BS 9251 thus aims to extinguish small fires or contain growing fires until the fire and rescue service arrives by reducing the rate of heat and smoke generated

The slow moving test has been designed to minimise these effects

This part includes the insulating liquid to air heat exchangers used in the cooling circuits of power transformers and reactors

BS 4142 on industrial and commercial sound is used to assess the impact of industrial and commercial sound

The method has been used in high air concentrations successfully with a higher reagent concentration in an impinger

BS EN 17192 discusses ventilation for buildings. Ventilation not only affects physical health, it also impacts the mental health of the occupant. Sometimes effects of exposure to CO are subtle, and occupants do not realize what may be causing their symptoms. Due to this, it is important to test ventilation for buildings. BS EN 17192 specifies methods to test rigid or semi rigid non metallic ductwork under laboratory
