Read the library in the right order.

Each path is a sequence of articles chosen and ordered for one job. Follow it top to bottom, or jump in where you are.

  1. Path 0112 articles · 24 min

    Temperature mapping from scratch

    Plan, run, analyse and report a mapping study that stands up to a GDP or GMP inspection — in the order the work actually happens.

    For: QA, validation and facilities engineers running their first (or first defensible) mapping study.

    Start the path
  2. Path 0210 articles · 20 min

    Measurement uncertainty fundamentals

    From the vocabulary to a finished, correctly rounded budget: everything the GUM asks of a calibration user, without the algebra getting in the way.

    For: Calibration technicians, laboratory staff and engineers who must build or check an uncertainty budget.

    Start the path
  3. Path 039 articles · 18 min

    Reading and using calibration certificates

    What every line on an accredited certificate means, how to judge whether an instrument is fit for use, and how to catch a weak certificate before it reaches your records.

    For: Anyone who receives calibration certificates: quality, metrology, maintenance and purchasing.

  4. Path 0410 articles · 20 min

    ISO/IEC 17025 for calibration users

    The clauses of ISO/IEC 17025 that shape what an accredited laboratory can and must give you — traceability, uncertainty, reporting and scope.

    For: Customers of accredited laboratories and staff preparing an in-house laboratory for accreditation.

  5. Path 0511 articles · 22 min

    GDP cold-chain compliance

    Storage conditions, qualification, monitoring, excursions and data integrity — the temperature-control expectations of EU GDP and WHO guidance in one sequence.

    For: Responsible persons, QA and logistics teams at wholesalers, 3PLs and pharmacies.

  6. Path 0611 articles · 22 min

    Temperature calibration in practice

    Bench-level technique for PRTs, thermocouples and loggers: sources, immersion, self-heating, hysteresis, references and the ice point.

    For: Laboratory technicians and engineers performing or specifying temperature calibrations.

    Start the path
  7. Path 079 articles · 18 min

    Qualification and validation essentials

    URS to requalification under Annex 15, with the protocol structure, deviation handling and software validation that inspectors expect.

    For: Validation engineers, QA and project teams commissioning temperature-controlled equipment and monitoring software.

    Start the path
  8. Path 089 articles · 18 min

    Choosing and maintaining temperature equipment

    Loggers, sensor classes, sources, readouts and fixed points — what to buy, what the specifications mean and how to keep it all within its assumed performance.

    For: Laboratory managers, metrologists and engineers specifying or maintaining measurement equipment.
