Hi Mr.Lee,

If you search the client`s requirements, I am sure, you can find the specific test method/purpose/applicable standard no. Nevertheless if you can not find the detail instruction in the customer`s requirements, you have to ask the detail test method to them because there are a lot of test methods as follows in corrosion tests (* they are not full list but only a part).

용접부 또는 모재에 Corrosion test를 실시 하게 되어 있는데 어떻게 시험하는건지?
간단하지 않다면 전문 시험기관에 의뢰를 해야 하는건지....

----------------- [답 변] -------------------
질문이 너무 막연합니다.

부식시험의 목적부터 알려주시는 것이 좋을 듯 합니다.

부식시험은 표준 시험법을 찾아보시면 잘 나와 있습니다. 시험결과를 공인받으시려면 공인기관에 의뢰하여야 하구요..

염수분무시험, 분극시험, 응력부식시험, 침적시험 등 아주 여러가지가 있을 수 있기 때문에 목적에 따라서 선택하여 사용하여야 할 것입니다.

채홍 씀.
