JOMESA Filter Analysis: Particle Standards


Particle Standards:
In 2004 JOMESA was the first company to offer a particle standard to control measurement of filters with 47mm diameter.


Particle standard for particle sizes > 50µm

The JOMESA HFD particle standard:

Background with different brightness simulate staining effects on real filters.

This standard – unchanged since 2004 – is usually delivered with a calibration certificate, ensuring the trace-ability to national standards.

This standard is designed to check particle sizes 50µm up.


Particle standard for particle sizes > 5µm

To control and measure also small particle sizes, a further standard (called system standard) is used.

This standard is designed to check particle sizes from 5µm to 200µm.




Particle standard for particle sizes > 2µm
(DIN 51455, Draft)

The emerging standard for determination of cleanliness of oils (DIN 51455) requires a particle standard to ensure the capability of the measuring equipment. The J455 Standard is made for this.

This standard is designed for particle sizes from 2µm to 200µm.


All these standards can be delivered with a calibration certificate, ensuring the trace-ability to national standards.
