SR EN 1906:2003

This European Standard specifies test methods and requirements for spindle and fastening elements, operating torques, permissible free play and safety, free angular movement and misalignment, durability, static strength and corrosion resistance for sprung and unsprung lever handles and knobs for doors on backplates or roses. This standard is applicable only to lever handles and knobs that operate a latch or a lock. It states four categories of use according to the frequency and other conditions of use. Compliance with this European Standard ensures a margin of strength in excess of that needed for normal operation. Additional requirements are needed for special safety furniture which is suitable for use in situations where there is a high risk of falling. Since special safety furniture is not essential in every situation, this European Standard provides for additional safety requirements (see 5.13) which are only necessary when the manufacturer states that the safety furniture is claimed to conform to these requirements. This standard states five grades of security. Grade 0 ac
