ISO 19097-2:2018规定了土壤或天然水中用于外加电流阴极保护的混合金属氧化物阳极的加速寿命试验方法。加速寿命试验结果可用于比较阳极的耐久性，并评估阳极在额定电流输出下是否符合设计预期寿命的要求。

ISO 19097-2:2018 specifies accelerated life test method of mixed metal oxide anodes for impressed current cathodic protection used in soil or natural waters. The accelerated life test results can be used to compare the durability of the anodes and to evaluate whether the anodes can comply with required specifications of design life expectancy at rated current output.
