Overview
SIST EN 688:2026 - Resilient Floor Coverings: Specification for Corklinoleum sets out standardized requirements for the characteristics and performance of corklinoleum floors supplied in roll form. This standard, developed by the Slovenian Institute for Standardization (SIST), ensures that corklinoleum products meet criteria for durability, safety, and quality, supporting both manufacturers and consumers in making informed choices. Corklinoleum, a distinctive resilient floor covering, consists of a blend of linoleum cement and granulated cork, offering underfoot comfort and sound reduction.
Notably, SIST EN 688:2026 clarifies the difference between genuine linoleum and other materials, excluding products based on PVC or rubber. This document incorporates a robust classification system based on the intensity of use, referencing EN ISO 10874, to guide users in selecting the appropriate flooring for domestic, commercial, and specialized environments.
Key Topics
- Product Composition: Corklinoleum is defined by a homogeneous mixture of linoleum cement and cork granules, with additional pigments and fillers, calendared onto a carrier or fibrous backing, then oxidatively cured.
- Performance Requirements: The standard specifies criteria such as:
- Thickness and Density: Defined tolerances for nominal values.
- Mass per Unit Area: Strict allowances to ensure consistency.
- Flexibility: Resistance to cracking when bent to specified radii.
- Residual Indentation: Limits for deformation under static load.
- Colour Fastness to Light: Minimum levels to ensure lasting appearance.
- Classification System: Floors are classified by intensity of use (e.g., domestic moderate, domestic general, commercial moderate) according to EN ISO 10874, helping users select coverings offering the necessary service life and performance.
- Marking Requirements: Products and packaging must be clearly labelled with standard reference, manufacturer, product details, batch numbers, and class symbols, supporting traceability and informed purchase decisions.
- Optional Properties: Guidance on optional tests for electrical resistance, electrostatic propensity, stain resistance, and impact sound reduction, addressing specialized application needs.
Applications
Corklinoleum floor coverings are widely specified for environments where durability, comfort, and sustainable materials matter. Typical applications include:
- Residential Spaces: Living areas, kitchens, and bedrooms benefit from the underfoot comfort and acoustic dampening that corklinoleum provides.
- Commercial Areas: Offices, classrooms, corridors, and retail environments utilize corklinoleum's resilience and ease of maintenance.
- Healthcare and Institutional Settings: Thanks to its hygienic surfaces and comfort, corklinoleum is suitable for clinics, schools, and public buildings.
- Eco-Friendly Projects: Corklinoleum is a natural material, making it an attractive option for sustainable building initiatives.
The use of the classification system ensures that users can select floor coverings rated for the intensity of expected foot traffic, optimizing service life and reducing maintenance costs.
