本规范规定了水下湿保护金属电弧焊用焊条的分类要求。要求包括焊缝金属的机械性能、焊缝金属的坚固性和焊条的可用性。还包括对焊缝金属成分、标准尺寸和长度、标记、制造和包装的要求。本标准的使用指南包含在附录中。本规范使用美国惯用单位和国际单位制（SI）。由于这些系统并不等同，因此每个系统必须独立使用。

This specification establishes the requirements for classification of covered electrodes for underwater wet shielded metal arc welding. The requirements include mechanical properties of weld metal, weld metal soundness, and usability of electrode. Requirements for composition of the weld metal, standard sizes and lengths, marking, manufacturing, and packaging are also included. A guide to the use of the standard is included in an Annex. This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
