Visual inspection of appearance.
6. 2 Retractability test
GA/T 429—2003
Let the sample hang naturally and fix the handle. Hang a 10kg weight at the end of the sample and keep it relatively still. Release the weight instantly to make it free fall and observe whether the sample is fully unfolded; fully unfold the sample and hold the handle at the bottom. Hang a 20kg magnetic weight 1m above the sample and keep it relatively still. Release the weight instantly to make it free fall and observe whether the sample is fully retracted. 6.3 Expanded length inspectionwwW.bzxz.Net
Measure with a ruler.
6.4 Corrosion resistance
6.4.1 Metal telescopic baton
6.4.1.1 Use the neutral salt spray test (NSS) method for corrosion resistance test. 6.4.1.2 The temperature in the box is 35℃±2℃ and the humidity is greater than 95%. 6.4.1.3 Dissolve 50g ± 5g of chemically pure sodium chloride in 1L of distilled water. 6.4.1.4 The pH value of the solution can be adjusted to a range of 6 to 7 with chemically pure hydrochloric acid or sodium hydroxide and measured with a pH meter. 6.4.1.5 When the temperature in the chamber reaches the test temperature, place a sample. Continuous spraying shall not be interrupted within the specified period. 6.4.1.6 After the test, remove the sample from the salt spray chamber and gently rinse it with running cold water (below 35°C) or use a sponge to remove surface salt deposits; then immediately dry it at 80°C to 100°C for 30 minutes, and check the degree of corrosion in time. 6.4.2 Non-metallic telescopic baton
Use distilled water to prepare a 3% (mass) sodium chloride solution. After immersing the sample in a sodium chloride aqueous solution at a temperature of 25°C ± 1°C for 72 hours, take out the sample, wash off the salt traces with tap water, and observe the changes in the paint film. 6.5 Tensile strength test
Fully unfold the sample, fix it horizontally on the test seat, fix the tension traction head at the two ends of the sample, and use a tensile testing machine to test.
6.6 Deformation test
6.6.1 Deformation test of rigid baton
Fully unfold the sample, fix the handle horizontally, hang a 10kg weight at 10mm from the front end, test for 2 minutes, remove the weight, measure the deformation and check the elasticity of the sample. 6.6.2 Deformation test of elastic baton
Fully unfold the sample, fix the handle horizontally, bend the front end backward 180°, repeat 100 times, measure the deformation and check the elasticity of the sample.
6.7 Service life test
Fix the sample to be tested on a special impact resistance life test bench for simulation test. The impacted surface is parallel to the 5cm thick rubber pad. The impact part is located at the first node of the front end (except the end cap). Each time the impact is made, the linear speed is 5m/s±0.5m/s. When it reaches 1000 times, the sample is tested for elasticity and the deformation of the thinnest part is measured. 7 Inspection rules

Type inspection
If other individual performance indicators are unqualified, double sampling and re-inspection are allowed. If the double re-inspection is qualified, the batch of products is determined to be qualified, d)
Otherwise, it will be treated as an unqualified batch.
8 Marking, packaging, transportation and storage
