ISO 17248:2015规定了金属材料的高温腐蚀试验方法，方法是将金属材料嵌入由盐、灰和/或其他固体组成的腐蚀性粉末中，并将其暴露在受控气体环境中的高温下，以评估其耐腐蚀性。 有两种选择:完全嵌入和部分嵌入。 在需要进行质量变化测量的情况下，使用完全嵌入。 部分嵌入用于研究单个试件上三个可能不同的相互作用区域，即嵌入件、非嵌入件和气体/粉末界面区域。因此，重量测量不合适，需要进行金相调查。 ISO 17248:2015不包括将试样浸入液体中的方法，或在试样上施加表面沉积物的情况。 这些方法分别包含在ISO 17245和ISO 17224中。

ISO 17248:2015 specifies the method for high temperature corrosion testing of metallic materials by embedding in a corrosive powder made up of salt, ash, and/or other solids and exposing them to high temperature in a controlled gas environment to evaluate their corrosion resistance. Two options exist: fully embedding and partially embedding. Fully embedding is used in cases in which a mass change measurement is required. Partially embedding is used to investigate three potentially different interaction zones on a single test piece, i.e. the embedded part, the non-embedded part, and the gas/powder interface region. Therefore, gravimetric measurements are not appropriate and metallographic investigations are necessary instead. ISO 17248:2015 does not cover methods where test pieces are immersed in a liquid or cases in which a surface deposit is applied to the test pieces. These methods are covered in ISO 17245 and ISO 17224, respectively.
