Relative Humidity Testing (ASTM F2170)

Test #	Location	Depth (%)	Hole Depth (in)	Liner Set	Liner Duration (hrs)	Probe Set	RH (%)	Temp (°F)	Sensor Cal. Date	Actions

ASTM F2170 Standard: Internal relative humidity testing of concrete slabs. Tests must be conducted at 40% depth for slabs drying from top only, or 20% depth for slabs drying from top and bottom. Current standard requires minimum 24 hours from sleeve insertion to probe insertion time.

Moisture Vapor Emission Rate Testing (ASTM F1869)

Test #	Location Description	Initial Weight (g)	Final Weight (g)	Weight Gain (g)	Vent Time (hrs)	Test Duration (hrs)	Surface pH	MVER (lbs/1000ft²/24hrs)	Actions

ASTM F1869 Standard: Calcium Chloride testing for moisture vapor emission rate from concrete floor slabs. Test kits measure moisture emission over a 60-72 hour period.

Formula: MVER (lbs/1000ft²/24hrs) = Weight Gain (grams) × 118.932 / Test Duration (hours) [Source: Vapor Score]

Surface Testing (ASTM F2659)

Test #	Location Description	Surface MC (%)	Meter Type	Make/Model	Actions

Test #	Location Description	Depth (inches)	In Situ MC (%)	Meter Type	Make/Model	Method	Actions

ASTM F2659 Standard: Preliminary evaluation of comparative moisture content in concrete slabs using non-destructive electronic moisture meters. Surface readings measure near-surface conditions while in situ readings can assess moisture conditions at various depths within the slab.

Surface pH Testing

Test #	Location Description	Surface pH	Test Method	Actions

Surface pH Testing: Surface pH testing is performed to determine the alkalinity of the concrete surface. High pH levels (above 9) may affect adhesive performance and flooring material stability. Typical acceptable pH range for most flooring adhesives is between 7 and 9.
