2.1 ESPN final document Legal base of the classification as «out of the scope of ESP» Decree No. 99-1046 dated 13th December 1999 concerning pressure equipment Article 2 Amended by Decree No. 2007-1557 dated 2November 2007 Article 61 (JORF 3 November 2007) II. The pressure equipment defined below are not subject to the provisions of Parts II and III of this decree: h) Equipment involving casings or mechanisms for which the size, choice of materials and construction rules mainly depend on criteria of strength, rigidity and stability in terms of operating static and dynamic loads or in terms of other characteristics related to their operation and for which the pressure does not represent a significant design factor. Such equipment can include: Engines, including turbines and internal combustion engines; Steam machines, gas or steam turbines, turbine generators and compressors; Pumps and actuators; 5 2.1 ESPN final document 6
