BS EN 2491:2011

Overview

BS EN 2491:2011 specifies the requirements for molybdenum disulphide dry lubricants used in the aerospace sector. This standard outlines the various coating methods applicable to these lubricants, ensuring that they meet the rigorous demands of aircraft and space vehicle engineering. Molybdenum disulphide is renowned for its excellent lubricating properties, particularly in high-load and high-temperature environments, making it a critical component in aerospace applications.

Key Requirements

The standard provides detailed guidance on the following aspects:

• Coating Methods: Various techniques for applying molybdenum disulphide coatings are described, including spray, brush, and dip methods. Each method is evaluated based on its suitability for different aerospace components.
• Quality Control: The standard outlines the necessary quality control measures to ensure that the lubricants meet specified performance criteria. This includes testing for adhesion, thickness, and lubricating efficiency.
• Environmental Considerations: Compliance with environmental regulations is addressed, ensuring that the application of these lubricants does not adversely affect the environment.
• Performance Testing: The standard specifies the performance testing methods that must be employed to validate the effectiveness of the lubricants in operational conditions.

Implementation Benefits

Adhering to BS EN 2491:2011 offers several practical benefits for aerospace manufacturers and engineers:

• Enhanced Reliability: By following the specified coating methods and quality control measures, manufacturers can enhance the reliability of components, reducing the risk of failure during operation.
• Improved Performance: The use of molybdenum disulphide lubricants can significantly improve the performance of moving parts, particularly in extreme conditions, leading to longer service life and reduced maintenance costs.
• Regulatory Compliance: Compliance with this standard helps organisations meet regulatory requirements, thereby avoiding potential legal and financial penalties associated with non-compliance.
