ISO 21010:2004规定了低温容器的气体/材料兼容性要求（如耐化学性），但不包括机械性能（例如低温应用）。 它给出了气体兼容性的一般指南，以及氧气和富氧大气的详细兼容性要求。 ISO 21010:2004还定义了确定低温容器和相关设备所用材料（金属和非金属）氧兼容性的试验方法。 它关注的是通常与低温流体接触或可能与低温流体接触的材料。

ISO 21010:2004 specifies gas/materials compatibility requirements (such as chemical resistance) for cryogenic vessels but it does not cover mechanical properties (e.g. for low temperature applications). It gives general guidance for compatibility with gases and detailed compatibility requirements for oxygen and oxygen-enriched atmospheres. ISO 21010:2004 also defines the testing methods for establishing oxygen compatibility of materials (metallic and non-metallic) to be used for cryogenic vessels and associated equipment. It focuses on materials that are normally with or could be in contact with cryogenic fluids.
