Threads are the most critical point of connection. BS EN 10242 enforces strict compliance with or BS 21 thread profiles:
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.

BS EN 10242 classifies fittings based on their pressure-temperature performance. The standard specifies a designated working pressure often referred to as or Design Symbol A .
In real-world applications, BS EN 10242 is referenced throughout project documentation—from initial design to system handover. When you see a call for a "BS EN 10242" fitting in a specification, you know it requires: Threads are the most critical point of connection
The standard strictly governs the chemical composition and mechanical properties of the malleable cast iron used. This ensures that all fittings have consistent quality, strength, and durability.
is the British adopted European standard titled: "Threaded pipe fittings in malleable cast iron and cast steel with expanded content." The standard specifies a designated working pressure often
For engineers, procurement officers, and quality assurance managers, having the official PDF document on hand is essential for several reasons:
Whether you are designing a heating system, a factory air line, or an offshore gas skid, the integrity of your threaded joints begins with compliance to . Get the PDF, read it thoroughly, and never guess a dimension again.
: The standard has been recently updated. The newest version is BS EN 10242:2025 , which officially supersedes the long-standing BS EN 10242:1995 version.
Designed to create a pressure-tight joint by mating with a parallel or taper internal thread.
