This document specifies a method for the determination of the modulus of rupture of dense and insulating shaped refractory products at ambient temperature, under conditions of a constant rate of increase of stress. Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products. This document is also applicable to unshaped refractories (see ISO 1927-6) after preparation of test specimens according to ISO 1927-5.
Abstract
Overview
EN ISO 5014:2025 - Dense and insulating shaped refractory products - specifies a standardized laboratory method for determining the modulus of rupture (MOR) of shaped refractory products at ambient temperature. The test uses a controlled, constant rate of increase of stress in a three‑point bending configuration to measure the maximum bending stress a prismatic test piece can withstand. The standard applies to shaped refractories (standard bricks, special shapes and pre‑cast products) and can also be used for unshaped refractories after specimen preparation (ISO 1927‑5).
Key topics and technical requirements
- Test principle: Three‑point bending of a prismatic test piece until failure; MOR calculated from peak load assuming linear elastic bending.
- Scope of materials: Dense refractories (true porosity
