This Standard specifies methods for exposing specimens to fluorescent UV radia-
tion, heat and water in apparatus designed to reproduce the weathering effects that
occur when materials are exposed in actual end-use environments to daylight, or to
daylight through window glass.
The specimens are exposed to fluorescent UV lamps under controlled environmen-
tal conditions (temperature, humidity and/or water). Specimen preparation and evalu-
ation of the results are covered in relevant standards for specific materials.
General guidance is given in JIS K 7350-1.
NOTE 1 Fluorescent UV lamp exposures for paints, varnishes and other coat-
ings are described in JIS K 5600-7-8.
NOTE 2 The International Standard corresponding to this Standard is as fol-
lows.
ISO 4892-3:2006 Plastics--Methods of exposure to laboratory light
sources Part 3: Fluorescent UV lamps (MOD)
In addition, symbols which denote the degree of correspondence in
the contents between the relevant International Standard and JIS are
IDT (identical), MOD (modified), and NEQ (not equivalent) according
to ISO/IEC Guide 21.
