ISO 24343-1:2007

Overview

ISO 24343-1:2007 is an international standard published by ISO (International Organization for Standardization) that provides a precise method for determining the residual indentation of resilient and laminate floor coverings. Residual indentation refers to the permanent deformation remaining after a floor covering is subjected to a constant load and then allowed to recover. This is a critical performance characteristic for flooring products, directly influencing their durability, comfort, and appearance retention in residential, commercial, and industrial environments.

By establishing a standardized procedure, ISO 24343-1:2007 ensures reliable and repeatable testing results. Manufacturers, quality control professionals, and specifiers in the flooring sector use this standard to assess product quality and compliance with market and regulatory requirements.

Key Topics

• Residual Indentation Definition: Difference between the initial thickness of the floor covering and its thickness measured after unloading and a defined recovery period.
• Test Method: Outlines the precise sample preparation, conditioning, use of a cylindrical indenter, load application, measurement techniques, and calculation of results.
• Apparatus Specifications: Details on the design and required tolerances for the indenter, loading device, comparator, and thickness measuring equipment, ensuring consistency across laboratories.
• Environmental Conditioning: Specifies strict temperature and humidity conditions for sample conditioning and testing.
• Reporting Requirements: Clear guidelines for the documentation of test results, including all relevant variables and deviations.

Applications

ISO 24343-1:2007 is essential for a wide range of stakeholders in the flooring industry:

• Product Development: Flooring manufacturers use the standard to develop new resilient and laminate products that meet global expectations for underfoot comfort and long-term aesthetics.
• Quality Assurance: Quality control teams apply the test to ensure production consistency and compliance with technical specifications or contractual agreements.
• Certification & Compliance: Independent laboratories and certification bodies rely on ISO 24343-1:2007 when verifying products for third-party certification or regulatory approval.
• Procurement: Specifiers and buyers reference residual indentation values to select floor coverings suitable for environments with expected static loads, such as offices, schools, and hospitals.
• Market Differentiation: Manufacturers can demonstrate superior performance and advertise compliance with ISO 24343-1 to gain a competitive advantage and build customer trust.

Related Standards

• ISO 24343-2 (Planned): Will address the determination of short term indentation in floor coverings.
• ISO/TC 219: The ISO technical committee responsible for standardization in the field of floor coverings.

Practical Value

Implementing ISO 24343-1:2007 advances product reliability, customer satisfaction, and regulatory compliance in resilient and laminate floor coverings. By using consistent testing for residual indentation, stakeholders can objectively compare products, ensure fitness for intended use, and support claims of quality and performance. This leads to safer, longer-lasting, and more appealing flooring solutions for various market sectors.
