Full title and description

ISO 24339:2006 — Laminate and textile floor coverings — Determination of dimensional variations after exposure to humid and dry climate conditions. This International Standard defines a laboratory procedure to assess dimensional stability and related dimensional effects (including flatness and joint/opening behaviour for laminate products) when floor coverings are exposed to moderate humid and dry climatic cycles.

Abstract

ISO 24339:2006 specifies test conditioning, sample preparation and measurement methods to determine dimensional changes of laminate and textile floor coverings after exposure to controlled humid and dry climate conditions. The standard describes procedures for measuring linear and area changes and includes subclauses addressing flatness, openings between elements and height differences between elements that apply specifically to laminated floor coverings. It is intended as a reproducible laboratory method for manufacturers, test laboratories and specifiers.

Scope

This standard provides a method to determine the capability of laminate and textile floor coverings to withstand exposure to moderate humid and dry climate conditions. It covers sample selection and preparation, conditioning cycles, measurement of dimensional variations (linear and area changes), and reporting of results. Specific requirements for flatness, gaps between elements and height differences between elements are included but are applicable only to laminated floor coverings. The standard is a test method and does not itself set performance acceptance limits.

Key topics and requirements

• Definition of sample types and geometry for laminate and textile floor coverings.
• Specified humid and dry conditioning cycles and environmental parameters for reproducible testing.
• Procedures for measuring dimensional change (length, width and area) and calculation of percentage change.
• Additional checks for laminated products: flatness, openings/gaps between elements and height differences at joints.
• Requirements for reporting test conditions, measurement equipment, and results to ensure comparability.
• Clarification that the standard provides a method (not pass/fail criteria); acceptance criteria are determined by contract, national/regional regulations or purchaser requirements.

Typical use and users

Used by manufacturers of laminate and textile floor coverings for product development and quality control, independent test laboratories performing conformity or comparative testing, specifiers and procurement teams evaluating product suitability, and certification/approval bodies that need a standardized method to document dimensional behaviour under climatic exposure.

Related standards

Standards commonly referenced alongside ISO 24339 include other floor-covering test and classification standards (for example ISO 24340 for resilient floor coverings — thickness determination, and ISO 10874 for classification of resilient, textile and laminate floor coverings). National and regional product standards and installation or performance standards may also be relevant when interpreting results or setting acceptance criteria.

FAQ

Q: What is this standard?

A: ISO 24339:2006 is an international test method that specifies how to determine dimensional variations of laminate and textile floor coverings after exposure to defined humid and dry climate conditions.

Q: What does it cover?

A: It covers sample preparation, defined conditioning cycles (humid and dry), measurement procedures for linear and area dimensional changes, and additional checks for laminate flatness and joint behaviour. It defines how to report results but does not set accept/reject performance limits.

Q: Who typically uses it?

A: Manufacturers, product development and quality teams, independent testing laboratories, specifiers, procurement officers and certification bodies involved with floor-covering performance evaluation.

Q: Is it current or superseded?

A: The document was published in May 2006 (Edition 1). As of early 2026 the standard is published but has been subject to committee activity toward revision; users should check with their national standards body or ISO to confirm whether a revised edition or replacement has been issued before relying on it for current regulatory or procurement requirements.

Q: Is it part of a series?

A: It sits within the family of ISO standards for floor coverings (ICS 97.150) and is commonly used alongside other ISO standards addressing classification, thickness measurement and product-specific test methods for floor coverings.

Q: What are the key keywords?

A: Laminate, textile, floor coverings, dimensional variation, dimensional stability, humid/dry conditioning, flatness, joint gaps, ISO 24339.
