This Japanese Industrial Standard specifies the carbon steel tubes, alloy steel tubes, austenic stainless steel tubes and nickel-chromium-iron
This European Standard specifies the additional requirements and test methods for gas-fired air heaters which are designed so that water vapour condenses from combustion products. On this subject, it extends the European Standards EN 778 and EN 1319 for domestic air heaters,...

Deposits on heat transfer surfaces reduce efficiency of the heat exchanger affected. A method for easily determining the corrosion and fouling tendency of a particular water under heat transfer conditions will allow the evaluation of changes in the various system variables such as heat flux, flow...
This Japanese Industrial Standard specifies seamless nickel-chromium -iron alloy tubes (hereafter referred to as tubes) to be used, for example for heat exchangers or condensers in chemical and petroleum industries, and steam generators in nuclear industry, where the tube is designed for exchanging...
Requirements for plain end, seamless and welded, tubes, not exceeding 127 mm outside diameter and not exceeding 12.5 mm thickness, for use in boilers and super heaters.
Eight flasks (sizes, material, construction, dimensions and inscriptions); three Crow receivers (sizes, material, construction, dimensions, graduations); three types of draught screen; three types of condenser; auxiliary equipment (heaters, thermometer, flask support boards). Guidance on...
This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus. Quantitative heat release measurements provide information that can be used to compare wall or ceiling...
Requirements for stationary non-instantaneous electric water heaters. Manufacturers submitting appliances to the BEAB for approval to BS 3456 are required to provide evidence of compliance with this standard from the United Kingdom's Water Fittings Byelaws Scheme.
This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus. Quantitative heat release measurements provide information that can be used to compare wallcoverings and...
4.1 Automobile and truck radiators and heater cores are now predominantly made with aluminum alloys using various manufacturing processes including brazing with a flux (See Appendix X1 for additional information). The presence of residual internal brazing flux in heat exchangers along with...
This European Standard specifies dimensions, materials and performance requirements (including methods of test) for in line hot water supply tempering valves for sanitary hot water systems, of nominal sizes from DN 15 to DN 50. Tempering valves reduce the temperature of sanitary hot water for...

This International Standard specifies a method suitable for the production control or product development purposes for assessing the heat release rate of essentially flat products exposed in the horizontal orientation to controlled levels of radiant heating with an external igniter. The heat...
This European Standard specifies dimensions, materials and performance requirements (including methods of test) for expansion valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion valves are intended for fitting to the cold water...
This European Standard specifies dimensions, materials, and performance requirements (including methods of test) for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure safety valves are intended for fitting to...
