Specifies requirements for copper cylinders of 3 grades and 7 sizes for the storage of hot water. The minimum storage capacities are from 86 L to 196 L. The cylinders are of the type in which the bottom is domed inwards.

This Part of this British Standard specifies requirements for copper cylinders, with or without the optional features listed in clause 11, for the storage of hot water, where the water is heated indirectly by the water circulating in an integral primary heater of annular or coil type and for which only one feed cistern is required, the feed water to the primary circuit being obtained from within the cylinder through the primary heater. Three grades and seven sizes are specified. The minimum storage capacities are from 86 L to 196 L. The cylinders are intended for fixing in the vertical position and are all of the type in which the bottom is domed inwards.

The information to be supplied with any enquiry or order is set out in Appendix A.
