Ctl structure l.jpg

CTL Structure

  • CTL’s technical scope covers over 1 200 IEC standards

  • Expert Task Forces (ETF) deal with technical issues in assigned product categories

Bahrain Workshop – December 7-8 2009


Ctl structure6 l.jpg

CTL Structure

  • CTL Working Groups

    • WG1 – Metrology and Uncertainty/AccuracyDeals with general metrological issues such as Traceability, Frequency of Calibration, Measurement Uncertainty or Accuracy or Power Supply Stability

    • WG2 – Proficiency TestingThis group works closely with the CTL Proficiency Testing Provider, IFM Australia, and develops new PT programs, helps establish the pass/failure criteria for individual programs, and helps IFM with the assessment of individual corrective actions

    • WG3 – Editing GroupEdits the CTL Decision Sheets and other technical documents as required

    • WG4 – CoordinationDeals with horizontal technical issues and develops relevant CTL Decision Sheets

CTL Decision Sheets

Use of Decision Sheets by CBTLs

  • CBTL staff must demonstrate:

    • Full understanding of the concept of CTL Decisions

    • Knowledge of CTL Decisions applicable to a particular standard and specific tests

    • Ability to navigate the CTL Website and quickly locate the Decisions

Ctl decision sheets30 l.jpg

CTL Decision Sheets

Using CTL Decisions in an Assessment

  • When specific tests are selected by IECEE Assessors for demonstration of competence by CBTL, the Technical Assessors:

    • Identify the existing applicable CTL Decisions and Provisional Decisions

    • Observe the test demonstration by the CBTL without making any reference to applicable CTL Decisions

    • Ask the CBTL staff to identify CTL Decisions only if they fail to do so on their own

    • Identify in the Assessment Report, as applicable, the need for staff training in the area of CTL Decisions
