This European Standard applies to the design, construction, equipping, marking and testing of air locks as defined in 3.4 and pressure bulkheads as defined in 3.5, which are to be used in tunnelling work. An oxygen breathing system used to provide the breathing supply necessary to conduct a safe decompression is also covered by this standard.
NOTE When an air lock is designed for the use of non air breathing mixtures (e.g. Heliox) a specific risk assessment is required.This standard deals with all significant hazards, hazardous situations and events relevant to air locks and pressure bulkheads, when they are used as intended and under the conditions foreseen by the manufacturer as listed in clause 4. This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
This document is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN. This European Standard does not cover the supply of services to the air lock. Vibration and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks.
