I'm afraid you are not going to like this, but they are either trying to sell old stock of doors or don't keep up with the times:
EN 13501-2-2004 - Fire classification of construction products and building elements - Part 2: Classification based on results of fire tests except for products for use in ventilation
Status: WITHDRAWN, so shouldn't be in use.
BS EN 81-58:2003. Safety rules for the construction and installation of lifts. Examination and tests
Status: Yes it includes Fire Resistance Tests, but for Lift Doors only!
And the UNE is the old Spanish Standard that has been superseded by Euro Norms - a check of Spanish guidance states that it is now unlawful to use doors to this standard unless they have also been tested to EN 1634-1 and CE marked.
