Overview

EN 15681-1:2016 - Glass in building: Basic alumino silicate glass products - Part 1 defines and classifies alumino silicate glass used in building applications. It specifies chemical composition ranges, general physical and mechanical properties, dimensional requirements and minimum quality criteria (optical and visual faults). The standard applies to glass supplied in stock sizes, supplied sizes or final cut sizes for end use, but does not apply to final cut sizes smaller than 100 mm in any dimension or with a surface area less than 0.05 m².

Key Topics

• Definitions and classification: clear definitions for alumino silicate float, drawn sheet and rolled glass and terms such as stock size, supplied size and final cut size.
• Chemical composition: sets ranges for major constituents (for example Si and Al percentages are specified) and allows certain alkali/earth/metal components within defined limits.
• Physical and mechanical characteristics: conventional values for density (≈2300–2600 kg/m³), Knoop hardness (≈400–700), Young’s modulus (≈70–90 GPa), Poisson’s ratio (≈0.20–0.25), thermal expansion, conductivity and refractive index (≈1.50–1.55). These values are guidance for general calculations where high accuracy is not required.
• Characteristic bending strength: specified as 45 MPa for alumino silicate float glass and 25 MPa for drawn sheet and rolled glass (for quasi‑static loads).
• Dimensional requirements: manufacturing dimensions, thickness tolerances, length/width/squareness and permitted deviations for stock/supplied/final sizes.
• Quality requirements: definitions and acceptance levels for optical faults (distortions seen through glass), visual faults (spot and linear/extended faults), and edge defects (entrant/emergent faults, bevels). Methods of observation and measurement are described.
• Stability and compliance: notes on long‑term stability of physical/chemical properties and complementary information related to REACH.

Applications

• Specification and procurement of alumino silicate glass for facades, windows, partitions and architectural glazing.
• Production control and quality assurance in glass manufacturing and processing.
• Input data for structural and thermal design where conventional material values are acceptable.
• Basis for acceptance/rejection criteria for delivered glass panes and inspection at glazing/assembly stages.

Who uses this standard?

• Glass manufacturers and suppliers
• Architects, façade and structural engineers
• Glazing contractors and installers
• Product certifiers, testing laboratories and regulatory bodies
• Specifiers preparing material schedules and procurement documents
