            ISO 4665-2016是關(guān)于硫化或熱塑性橡膠-耐候性測試方法。 本標準規(guī)定了以熒光紫外燈和冷凝裝置模擬天然氣候的太陽紫外光、溫度和冷凝水等老化因素的一種人工氣候老化試驗方法。

            本標準適用于硫化橡膠在紫外光照和冷凝作用交替條件下暴露的耐候性試驗。*新標準ISO 4665-2016發(fā)布于2016年1月。

            ISO 4665-2016英文介紹

            ISO 4665:2016 specifies methods for the exposure of vulcanized or thermoplastic rubbers to natural or artificial weathering and methods for the determination of changes in colour, appearance, and physical properties resulting from exposure.

            1 Scope

            This International Standard specifies methods for the exposure of vulcanized or thermoplastic rubbers to natural or artificial weathering and methods for the determination of changes in colour, appearance, and physical properties resulting from exposure.

            3 Terms and definitions

             

            For the purposes of this document, the terms and definitions given in ISO 877 and ISO 4892 and the following apply.

            3.1control

            material exposed alongside the test material for comparison

            Note 1 to entry: The control, for example, may be a material of similar or related composition to the test material or a material having a known response to the exposure conditions.

            3.2file test piece

            portion of the material to be tested which is stored under conditions in which it is stable and is used for comparison between the exposed and the original state

            3.3masked area

            portion of the exposed test piece which is protected from light exposure by masking

            3.4weathering reference material

            reference material whose weathering degradation properties are well documented and repeatable when exposed to identical conditions

            3.5exposure stage

            interval of exposure between determinations of change in properties, expressed as time or radiant exposure
