cisterns up to 500 1—Specification.
BS 4213 This British Standard specifies requirements for the materials, physical properties and performance of coldwater storage cisterns and combined feed and expansion cisterns of up to 500 l capacity, from which wateris drawn for domestic purposes.It also specifies requirements for the associated fittings of such cisterns,i.e. covers, screened breathers, screened warning pipes and vent pipe entry devices, and for cistern
insulation.It gives methods of test for the evaluation of the properties of cisterns and covers made by anyof the processes currently available.
This British Standard applies only to cisterns that are manufactured from thermoplastics, and that havecovers manufactured either from thermoplastics or from other manufactured materials having a
