ISO/IEC 17025 (2017)

Calibration

  • The uncertainty of measurement is reported as an expanded uncertainty having a level of confidence of 95% unless stated otherwise
Service Product Determinant Technique Procedure Limitations
Flow metrology - Water flow measuring devices and systems Liquid meters Volume (and nominal flow rate) Comparison with a reference meter; Volumetric transfer

Comparison against a reference meter for medium and large meter rig

Volumetric transfer for small meter rig

Verification tests on water meters for compliance with NMI NITP 14
