BS 4194:1967

Applies to laboratories having controlled temperature and relative humidity. Basis of design; design data required (working space, operating ranges of temperature and r.h., constructional and environmental features); testing of performance (conditions of test, stability, absence of water droplets); operation and maintenance. Appendices cover: interdependence of temperature and r.h.; specific points of design; measurement of temperature and r.h.; loaded thermocouples for temperature and r.h. measuremen t; test for stability of control settings; test for absence of water droplets; bibliography.
