26、- EN 15266:2007 (E) 5 Introduction This European Standard contains the general safety requirements relating to the safety of persons, animals and property and the protection of their environment. The requirements of this standard concern designers, manufacturers, suppliers and importers of stainless
27、 steel pliable corrugated gas tubing kits for buildings. Installation and mandatory strength and tightness tests before commissioning should consider the local application regulations where they exist. This document is applicable to: new installation pipework; replacements of existing installations;
28、 or extensions to existing installations. Stainless steel pliable corrugated gas tubing kits can be used in conjunction with other approved gas pipework.
