BS ISO 4386-2:2019

What is ISO 4386-2-Tensile test method for metallic multilayer plain bearings about?   

ISO 4386 is an International Standard that discusses plain bearings.  

ISO 4386-2 is the second part of the multi-series that specifies a tensile test method for the determination of the bond strength between the bearing metal and the backing. 

The test can be applied to multilayer plain bearings with bearing metals based on lead, tin, copper or aluminum. For tested layer thicknesses ≥ 2 mm, a raw lining thickness of a minimum additional 1 mm is necessary. The backings are from steel, cast steel or copper alloys.  

Note: The bond strength test does not apply to bearings with cast iron backing. 

Who is ISO 4386-2- Tensile test method for metallic multilayer plain bearings for?  

ISO 4386-2 on plain bearings is applicable to: 

• Manufacturers of metallic multilayer plain bearings 
• Mechanical engineers  
• Product design engineers 
• Personnel involved in destructive testing 

Why should you use ISO 4386-2- Tensile test method for metallic multilayer plain bearings?  

ISO 4386-2 specifies a tensile test method for the determination of the bond strength between the bearing metal and the backing. The test can be used for comparative investigations into the influence on the bond strength of various processes and types of material.  

Given test is suitable for production control and for process qualification of bearing production. ISO 4386-2 gives a test method for guidance to avoid negative influence due to tolerances. 

Overall, you can minimize the risk of product failure and enhance bearing service-life by complying with ISO 4386-2. 

What’s changed since the last update?  

ISO 4386-2:2019 supersedes BS ISO 4386-2:2012, which is withdrawn. BS ISO 4386-2:2019 has been editorially revised. The change includes: 

• Adjustment to the ISO Directives, including the implementation of Clause 3 Terms and definitions
