本规范涵盖了一种碱性除锈剂化合物，其形式为浓缩液或水溶性粉末，可用水稀释。本产品通常用于在高温下浸入化合物溶液中，去除飞机涡轮发动机零件上的锈迹，但使用不限于此类应用。这些化合物不适合清洁铝零件。发动机制造商可能会对钛部件的清洁施加限制。

This specification covers an alkaline rust remover compound in the form of a liquid concentrate or water-soluble powder for dilution with water. This product has been used typically for removing rust from aircraft turbine engine parts by immersion in a solution of the compound at elevated temperature, but usage is not limited to such applications. These compounds are unsuitable for cleaning aluminum parts. Restrictions for cleaning titanium parts may be imposed by the engine manufacturer.
