BS EN 6139:2020

What is BS EN 6139 about?  

BS EN 6139 discusses standards for cap, protective, non-metallic fitting ends. 

BS EN 6139 specifies the dimensions, tolerances, and required characteristics of protective caps, non-metallic, for EN 6123 fitting ends to seal fluid ports during transportation and storage in order to prevent: 

• Contamination by moisture, fluids, chemicals, and particles 
• Spillage inside package or aircraft section 
• Port and pipe end damages  
• Port and pipe clogging due to plug ingestion 

Who is BS EN 6139 for? 

BS EN 6139 on a cap, protective, non-metallic, for EN 6123 fitting ends is applicable to: 

• Manufacturers of aerospace hydraulic systems, fluids, and components 
• Aerospace and defense industries 
• Testing agencies involved in the inspection of fluids and components of aircraft and hydraulic motors 
• Manufacturers of hydraulic motors 
• Design engineers for hydraulic motors 

Why should you use BS EN 6139?  

The guidelines provided in BS EN 6139 related to hydraulic systems help engineers and technical decision-makers to evaluate the feasibility, reliability, and testability of the design scheme more accurately. 

BS EN 6139 provides guidelines about the dimension and characteristics of protective caps for fitting ends to seal fluid ports for the prevention of spillage and pipe clogging. 

As a manufacturer, you would use BS EN 6139 to ensure that the components that you are manufacturing for aerospace applications adhere to the specification. 

By adopting BS EN 6139, you can demonstrate the reliability of their hydraulic motors and build trust in their use throughout the aerospace supply chain.
