Overview
ISO 22496:2021 is an international standard published by the International Organization for Standardization (ISO) that defines general terminology for windows and pedestrian doors. This standard establishes consistent vocabulary to support communication, design, manufacturing, and quality assurance processes across the doors and windows industry. The first edition of ISO 22496 replaced the older ISO 1804:1972, reflecting technical updates and expanded coverage relevant to both windows and pedestrian doors.
Key Topics
ISO 22496:2021 provides a comprehensive glossary covering terms and definitions related to the components, configurations, and functions of windows and pedestrian doors. Key topics include:
Window Terminology
- Window Components: Definitions for sash, frame, mullion, transom, glazing bead, glazing bar, sill, and rebate.
- Types of Windows: Fixed window, casement window, coupled window, double window, sliding window, ribbon window, fanlight, roof/skylight window, and pivot window.
- Operating Characteristics: Active sash or casement, passive sash, latched, locked, fastened, secured, and direction of rotation for hinged or pivoted windows.
- Glazing Specifications: Bonded glazing, direct glazing, and infill materials.
- Functional Features: Daylight opening sizes, interlocking stile, and door height window (French window or casement door).
Pedestrian Doors Vocabulary
- Door Components: Frame, head, jamb, stile, rail (top, bottom, mid), muntin, glazing bead, astragal, threshold, and overpanel.
- Door Types and Functions: Single and multi-leaf doors, active and passive leaf, double action door, flush door leaf, glazed door leaf, external and internal doorsets.
- Operational Terms: Fastened, latched, locked, closing face, clear opening height, direction of rotation, and secured.
- Special Features: Fanlight above doors, interlocking stiles for sliding doors, and door assemblies.
The standard includes informative annexes with illustrative figures to clarify component positions and opening functions.
Applications
ISO 22496:2021 is crucial for professionals in construction, architecture, manufacturing, and building maintenance. Practical applications include:
- Design and Specification: Architects and engineers use the standardized vocabulary to specify window and door requirements accurately in drawings and contracts.
- Manufacturing: Producers of windows and pedestrian doors apply the terms for consistent product descriptions, quality control, and compliance with regulatory requirements.
- Installation and Maintenance: Installation teams and maintenance personnel benefit from clear terminology to ensure correct fitting, operation, and repair according to industry standards.
- Regulatory and Compliance: Regulatory authorities adopt the standard terms to harmonize permitted product types and safety requirements in building codes.
- Education and Training: Technical education programs in building construction and architectural design incorporate ISO 22496 vocabulary to train future professionals.
Related Standards
ISO 22496 complements and interacts with a range of international standards focusing on building components and accessibility, such as:
- ISO 10077-1: Thermal performance of windows and doors
- ISO 12567: Thermal performance of windows and doors - Determination of solar factor
- ISO 140: Acoustics - Measurement of sound insulation in buildings
- ISO 21542: Accessibility and usability of the built environment
- EN 14351-1: Performance characteristics of windows and doors (European standard)
By aligning terminology with these standards, ISO 22496 supports an integrated approach to building envelope design and assessment.
