EN 54

The product standards define product characteristics, test methods and performance criteria against which the effectiveness and reliability of every component of fire detection and fire alarm system can be assessed and declared.

This is obvious since CEN numbers the European standards in numerical ascending order according to the date of project registration.

[3][4] The EN 54 series has been prepared by Technical Committee CEN/TC72 "Fire detection and fire alarm systems" of the European Committee for Standardization (CEN, French: Comité Européen de Normalisation).

These include burning liquids, plastics and cellulosic (wood) materials, and glowing and smouldering fabrics.

The EN 54-20 defines the following test fires with reduced fuel quantity for aspirating smoke detectors with enhanced or very high sensitivity (class A or B): For flame detectors according to EN 54-10, the liquid fires TF5 and TF6 are used.
