What is BS EN 14865-1 - Testing method for determining the lubrication ability of Axlebox lubricating greases about?
BS EN 14865-1 specifies a testing method and sets the acceptance criteria for determining of the lubrication ability of lubricating greases intended for the lubrication of axle box bearings. The lubricating ability, primarily related to the capability of lubricating greases to protect against wear, is determined in a roller-bearing lubricant test rig. Wear of the rolling bearing rollers, the frictional behavior, and temperature during the test are used to discriminate between lubricating greases.
Note1: The testing method is referred to in EN 12081.
The method described is carried out in order to test axle box greases for ordinary-speed vehicles, with speeds up to 200 km/h, and for greases intended for high-speed vehicles, with speeds up to 300 km/h. The method is a discriminating process, and those greases that pass will be subject to more extensive performance tests.
For purpose of quality assurance and quality control, this test method is also used for batch testing of greases intended for use in axle boxes.
Note 2: For light rail and tramway applications, other standards or documents agreed between the customer and the supplier may be applied.
Who is BS EN 14865-1 - Testing method for determining the lubrication ability of Axlebox lubricating greases for?
BS EN 14865-1 on testing method for determining the lubrication ability of Axlebox lubricating greases is useful for:
- Testing laboratories
- Railway industry
- Producers of axlebox lubricating greases
Why should you use BS EN 14865-1 - Testing method for determining the lubrication ability of Axlebox lubricating greases?
BS EN 14865-1 standardizes a test method and acceptance criteria for the demand in EN 12081 for testing the ability of greases to lubricate axlebox bearings. It addresses the issue of the lubricating ability of lubricating greases operating under severe conditions.
All lubricants have three main functions: to form a lubricating film that separates rolling elements and raceways, to protect the bearing from corrosion, and give good longevity. For lubricating greases in axle boxes, there is also the demand that the product must keep the lubricating ability, sometimes without relubrication, during very long periods of time under arduous operating and environmental conditions.
The testing procedure in BS EN 14865-1 is severe and is used to discriminate between lubricating greases of different lubricating abilities.
