ISO 12103-2 M2 Test Dust

Product Introduction:

Particle Technology Fuel Contamination Test Dust offers a full range of fuel contamination test materials used to test the reliability of components of fuel and hydraulic oil systems in the aerospace and automotive industries. Typical mixtures of contaminants tested within the fuel system range from iron oxidation (rusting) to carbon fiber rods, graphite epoxy composites and fire extinguishing foams.

Standards:

ASTM E1226-22， IEC 60079-20-2:2022， ISO 6184-1:2023， EN 14034-4:2021， NFPA 68:2023，ISO 12103-2

Advantages:

Particle Technology UK has considerable experience in testing dust for fuel pollution to meet UK, EU, US, Japanese and international standards. The test dust can also meet Arizona dust, regardless of particle distribution and composition, to meet the specific requirements of the customer. Standard tests simulate dust from deserts to cities, from natural gas pipelines to jet fuel, and from railroads to airplanes. This allows you, as a customer, to test your product in real-life situations to highlight its advantages.
