BS EN 12097 on ductwork maintenance requirements for building ventilation  is relevant to:

BS EN 12281:2002 includes some technical changes with respect to DD ENV 12281:1997

The test can be carried out with either dry or wet hardened concrete substrates

The purpose of BS EN 16796-4 is to give guidelines for conducting fuel consumption tests on industrial trucks is for accessing their energy efficiency

Annex B gives rationales for the liquid-phase test method for low-temperature steam and formaldehyde biological indicators
