ISO 9933 specifies methods for the inspection and testing of fibre-reinforced cement sheets and fittings with long corrugated or asymmetrical sections, intended for roofing and cladding applications. 

The test methods assess bending strength, impact resistance, and performance under environmental conditions such as moisture, temperature variations, and weathering. These tests help to select sheets and fittings that deliver safe, durable, and long-lasting performance in roofing and cladding systems.
