Specific technical criteria for the assessment of laboratories to undertake steady-state heat transfer property measurements on circular pipe insulation according to EN ISO 8497:1994, are provided in this Standard. Complements the common criteria in Part 1. Guidance is provided on the contents and organisation of the equipment manual, the maintenance and calibration files and the measurement procedure document. Mandatory equipment performance specifications, on equipment description and on calculations for the equipment design and error analysis based on both EN ISO 8497:1994 on circular pipe apparatus and on Part 2 of this standard on the assessment of guarded hot plate apparatus information is provided. Details experimental procedures suitable for the assessment of equipment accuracy.
