SIST EN 13892-7:2003

Overview

SIST EN 13892-7:2003 is a European Standard developed by CEN that specifies a method to determine the wear resistance of screed materials combined with floor coverings against a loaded rolling wheel. This test focuses on assessing the durability of various screed types-including cementitious, calcium sulfate, asphalt, magnesite, and synthetic resin screeds-with applied polyvinyl chloride (PVC) floor coverings. The standard is essential for ensuring that floor screed systems can endure mechanical stresses from rolling loads without delamination or surface failure, supporting quality assurance in flooring installations.

Key Topics

• Scope and Purpose: Defines a test method for evaluating resistance to rolling wheel wear on molded screed specimens with floor covering overlays.
• Test Principle: The procedure applies repeated passages of a loaded swivel castor wheel over screed specimens in two perpendicular directions, inducing normal, shear, and torsional stresses.
• Test Rig and Apparatus:
  • Supporting table moves specimens under the rolling wheel with controlled stroke lengths and frequencies.
  • Swivel castor wheel designed per specified dimensions and load conditions ranging from 150 N to 550 N.
• Specimen Preparation:
  • Specimens are square slabs with minimum edge length of 350 mm and thickness ≥ 30 mm or applied on concrete substrates.
  • 1.5 mm thick PVC floor covering adhering to EN 649 and EN 660 standards is used.
• Test Procedure:
  • Testing performed at least 28 days after casting or once flooring manufacturer’s minimum curing time has been reached.
  • Loaded wheel cycles 10,000 times (~8 hours) over the test specimen.
  • Inspection for delamination includes drilling trials to verify adhesion.
• Result Expression:
  • Resistance is quantified by the maximum load sustainable without coating delamination (RWFC values: 150, 250, 350, 450, or 550 Newtons).
• Reporting Requirements:
  • Detailed test report essentials including specimen identification, preparation, test conditions, results, failure mode, and remarks.

Applications

SIST EN 13892-7:2003 is widely applicable in:

• Construction Industry: For the certification and quality control of screed materials used with resilient floor coverings, ensuring long-term performance in residential, commercial, and industrial buildings.
• Flooring Manufacturers and Suppliers: Assisting in product development, validating wear resistance claims, and complying with European product standards.
• Testing Laboratories: Providing a standardized, reproducible method for wear resistance evaluation, enabling consistent product assessment across markets.
• Building Designers and Specifiers: Informing selection of suitable screed materials and floor coverings that withstand mechanical fatigue, especially in high-traffic or rolling load environments.
• Regulatory Compliance: Supporting harmonization with other European standards related to screed materials and floor coverings, for seamless integration into building codes.
