Safety requirements, associated test methods and thermal efficiency of gas heating equipment of machines wherein water is either heated by an integral gas burner or by circulating hot water from an adjacent heater, or where a separate heater supplies rinse water.

This British Standard specifies safety requirements and associated methods of test for the gas heating equipment of the following types: dishwashing machines where water is heated by an integral gas burner; dishwashing machines where water is heated by circulating hot water supplied from an adjacent gas water heater; dishwashing machines where rinse water is supplied by a separate gas water heater. It also specifies requirements for the efficiency of the water heating equipment on these machines. For appliances of the types specified in b) and c) the requirements are mainly satisfied by reference to the appropriate British Standard, but certain additional requirements are detailed to make them suitable for use in this particular application. In specifying requirements for these appliances it is assumed that the gas supply pressure available at the inlet to the appliance will be within the following range under normal operating conditions. Family Pressure range mbara 1st 7.5 to 25 2nd 17.5 to 27.5 3nd butane 28 to 35 propane 37 to 45 a 1 mbar = 102 N/m2 = 0.1 kPa. Requirements for controls given in this standard relate to those fitted as part of, or supplied with, particular appliances: they do not necessarily provide a complete specification for controls intended for general use and tested separately. The attention of manufacturers and installers of equipment covered by this standard is drawn to additional requirements contained in the Health and Safety at Work etc. Act, 1974, in local authority regulations, with particular reference to water supply, in the Factories Act, in the Gas Safety Regulations 1972, in the Building Regulations issued by the Department of the Environment and in the Building Standards (Scotland) (Consolidation) Regulations issued by the Scottish Development Department. Guidance on preferred dimensions may be found in PD 6444.
