What are the quality requirements for plastic safety helmets?

Every safety helmet must be equipped with a valid manufacturer's safety production license, product certification, and safety appraisal certificate. If these documents are missing, the helmet must not be purchased, issued, or used. To ensure continued safety and effectiveness, each helmet should undergo annual inspection and testing to meet the national quality standards. These standards include:

• Visual Inspection: The helmet should have a smooth and complete surface without cracks or damage.
• Internal Components: The cap buffer band and headband must remain intact and functional.
• Heat Resistance: It should withstand temperatures between 40°C and 120°C without deforming.
• Chemical Resistance: The helmet should show good resistance to water, oil, and common chemicals.
• Impact Test: It must be able to withstand the impact of a 3kg steel ball dropped from a height of 5 meters.
