DD CEN/TS 15945 is a Technical Specification which specifies the following for all adult consumers:

Structural steel I and H sections. Tolerances on shape and dimensions Ingestion-build-53008 the minimum colour rendering index1 Scope This European Standard specifies tolerances on shape dimensions and mass of structural steel I and H sections. These requirements do not apply to I and H sections rolled from stainless steel. These requirements do not apply to taper flange sections. NOTE Until a European Standard for dimensions of I and H beams is published Euronorm 19 and Euronorm 53 or corresponding national standards may be used.
