Overview

The EN 827:2005 standard, developed by the European Committee for Standardization (CEN), defines a precise methodology for determining the conventional solids content and, where feasible, the constant mass solids content in adhesives. This standard is essential for manufacturers, quality control laboratories, and researchers working with dispersion, emulsion, and solvent-based adhesives, ensuring accurate evaluation and consistent quality. EN 827:2005 supersedes the earlier EN 827:1994, providing updated procedural clarity and enhanced testing reliability.

Key Topics

• Scope: The standard applies specifically to dispersion, emulsion, and solvent-based adhesives. It covers test methods to quantify the solids content in these materials by controlled drying and weighing processes.
• Test Methods:
  • Conventional solids content is measured by drying a specified amount of adhesive at a defined temperature for a fixed time.
  • Constant mass solids content involves continued drying until weight loss stabilizes, indicating complete evaporation of volatile components.
• Apparatus Requirements:
  • Ovens with natural or forced ventilation capable of maintaining temperatures within ±1 °C.
  • Analytical balances accurate to 0.1 mg.
  • Flat-bottomed thin metal containers with specified dimensions.
  • Desiccators with suitable desiccants for accurate cooling and conditioning.
• Safety Considerations: The procedure involves heating adhesives, which may release toxic, harmful, or flammable volatile components. Proper lab practices and equipment such as extraction fans are mandatory to ensure operator safety.
• Sampling and Preparation: Follow relevant standards EN ISO 15605 and EN 1067 for representative sampling and sample preparation, ensuring consistency and reliability.
• Drying Conditions: Drying times and temperatures vary based on adhesive type - including natural, synthetic, aqueous dispersion, and solvent-based adhesives - to prevent heat degradation or loss of active ingredients.
• Result Expression: Results are calculated as percentages by mass, with duplicate tests to ensure precision. Differences between duplicate results must remain within acceptable limits (1-2%), otherwise retesting is required.
• Test Report Requirements: Detailed documentation must specify the standard reference, adhesive type, test conditions, results, any procedural deviations, and test dates to ensure traceability and quality control.

Applications

EN 827:2005 is critically important for:

• Adhesive Manufacturers: To verify product composition, manufacturing consistency, and compliance with specifications.
• Quality Control Laboratories: Monitoring solids content to maintain adhesive performance and stability.
• Research and Development: Developing new adhesive formulations by understanding solids content's influence on properties.
• Regulatory Compliance: Ensuring products meet regulatory requirements related to volatile content and safety.
• End-Users: Including industries such as woodworking, automotive, packaging, and construction relying on adhesives with certified quality parameters for bonding performance.

Measuring solids content accurately impacts key adhesive properties such as viscosity, drying time, bonding strength, and environmental safety, making this standard indispensable for optimizing adhesive applications.

Related Standards

The EN 827:2005 method integrates with and references several other key standards for adhesive testing, including:

• EN 923 – Adhesives: Terms and Definitions - Provides essential terminology clarification.
• EN 1067 – Adhesives: Examination and Preparation of Samples for Testing - Sets foundational sample handling protocols.
• EN ISO 15605 – Adhesives: Sampling - Details procedures for obtaining representative adhesive samples.

Together, these standards create a comprehensive framework for adhesive characterization, supporting consistent, comparable, and reliable testing across the adhesives industry.
