This draft European Standard, applies to both types of fibre-cement pipes AT and NT as defined in EN 512:1994, gives installation recommendations for this pipelines in above or below ground situations. It complements the general principles for all types of water supply systems specified in EN 805:2000, "Water supply - Requirements for systems and components outside buildings", and should be used in conjunction with that standard. This standard gives guidance in on-site working methods and in the selection and use of approved tools for cutting and machining fibre-cement pipes. This standard does not cover the following : a) installation by thrust boring and pipe jacking methods which require the use of highly specialized techniques ; b) problems caused by the use of special installations procedures (e.g. removal of pile sheeting in very deep trenches, etc.).
