assaabloy.com 645 EN 14846 – Electromechanically operated locks and striking plates EN 14846 is a comprehensive 9-digit classification system for assessing the wide range of Electromechanical locks and strike products needed to satisfy the diverse requirements of the European market. Within the EN 14846 standard, a range of performance features are assessed including normal use (and abuse) forces, long-term durability, fire/smoke resistance, corrosion, temperature and humidity resistance, and security from both physical attack and electromechanical manipulation. Electromechanical locking Legislation Legislation CATEGORY OF USE Three categories of use are identified (see below) and the forces/torques specified, reflect this: Grade 1: Low frequency of use by people with a high incentive to exercise care and a small chance of misuse, e.g. internal residential doors Grade 2: Medium frequency of use by people with some incentive to exercise care but where there is some chance of misuse, e.g. internal office doors Grade 3: High frequency of use by public or others with little incentive to exercise care and with a high chance of misuse, e.g. doors in public buildings DURABILITY Thirteen grades are identified with minimum figures for deadbolt operation (manual, automatic and electrical) and latchbolt operation (with and without side load) as shown. Deadbolt operations (manual) 10,000 25,000 50,000 Latchbolt operations and deadbolt operations (automatic and electrical) 50,000 10,000 200,00 Side load on latchbolt (No load) Grade A Grade B Grade C 10 N Grade F Grade G Grade H 25 N - Grade L Grade M 50 N - Grade R Grade S 120 N - Grade W Grade X 250 N - - Grade Y Grade Fire/smoke resistance requirement 0 No requirement (not intended for use on fire/smoke doors) A Suitable for use on smoke door assemblies B Suitable for use on smoke/fire door assemblies (> 15 minutes) C Suitable for use on smoke/fire door assemblies (> 30 minutes) D Suitable for use on smoke/fire door assemblies (> 60 minutes) E Suitable for use on smoke/fire door assemblies (> 90 minutes) F Suitable for use on smoke/fire door assemblies (> 120 minutes) Maximum closing force Door mass Up to 100kg Up to 200kg Above 200kg 50 N Grade 1 Grade 2 Grade 3 25 N Grade 4 Grade 5 Grade 6 15 N Grade 7 Grade 8 Grade 9 DOOR MASS AND CLOSING FORCE Nine grades are identified with maximum figures for closing force at various door masses as shown. Note: closing force is from a standing start: i.e. fully extended latchbolt in contact with striking plate at start of test. Durability Suitability for use on fire/smoke doors Door mass and closing force SUITABILITY FOR USE ON FIRE/SMOKE DOORS Seven grades are identified in ascending order of smoke/fire resistance as shown. SAFETY No requirement, but note: an electromechanically operated lock or striking plate conforming to this standard can, at the same time, also be part of an exit device conforming to EN 179 or EN 1125, or part of an exit system conforming to prEN 13633 or prEN 13637.
