4 Principle
This test method measures the unrestrained linear movement, called dimensional stability (i.e.
shrinkage and swelling), of screed materials in a 1 000 mm curling profile apparatus. A special feature
of this test method is the earliest possible commencement of measurements.
Dimensional stability is measured on screed materials made in accordance with EN 13892-1.
Irrespective of the consistency of the screed material, monitoring of horizontal length change
commences directly after the mould is filled. When measurements of length reach a steady-state, the
monitoring process ends.
The apparatus monitors the change in length of the specimen over time.
In general, the shrinkage predominates the dimensional stability. In this case, the dimensional stability
is calculated by comparing the difference between the measured local maximum length and the
measured length at steady-state (end of length change):

If the swelling predominates the dimensional stability is calculated by comparing the difference

6 Curling profile apparatus
The curling profile apparatus, shown in Figure 1, features a stainless steel, distortion-resistant mould
50 mm in depth and 100 mm in width with an effective specimen length of 1 000 mm.
At one end of the mould, the specimen is restrained horizontally and vertically by two stainless steel
dowels cast within the specimen whilst the opposite end is unrestrained and th
