Overview
ISO 11857:1999 establishes a standardized method for determining the resistance of textile floor coverings to delamination. This International Standard is applicable to all types of textile floor coverings that use a secondary or foam backing. The procedure defines how to measure the force required to separate the plies, providing valuable data for quality control during production. Although results obtained via this method are not a reliable prediction of in-use performance, they are essential for maintaining consistent product quality and for identifying manufacturing issues.
Key Topics
- Delamination resistance testing: The standard focuses on measuring the force needed to separate layers in textile floor coverings.
- Applicable products: All textile floor coverings with secondary or foam backings, including carpets and rugs.
- Test methodology: Utilizes a tensile testing machine with specific settings to ensure consistent measurement.
- Specimen preparation: Details steps for sampling, specimen cutting, conditioning, and the application of adhesive tape for foam-backed products.
- Conditioning and testing environment: Specifies standard atmospheric conditions (20°C ± 2°C, 65% RH ± 2%) as per ISO 139 to ensure repeatable results.
- Calculation and reporting: Describes how to interpret test data, calculate average loads, and compile comprehensive test reports.
Applications
Textile floor covering manufacturers:
ISO 11857:1999 is widely used in manufacturing environments for quality assurance. By assessing the force required to separate backing layers, manufacturers can quickly detect issues related to bonding processes, adhesive quality, or material compatibility.
Product development and R&D:
Development teams use delamination resistance data when designing new products or selecting backing systems. Consistent application of this standard helps in comparing different backing types or adhesives.
Third-party testing and certification:
Independent laboratories and certifying bodies rely on ISO 11857:1999 to provide standard, comparable results for textile floor covering samples.
Procurement and vendor qualification:
Buyers and procurement professionals use delamination resistance values as part of their quality criteria for supplier selection, especially when secondary or foam backings are specified.
