How to check the purging quality during target shooting purging
Thread Content
Target shooting standards: The size of the marks on the target sheet should be ≤φ0.6mm; the depth of the marks should be <0.5mm; the number of particles per cm2 should be <1. With such small impurity particles, how is quality controlled? How are the size, depth, and area of these impurity particles measured? What tools are used for that?
It is generally observed directly with the naked eye; P
This method of observation is a bit rough, haha;P
It’s all viewed with the eyes, but if the target isn’t cleaned properly and ends up covered in pits and imperfections, our targets are quite clean, without any obvious marks
This requires standard target plates, which must be installed at the firing outlet in accordance with specifications; the damage to these target plates is checked regularly, usually by manual inspection
Agree with what was said on floor 5: standard target plates are required, which should be installed at the shooting exit in accordance with relevant specifications. The damage to these target plates needs to be checked regularly, and usually the assessment is done through manual inspection
It is usually done through visual inspection; of course, the cleaner it is, the better, but costs must also be taken into account
If there is a turbine, aluminum plates are used as target sheets to test the purging effect. If there’s no turbine, just use a white cloth to check if it’s dirty
