scope:
Provides 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. It complements the common criteria in part 1. Guidance is given on the organization and contents of the equipment manual, the calibration and maintenance files and the measurement procedure document. It provides information on 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. It gives information on experimental procedures suitable for the assessment of equipment accuracy, 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.
