The standard categorizes materials primarily into two types based on their microstructure resulting from the annealing process:
When you open a BS EN 10242 PDF, you will notice it references other standards. Do not confuse them:
| Standard | Focus | Relationship | | :--- | :--- | :--- | | BS EN 10242 | Threaded fittings (malleable iron/cast steel) | Primary document | | ISO 7-1 | Threading dimensions and gauges | Normative reference (required) | | BS EN 10204 | Metal product inspection certificates | Used for traceability | | ASME B16.3 | Malleable iron threaded fittings (USA) | Alternative (non-interchangeable) | | BS 143 & 1256 | Older British standards | Replaced and withdrawn | Bs En 10242 Pdf
Warning: Do not mix ASME B16.3 fittings with BS EN 10242 piping. The thread forms (NPT vs. ISO/BSP taper) are similar but not identical, leading to leaks.

BS EN 10242 is the British adopted European standard titled: "Threaded pipe fittings in malleable cast iron and cast steel with expanded content."
Published by the British Standards Institution (BSI) in collaboration with CEN (European Committee for Standardization), this standard specifies the technical delivery conditions, dimensional requirements, mechanical properties, and pressure/temperature ratings for threaded fittings used in transport of fluids (liquids and gases) under pressure. ISO/BSP taper) are similar but not identical, leading
CEN reviews standards every 5 years. The last major revision was published in 202X (confirm via BSI). Ensure your PDF is the current version by checking the "Status: Current" note on the BSI website.
Yes. Table 5 (or equivalent) in the PDF provides maximum allowable working pressures (MAWP) for saturated steam up to 200°C. Typically, malleable iron fittings are rated for steam at 10 bar to 16 bar, depending on size.
