The National Environmental Balancing Bureau has updated its fume hood performance testing standard.

Officials say the goal of the second edition of the standard is to make fume hood testing more uniform and the changes reflect some of the unique challenges of testing the products.

“The new edition of the fume hood procedural standard reflects the latest methods and technology in the industry,” said Mike Kelly, chairman of the NEBB fume hood committee. “We anticipate that it will be a valuable guide for those performing and specifying fume hood testing and will serve to enhance the quality of the work performed.”
