ISO 11485-1:2011

Overview

ISO 11485-1:2011 - Glass in Building - Curved Glass - Part 1: Terminology and Definitions is an international standard published by the International Organization for Standardization (ISO). This document defines the essential terminology related to curved glass products as used in general building construction, furniture, display, and other non-automotive applications. By providing a unified vocabulary, this standard supports clear communication and consistent understanding among manufacturers, designers, specifiers, and end users of curved glass components.

ISO 11485-1:2011 is the first part in a multi-part series addressing various aspects of curved glass used in architectural and design contexts.

Key Topics

The standard covers the following key areas:

• Definitions of Curved Glass Types: Includes basic forms such as curved annealed glass, curved tempered glass, curved laminated glass, and specialized types including patterned, wired, insulating, and heat-soaked tempered glass.
• Dimensional Terminology:
  • Arc, chord, girth, and rise
  • Inner and outer radii
  • Thickness and length
  • Concave and convex surfaces
• Geometric and Manufacturing Terms:
  • Plan, drawing, template, lay out, model, and curvature profile
  • Shape accuracy, cross-curve deviation, edge straightness deviation, twist deviation
• Quality-Related Terms:
  • Optical distortion, displacement, cold crack, pock marks, ring marks, tong marks, and gauge use

Clearly defined terms help stakeholders specify requirements more accurately and interpret drawings, plans, and performance metrics effectively.

Applications

ISO 11485-1:2011 is widely applicable across several sectors that utilize curved glass, including:

• Building Construction: Used in facades, skylights, atriums, canopies, staircases, and balustrades where curved glass enhances aesthetics and functionality.
• Furniture and Interior Design: For decorative panels, custom tables, partitions, and display cases.
• Retail and Display Installations: In showcases, shelving, or branding elements requiring specific glass contouring.
• Specialty Non-Automotive Uses: Such as marine, rail, and public infrastructure projects where technically accurate curved glass specifications are needed.

The terminology outlined in this standard enables clear technical communication for design, manufacture, and procurement, reducing misinterpretation and ensuring quality outcomes.

Related Standards

Professionals referencing ISO 11485-1:2011 should also consider these related standards for comprehensive project requirements:

• ISO 11485-2 - Curved glass: Quality requirements
• ISO 12543 (all parts) - Laminated glass and laminated safety glass
• ASTM C1464-06 - Standard Specification for Bent Glass

These complementary standards address additional aspects such as material performance, safety, and manufacturing tolerances, supporting the effective use of curved glass in buildings and other applications.
