Requirements for cast grey or ductile iron spigot and socket pipes manufactured by either the sand-cast or the spun process, with either Type A or Type B sockets.

This Part of BS 416 specifies cast grey or ductile iron spigot and socket pipes manufactured by either the sand-cast or the spun process, with either Type A or Type B sockets (see Table 1). This Part of BS 416 also specifies sand-cast fittings.

These pipes and fittings are for use above ground (see 2.1) in discharge or ventilating pipe systems in buildings.

This Part of BS 416 specifies quality of material, critical dimensions and tolerances, coating and marking. A leakage test is included.

For the convenience of specifiers and purchasers, a list of options available to them within the standard is given in Appendix A.

NOTE 1 Plan views of pipes and fittings are given in Figure 1 to Figure 4. Typical designs for pipes and fittings are illustrated in Figure 5 to Figure 31 in Appendix B. Dimensions are illustrated on the figures (where appropriate) and are given in the tables accompanying those figures (see Table 1 to Table 27).

Specifications for coatings are included by reference (in item d) of clause 3) to existing British Standards and, for materials not covered by those standards, by a requirement for a manufacturer’s certificate of suitability.

NOTE 2 The pipes specified may be used as rain-water pipes when a heavier grade of pipe than that specified in BS 460 is required.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
