RELATIVE HUMIDITY MEASUREMENT
There are two International Standard methods of
relative humidity measurement in flooring that can be
carried out with the Concrete Moisture Encounter X5
with the external Hygro-i2 probe attached:
(a) In-situ (below the surface of the slab) ASTM F2170
& BS 8201, 8203, 5325.
(b) RH Hood (on the surface of the floor slab) BS 8201,
8203, 5325.
(a) In-situ Relative Humidity Test Method – Guidelines.
Perform 3 per 100m
2
(1000ft
2
) and 1 per next 100m
2
.
Holes must be drilled dry and perpendicular (90˚), do
not use water for cooling or lubrication.
When drying is from the top only, it is recommended
that the hole should be drilled to approx 40% of the slab
thickness.
When drying is from both sides, it is recommended
that the slab should be drilled to approx 20% of slab
thickness.
A hole cleaning brush is often required to ensure the
drilled hole is free from any loose particles. A vacuum
should also be used to ensure the drilled hole is free
from any dust.
The user should always refer to national standard
guidelines for definitive and current procedure and
specifications.
