BS EN 10242 is the British and European standard specifying requirements for the design, manufacture, and performance of threaded pipe fittings in malleable cast iron. These fittings are typically used for the transmission of fluids and gases in general-purpose applications. Standard Status and Access

When reviewing the standard, several key technical elements are defined to ensure uniformity across manufacturers: BS EN 10242 is the British and European

Surface Finishes: Available in "black" (natural) or hot-dip galvanized versions. Galvanized coatings must average about 70 μm in thickness for corrosion resistance. Threading & Design Standards

Precision in threading is critical for pressure-tight seals: Blackheart Malleable Iron (White Iron Core): This is

  1. Blackheart Malleable Iron (White Iron Core): This is the most common type used in general plumbing. The fracture surface appears dark (black) due to the presence of temper carbon nodules, while the outer skin may remain white. It offers good shock resistance and ductility.
  2. Whiteheart Malleable Iron: This material is decarburized during annealing, resulting in a largely ferritic structure with a fracture surface appearing silvery-white. It is often preferred for specific welding applications.

3.2 Designation

Under the standard, materials are designated by a symbol indicating the tensile strength. For example, a typical designation might be B 30-06, where:
