Every single fitting must undergo a pneumatic pressure test (typically at a minimum of 5 bar while submerged in water) or an equivalent hydrostatic test to ensure there are no casting defects or porosity leaks.

The standard is the European specification for threaded pipe fittings manufactured from malleable cast iron . First published in 1995 to harmonize European piping requirements, it replaced older national standards like BS 143 and BS 1256 for most common fitting types. A PDF of this standard provides technical guidelines for the design, material composition, and performance of these fittings used in the transmission of fluids and gases. 1.

These fittings are widely used in robust, general-purpose piping systems:
The standard dictates the use of high-quality malleable cast iron. Malleable iron starts as white cast iron, which is then subjected to an annealing heat-treatment process. This process transforms brittle iron into a ductile material capable of absorbing stress and resisting fracturing under pressure.
