Overview

SIST EN 2757:2011 is a European Standard developed by CEN that specifies test methods for determining the drying and ignition residues of primers used in aerospace structural adhesive systems. This standard defines general requirements for two key measurements: the drying residue (solid content) identified by Method A, and the residue after ignition (corrosion inhibitor content) identified by Method B. Both tests are critical to evaluating primer performance in aerospace applications, ensuring reliability and safety in adhesive bonding processes.

Primers play an essential role in aerospace structures by enhancing adhesion and providing corrosion protection. Accurate measurement of drying and ignition residues guarantees that primers meet stringent quality criteria necessary for aerospace industry compliance.

Key Topics

• Method A: Drying Residue Determination

  • Measures the solid content of the primer by weighing a sample before and after a controlled drying process.
  • Reflects the proportion of non-volatile components such as polymers and corrosion inhibitors.
  • Drying temperature is controlled and sample weight is monitored until a constant mass is achieved.

• Method B: Residue After Ignition

  • Measures the corrosion inhibitor content by igniting the drying residue and weighing the remaining ash.
  • Evaluates the proportion of corrosion inhibitors to ensure primer effectiveness.

• Test Equipment and Materials

  • Heat-resistant crucibles and precision balances (accuracy to 1 mg).
  • Ovens capable of maintaining specific temperature ranges (200 ± 5 °C for drying; 595 ± 15 °C for ignition).
  • Desiccators with drying agents such as silica gel.

• Sample Preparation

  • Primers should be stored below ambient temperature and brought to test temperature sealed in original containers.
  • Samples range from 5 to 10 grams, thoroughly mixed before testing to ensure homogeneity.

• Expression of Results

  • Drying residue and ignition residue are calculated via weight differences and expressed as percentages.
  • Results are reported individually and as mean values, along with full test traceability.

Applications

SIST EN 2757:2011 is designed primarily for the aerospace industry, where structural adhesives and primers demand rigorous testing to comply with high safety and performance standards. Key applications include:

• Aerospace Manufacturing and Maintenance

  • Ensuring primers meet specifications for solid content and corrosion inhibitor levels critical for aircraft structural integrity.
  • Quality control during adhesive bonding processes for airframe assembly and repair.

• Material Certification

  • Validation of primer batches before release for use in aerospace production.
  • Support for compliance with aerospace material technical specifications and regulatory requirements.

• Research and Development

  • Development of new aerospace primer formulations with optimized drying and corrosion protection properties.
  • Comparative analysis of primer performance under standard test conditions.

Related Standards

For a comprehensive understanding and application of SIST EN 2757:2011, it is important to consider related aerospace adhesive and coating standards such as:

• EN 2642 - Aerospace series: Structural adhesive systems - Adhesive film - Technical specification.
• Other ASD-STAN Aerospace Standards covering adhesives, primers, and coatings to support structural bonding and corrosion protection.
• National aerospace certification standards enforcing material testing and traceability.

Using SIST EN 2757:2011 in combination with these standards ensures compatibility across testing protocols and materials evaluation in aerospace manufacturing environments.
