Glass in building - Glass blocks and glass pavers - Part 1: Definitions and description

This standard specifies regulations for the methods of manufacture and quality control referring to factory made glass blocks and glass pavers. Glass Blocks are used for the construction of building parts like non-bearing walls They have to be used in such a way that they only support their own weight in parallel with the visible surfaces and horizontal load, generated by wind and by impact loads perpendicular to the visible surfaces.

Glas in Bauwesen - Glassteine und Betongläser - Teil 1: Begriffe und Beschreibung

Diese Norm legt Anforderungen für die Herstellungsverfahren und die Prüfung der Beschaffenheit werksgefertigter Glassteine und Betongläser fest. Glassteine werden für die Herstellung nichttragendeer wandartiger Bauteile verwendet. Sie sind derart einzubauen, dass nur Eigengewicht parallel (siehe Bild 5) und Horizontallast aus Wind sowie Stossbeanspruchung senkrecht zu den Sichtflächen aufzunehmen sind.

Overview

EN 1051-1:2003 - Glass in building: Glass blocks and glass pavers - Part 1: Definitions and description is a CEN (European) standard that defines terminology, manufacturing and quality-control requirements for factory-made glass blocks (vertical, non-load-bearing wall elements) and glass pavers (horizontal glass units used in floors or in reinforced concrete panels). The standard sets material, dimensional, optical and compressive‑strength criteria, and describes the test methods and acceptance rules (normative annexes).

Key topics and technical requirements

• Scope and definitions: Clear definitions for glass blocks, glass pavers and types of visual faults (spot faults, opaque inclusions, linear/extended faults).
• Material: Products shall be manufactured from soda‑lime silicate glass in accordance with EN 572‑1. Edge coatings (if used) must be compatible and bonded to the glass.
• Forms and shapes: Typical forms include square, rectangular and circular units; examples and common formats are shown in Annex C.
• Dimensional tolerances:
  • Three tolerance classes (I, II, III): ±1.0 mm, ±1.5 mm and ±2.0 mm respectively.
  • Squareness: 90° ± 2°.
  • Surface bulges ≤ 2.0 mm; depressions ≤ 1.0 mm.
  • Non‑alignment allowances for pressed/fused edges (per 100 mm limits).
• Mass:
  • Nominal mass declared; measured mass tolerance ±10%.
  • Mass measured twice to 10 g accuracy and averaged.
• Compressive strength and breakage tests:
  • Test equipment to EN ISO 7500‑1 (class 2); loading rate 0.2–0.4 MN/m²·s.
  • Glass blocks: specified compressive strength requirements (see Annex A) - test uses a 10 mm ±2 mm levelling mortar layer (prepared per EN 196‑1 using Portland cement EN 197‑1) and 7 d curing before test. Average and minimum single values are defined.
  • Glass pavers: compressive strength classification and test method described in Annex B (stamp, rubber plates, base plate arrangement).
• Optical/visual acceptance:
  • Inspection under diffuse daylight, specimen lit from underneath and viewed at ~3 m perpendicular to visible face.
  • Visual faults are acceptable only if not visible under these conditions.

Applications and who uses this standard

• Practical uses: Specification, production control and acceptance of glass blocks used in non‑bearing walls, and glass pavers used in horizontal panels (including trafficked panels).
• Primary users:
  • Manufacturers and quality managers of glass blocks/pavers
  • Architects and façade/flooring specifiers
  • Building product testing labs and compliance officers
  • Construction contractors and façade installers
  • Standards bodies and certification organizations

Related standards

• EN 572‑1 (soda‑lime silicate glass properties)
• EN ISO 7500‑1 (verification of testing machines)
• EN 196‑1 and EN 197‑1 (mortars and cement for levelling layers)
• ISO 48 (rubber hardness for test pads)

Keywords: EN 1051-1:2003, glass blocks, glass pavers, glass in building, dimensional tolerances, compressive strength, soda lime silicate glass, CEN standard, quality control, optical requirements.
