BS EN 1295-1:1997 Structural design of buried pipelines under various conditions of loading. General requirements BS EN 1295-1 specifies the requirements for the structural design of water supply pipelines, drains and sewers, and other water industry pipelines, whether operating at atmospheric, greater or lesser pressure. In addition, this standard gives guidance on the application of the nationally established methods of design declared by and used in CEN member countries at the time of preparation of this standard. This guidance is an important source of design expertise, but it cannot include all possible special cases, in which extensions or restrictions to the basic design methods may apply. Since in practice precise details of types of soil and installation conditions are not always available at the design stage, the choice of design assumptions is left to the judgement of the engineer. In this connection the guide can only provide general indications and advice. BS EN 1295-1 specifies the requirements for structural design and indicates the references and the basic principles of the nationally established methods of design (see annexes A and B). Contents of BS EN 1295-1: Foreword Introduction 1 Scope 2 Normative references 3 Definitionss 4 Requirements 5 Basis of design procedures 6 Additional considerations for pressure pipelines 7 Influence of construction procedures 8 Design philosophies and factors of safety Annexes A (informative) Pipe definition according to cross-sectional behaviour
