請問ASTM有關銅腐蝕率的規範

請問ASTM中是否有關銅的腐蝕率的說明

例如: 在某個環境下銅的腐蝕率多少mil/per year算是標準

或是ASTM中哪個章節會提及有關的敘述

贈20點

    ASTM出版,COSTAS L. P.著作的

    Atmospheric corrosion of Copper alloys exposed for 15 to 20 years

    一書中有關於銅腐蝕的敘述。

    十三件銅合金置於兩處海上、一處工業區、一處郊區,經過 15 至 20 年,在工業區的腐蝕率平均約是 1.4 μm/year ,在其他地區的腐蝕率平均約是 0.7 μm/year。

    Résumé / Abstract

    Copper alloys were exposed for 15 to 20 years at two marine, one industrial, and one rural location. Based on average corrosion rates for 13 alloys, the industrial corrosion rate was 1.4 μm/year whereas the rate for the other sites was approximately 0.7 μm/year. As expected, alloying agents affected the corrosion rates by a factor of 2 to 3. General attack was the predominant form of corrosion. Dezincification was positively identified in C260 alloy and intergranular attack was noted in C642. Pitting was not a factor for any alloy.

    我剛翻了一下

    以我們做銅器五金的規範中ASTM並沒有詳述此測試

    你應該可參考下列規範

    DIN 50900 corrosion of metal

    ISO 6509 1981E

    裡面有詳細記載測試程序等相關內容
