PartiSTAN Particle Size Standards
PartiStan particle standards are designed for calibration and verification of automatic particle counters.
In 1999, a new calibration procedure (ISO 11171) for automatic particle counters was introduced, rendering previous procedures (i.e. ISO 4402) obsolete. With the new procedure, primary calibration requires NIST SRM 2806, a suspension of ISO medium test dust (RM 8631) in super clean hydraulic fluid.
CONOSTAN offers a secondary standard for the cost-effective calibration and verification of automatic particle counters. PartiStan secondary standards are compliant with ISO 11171 and directly tracable to NIST SRM 2806.
