Helmet UV Pretreatment Box Tester
The Helmet UV Pretreatment Box is designed to simulate ultraviolet (UV) exposure on safety helmets, replicating natural sunlight aging effects to evaluate long-term durability and safety performance. It provides a controlled and standardized environment for UV irradiation, ensuring that helmet materials undergo consistent preconditioning before subsequent testing. The equipment is widely used in helmet manufacturing quality control, safety compliance verification, and research laboratories.
Application
This tester has a broad range of applications in both laboratory testing and industrial quality assurance, including:
(1) Helmet Manufacturing: Pretreatment of industrial safety helmets, mining helmets, construction helmets, high-voltage insulating helmets, firefighting helmets, and arc flash helmets to simulate sunlight exposure before durability and performance tests.
(2) Material Research & Development: Testing engineering plastics, thermoplastics, and polymer composites used in helmet shells, visors, and internal supports for UV resistance and long-term stability.
(3) Laboratory Testing: Used in occupational safety and health labs, third-party testing institutions, and product certification labs to ensure compliance with national and international UV exposure standards.
(4) Special Applications: Pretreatment of sports helmets, cycling helmets, climbing helmets, or protective headgear in industries where UV exposure may affect material properties.
(5) Durability & Aging Studies: Enables simulation of long-term sunlight exposure to evaluate color stability, mechanical properties, and material degradation.
Specific products tested include:
Construction safety helmets
Firefighting helmets
High-voltage insulating helmets
Mining helmets
Engineering plastic helmet shells and visors
Arc flash protective helmets
