In the world of industrial piping, precision and safety are non-negotiable. Whether you are designing a fire protection system, a natural gas line, or a hydraulic circuit, the components you choose must conform to rigorous international standards. One such critical standard is .

Design Symbol A fittings must undergo an individual pressure test using air (at a minimum of 5 bar) or hydrostatic water pressure to ensure 100% leak-free integrity before leaving the factory.
Fittings produced under this standard are designed to connect threaded pipes safely. They handle diverse media, including water, oil, gas, and steam. Why Malleable Cast Iron?
The standard dictates required elongation and tensile strength to ensure the fitting is ductile, not brittle.
Fittings made to old BS 143 are not automatically interchangeable with BS EN 10242 fittings without checking thread profile tolerances.
