Overview
EN 13892-9:2025 - Methods of test for screed materials, Part 9: Dimensional stability is a CEN standard that specifies a laboratory method to measure shrinkage and swelling (dimensional stability) of screed materials. It applies to cementitious, calcium sulphate, magnesite and synthetic resin screeds prepared in accordance with EN 13892-1. The method uses a 1 000 mm curling profile apparatus to record unrestrained horizontal length changes from the moment the mould is filled until steady-state is reached.
Key topics and requirements
- Scope: Dimensional stability (shrinkage and swelling) of screed materials made per EN 13892-1.
- Apparatus: Curling profile mould (1 000 mm effective length, 100 mm width, 50 mm depth typical) with stainless-steel dowels, striker plate and a length variation sensor.
- Sensor accuracy: Length sensor must measure ≥5 mm travel with accuracy ≤ 0.003 mm.
- Test climate: Standard laboratory conditions - (23 ± 2) °C and (50 ± 5) % RH for the full procedure.
- Specimen preparation: Mix and cast per EN 13892-1; determine consistency within 5 minutes (per EN 13454-2); compact into mould lined with polyethylene and polychloroprene sheet.
- Measurement timing: Monitoring starts immediately after mould filling and spacer removal; change in length recorded continuously at 10-minute intervals (new in 2025).
- Duration: For screeds with >10% cement in binder, record length variations for a minimum of 90 days; end of length change is defined when 5‑day monitored change differs by <3% from obtained shrinkage.
- Moisture content: Determined after end of length change by drying (>300 g sample) to constant mass; drying temperatures: cementitious and magnesite (105 ± 2) °C, calcium sulphate (40 ± 2) °C.
- Reporting: Full length-change/time curve, start/max/min/end points, shrinkage/swelling values (µm/m), moisture content and full test details.
Applications
- Performance verification of floor screed formulations (shrinkage-controlled or low-shrinkage mixes).
- Quality control in production and R&D for manufacturers of screed binders and premixes.
- Independent testing laboratories validating product declarations and compliance with EN 13813.
- Specifiers, architects and contractors assessing risk of curling, cracking or movement in floor systems.
- Product certification and technical dossiers for construction product standards.

5 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), see Formula (1):
