SIST EN 666:1999

Overview

SIST EN 666:1999 is a European Standard developed by CEN that specifies the method for determining the degree of gelling in polyvinyl chloride (PVC) resilient floor coverings. Gelling refers to the extent to which PVC flooring materials undergo a gelation process, affecting their physical properties and durability. This standard is primarily intended for production control purposes, ensuring consistent quality and performance in the manufacture of resilient floor coverings.

Key Topics

• Determination of Gelling: SIST EN 666:1999 outlines a standardized procedure to measure the degree of gelling in PVC floor coverings, which is a critical indicator of the material’s stability and manufacturing consistency.
• Polyvinyl Chloride Floor Coverings: The standard specifically applies to resilient floor coverings made from PVC, a widely used material in commercial and residential flooring due to its durability and ease of maintenance.
• Quality Control in Production: The standard supports manufacturers in maintaining consistent product quality by providing a reliable testing method for gelling during floor covering production.
• Non-textile Floor Coverings: Categorized under ICS 97.150, this standard addresses non-textile resilient flooring products, differentiating from textile floor coverings often governed by other standards.

Applications

• Manufacturing Quality Assurance: By implementing SIST EN 666:1999, manufacturers can monitor and control the gelling level of PVC resilient floor coverings, ensuring the final product meets defined quality and performance criteria.
• Resilient Flooring Industry: This standard benefits producers, quality inspectors, and product developers involved in producing vinyl and other PVC-based flexible floorings.
• Product Development and Testing: Laboratories and research centers use this method to analyze new formulations of PVC floor coverings to optimize properties such as flexibility, wear resistance, and longevity.
• Regulatory Compliance: Adherence to this European Standard helps companies meet industry regulations and customer expectations, supporting product certification and market acceptance within Europe.
