Provides a selection of on-site test methods for the following general purpose fume cupboards: - Fume cupboards designed in accordance with Part 2 of this European Standard and type tested in accordance with Part 3 of this European Standard. - Fume cupboards designed in accordance with Part 2 of this European Standard and not type tested.

This document specifies a selection of on-site test methods for the following general purpose fume cupboards:

  • Fume cupboards designed in accordance with Part 2 of this European Standard and type tested in accordance with Part 3 of this European Standard.

  • Fume cupboards designed in accordance with Part 2 of this European Standard and not type tested.

The test methods are designed to be used at the place of installation of the fume cupboard, usually a laboratory. They are used for commissioning after installation, for maintenance and for qualification purposes. For certain customer requirements additional or modified test methods may be necessary.

It is in the responsibility of the purchaser or user of a fume cupboard to decide which tests are to be performed. The commissioning testing can be selected and carried out from the type test methods. For routine testing, the number of test methods selected can be further reduced.
