JOMESA Particle Standards for ISO 16232, ISO 4406, DIN 51455

Accredited calibration lab, Certified particle standards

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.
In 2019 JOMESA was accredited calibration laboratory according DIN EN ISO/IEC 17025 for particle standards


Particle standard for particle sizes > 50µm

The JOMESA HFD particle standard:

Background with different brightness simulate inhomogeneous background on real filters.

This standard – unchanged since 2004 – is usually delivered with a DAkkS 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.
It cantains also scales for microscope calibration.

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


For this standard a DAkkS calibration certificate is available.





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

The standard for determination of cleanliness of oils (DIN 51455) requires a particle standard to ensure the capability of the measuring equipment.

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

For this standard a DAkkS calibration certificate is available.



JOMESA is an accredited calibraton lab according to DIN EN ISO/IEC 17025 and authorized to issue DAkkS calibration certificates.
