CEN/TC 266 - Thermoplastic static tanks

This European Standard specifies the requirements for materials (thermoplastics or steel), physical properties and performance of secondary containments used with specific thermoplastics static tanks complying with EN 13341.
This document is designed to be read with EN 13341.

Revision of EN 13341:2005 as far as:
- the resistance to weathering;
- the pressure resistance test;
- production of the specimen,
- factory production control;
- the lower limit of capacity
are concerned.

This document specifies requirements for above ground single static thermoplastic tanks of volume 450 l to 10 000 l, which can be used for the storage of liquids other than water including chemicals classified as dangerous goods.
This document only applies to tanks manufactured by blow moulding or rotational moulding of polyethylene, with or without reinforcements, which are not subjected to pressures exceeding ± 5 kPa (± 0,05 bar). Except for periodic temperature fluctuation their normal operating temperature does not exceed 25 °C.
This document only applies to tanks with a maximum lifetime of 10 years.
This document specifies permitted materials, performance requirements and test methods and factory production control tests.
This document does not consider wind and snow loads.
NOTE   National and/or International regulations above and beyond the requirements of this standard may apply to the storage of liquids and the installation of tanks.

This document specifies requirements for materials, physical properties and performance of single blow moulded and rotationally moulded polyethylene tanks or polyamide 6 (by anionic polymerisation) tanks, with or without reinforcements, for above ground storage of domestic heating oil, kerosene and diesel fuels.
It is only applicable to static blow moulded and rotationally moulded polyethylene tanks and polyamide 6 (by anionic polymerisation) tanks that are subject to atmospheric pressure and have a capacity from 450 l up to 10 000 l.
This document does not consider the consequences of wind or snow loading which is considered to be an installation issue.
