    Abstract - (Show below) - (Hide below)

    Specifies safety requirements for laboratory fume cupboards and test methods used to determine their performance. Siting and maintenance requirements are specified and guidance is given on the use of the fume cupboard.

    Scope - (Show below) - (Hide below)

    This Standard specifies safety requirements for fume cupboards and the methods of test to be used to determine their performance. Appendix A describes typical materials used in the construction of fume cupboards and includes recommendations and requirements on material suitability. Fume cupboards covered by this Standard are intended primarily for use in general chemical operations but may be used for the special applications set out in Appendix B, provided that the additional relevant features described therein are incorporated. Recirculating fume cabinets (which recirculate air and do not extract to the outside atmosphere) are not included in this Standard (see AS 2243.9).NOTE: Appendix C lists documents relating to the subject of this Standard. Appendix D provides recommendations for the procurement of a fume cupboard.
