3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

4 Classification

4.1 According to the way the extinguishing equipment is installed it is divided into: a) floor-standing extinguishing equipment; b) suspended extinguishing equipment.

4.2 According to the type of limit on the discharge port temperature it is divided into: a) temperature-restricted extinguishing equipment; b) non-temperature-restricted extinguishing equipment.

5 Model designation

The model designation is composed as follows: QRR for condensed aerosol fire extinguishing equipment; then the nominal mass of the compound forming the aerosol fire extinguishing agent, in kilograms (kg); then the extinguishing category, AM for the surface fire of a wood crib, B for a class B fire and AJ for a polymer fire; then the way the extinguishing equipment is installed, L for floor-standing and G for suspended; then the type of limit on the discharge port temperature, not marked for the non-temperature-restricted type and W for the temperature-restricted type; and finally the manufacturer’s own designation.

Example 1: QRR3AMBL denotes non-temperature-restricted, floor-standing condensed aerosol fire extinguishing equipment able to extinguish the surface fire of an AM wood crib and a class B fire, with a nominal mass of the aerosol forming compound of 3 kg.

Example 2: QRR1AMGW denotes temperature-restricted, suspended condensed aerosol fire extinguishing equipment able to extinguish the surface fire of an AM wood crib, with a nominal mass of the aerosol forming compound of 1 kg.
