T/YJC 023-2024 Reusable Material Car Light Housing

Scope

Main technical content: It is suitable for the shells of vehicle lamps such as cars and motorcycles, and is made from renewable materials such as bio-based materials and recycled plastics. Firstly, it clarifies that renewable materials are natural or artificially cultivated materials that can be regenerated within a certain period of time. Terms such as "vehicle lamp shells" are defined as the outer casings used to protect and fix vehicle lamp components, and they are classified according to material types and lamp types. In terms of requirements, the appearance should be smooth and free from scratches or cracks, and the color and logos should meet standards. The dimensional accuracy should meet design and installation requirements. The mechanical properties of tensile strength, bending strength, and impact strength all have minimum indicators. The thermal properties include specifications for Vicat softening temperature, heat deformation temperature, and thermal aging performance. The weather resistance performance covers requirements under light aging, wet-heat, and salt spray tests. The flame retardancy performance should meet standard grades. Environmental requirements include no harmful substances in the materials and compliance with discharge of three wastes during the production process. Correspondingly, the testing methods include visual observation under specific light sources and colorimeter measurement for appearance, dimensional accuracy detection using specific measuring tools, and testing and inspection of mechanical properties, thermal performance, weather resistance performance, flame retardancy performance, and environmental performance according to the procedures and methods specified in relevant national standards, so as to ensure the quality and performance of renewable material vehicle lamp shells and promote the green development of the industry.
