Methods of test for screed materials - Part 4: Determination of wear resistance-BCA

This European Standard specifies a method for determining the wear resistance of test specimens made from cementitious- or synthetic resin screed material or optionally for other screed materials. The method is also suitable for floor screeds.

Méthodes d'essai des matériaux pour chapes - Partie 4: Détermination de la résistance a l'usure BCA

La présente Norme européenne spécifie une méthode de détermination de la résistance à l'usure d'éprouvette d'essai faite à partir de matériaux pour chapes à base de ciment ou de résine synthétique ou, facultativement, à base d'autres matériaux pour chapes. La méthode convient également pour les éprouvettes de mortiers durci découpées dans une chape.

Overview

EN 13892-4:2002 defines a laboratory test method for assessing the wear resistance (BCA) of screed materials. Published by CEN, the standard covers cementitious and synthetic-resin screeds (and can be applied optionally to other screed types) and is suitable for both screed laboratory specimens and in‑situ floor screeds. The method quantifies surface wear by measuring the mean depth of material removed by a rotating three‑wheel abrasion head.

Key topics and requirements

• Scope: Test applies to cementitious- or synthetic resin‑based screed materials and floor screeds.
• Specimens: Wear resistance is measured on three specimens prepared per EN 13892-1. Minimum slab size is 500 mm edge and 50 mm thickness; thinner screeds may be applied onto a concrete substrate.
• Apparatus:
  • BCA abrasion test machine with an abrasion head carrying three hardened steel wheels mounted on a circular plate (nominal wheel track diameter 225 ± 1 mm).
  • Total load on wheels: 65.0 ± 0.5 kg (weights fixed to circular plate).
  • Wheel specification: nominal diameter 76 mm (minimum 73 mm), width 20.0–20.1 mm, specified hardness (tool steel heat treatment described).
  • Motor speed: 180 ± 15 min⁻¹, test for (2850 ± 10) revolutions (≈15 minutes).
• Measurements:
  • Depth gauge readable to 10 µm with feet positioned to straddle the wheel track; initial shim of 1.50–2.00 mm used to set the zero position.
  • Eight measurement positions are recorded before (do) and after (dw) the test.
  • Wear resistance AR = dw − do, reported to the nearest 10 µm; negative values recorded as zero.
• Procedure notes: Machine is pinned to the specimen to prevent lateral movement; brushing/vacuuming removes debris. Tests should be stopped if excessive vibration or substrate exposure occurs and reported.

Applications and users

• Who uses it: materials and product test laboratories, screed and flooring manufacturers, quality control departments, construction specifiers, and independent certification bodies.
• Practical uses:
  • Compare abrasion performance of screed formulations (cementitious vs resin).
  • Verify compliance with project specifications and performance claims.
  • Support product development, quality assurance and durability assessments for high‑traffic floors (industrial, commercial, public buildings).
