Overview
ISO 10904:2011 - Fibre‑cement corrugated sheets and fittings for roofing and cladding specifies technical requirements and test/inspection methods for straight short and long fibre‑cement profiled (corrugated) sheets and associated fibre‑cement fittings used as weather‑exposed surfaces on roofs and internal/external walls. The standard covers composition, manufacture, dimensional tolerances, physical performance and conformity assessment (type tests, acceptance tests and quality control). It excludes asbestos‑reinforced products and does not evaluate coating performance in isolation (coating properties are covered in other standards).
Key topics and technical requirements
- Scope and product definitions: classification of short (≤ 0.9 m) and long (> 0.9 m) sheets, profile dimensions (pitch, height), fittings and terminology.
- Material and composition: cement or calcium‑silicate matrices reinforced with cellulose, synthetic or glass fibres; permitted forms (discrete fibres, strands, nets).
- Manufacture & appearance: permitted forming and curing methods; requirements for as‑delivered condition and finish.
- Dimensional requirements: nominal dimensions, tolerances and geometrical testing procedures (see normative annexes).
- Mechanical performance: breaking load, bending moment at rupture and bending modulus measured by standardized bending tests; definitions and test methods are provided (annexes include test procedures).
- Physical properties and durability tests: apparent density, water permeability, freeze–thaw, heat‑rain, warm water and soak‑dry performance - each with normative test methods.
- Impact resistance & fire behaviour: references and requirements for impact testing and fire classification as applicable.
- Conformity & sampling: type testing, production quality control systems, consignment inspection and statistical sampling plans.
- Exclusions & coating note: coatings are not assessed in isolation; specific coating performance should reference separate international or national standards.
Practical applications
- Ensures consistent quality and safety for roofing and cladding made from fibre‑cement corrugated sheets.
- Guides manufacturers on production controls, test regimes and product labeling.
- Informs architects, specifiers and contractors on expected material properties for design, procurement and installation decisions.
- Provides test laboratories and certification bodies with standardized test methods and sampling procedures for performance verification.
Who should use ISO 10904:2011
- Fibre‑cement product manufacturers and R&D teams
- Quality control and testing laboratories
- Building product certifiers and conformity assessors
- Architects, engineers, contractors and procurement officers specifying roofing and cladding materials
