What is BS EN 1254‑20 standard about?

BS EN 1254‑20 contains definitions, thread dimension, reference data (minimum bore), supporting information (assembling instructions) and describes the test methods of Copper and copper alloy for plumbing fittings.

Thread dimensions comprise of: wall thickness at threaded portions of fittings, dimensions of tail pipe ends for swivel fittings, dimensions of gas union connectors, thread dimensions and thread profile.

Who is BS EN 1254‑20 standard for?

BS EN 1254‑20 on copper and copper alloy plumbing fittings is beneficial for:

Manufacturers of copper and copper alloy plumbing fittings
Manufacturer and suppliers of threads
Installers
Quality assessment personnel
Civil and mechanical engineers
Trained and skilled technicians

Why should you use BS EN 1254‑20 standard?

Fittings are an important component of the plumbing system. A fitting is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating and measuring fluid flow.

BS EN 1254‑20 provides information on the test method for checking leak-tightness under internal hydrostatic pressure and internal pneumatic pressure, integrity of fabricated fitting bodies, test method for checking the resistance of joints to pull, vibration, static flexural force, under vacuum, to temperature cycling, methods for detecting non-pressed fitting ends, determination of resistance to stress corrosion.

Test methods provided in BS EN 1254‑20 helps the user to inspect the quality of the fitting joints under various pressure and forces, allowing for an efficient and high-quality plumbing system.

As the buyer of BS EN 1254‑20, you can be ensured of durable, corrosion and heat-resistant plumbing fittings that minimize the risk of leakage and contamination. As a result, BS EN 1254-20 takes into account safety and protection of the product end-user while also prolonging the service-life of the fitting. Moreover, guidance regarding the right installation and appropriate parts and materials is essential in the success of plumbing fittings, in any given application. Overall, with BS EN 1254-20, you will be able to scale your business with globally accepted guidelines
