The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Subcommittee (SC) in CEN operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
The Standard specifies the requirements for shop fabricated cylindrical, horizontal tanks, single and double skin for underground storage of water polluting liquids (both flammable and non-flammable). The standard is applicable for normal operating conditions (-20°C to +50°C). Where temperatures can fall below this range, additional requirements shall be taken into account. Quittance on liquid material combinations is given in annex B. The standard is not applicable for liquids causing special danger. The standard does not deal with internal coating.
