Overview
ISO 5019-2:1984 - Refractory bricks - Dimensions - Part 2: Arch bricks specifies standardized dimensions for arch (vault) refractory bricks. Published by ISO/TC 33 (Refractory materials) in 1984, this part of ISO 5019 defines two series of arch bricks with constant average thickness (notably 64 mm and 76 mm series) and one series with a constant cold-face dimension. The document replaces the earlier recommendation ISO/R 1145-1969 and includes a tabulated set of brick formats (dimensions in millimetres) commonly used in industrial furnaces and kilns.
Key topics and technical requirements
- Dimension series: Two alternative systems are defined - series with average thickness constant (series 64 mm and 76 mm) and a system based on constant cold-face dimension. The 76 mm series is recommended for broad adoption.
- Tabulated formats: The standard provides a table of specific arch-brick dimensions (examples include common formats such as 230 × 114 × ... mm), covering various brick types and face configurations used for vault construction.
- Tolerances: Dimensional tolerances for the listed arch bricks are not universally fixed in this part; they must be agreed between buyer and supplier. Tolerances applying to rectangular bricks are specified in ISO 5019-1 and referenced where applicable.
- Compatibility note: ISO 5019-2 recognizes that some North American arch-brick formats (constant cold-face types) are very close to the tabulated dimensions.
Applications
- Standardizing arch brick dimensions for lining furnaces, kilns, boilers and other high-temperature installations.
- Facilitating modular refractory lining design, interchangeability and repeatable construction of vaults and arches.
- Simplifying procurement and inventory management by specifying commonly used brick formats.
- Supporting quality control and acceptance criteria for manufactured arch bricks.
Who uses this standard
- Refractory brick manufacturers and suppliers
- Furnace/kiln designers and refractory engineers
- Procurement and quality assurance teams in metallurgical, cement, glass and petrochemical industries
- Contractors and installation teams responsible for lining high-temperature equipment
