Product reliability b10d
Reliability of the pneumatic components used in safety systems b10 d values to use in application of EN ISO 13849-1 Reference: ISO 19973 - Pneumatic Fluid Power - Assessment of component reliability by testing
b10 d is the number of cycles until 10% of the components fail dangerously.
In pneumatic, mechanical and electromechanical technology, the life and reliability of components generally depends on wear linked to movements. Their life is also strongly affected by the working conditions, especially the following:
- Compressed air quality and conditions
- Lubricant compatibility with gaskets
- Environmental factors as such dust, gas and fluids.
It is vital for the component manufacturer's requirements to be complied with, otherwise the failure parameters are not valid. Product operating conditions are shown in Metal Work's General Catalogue.
Unless specified otherwise in the catalogue, compressed air must be class 3-4-3, in accordance with ISO 8573-1.
