natural durability test

基本解釋

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驗技術(shù)主要有自然環(huán)境試驗、自然環(huán)境加速試驗和實驗室加速試驗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(huán)境試驗考核涂層材料的耐候性，則試驗周期太長，在很多時候不能很好滿足設(shè)備在短期內(nèi)完成設(shè)計、試驗、定型的要求。
