The technical framework supporting the accreditation action of the ENEA ION-IRP radon service
Among the general requirements to accredit a radon measuring service, outlined in the international standards as EN ISO/IEC 17025, the technical requirements play the main role in the quality assurance of a testing service. The reliability of the assessment of the radon air concentration in workplaces and dwelling is determined by many factors the most important being the physical measuring met...
متن کاملENEA Reference Atmosphere Facility for Testing Radon and Daughters Measuring Equipment
This paper gives the technical characteristics of the Italian Committee for Research and Development of Nuclear Energy and Alternative Energy (ENEA) radon chamber and the operational procedures developed for testing radon and daughters measuring equipment. Runs were carried out under different experimental conditions defined in terms of radon and daughter concentrations, equilibrium ratio (F-fa...
متن کاملFacility Calibration Unit Functional Requirements (v1.1)
Page 1 This report is intended to summarize basic functionality requirements for the facility calibration unit. The specifications outlined here are derived from material reviewed at recent IRISWG, OISWG, and GSC meetings, during September and October, 1994, as well as from individual contributions. The main difference between V1.0 and V1.1 of this document is that I have structured V1.1 on an ...
متن کاملMicro-Flow Calibration Facility at NIST
The Fluid Metrology Group (FMG) at the National Institute of Standards and Technology (NIST) is developing a primary, dynamic gravimetric liquid flow standard for use in the range 100 nL/min to 1 mL/min (and eventually lower). An elevated reservoir of water with a pressure head of a few centimeters provides a flow to the meter under test and the discharged water from it flows to a micro-balance...
متن کاملA Transient Electromagnetic Flowmeter and Calibration Facility
Flowmeter and Calibration Facility P.J. Lefebvre Naval Underwater Systems Center, Newport, R.1. An electromagnetic flowmeter was developed to measure transient flows at a data rate of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics ofa commercially available electromagnetic flowmeter normally used W. W. Durgin for steady-state operation. Use of the comme...
