The standard explicitly excludes fittings with alternative permanent coatings or any coating applied over a hot-dip galvanized layer.
When sourcing fittings, verifying compliance is straightforward.
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 . Bs En 10242 Pdf

Galvanized versions offer long-lasting service in harsh environments. Accessing the BS EN 10242 PDF
A key feature of BS EN 10242 is its defined , which are typically presented in a graph within the standard (see Figure 4 of the document). For instance, Class 150 fittings are generally rated for a working pressure of 25 bar within a temperature range of -20°C to 120°C. National standards bodies (like DIN, AFNOR, or UNE)
The standard covers a comprehensive range of fittings, including elbows, tees, couplings, unions, and plugs. BSI Knowledge Size Range: Covers threaded fittings from 1/8" to 6" (DN 6 to DN 150).
Represents the highest tier. Fittings in this class feature specific whiteheart or blackheart iron grades, precise ISO 7-1 taper/parallel threads, and undergo rigorous individual leak testing. This class is preferred for critical gas and hazardous fluid transport.
Designed to create a pressure-tight joint by mating with a parallel or taper internal thread. BS EN 10242 classifies fittings based on their
