A Technical Specification (TS) is a normative document made available by CENELEC in at least one of the three official languages. A TS is established and approved by a technical body by a weighted vote of CENELEC national members. The Technical Specification is announced and made available at national level, but conflicting national standards may continue to exist. A Technical Specification is not permitted to conflict with an EN or HD. A TS is reviewed every 3 years at the latest. The maximum lifetime of a TS is 6 years.
Technical Specifications are established with a view to serving, for instance, the purpose of:
- publishing aspects of a subject which may support the development and progress of the European market,
- giving guidance to the market on or by specifications and related test methods,
- providing specifications in experimental circumstances and/or evolving technologies.
TSs are not amended but replaced by a new edition with a new date of edition. However, Corrigenda are possible.
