Quality Management
esz AG’s quality management manual is dedicated to the operational organization and relevant quality management procedures regarding esz AG’s technical service offering. Utilizing the quality management manual ensures that all organizational and technical activities are planned, supervised, controlled and the accreditation body’s contractual regulations regarding calibration laboratories are in effect (at this time available in German, only).
Publishing all of our calibration procedures and measurement uncertainties establish transparency, mutual trust and traceability in all calibration reports and measurement results. This guarantees our customers consistent test equipment management and traceability. The corresponding level of transparency is unique among the industry.
Outstanding Laboratory Conditions
Industrial calibration, in particular with respect to reliable results, calls for constant and stable laboratory conditions. esz metrologists closely monitor, record and evaluate environmental conditions such as temperature and relative humidity. Results, assessment and assumptions are stored over a period of 5 consecutive years. Laboratory conditions are kept stable throughout the year, records are taken at time of calibration and included in the calibration report. esz AG’s stationary laboratory for direct current (DC) and audio frequency (AF) indicates an average temperature of 23,2 °C. The 2-sigma standard deviation is as few as 0,6 Kelvin. Thus, esz laboratories provide ideal conditions considering OEM’s standard reference temperature of 23 °C. esz AG’s dimensional laboratory reports an average of 19,7 °C at 0,5 Kelvin 2-sigma standard deviation. Little fluctuations are particularly important to evaluate temperature sensitive test objects. The average is based upon year-round data. Reported measurement uncertainties regarding relative humidity are 3 % (RH). For a complete listing of all relevant factors please refer to the document “Environmental Conditions”. In general, little to no deviation from influencing parameters will lead to more accurate results.
Unique transparency for calibration procedures, quality management and measurement uncertainties
The foundation to our quality management system is DIN EN ISO / IEC 17025 requirements „general requirements for calibration and test laboratory’s expertise / competence“.
Everybody at esz AG is committed to perform reflecting and in accordance to the defined quality policies and obejctives.
The calibration laboratories quality management is part of the organization’s quality management system. Management, together with all persons responsible for quality management, coordinates all activities, planning and executing quality management measures among all affiliated branches and business units. All together we pride ourselves in responsible developing, maintaining, improving and supervising esz AG’s quality management manual.
The quality management manual is binding to everybody here at esz AG calibration & metrology
