Each digit relates to a particular feature of the product measured against the standards performance requirements.Digit (1) – Category of use:’3′ denotes the unit is for closing doors from at least 105.’4′ denotes the unit is for closing doors from 180 open.Digit (2) – Durability:’8′ successfully completed 500,000 test cycles.Digit (3) – Test door mass/size:Seven grades are identified as shown in the table below (where acloser provides a range of power sizes both the minimum andmaximum sizes shall be shown):Power size Test door mass Recommended door leaf width1 20kg 750mm2 40kg 850mm3 60kg 950mm4 80kg 1100mm5 100kg 1250mm6 120kg 1400mm7 160kg 1600mmDigit (4) – Fire behaviour:’0′ denotes the unit is NOT suitable for use on fire/smoke doors.’1′ denotes the unit IS suitable for use on fire/smoke doors.Digit (5) – Safety in use:’1′ all door closer units are required to stisfy the essential requirement of safety in use.Digit (6) – Corrosion-resistance:’0′ – indicates no defined corrosion-resistance,’1′ – indicates mild corrosion-resistance,’2′ – indicates a moderate level of corrosion-resistance,’3′ – indicates high corrosion-resistance,’4′ – indicates very high corrosion-resistance.Within this section units have been tested to BS EN1154, with many units also having been tested to current Certifire testing and CE test criteria. Therefore, the 6 digit classification is shown against each of the varying units, thus indicating their performance and grading under BS EN1154.An example of the grading for a 1559 closer unit would be as follows:3 8 4/2 1 1 3(1) (2) (3) (4) (5) (6)
