Theoretical and Practical Comparison of the Potassium Iodide Tracer Method (KI-Discus) for Assessing the Containment Efficiency of Fume Cupboards with the Gas Tracer Method Described in BS 7258: 1994: Part 4

摘要

Attempts have been made by manufacturing groups, health and safety legislators and national and international standards bodies to standardise containment testing strategies for open fronted containment systems. It is important that all the strategies and testing methods used should yield comparable results. However, there are a number of text methodologies that have not been standardised or correlated, and the results between them cannot be compared.
