BS EN 12487:2007

Overview

BS EN 12487:2007 specifies the requirements for rinsed and non-rinsed chromate conversion coatings on aluminium and aluminium alloys. These coatings are essential for enhancing corrosion protection, improving adhesion for subsequent coatings, and providing a base for further surface treatments. This standard is crucial for manufacturers and processors of aluminium components who seek to ensure longevity and reliability in their products.

Key Requirements

• Coating Types: The standard covers both rinsed and non-rinsed chromate conversion coatings, each with distinct application processes and performance characteristics.
• Performance Criteria: Coatings must meet specific performance criteria regarding corrosion resistance, adhesion, and appearance.
• Testing Methods: The standard outlines various testing methods to assess the effectiveness of the coatings, including salt spray tests and adhesion tests.
• Environmental Considerations: Compliance with environmental regulations is a key aspect, particularly concerning the use of hexavalent chromium in coatings.

Implementation Benefits

Implementing BS EN 12487:2007 provides several advantages for manufacturers:

• Enhanced Corrosion Resistance: The application of chromate conversion coatings significantly improves the corrosion resistance of aluminium components, extending their service life.
• Improved Surface Properties: These coatings enhance surface properties, facilitating better adhesion for paints and other finishes.
• Quality Assurance: Adhering to this standard allows manufacturers to demonstrate compliance with industry best practices, thereby enhancing product quality and customer satisfaction.
• Market Competitiveness: Compliance with BS EN 12487:2007 can provide a competitive edge in the market, as it signifies a commitment to quality and reliability.

Compliance Value

Compliance with BS EN 12487:2007 is not only a matter of meeting regulatory requirements but also a strategic advantage:

• Regulatory Compliance: Ensuring that products meet the requirements of this standard helps manufacturers comply with relevant legislation regarding chemical use and environmental protection.
• Risk Mitigation: By following the guidelines set forth in this standard, manufacturers can reduce the risk of product failure due to corrosion, which can lead to costly recalls and reputational damage.
• Customer Confidence: Demonstrating compliance with recognised standards builds trust with customers and stakeholders, reinforcing the reliability of the products offered.

In conclusion, BS EN 12487:2007 serves as a vital framework for manufacturers in the aluminium sector, guiding them in the application of chromate conversion coatings. By adhering to this standard, companies can enhance product durability, ensure regulatory compliance, and maintain a competitive edge in the marketplace.
