      <subfield code="a">A new method has been developed for testing fume hood performance in a controlled, ventilation laboratory setting or in the field during normal use conditions. It involves a steady release of a tracer material, such a sulfur hexafluoride, inside a hood through a hollow rectangular diffuser that surrounds the work and then measurement of concentration outside the hood</subfield>
