Описание (английский):

ISO 4918:2016 specifies methods for determining the change of appearance and stability of a textile floor covering or any damage caused by detachment of layers, opening of joints, or crazing of a resilient or laminate floor covering under the movement of a castor chair.

Abstract

Overview

Key topics and technical requirements

Scope: Test procedures for textile, resilient and laminate floor coverings to assess appearance retention, colour change and structural damage under castor movement.
Test principle: A specimen is subjected to a prescribed number of castor cycles using three castors moving in epicyclical paths with starts, stops and direction changes.
Specified cycle counts (textile):
- Test A (appearance): assessment after 5 000 and 25 000 cycles (per ISO 9405).
- Test B (colour change): assessment after 750 cycles using grey scales.
- Test C (deterioration): assessment after 10 000 or 25 000 cycles.
Resilient & laminate assessment: Focus on detachment of layers, opening of joints or crazing; specific criteria for click-joint floating installations are included.
Apparatus details: Typical bench includes a rotating test platform (minimum 800 mm diameter), a castor assembly offset and three castors mounted at 120° intervals; tested area approx. 0.3 m². Loading and castor verification procedures are specified.
Conditioning, sampling and mounting: Separate requirements for textile versus resilient/laminate specimens; conditioning per ISO atmospheres (e.g., ISO 139).
Assessment & reporting: Defined assessment methods, calculations and mandatory elements for the test report.

Applications and who uses it

Flooring manufacturers use EN ISO 4918 to validate product durability against office-chair traffic and to support product claims.
Independent test laboratories apply the standard to provide accredited castor-chair test results.
Specifiers, architects and facility managers use test data to select suitable floor coverings for offices, public spaces and contract environments.
Procurement and quality assurance teams reference the standard when writing performance specifications or acceptance criteria.

Keywords: castor chair test, EN ISO 4918:2021, ISO 4918, floor coverings test, resilient floor coverings, textile floor coverings, laminate floor coverings, appearance retention, castor cycles.
