Overview

EN 12467:2012+A2:2018 - issued by CEN - is the European standard for fibre‑cement flat sheets (including siding shingles and planks). It defines the product specification and test methods for sheets intended primarily for internal and external wall and ceiling finishes. The standard sets technical requirements, inspection and test methods, acceptance conditions, factory production control (FPC) and assessment rules (AVCP). It applies to sheets reinforced with different fibre types (see Clause 5.1.1) and explicitly does not cover sheets designed for fire‑protection applications or design/installation requirements (e.g., wind uplift or rain‑proofing).

Key Topics

• Scope and classification: Product categories (A, B, C, D), groups of sizes and permitted uses.
• Composition and appearance: Requirements for materials, surface finish and visible quality.
• Dimensions and tolerances: Nominal length, width, thickness, shape tolerances and measurement procedures.
• Physical performance:
  • Bending strength (MOR) and modulus of elasticity (MOE)
  • Apparent density
  • Water impermeability and water vapour permeability (category‑dependent)
  • Moisture movement characteristics (Annex C)
• Durability/climatic tests: Freeze–thaw, heat‑rain, warm water and soak‑dry cycles to verify long‑term performance.
• Reaction to fire and release of dangerous substances requirements (not for fire‑protection use).
• Assessment & control: Type testing, factory production control (FPC), consignment inspection, statistical methods for correlating wet/dry test results (Annex B).
• Test methods: Detailed procedures for specimen preparation, apparatus, test execution and result interpretation (Clause 7).
• Marking, labelling and packaging requirements and the relationship to EU Construction Products Regulation (Annex ZA).

Applications

EN 12467 is used to ensure consistent quality and performance of fibre‑cement flat sheets in building products such as:

• External wall cladding and facades
• Internal wall and ceiling finishes
• Siding shingles and planks
• As rigid underlays where compatible with specific application standards

Who uses it:

• Manufacturers and product developers for compliance and CE marking
• Test laboratories and quality control personnel
• Architects, specifiers and contractors selecting façade and cladding materials
• Certification bodies and regulatory authorities

Related standards

• EU Regulation No. 305/2011 (Construction Products Regulation) - referenced via Annex ZA for AVCP alignment
• Other application or installation standards (design, wind uplift, waterproofing) - EN 12467 does not replace these and should be used together with relevant design/installation standards.

This standard is essential when specifying, testing or certifying fibre‑cement sheets to ensure durability, dimensional conformity and safe performance in building envelope and interior applications.

When tested in accordance with the method specified in 7.3.1, the density shall be not less than this value. 5.4.3 Moisture movement The manufacturer's literature shall state the percentage value of linear sheet moisture movement measured when the sheet is exposed to a relative humidity change from 30 % to 90 %. The stated value shall be determined in accordance with 7.3.7 using the test method given in Annex C. 5.4.4 Mechanical characteristics – Bending strength (MOR) – Modulus of elasticity (MOE) When tested as specified in 7.3.2, the minimum modulus of rupture of the sheets, expressed in megapascals, shall be as specified in Table 6. The MOR shall be the average of the values obtained from testing the samples in both directions. NOTE For non-homogeneous e.g. coated sheets, Table 6 refers to the apparent MOR. Category A and B sheet strengths are specified in the wet condition (see Table 10). Category C and D sheet strengths are specified in the ambient condition (see Table 10). The manufacturer shall specify the characteristic value for mechanical strength. Characteristic values of bending strength are based on statistical data on results of tests in ambient conditions. The statistical interpretation of test results is based on the procedure prescribed in EN 1990:2002, Eurocode — Basis of structural design, Table D.1, Vx, unknown). If a correlation has been established (see Annex B) between the MOR from production control and the MOR from products as delivered, the k-value of V x,known can be used. The minimum modulus of rupture of the sheets in the weaker direction shall be not less than 70 % of the specified value in Table 6 for the average of the two directions. This requirement does not apply to textured sheets. The modulus of elasticity of the sheets, expressed in Giga- or Megapascals, shall be specified on test results of tests in ambient conditions. The MOE shall be the average of the values obtained from testing the sampling in both directions with indication of the standard deviation. It is up to the manufacturer to determine the MOE for information purposes, i.e. with type testing. Table 6 — Minimum modulus of rupture (MOR) min. MOR in the wet condition MPa min.
