ISO 4665-2016是關于硫化或熱塑性橡膠-耐候性測試方法。 本標準規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
