ÖNORM EN 1127-1

This European Standard specifies methods for the identification and assessment of hazardous situations leading to explosion and the design and construction measures appropriate for the required safety. This is achieved by hazard identification; risk assessment; elimination or minimization of risk; information for use. The safety of equipment, protective systems, and components can be achieved, as described in 5.7 of EN 414:1992, by removal of hazards and/or limiting the risk, i.e. a) by design without using safeguarding; b) by safeguarding; c) by communication links if necessary to convey information to the user; d) by any other precautions. NOTE: The design in accordance with 5.7 of EN 414:1992 should not be confused with the design in accordance with 6.5 of this standard. Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in clause 6 of this standard, measures according to c) against explosions are dealt with in clause 7 of this standard. Measures in accordance with d) are not described in this standard. They are dealt with in clause 6 of EN 292-2:1991. The preventive and protective measures described in this standard will not provide the required level of safety unless the equipment, protective systems, and components is operated within its intended use and is installed and maintained according to the relevant codes of practice or requirements. This standard specifies general design and construction methods to help designers and manufacturers in achieving explosion safety in the design of equipment, protective systems and components. This standard is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres. These atmospheres can arise from flammable materials processed, used or released by the equipment, protective systems and components or from materials in the vicinity (. (. (...abbreviated)
