The overarching body for EN standards.
Malleable cast iron is highly valued in engineering because it combines the castability of gray iron with the toughness, ductility, and tensile strength of steel. This makes BS EN 10242 fittings highly resilient against mechanical stresses, thermal expansion, and high internal pressures. Key Technical Specifications of BS EN 10242
: Suitable for large-scale heating and cooling systems that experience significant temperature fluctuations. Compliance and Certification Manufacturers must perform rigorous testing, including leak tightness hydrostatic pressure tests
(a type of fitting), as these are common components covered under the standard's mechanical and design specifications. ValvesTubesFittings.com Key Specifications of BS EN 10242 Material Grades: Standardizes malleable cast iron types, including Whiteheart (EN-GJMW) and Blackheart (EN-GJMB). Thread Types: Covers threaded connections following (pressure-tight on the threads) or EN ISO 228-1 (fastening threads requiring a gasket). Design Symbols:
BS EN 10242 remains the foundational benchmark for threaded malleable iron fittings across Europe and global markets adhering to British standards. By explicitly defining material properties, thread geometry, and the strict parameters of hot-dip galvanizing, the standard ensures that plumbing networks operate safely, reliably, and hygienically—especially when conveying vital drinking water resources. When compiling project specifications, always invest in an official, updated copy of the standard to ensure absolute regulatory compliance and engineering accuracy. bs en 10242 pdf portable
BS EN 10242 specifies the technical delivery conditions for threaded fittings (elbows, tees, couplings, caps) made of malleable cast iron. It covers:
: Specifications covering jointing threads (such as EN 10226-1 parallel internal Rpcap R sub p and tapered external ) and fastening threads under EN ISO 228-1. Technical Specifications: Ratings & Coatings
The standard covers pipes made from (formerly known as spheroidal graphite cast iron).
Enables CAD designers to use precise, standardized dimensions when modeling piping systems. The overarching body for EN standards
Defines specific dimensions for elbows (90 deg, 45 deg), tees, couplings, unions, sockets, caps, and plugs.
Covers material properties, galvanizing requirements (if applicable), and dimensional tolerances.
The standard covers a wide variety of fitting types, such as:
Note: Always seek licensed copies from BSI or authorized resellers to ensure you are using the most accurate and technical information. Summary of Benefits Key Technical Specifications of BS EN 10242 :
The standard specifies the technical requirements for threaded pipe fittings made of malleable cast iron . In essence, it is the rulebook for the elbows, tees, unions, and other connectors used in countless piping systems.
BS EN 10242:1998 is a British Standard that specifies the requirements for malleable cast iron fittings used in pipelines for conveying fluids, such as water, gas, and oil. The standard is a UK implementation of the European Standard EN 10242:1998.
