Key technical requirements

4.2 Style specifications

The standard stipulates that the peaked brim hat must comply with the overall dress requirements of the police uniform, and the curvature of the brim should be controlled within the range of 115°±2° to ensure the visual uniformity of the guard of honor.

4.5 Material Standards

The main fabric is combed wool polyester serge as specified in GA 2111, and the auxiliary materials must meet the following requirements:

• Appendix A Feather yarndensity ≥200 strands/10cm
• Appendix F PVC synthetic cap leatherthickness 1.2±0.1mm

---

Implementation Key Points

Production Process Control

Special attention should be paid to the cutting process:

1. The deviation of the top piece of the hat is ≤1.5mm
2. The stitch density at the seam of the hat wall is 12±1 stitches/3cm

Key Points of Quality Inspection

According to Clause 6.3, fatal defects include:

• The corrosion resistance of metal parts does not meet the requirements of QB/T 3826
• The formaldehyde content exceeds the limit of GB/T 2912.1
