EN 952:1999

Door leaves - General and local flatness - Measurement method

This standard can be applied to all rectangular door leaves. The standard specifies the method to be used to measure the deviations in general and local flatness of door leaves. In this standard the concept of local flatness deviation is limited to defects considered to be prejudicial to the appearance of the door leaf.

Türblätter - Allgemeine und lokale Ebenheit - Meßverfahren

Diese Europäische Norm kann bei allen rechtwinkligen Türblättern angewandt werden. Diese Norm legt das anzuwendende Meßverfahren zur Ermittlung der Abweichungen von der allgemeinen und der lokalen Ebenheit von Türblättern fest. In dieser Norm ist der Begriff der lokalen Ebenheitsabweichung auf Fehler begrenzt, die als nachteilig für das Aussehen des Türblattes betrachtet werden.

Vantaux de portes - Planeités générale et locale - Méthode de mesure

Cette norme européenne peut s'appliquer à tous les vantaux rectangulaires. Cette norme européenne définit la méthode à utiliser pour mesurer les écarts de planéité générale et locale des vantaux. Dans cette norme européenne le concept d'écart de planéité locale est limité aux défauts considérés comme préjudiciables à l'aspect du vantail.

Overview

EN 952:1999 is a European standard developed by CEN that defines the measurement methods for assessing the flatness of rectangular door leaves. This standard specifically addresses both general and local flatness deviations, with a focus on defects that could negatively impact the door leaf’s appearance. It serves as a vital guideline for manufacturers, quality inspectors, and industry professionals involved in door production and quality control.

The standard promotes a consistent approach to evaluating door flatness, ensuring product reliability and aesthetic quality. Its application enhances customer satisfaction by minimizing visual defects and improving overall door performance.

Key Topics

• Scope and Applicability: Applies to all rectangular door leaves regardless of material or construction type.
• General Flatness Measurement: Methods to assess the overall flatness of the entire door leaf surface.
• Local Flatness Measurement: Techniques for identifying localized flatness deviations that affect the door’s appearance.
• Assessment Criteria: Focus on deviations deemed prejudicial to the visual quality of the door leaf.
• Measurement Procedures: Standardized steps and tools to accurately measure flatness deviations.
• Quality Control Importance: Usage in production processes to maintain consistent product quality and compliance with design specifications.

Applications

• Door Manufacturing: Enables manufacturers to verify dimensional quality and surface flatness during and after production.
• Quality Inspection: Provides inspection teams with standardized methods for flatness assessment to ensure compliance with industry requirements.
• Product Certification: Assists in certification and compliance verification with European construction and building regulations.
• Material Selection and Design: Influences design decisions and material choices by highlighting flatness tolerances.
• Customer Assurance: Helps maintain high aesthetic standards to meet customer expectations for door appearance.
• Construction Projects: Used by contractors and architects to specify acceptable flatness in door installations.

Related Standards

• EN 14351-1 - Windows and Doors: Performance Characteristics - Offers broader performance criteria including mechanical properties and durability.
• EN 942 - Windows and Doors: Terminology - Defines terms related to door components and quality attributes.
• EN 12519 - Door and Window Components: Tolerances and Dimensions - Addresses dimensional tolerances which complement flatness requirements.
• ISO 13894 - Building elements: Methods for flatness measurement - Provides alternative measurement techniques applicable across different building materials.

Using EN 952:1999 ensures uniformity and reliability in the evaluation of door leaf flatness, supporting high-quality door production and installation in European and international markets.
