Glass in building — Silvered, flat-glass mirror
ISO 25537:2008 specifies the minimum quality requirements (regarding optical, visual and edge faults) and durability tests for silvered float glass for internal use in buildings. ISO 25537:2008 applies only to mirrors from silvered glass manufactured from flat, annealed clear or tinted float glass, from 2 mm to 6 mm thick, and supplied in stock/standard sizes and as-cut finished sizes to which no further processing (such as edgework or other fabrication) has been done. Upon consultation with the mirror manufacturer, it is possible to apply this International Standard to float glass having a thickness less than 2 mm or greater than 6 mm. ISO 25537:2008 covers the quality requirements of silvered, annealed, monolithic, clear and tinted flat glass mirrors. Mirrors covered in ISO 25537:2008 are not intended for use in environments, e.g. horse-riding halls, swimming pools, medical baths, saunas, swimming pool areas, chemical laboratories and other corrosive environments, where high humidity or airborne corrosion promoters, or both, are consistently present. This International Standard is not applicable to reflective glass for external glazing applications.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subje
