BS EN 10242 is a British Standard that specifies the requirements for malleable cast iron fittings, including their design, materials, manufacturing process, testing, and inspection. The standard is titled "Malleable cast iron fittings for pipes under pressure - Specification" and is published by the British Standards Institution (BSI). Bs En 10242 Pdf

By standardizing the density of the iron and the thread engagement depth, the standard ensures that the fitting fails at a pressure significantly higher than the system's design pressure, providing a safety factor.

For terminating lines or reducing connection sizes.

The "centrifugally cast" method refers to the manufacturing process where molten iron is poured into a rotating mold. The centrifugal force pushes the metal against the mold wall, resulting in a dense, high-quality casting with a fine grain structure, free from the common defects found in static casting methods. BS EN 10242 is a British Standard that
