ISO 9383 specifies methods for the inspection and testing of fibre-reinforced cement sheets and fittings with short corrugated or asymmetrical sections used in roofing applications. The standard defines requirements for mechanical performance, durability, and dimensional accuracy, ensuring that roofing products meet consistent quality and structural reliability.

The test methods evaluate bending strength, impact resistance, and resistance to environmental conditions such as moisture, temperature changes, and weathering. These tests help to select roofing sheets and fittings that provide long-lasting, safe, and durable performance.
