ISO 2094:1999

Overview

ISO 2094:1999 specifies a laboratory method to determine thickness loss of textile floor coverings under dynamic loading. The standard applies to all textile floor coverings with a level surface and construction, and describes a repeatable impact test that simulates compressive and vertical-shearing wear to quantify pile or total-thickness reduction over a stated number of impacts.

Key topics and technical requirements

• Test principle: A guided weight-piece with two steel feet repeatedly drops onto a clamped specimen while the steel base plate is slowly traversed to generate vertical shearing and compression across a defined area.
• Apparatus parameters (as given in the standard): weight-piece mass 1 279 g ± 13 g; drop height 63.5 mm ± 0.5 mm; impact interval 4.3 s ± 0.3 s; two rectangular feet (specified width, length and depth) separated by 38 mm ± 0.5 mm; base plate dimensions and traverse increments to produce ~25 impacts per cycle.
• Specimens and conditioning: Minimum two specimens per sample, cut ≈125 mm × 125 mm (ISO 1957 guidance), conditioned in a standard atmosphere (ISO 139) for at least 24 h. Pile specimens are brushed before testing.
• Measurements: Thickness measured before and after impacts using the method in ISO 1765 under a standard pressure of 2.0 kPa ± 0.2 kPa, to 0.1 mm precision. Typical measurement intervals: after 50, 100, 200 and 1 000 impacts (more impacts permitted). Results expressed as thickness loss (difference) and mean values.
• Reporting and repeatability: Record source/type of sample, atmosphere, procedures used, mean untreated thickness and mean thickness loss to 0.1 mm. If specimen means differ by more than 10%, repeat tests on two additional specimens.

Applications and who uses ISO 2094

• Flooring manufacturers: to quantify product durability and compare constructions (pile height, backing, yarns).
• Test laboratories and QA teams: standard method for routine quality control, acceptance testing and batch verification.
• Specifiers and procurement: objective data for performance-based selection of carpets and textile floor coverings for commercial, residential or institutional projects.
• R&D and product development: to evaluate design changes, materials or backing systems for improved resilience to dynamic wear.
• Standards bodies and certification schemes: as a referenced test in performance classifications or product declarations.
