In the requirements of the salt spray standard, it is mentioned that the angle of the test surface of the salt spray test specimen should reach 15° to 30° from the vertical direction, and as much as possible 20°. For irregular specimens (like the whole workpiece), it is also It should meet the above requirements as much as possible; Specimen needs to be hung on the bracket, its non-metallic materials such as cotton fiber, rayon or other insulating materials must be used as the material to hang the specimen Metal materials is strictly prohibited.
