Determination of thickness
Using the micrometer, calliper gauge or any other equivalent tool, measure the thickness at a distance of 20
mm from the edges of the surface layer, at points located in each corner and in the middle of each long side
(only four corner points if length < 600 mm)

Determination of length
Using the appropriate calliper gauge or any other equivalent tool, measure the length of the surface layer
along two lines parallel to the axis of the test specimen, at a distance of 20 mm from the long sides

Determination of width
Using the appropriate calliper gauge or any other equivalent tool, measure the width , along two lines
parallel to the sides of the surface layer, at a distance of 20 mm from the sides, and in the middle for elements
with a length greater than 600 mm

Place one side of the square against one long side of the surface layer of the element. Using the thickness
gauges, determine the maximum deviation from square q at the small side. Repeat the procedure on the

Determine the initial thickness of the test specimens perpendicular on the extreme edges at the six points
indicated in Figure G.2. Place the two test specimens in the water bath as illustrated in Figure G.3. Remove
the test specimens after 24 h ± 15 min, and dry them with a towel. Determine the final thickness of the
test specimens perpendicular on the extreme edges at the same six measuring points.
