The interior of the equipment is equipped with specialized testing fixtures, enabling multi-dimensional adjustment and precise positioning of the jetting point and sample position. It fully meets the requirements of ISO 16925 testing for parameters such as jetting angle and distance. The specific adjustment parameters are as follows:

- Adjustment of spray point: The travel range is 0-300mm, and manual adjustment is adopted, which is convenient to operate and allows precise control of the distance between the spray point and the sample.

- Left-right adjustment of sample testing platform: with a travel range of 0-800mm, it adopts servo adjustment mode, featuring high adjustment accuracy, enabling precise positioning of the sample's left-right position.

- Sample fixation method: The sample testing platform is equipped with 0-degree and 45-degree fixture plates, allowing for the selection of sample placement angles according to testing requirements and adapting to different testing scenarios.

- Up and down adjustment of spray point: The distance can be adjusted manually from 0 to 400mm, allowing for flexible adjustment of the height position of the spray point.

- Spray point angle adjustment: The adjustment range is 0-±90 degrees, using manual adjustment. It allows for steam spray testing at different angles, fully covering the testing angle range required by the standard.

- Pointing function: Equipped with an infrared pointing device, it can quickly and accurately locate the spray point, ensuring that the spray position perfectly corresponds to the test area of the sample, thereby enhancing test accuracy.

- Sample fixation: A rapid clamping method is employed to quickly secure the sample, enhancing testing efficiency while ensuring that the sample remains secure and does not shift during the testing process.
