In reliability engineering, few indicators are as consistently revealing as the particles that infiltrate a lubrication system. Long before vibration, temperature, or performance changes become ...

ISO 11171 has functioned as the benchmark for particle counting in hydraulic fluids and lubricants for many years. It details the use of Light Obscuration (LO), a method that measures particle size by ...

Automated Particle Counters (APCs) calibrated with Medium Test Dust (MTD) have historically set the benchmark for fuel and lubrication cleanliness testing. This calibration method is based on ISO ...

Being able to verify the quality of lubricants is crucial for ensuring engine functionality. Credit: 3d_illustrator via Shutterstock. Lubricants and coolants are critical in engines to minimise the ...
