 1,000 sq ft of slab area.
3Review CRI 104/105 carpet power stretching rules: carpet MUST be power stretched 1% to 1.5% in both length and width; knee kickers are strictly for positioning/hooking, not stretching.
4Understand NWFA solid hardwood acclimation and moisture rules: wood MC must be within 4% of subfloor MC for solid strip (< 3" wide) and within 2% for wide plank (>= 3" wide).
5Study OSHA 1926.1153 Respirable Crystalline Silica Table 1 requirements for concrete floor grinding: handheld grinders require integrated dust shrouds connected to HEPA dust extractors.
