        JASO M351-1998標準介紹

        1. Scope

        This standard specifies test procedures by xenon-arc lamp type weathering apparatus (here-after referred to as "apparatus") for evaluatingthe weatherability of various automotive materials and parts such as body paint, exterior partspaint, and plastics used for exterior equipment.

        Note: A xenon-arc lamp type weathering apparatusis an apparatus capable of irradiating artificial light similar to sunlight in order to investigate the degree of weatherability over ashort period of time.

        2. Normative References

        This standard contains references to the following standards, which by inclusion, constituteprovisions of this standard. Use the latest editionof these standards.

        JIS B 7754 Light-exposure and light-and-water exposure apparatus (Xenon-arc lamp type)

        JIS D 0205 Test method of weatherability forautomotive parts

        JIS L 0843 Testing method for colour fastness to xenon arc lamp light

        JIS Z 8722 Methods of colour measurement-reflecting or transmitting objects

        JIS Z 8730 Colour specification-colour differences of non-luminous materials

        JIS Z 8741 Specular glossiness-methods ofmeasurement

        3. Definitions

        Definitions of terms used in this standard follow.

        a) Weatherability

        Resistance to deterioration due mainly to exposure to sunlight, rain and snow, or atmospheric temperature and humidity in a naturalenvironment.

        b) Black panel temperature (hereinafterreferred to as "B.P.T")

        Temperature which represents the surfacetemperature of a specimen and indicated by a black panel temperature meter attached toa rack or turn table.

        c) Xenon-arc lamp

        Quartz jacketed xenon-arc lamps, by xenon-arc discharge, emit radiation in a range thatextends from below 270nm in the ultravioletthrough the visible spectrum and into the infrared.

        d) Light emitter

        Part comprising a xenon-arc lamp and filter

        e) Exposing stage

        Final exposing stage where a specimenevaluation test is performed.
