BS EN 14901-2:2019

What is BS EN 14901‑2- Thermoplastic acid-modified polyolefin coating about?  

BS EN 14901 is a series of European standards on ductile iron pipes, fittings, and accessories that discusses the best procedures and specifications required for thermoplastic acid-modified polyolefin coating of ductile iron fittings and accessories. BS EN 14901‑2 is the second part of a series of documents on ductile iron pipes, fittings, and accessories.  

BS EN 14901-2 defines the requirements and test methods for factory-applied thermoplastic acid modified polyolefin (TMPO) coatings used for the protection of ductile iron fittings and accessories according to EN 545, EN 598:2007+A1:2009, EN 969, EN 12842, and EN 14525: 

• Conveying water (e.g. Potable water, raw water, …) at operating temperature up to 50 °c 
• Conveying wastewater at operating temperature up to 45 °c 
• Conveying gas at operating temperature up to 50 °c 
• Suitable for external environments, i.e. Soils, waters, and atmospheres of all common corrosion loads, characterized in D.2.3 of EN 545:2010 

Who is BS EN 14901‑2- Thermoplastic acid-modified polyolefin coating for?  

BS EN 14901‑2 on thermoplastic acid-modified polyolefin coating is relevant to: 

• Manufacturer of ductile iron pipes, fittings, and accessories  

Why should you use BS EN 14901‑2- Thermoplastic acid-modified polyolefin coating? 

A thermoplastic acid-modified polyolefin is a chemical substance that is composed of a high molecular weight polyethylene, rubber, and a reinforcing filler. This mixture contributes to the strong corrosion-resistant nature of thermoplastic olefins, which make them ideal for use in corrosion prevention. 

BS EN 14901‑2 navigates you through the surface preparation, cross-linkage, impact resistance, durability, chemical resistance, abrasion resistance, test methods of thermoplastic acid-modified polyolefin coating. 

As the user of BS EN 14901‑2, you would get appropriate guidance regarding the requirements and test methods of factory-applied thermoplastic acid-modified polyolefin coatings which assist you in protecting ductile iron pipes, fittings, and accessories from corrosion. As a result, BS EN 14901‑2 takes into account the safety and protection of the product while also prolonging the service life of the fitting.
