  • Slide 1

    International Standards

    Creating CONFIDENCE for the Peoples and Nations

    of the World

    Detection Methods and Reference Materials Symposium – October 2015

  • Definition of a Standard

    • A published specification that establishes a common language, and contains a technical specification or other precise criteria and is designed to be used consistently, as a rule, a guideline, or a definition

    (British Standards Institution)

    Slide 2 Detection Methods and Reference Materials Symposium – October 2015

  • Examples of Standards

    • A set of specifications (criteria) that sellers and buyers agree to; usually a mix of physical and chemical parameters

    • Methods of analysis (technology and procedures) used to determine if the specifications have been met

    • Buyers and Sellers use standards to facilitate equitable trade

    Slide 3 Detection Methods and Reference Materials Symposium – October 2015

  • Standards cover many activities

    • Standards cover a vast array of subjects and topics.

    • Include products and services of almost every description.

    • Some libraries contain over half a million standards!

    methods for DNA and Protein identification

    • Government driven

  • Laboratory Accreditation • Laboratories may be accredited under official accreditation

    schemes – ISO (17025) – not equally applied – ISTA – National schemes (e.g. COFRAC, UKAS, CNAL, QUACERT, SAC-

    SINGLAS)

    • Accredited laboratories validate/verify methods for use in their own laboratory and participate in proficiency tests (check sample programs organized by e.g. ISTA, GIPSA, FAPAS, AOCS, AACC...) as part of the accreditation maintenance scheme

    • Calibrate pipettes, instruments (temps) etc.

    • Use Rules, Methods and Procedures

    • Identify and Correct Deficiencies

    Slide 23 Detection Methods and Reference Materials Symposium – October 2015

  • Standards can contribute to Harmonisation by providing guidance

    On • Method development best practices • Laboratory best practices • Validation of methods • Proficiency testing • Interpretation of Results • and by providing Analytical methods

  • Standards help Harmonisation

    • Guidance on operation of laboratories • Criteria for method performance • How to determine if methods are fit for

    purpose • Measurement Uncertainty • Methods Goal of standards -> methods performing to the same criteria, and with the same results, globally
