Overview
EN 1875-3:2023 - "Rubber- or plastics-coated fabrics - Determination of tear strength - Part 3: Trapezoidal method (five-highest-peak calculation)" - is a CEN standard that specifies the test conditions and procedure for measuring the tear strength of coated fabrics using a trapezoidal specimen and a tensile testing machine. The standard covers specimen preparation, conditioning, test apparatus and settings, data collection requirements, result calculation (five-highest-peak calculation) and reporting rules. It supersedes EN 1875-3:1997 and is intended for both routine quality control and comparative performance testing of rubber- or plastics-coated textiles.
Key Topics and Requirements
- Specimen geometry and sampling
- Ten specimens per sample: 150 ± 1 mm long × 75 ± 1 mm wide.
- Five specimens tested in the longitudinal direction and five in the transverse direction.
- Initiating incision (15 mm) and marked attachment positions as shown in the standard’s figure.
- Conditioning and atmosphere
- Default conditioning in climate B: 23 ± 2 °C and 50 ± 5% RH.
- Recommended conditioning durations: minimum 16 h for one-side coated textiles, 24 h for two-side coated textiles. Exceptions allowed for treated samples (e.g., dipped).
- Apparatus and test parameters
- Use a constant rate of extension (CRE) tensile testing machine compliant with EN ISO 1421 and EN ISO 7500-1.
- Data acquisition frequency: ≥ 8 Hz (not less than 8 samples per second) for computer-aided recording.
- Rate of jaw traverse: 100 ± 10 mm/min.
- Jaw/clamp width: ≥ 75 mm (no slippage).
- Calculation (five-highest-peak method)
- For each specimen, identify peaks on the force–displacement trace and compute the average of the five highest peak forces (newtons).
- Compute the arithmetic mean of specimen averages for each direction; round to three significant digits and report mean tear force to 0.1 N.
- Acceptance and reporting
- Test valid only if no slippage, no coating/base separation (delamination), and tear propagates almost perpendicular to specimen length. Deviations must be recorded; unusually oriented tears (>45°) may be flagged or rejected.
Applications and Users
- Practical uses: quality control, product development, compliance verification, material comparisons and supplier qualification for coated fabrics used in tarpaulins, inflatable structures, protective garments, automotive and industrial coverings.
- Typical users: textile testing laboratories, coating manufacturers, product designers, procurement/specification engineers, certification bodies and R&D teams focused on coated textile durability and tear resistance.

Introduction
Tearing is amongst the more usual ways of destruction for many thin and flexible materials. Knowledge
of the resistance of these materials to this type of behaviour is therefore very important. In practice,
tearing can result from very different circumstances: hence the large number of test methods that have
been developed in order to predict the behaviour of the materials in various situations.
This document forms part of a European Standard on tear resistance of coated fabrics as follows
• EN ISO 4674-1, Rubber- or plastics-coated fabrics - Determination of tear resistance - Part 1: Constant
rate of tear methods (ISO 4674-1);
• EN ISO 4674-2, Rubber- or plastics-coated fabrics - Determination of tear resistance- Part 2: Ballistic
pendulum method (ISO 4674-2);
• EN 1875-3, Rubber- or plastics-coated fabrics - Determination of tear strength - Part 3: Trapezoidal
method (five-highest-peak calculation).
The first part describes two methods using a tensile testing machine at a constant rate of elongation. The
second part describes a dynamic method using the kinetic energy of a falling pendulum. For these two
parts, tearing propagates in a direction parallel to the applied force. The third part uses a trapezoidal test
piece, where tearing propagates in a direction perpendicular to the applied force.
Trapezoidal method should logically be classified with the constant speed methods but is generally
considered apart owing to the direction of propagation.
Attention is drawn to the fact that the results of the different methods cannot be compared, owing to the
differences of principle.
1 Scope
This document specifies test conditions and the procedure to be followed for determining the tear
strength of a trapezoidal specimen of a rubber- or plastics-coated fabric, using a tensile testing machine.
This test can be carried out:
• either on test specimens conditioned in reference atmospheres; or
• on test specimens which have been subjected to any necessary treatment for the application
considered, for example dipping.
