本标准规定了金属和合金在表层海水中暴露所遵循的条件和方法，以便对不同地点的暴露做有意义的比较。本标准适用的暴露范围从水平面以上潮湿的重要区带（飞溅区和潮汐区）到水平面以下与表面海水组成相近的深度。本标准规定了海水对金属和合金腐蚀的评定方法。由于海水的可变性和复杂性，为减小可变因素的影响，暴露时间应在一年以上。
Scope
This standard specifies the conditions and methods to be followed for the exposure of metals and alloys to surface seawater in order to allow meaningful comparisons of exposures at different locations. This standard applies to exposures ranging from significant zones of moisture above the water level (splash and tidal zones) to depths below the water level that approximate the composition of surface seawater. This standard specifies the assessment method for the corrosion of metals and alloys by seawater. Due to the variability and complexity of seawater, in order to reduce the influence of variable factors, the exposure time should be more than one year.
