BS EN 1721:1999

Overview

BS EN 1721:1999 specifies the method for measuring the tack of pressure-sensitive adhesives used in various applications, including paper and board, packaging, and disposable sanitary products. This standard focuses on the determination of rolling ball tack, which is a critical property for assessing the performance of adhesives in practical applications.

Key Requirements

The standard outlines the procedure for measuring the tack of adhesives by employing a rolling ball method. The key requirements include:

• Test Apparatus: The test requires a specific apparatus that includes a steel ball and a smooth surface for adhesive application.
• Sample Preparation: Adhesive samples must be prepared according to specified conditions to ensure consistency and reliability in results.
• Measurement Procedure: The procedure involves rolling a ball down a defined slope and measuring the distance it travels before adhering to the adhesive surface.
• Reporting Results: Results must be reported in accordance with the standard's guidelines, ensuring clarity and comparability.

Implementation Benefits

Adopting BS EN 1721:1999 provides several benefits for manufacturers and compliance professionals:

• Quality Assurance: The standard helps in ensuring that adhesives meet performance criteria, which is vital for product reliability.
• Consistency: By following a defined testing procedure, manufacturers can achieve consistent results across different batches of adhesives.
• Market Competitiveness: Compliance with this standard can enhance product credibility and marketability, as it demonstrates adherence to recognised quality benchmarks.

Compliance Value

Compliance with BS EN 1721:1999 is essential for manufacturers in the rubber and plastics industries. It not only ensures that products meet safety and performance standards but also aligns with regulatory requirements. This compliance can lead to:

• Reduced Liability: Adhering to recognised standards can mitigate risks associated with product failures.
• Enhanced Customer Trust: Demonstrating compliance with established standards can build trust with customers and stakeholders.
• Facilitated Market Access: Many markets require compliance with international standards for product acceptance, making BS EN 1721:1999 a valuable asset for export-oriented businesses.

In conclusion, BS EN 1721:1999 serves as a vital tool for ensuring the quality and performance of pressure-sensitive adhesives. By implementing this standard, manufacturers can achieve significant compliance benefits, enhance product quality, and maintain competitiveness in the market.
