ISO 16293-4:2016 specifies dimensional and minimum quality requirements (in respect of visual, pattern and wire faults) for wired patterned glass, as defined in ISO 16293‑1, for use in building. ISO 16293-4:2016 applies only to wired patterned glass supplied in rectangular panes, in stock sizes and in final cut sizes.

Overview

ISO 16293-4:2016 - "Glass in building - Basic soda lime silicate glass products - Part 4: Wired patterned glass" specifies dimensional and minimum quality requirements for wired patterned soda‑lime silicate glass used in buildings. The standard applies to wired patterned glass supplied as rectangular panes in stock sizes and final cut sizes. It defines how to measure thickness, length/width and squareness, the required characteristics of the embedded wire mesh, and visual acceptance criteria for pattern, wire and edge faults.

Key topics and technical requirements

Scope and definitions: Applies only to wired patterned glass as defined in ISO 16293‑1, supplied in rectangular panes (stock or final cut sizes).

Thickness measurement: Actual thickness is the average of four measurements taken near the centre of each side using a plate gauge (diameter 50 mm ± 5 mm), measured to 0.01 mm and rounded to 0.1 mm for tolerance checks.

Thickness tolerances: Numeric tolerances are specified by nominal thickness (examples in the standard: 6 / 6.8 mm ±0.6 mm; 7 mm ±0.7 mm; 8 mm ±0.8 mm; 9 mm ±0.9 mm; 10 mm ±0.9 mm).

Length / width / squareness: Tolerances for nominal dimensions and limits on diagonal difference (squareness) are provided for stock and final cut panes in different size ranges.

Wire mesh specification: Acceptable meshes include square meshes (~12.5 mm or 25.0 mm) and diamond mesh (~19 mm); mesh wires welded at intersections with wire diameter ≥ 0.42 mm.

Quality and visual acceptance:

Fault categories: spot faults, linear/extended faults, pattern faults (out of square, waviness, bow) and wire faults (out of square, waviness, bow, penetrations, breaks).
Observation method: Pane placed vertically 3 m in front of a matt grey screen; observer 1.5 m from the glass, viewing normal to the surface under diffuse daylight conditions.
Acceptance levels: Different limits for stock vs final cut sizes (e.g., some spot faults permitted within size limits; linear faults allowed in stock sizes at a defined average but no linear/extended faults are permitted in final cut panes).
Pattern and wire deviation limits: pattern out‑of‑square ≤ 12 mm/m; waviness and bow ≤ 12 mm; wire deviations ≤ 15 mm/m (or 15 mm for waviness/bow). No wire penetration of the surface is acceptable; wire breaks are acceptable only if not visually disturbing.

Edge defects for final cut sizes: Limits for entrant/emergent faults and bevels are given relative to glass thickness (e.g., entrant/emergent depths
