Door leaves - General and local flatness - Measurement method

ISO 6442:2005 can be applied to all rectangular door leaves. ISO 6442:2005 specifies the method to be used to measure the deviations in general and local flatness of door leaves. In ISO 6442:2005, the concept of local flatness deviation is limited to defects considered to be prejudicial to the appearance of the door leaf.

Vantaux de portes — Planéités générale et locale — Méthode de mesure

L'ISO 6442:2005 peut s'appliquer à tous les vantaux de portes rectangulaires. L'ISO 6442:2005 définit la méthode à utiliser pour mesurer les écarts de planéité générale et locale des vantaux. Dans l'ISO 6442:2005 le concept d'écart de planéité locale est limité aux défauts considérés comme préjudiciables à l'aspect du vantail.

Overview

ISO 6442:2005 is an international standard that specifies the measurement method for assessing the general and local flatness of rectangular door leaves. This standard is essential for manufacturers, quality inspectors, and engineers involved in door production and quality assurance processes. The key purpose of ISO 6442:2005 is to ensure door leaves meet flatness requirements that sustain their structural integrity and aesthetic appearance.

The standard defines precise procedures to measure deviations from flatness, focusing both on global deformations such as warping or twisting, and on localized flatness defects that may adversely affect the door's visual appeal. By following ISO 6442:2005, users can reliably identify flatness defects to maintain product quality and customer satisfaction.

Key Topics

  • Scope: Applicable to all rectangular door leaves, including those used in residential, commercial, and industrial environments. It covers both general and localized flatness deviations.

  • Measurement Equipment:

    • A rigid, vertically mounted frame with four reference points matching the door leaf’s dimensions.
    • Straight reference bars for measuring along the height or edges.
    • Precision analog or digital comparators with a resolution of 0.01 mm.
    • 200 mm reference bars equipped with comparators specifically for local flatness measurement.
  • Measurement Procedures:

    • General Flatness (Torsion): Position the door leaf against a planar frame and measure deviations at each corner to detect twisting.
    • General Flatness (Bending): Use a straight reference bar along each edge of the door leaf to determine warping or arching.
    • Local Flatness: Detect any surface defects that impair appearance using a 200 mm long reference bar and a comparator, measuring unconstrained door leaves.
  • Environmental Conditions: Measurements should be conducted in controlled conditions (15 °C to 30 °C, 25% to 75% relative humidity) to avoid environmental influence on materials.

  • Reporting: Test reports must include all relevant details such as door identification, material, dimensions, testing environment, measurement results, test date, and laboratory information.

Applications

ISO 6442:2005 is widely utilized by:

  • Manufacturers: To implement quality control during production, ensuring door leaves comply with flatness requirements before shipment.
  • Inspection Bodies: For certification and conformity assessments of door products.
  • Architects and Builders: To specify acceptance criteria for door leaf flatness in construction projects.
  • Material Suppliers: To evaluate raw materials or semi-finished door leaves for flatness compliance.
  • Maintenance Professionals: To diagnose flatness-related issues affecting door performance and aesthetics.

This standard supports enhanced product durability, improved visual quality, and compliance with building codes or project specifications, reducing returns and customer complaints.

Related Standards

For comprehensive door quality management and performance evaluation, ISO 6442:2005 is often used in conjunction with the following standards:

  • ISO 10077 - Thermal performance of windows and doors.
  • ISO 20471 - Specifies door hardware and accessories, which may affect flatness indirectly.
  • ISO 9227 - Corrosion tests on metallic door components.
  • EN 952 - The European equivalent of ISO 6442, also providing measurement methods for door flatness.

Utilizing ISO 6442:2005 alongside these standards ensures complete compliance and performance optimization of door systems in diverse applications.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6442 was prepared by Technical Committee CEN/TC 33, Doors, windows, shutters, building hardware
and curtain walling (as EN 952:1999) and was adopted, under a special “fast-track procedure”, by Technical
Committee ISO/TC 162, Doors and windows in parallel with its approval by the ISO member bodies.
This second edition cancels and replaces the first edition (ISO 6442:1981) which has been technically revised.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
