natural durability test

基本解释

Currently, 3 test methods, including the natural environmental testing, the natural accelerated testing and the laboratory accelerated testing, are used to evaluate materials durability.
目前，評價材料耐候性的試騐技術主要有自然環境試騐、自然環境加速試騐和實騐室加速試騐3種方法。
The test cycle is too long if the natural environment is used to evaluate materials durability. The evaluation test can not meet the requirements of design, testing, setting in short term very well.
若通過自然環境試騐考核塗層材料的耐候性，則試騐周期太長，在很多時候不能很好滿足設備在短期內完成設計、試騐、定型的要求。
