at a maximum elevated temperature of 300°C. 3. Surface Coatings and Corrosion Protection

If you are sourcing, designing, or installing piping systems, understanding this standard is essential. This comprehensive guide covers the scope, material requirements, design specifications, and practical applications of BS EN 10242. What is BS EN 10242?

Key points:

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. Bs En 10242 Pdf

BS EN 10242 specifies the requirements for the design, performance, and testing of threaded pipe fittings malleable cast iron

For joining two straight pipe segments.

Represents the highest tier. Fittings in this class feature specific whiteheart or blackheart iron grades, precise ISO 7-1 taper/parallel threads, and undergo rigorous individual leak testing. This class is preferred for critical gas and hazardous fluid transport. at a maximum elevated temperature of 300°C

The current version of this standard is (which incorporated later amendments), though it is gradually being superseded by the updated BS EN 10242:2025 . It replaced earlier UK standards like BS 143 and BS 1256, although parts of those remain valid for specific copper alloy fittings not covered by EN 10242.

Under the standard, materials are designated by a symbol indicating the tensile strength. For example, a typical designation might be , where:

The standard specifies various requirements for socket weld fittings, including: Table 5 (or equivalent) in the PDF provides

The BS EN 10242 document outlines rigorous engineering baselines that manufacturers must meet to achieve certification. 1. Material Composition

For fittings exposed to moisture or corrosive elements, hot-dip zinc galvanizing is specified. The standard outlines:
