What is BS EN 13121-3 - GRP tanks and vessels for use above ground about?
BS EN 13121 discusses GRP tanks and vessels for use above ground.
BS EN 13121-3 is the third part of BS EN 13121 multi-series and discusses design and workmanship. BS EN 13121-3 gives requirements for the design, fabrication, inspection, testing and verification of GRP tanks and vessels with or without thermoplastics lining for storage or processing of fluids, factory-made or site built, non-pressurized or pressurized up to 10 bar, for use above ground.
The terms vessels and tanks as used in BS EN 13121-3 include branches up to the point of connection to pipework or other equipment by bolting and supports, brackets or other attachments bonded directly to the shell. BS EN 13121-3 covers vessels and tanks subject to temperatures between – 40 °C and 120 °C.
Who is BS EN 13121-3 - GRP tanks and vessels for use above ground for?
BS EN 13121-3 on GRP tanks and vessels for use above ground is useful for:
- Tanks and vessels manufacturers
- Design engineers
- Quality control personnel
- Testing Laboratories
Why should you use BS EN 13121-3 - GRP tanks and vessels for use above ground?
Metallic vessels, and those manufactured from other isotropic, homogeneous materials, are conveniently designed by calculating permissible loads based on measured tensile and ductility properties.
GRP, on the other hand, is a laminar material, manufactured through the successive application of individual layers of reinforcement. As a result, there are many possible combinations of reinforcement types that will meet the structural requirement of an anyone-design case. This allows the designer to select the laminate construction best suited to the available manufacturing facilities and hence be most cost-effective. The design and manufacture of GRP tanks and vessels involve several different materials such as resins, thermoplastics and reinforcing fibres and several different manufacturing methods. It is implicit that vessels and tanks covered by BS EN 13121-3 are made only by manufacturers who are competent and suitably equipped to comply with all the requirements of BS EN 13121-3, using materials manufactured by competent and experienced material manufacturers.
BS EN 13121-3 provides you with the mechanical, thermal and design properties of GRP tanks and vessels. BS EN 13121-3 helps you to design and manufacture high-quality GRP tanks and vessels.
What’s changed since the last update?
BS EN 13121-3:2016 supersedes BS 4994:1987 and BS EN 13121-3:2008+A1:2010 which are withdrawn. It includes some technical changes. These include:
- The standard was totally revised to make it comply with EN 1990
- Sections covering "Flat panels" and "Loading from local loads" removed from the standard
