CONOSTAN - Lubricant Condition Monitoring Standards
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, recently updated (2010) procedure, secondary calibration requires a fluid tracable to NIST SRM 2806 - a suspension of 3.3 mg/L of ISO medium test dust in super-clean hydraulic fluid. CONOSTAN® offers a full range of cost-effective products for the periodic calibration and verification of automatic particle counters, as per Clause 6 and Annexes A through E of ISO 11171. Partistan™ secondary standards are compliant with ISO 11171 and directly tracable to NIST SRM 2806.
