This Standard specifies methods for exposing specimens to open-flame carbon-arc
lamps in presence of moisture to reproduce the weathering effects that occur when ma-
terials are exposed in actual end-use environments in daylight or daylight filtered
through window glass.
Specimen preparation and evaluation of the results are covered in other JIS stan-
dards for specific materials.
General guidance related to the test is given in JIS K 7350-1.
NOTE: The International Standard corresponding to this Standard and the sym-
bol of degree of correspondence are as follows.
ISO 4892-4:2004 Plastics--Methods of exposure to laboratory light
sources--Part 4: Open-flame carbon-arc lamps and Technical Corrigen-
dum i (2005) (MOD)
The symbols which denote the degree of correspondence in the con-
tents between JIS and the corresponding International Standard are IDT
(identical), MOD (modified) and NEQ (not equivalent) according to ISO/
IEC Guide 21.
