GUIDELINES AND DOCUMENTS CONCERNING UNCERTAINTY OF MEASUREMENT RESULTS

 

This is a first list of useful documents and a first result of the project which started on April 1, 2000. The list will be completed as the project goes on.
  1. Use of statistics to develop and evaluate analytical methods.

    2. G.T.Wernimont. AOAC, Arlington, VA, 1987.
    Useful for the evaluation of uncertainty from interlaboratory studies.

  2. Guidelines for evaluating and expressing the uncertainty of NIST measurement results

    3. NIST Technical Note 1297 – 1994.
    Can be downloaded from: http://physics.nist.gov/cuu/Uncertainty/bibliography.html

    Largely based on the GUM (see 3) with the aim to have a single approach at NIST to the expression of uncertainty.
  3. Guide to the expression of uncertainty in measurement (GUM)

    4. ISO 1995
    The development of this guide was supported by the following seven organisations : BIPM, IEC, IFCC, ISO, IUPAC, IUPAP, OIML
    Error components that are considered important are separately identified and quantified (bottom-up approach). These are then combined to obtain an overall uncertainty.
    Written by physical metrologists and therefore primarly developed for reporting uncertainty in physical measurements.
  4. Quantifying uncertainty in analytical measurement.

    5. EURACHEM 1995
    P.O. Box 46, Teddington, Middlesex TW11ONH
    Can be downloaded from : http://www.vtt.fi/ket/eurachem

    The ISO bottom-up approach is applied to analytical chemistry.
  5. Uncertainty of measurement – implications for its use in analytical science
    6.
    The Analytical Method Committee ,Analyst 1995, 120, 2303.
    The AMC of the Royal Society of Chemistry (RSC) proposes a top-down approach for the evaluation of uncertainty in an analytical laboratory. Information from interlaboratory studies is considered here to obtain an overall estimate of uncertainty. Deals only with general principles of the subject.
  6. Statistical aspects of the certification of chemical batch SRMs

    7. NIST Special publication – July 1996.
    Discusses the uncertainty of certified values. Illustrated with different examples.
  7. The expression of uncertainty in quantitative testing

    8. European cooperation for Accreditation of Laboratories (EAL)
    EAL-G23, edition 1 August 1996
    Can be downloaded from: http://www.european-accreditation.org/

    (BELTEST is the Belgian member of EAL)
    Refers to the GUM (see 1) and the EURACHEM-1995 (see 2) documents.

  8. Harmonized guidelines for the use of recovery information in analytical measurement

    9. IUPAC
    Resulting from the symposium on Harmonisation of Quality Assurance Systens for Analytical Laboratories, Orlando, USA, 4-5 September 1996 held under the sponsorship of IUPAC, ISO, and AOAC International
    Includes proposals for uncertainty in reporting recovery.
  9. Estimation and expression of measurement analysis in chemical analysis

    10. Nordic Committee of Food Analysis (NMKL procedure No5 (1997))
    The approach is based on experimental data generated in the individual laboratory. The measurement uncertainty is estimated on the basis of the time-different intermediate precision. Since reproducibility is not taken into account the estimated measurement uncertainty applies only to an individual laboratory’s own random errors.
  10. Metrology in chemistry and biology – A practical approach

    11. BCR (1998)
    A section on unertainties is included
  11. Quantifying uncertainty in analytical measurement
    12.
    Draft EURACHEM/CITAC guide - second edition june 1999
    Can be downloaded from : http://www.european-accreditation.org
    The second edition stresses that the procedures introduced by a laboratory to estimate its measurement uncertainty must be integrated with its existing quality assurance measures. It attempts to correct the impression gained within the analytical community that it is only the so-called component-by-component approach to the estimation of measurement uncertainty that is acceptable to the customers of providers of analytical data.
  12. Harmonised guidelines for the in-house validation of methods of analysis

    13. IUPAC
    Report of the FAO,IAEA, AOAC International and IUPAC workshop on "Principles and practices for method validation", 4 to 6 November 1999, Budapest, Hungary.
    Provides information concerning uncertainty estimation from validation studies.
  13. Protocol for uncertainty evaluation from validation data - January 2000

    14. V.J. Barwick, S.L.R. Ellison
    LGC/VAM/1998/088
