DIN 50018-2013適用范圍

This standard mainly covers performance checks carried out on test arrangements used to assess anti-corrosion systems. Users of this standard are also requested to consult other relevant standards and regulations and are advised that individual test conditions may be also agreed upon on a case by case basis. As it cannot be ruled out that specimens, on which different anti-corrosion systems have been applied, may interact, it is recommended that different anti-corrosion systems be tested separately. If various anti-corrosion systems applied to different test materials are to be tested together, it should be taken into account that the sulfur dioxide tends to have diverse effects on the materials under test and that results are, therefore, not always reproducible. Unless the anti-corrosion systems compared are similar to one another, it may be difficult to draw reliable conclusions with regard to their effectiveness under service conditions. In the same way that corrosive test conditions differ considerably from those occurring in service, so do the levels of protection afforded by anti-corrosion systems.

本標(biāo)準(zhǔn)主要涵蓋對(duì)用于評(píng)估防腐系統(tǒng)的試驗(yàn)安排進(jìn)行的性能檢查。本標(biāo)準(zhǔn)的使用者還應(yīng)參考其他相關(guān)標(biāo)準(zhǔn)和法規(guī)，并建議根據(jù)具體情況商定單獨(dú)的試驗(yàn)條件。由于不能排除已應(yīng)用不同防腐系統(tǒng)的試樣可能相互作用，因此建議單獨(dú)測(cè)試不同的防腐系統(tǒng)。如果對(duì)不同試驗(yàn)材料使用的各種防腐系統(tǒng)要一起進(jìn)行試驗(yàn)，則應(yīng)考慮到二氧化硫往往對(duì)試驗(yàn)材料產(chǎn)生不同的影響，因此，結(jié)果并不總是可再現(xiàn)的。除非所比較的防腐系統(tǒng)彼此相似，否則可能難以就其在使用條件下的有效性得出可靠結(jié)論。腐蝕性試驗(yàn)條件與使用中的腐蝕性試驗(yàn)條件有很大不同，同樣，防腐系統(tǒng)提供的防護(hù)等級(jí)也有很大差異。
