The new standard (IP 646 ) for particle counting in Marine Methanol Fuel

We’re pleased to share an important industry update - the release of IP 646, a new standard for measuring particle contamination in marine methanol fuels.

As methanol becomes an increasingly important marine fuel, a new specification, ISO 6583:2024 Methanol as a fuel for marine applications — General requirements and specifications, includes particle counting and states the preliminary method IP PM-FI in Annex D Fuel Cleanliness.This has now transitioned to a full test method, IP 646.

IP 646 provides a consistent and reliable way to determine the concentration of dispersed particles, helping ensure cleaner fuel systems and improved engine reliability.

 


AvCount3 for IP 646 particle counting

Seta’s AvCount3 Particle Counter is a compact, high-precision automatic particle counter that aligns with the requirements of IP 646. Designed for fuel, oil and fluid contamination analysis, AvCount3 measures particle size and distribution using light obscuration, as defined in IP 646.
 
 


• Measurement Range: From 2 µm to 100 µm, covering the IP 646 range of 4 µm(c) to 30 µm(c)
• Calibration Traceability: Fully compliant with ISO 11171
• Automated Operation: Touchscreen interface, programmable methods and built-in data reporting
• Versatile Compatibility: Suitable for fuels, biodiesel, hydraulic fluids and methanol samples
• Data Connectivity: Supports LIMS integration and automatic reporting 

With these features, the AvCount3 SA1100-0 provides laboratories and marine fuel suppliers with a reliable and traceable solution for implementing IP 646 particle counting methods.
