Two of the tests prescribed aredefined in other International Standards: ISO9227and ISO 2409 Two additional tests, a water-condensation test and a dip test, are also prescribed and the procedure for carrying them out is described in annexes. This International Standard also specifies the minimum requirements regarding reflectance as well as The quality of a silvered mirror can be affected by faults that alter the appearance of the image of reflected reflective coating.

This International Standard applies only to mirrors from silvered glass manufactured from flat, annealed clear to which no further processing (such as edgework or other fabrication) has been done NOTE 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. This specification covers the quality requirements of silvered, annealed, monolithic, clear and tinted flat glass mirrors. Mirrors covered in this specification are not intended for use in environments, e.g. horse-riding halls, swimming pools,medical baths,saunas, swimmi
