What is BS EN 14222 about?
BS EN 14222 is an international standard that deals with the general requirements for stainless steam boilers.
BS EN 14222 specifies requirements for electrically heated steam boilers manufactured from stainless steel specifically dedicated to generating steam for sterilizers and disinfectors.
BS EN 14222 gives technical specifications such as design, inspection, testing, marking, requirements for equipment, safeguards against excessive pressure, materials for valves, fittings, flanges, and bolts for stainless steel steam boilers.
Note 1: BS EN 14222 covers only steam boilers that are heated by immersion heaters, and which have a maximum allowable pressure (PS) of not greater than 6 bar, a maximum volume (V) of 1000 litres, and a product of PS ∙ V not greater than 3000 bar ∙ l.
Who is BS EN 14222 for?
BS EN 14222 on stainless steel steam boilers is for:
- Manufacturers and suppliers of steam boilers,
- Manufacturers and suppliers of boiler components
- Manufacturers and suppliers of valves, fittings, flanges, and bolts for steel boiler
- Installers and service providers for stainless steel steam boilers
Why should you use BS EN 14222?
A steam boiler produces energy by heating water to generate steam. Stainless steel boilers have demonstrated their reliability and efficiency, as they have advantages like corrosion & oxidation resistance, great mechanical properties, a wide temperature range, etc.
BS EN 14222 on stainless steel steam boilers, gives you all the required technical specifications for electrically heated stainless steel steam boilers that could be used for sterilization and disinfection processes in the medical sector.
BS EN 14222 on stainless steel steam boilers, helps you ensure the safety of your instruments that may be used in laboratories, tattoo shops, dentists or in any place where the instruments need to be sterile, or autoclave is needed.
What’s changed since the last update?
