5th Round Robin Test for Air Permeability Calibration Standards
PTM Technical Report
The CORESTA Physical Test Methods (PTM) Sub-Group organises a nominally annual series of round robin tests that is open to the member laboratories that have a calibration laboratory to compare their capability to calibrate standards used in physical test instrumentation. This testing provides a baseline of air permeability instrument performance across the industry and each laboratory is also able to use the result set in internal and external audit assessments.
This report covers the results of the fifth round robin test on air permeability (AP) standards conducted between June 2017 and October 2020.
