A standard for high-performance powder coatings used as a durable finish on fence components.
BS EN 12206:2021 is the current European standard for paints and varnishes, specifically defining the performance and test requirements for organic powder coating applied to aluminium and aluminium alloys used in architecture (e.g., windows, doors, facades, and curtain walling).
This standard is essential because it specifies procedures to assess and verify the performance characteristics of the coating, ensuring it provides the necessary quality, durability, and aesthetic finish required for long-term exposure in external, architectural environments. It ensures the protective finish can withstand strict criteria for weathering, adhesion, and resistance to chemical and mechanical stress.
The scope of our accreditation ensures compliance in the following critical areas:
Substrate Pre-treatment: Verification of the chemical cleaning and conversion process (e.g., chromating or non-chromate) essential for achieving optimal coating adhesion and corrosion resistance.
Coating Characteristics: Assessment of the applied coating, including the dry film thickness (ensuring it meets minimum required microns), the degree of cure, and the visual appearance (colour, gloss, consistency).
Performance Testing: Rigorous validation that the finished product meets the standard’s defined thresholds for adhesion, resistance to deformation, and resistance to impact.
Durability and Weathering: Confirmation of compliance with tests for accelerated weathering and UV resistance, guaranteeing the coating maintains its structural and aesthetic properties against environmental exposure.
| Test Parameter | Standard Reference | Verification Procedure |
| Adhesion | EN ISO 2409 (Cross-cut test) | Ensures the coating does not detach from the substrate. |
| Resistance to Rapid Deformation | EN ISO 1519 (Conical mandrel test) | Checks for cracking when the coated material is bent. |
| Film Thickness | EN ISO 2360 (Eddy current method) | Confirms the dry film is within the required micron range. |
| Resistance to Mortar | Annex B of EN 12206:2021 | Verifies resistance to construction-related chemicals. |
| Accelerated Weathering | EN ISO 16474-3 (UV-A or UV-B exposure) | Simulates long-term environmental exposure to assess colour and gloss retention. |
Certification to BS EN 12206:2021 provides our clients with the highest level of assurance regarding the quality and longevity of our powder-coated aluminium products.
Guaranteed Durability: You receive a product with a tested and verified coating life, ensuring excellent long-term colour stability and protection against corrosion and degradation from environmental factors.
