ISO 9125 specifies methods for the inspection and testing of fibre-cement slates and fittings used in roofing applications. The standard defines requirements for dimensional accuracy, mechanical strength, durability, and performance under load.

The test methods cover mechanical and physical properties, including bending strength, impact resistance, and resistance to environmental conditions such as moisture and temperature variations. These tests help to select slates and fittings that provide reliable and durable performance in construction projects.
