本规范涵盖液体浓缩物或水溶性粉末形式的碱性脱脂剂化合物，用于用水稀释。本产品通常用于在高温下浸泡在化合物溶液中，去除飞机涡轮发动机零件上的油、油脂或其他污垢，但使用不限于此类应用。这些化合物不适合清洁铝或镁零件。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 degreaser compound in the form of a liquid concentrate or a water-soluble powder for dilution with water.This product has been used typically for removing oils, greases, or other soils 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 or magnesium parts. Restrictions for cleaning titanium parts may be imposed by the engine manufacturer.
