What is BS EN 1254‑7 about?

BS EN 12547 is the seventh part of the EN 1254 multi-series. BS EN 1254‑7 specifies product characteristics, assessment methods, compliance criteria of test results and a designation system for press fittings including their elastomeric seals, for connecting with metallic tubes. The fitting ends have a nominal diameter from 6 mm to 108 mm. The press fittings are designed for a service life of up to fifty years.

BS EN 1254‑7 is applicable to press fittings for joining one or more of the following tubes:

Copper tubes to EN 1057
Stainless steel tubes to EN 10312

With wall thicknesses and tempers as specified by the manufacturer

Products covered by BS EN 1254‑7 are intended to be used in:

Liquid applications
Gas applications

Who is BS EN 1254‑7 for?

BS EN 1254‑7 on press-fit fittings for use with metallic tubes is beneficial for:

Manufacturer of copper alloy press-fit fittings
Suppliers of parts and materials required for brazing of press-fit fittings
Installers
Quality assessment personnel
Civil and mechanical engineers
Trained and skilled technicians

Why should you use BS EN 1254‑7?

Unlike traditional brazing methods, press-fit involves no heat and no need to weld or solder joints and connections, thereby posing as a faster and low-cost alternative for the plumbing industry.

BS EN 1254‑7 provides information on product characteristics like internal pressure, tightness, the release of dangerous substances, the wall thickness at threaded portions of adaptor fittings, the durability of resistance to stress corrosion and high temperature, alignment of the fitting ends, shapes for tightening systems, surface condition, testing and sampling methods. Taking these factors into consideration, allow for an efficient and high-quality plumbing system.

As the buyer of BS EN 1254‑7, you can be ensured of durable press-fit fittings that minimize the risk of leakage and contamination. As a result, BS EN 1254-7 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 is essential in the success of press-fit fittings for use with metallic tubes. Overall, with BS EN 1254-7, you will be able to scale your business with these globally accepted guidelines
