Needle flame tester is a device used to test the flame retardancy of materials, which simulates the dangerous scenario of small flames (such as match burning) to evaluate the flammability and flame spread risk of materials under specific conditions. Its main application industries include:
1、 Electronic and electrical industry
1. Application scenarios:
Detect the flame retardant level of electronic components (such as resistors, capacitors, connectors), circuit boards, sockets, switches, and other enclosures or insulation materials.
Evaluate the fire safety of internal components of household appliances (such as refrigerators, washing machines, air conditioners) and consumer electronics (such as mobile phones, laptops).
Standard basis: Complies with international/standards such as IEC 60695-2-2 and GB/T 5169.5, ensuring that the product has passed safety certification (such as CE, UL, CCC).
2、 Automotive and Parts Industry
1. Application scenarios:
Test the flame retardant performance of automotive interior materials (such as seat fabrics, dashboard plastics, door linings), wiring harness insulation layers, and engine compartment components.
Evaluate the fire rating of the battery pack casing and charging station components for new energy vehicles to meet safety requirements in the onboard environment.
Standard basis: Referring to automotive industry standards such as ISO 3795 and FMVSS 302, ensure the flame retardant reliability of materials under complex working conditions such as high temperature and vibration.
3、 Aerospace and Rail Transit
1. Application scenarios:
Detect the flame retardant properties of aircraft interior materials (such as seats, cabin wall panels) and high-speed rail car interiors (such as seats, roof panels) to prevent rapid spread of fire in enclosed spaces.
Evaluate the fire resistance performance of aircraft electronic equipment casings and components of rail transit signal systems.
Standard basis: Following strict standards such as ASTM E162 and EN 45545, the material is required to have multiple characteristics such as low smoke, halogen-free, and flame retardant.
4、 Construction and decoration industry
1. Application scenarios:
Test the flame retardant grade of building decoration materials (such as wallpaper, floor leather, curtain cloth), thermal insulation materials (such as XPS, EPS foam), and pipes (such as PVC trunking).
Evaluate the fire safety of furniture and soundproofing materials used in public places such as shopping malls and hotels, and ensure compliance with building fire safety regulations.
Standard basis: According to standards such as GB 8624 and ISO 1716, distinguish the combustion performance levels of materials (such as Class A non combustible and Class B1 flame retardant).
5、 Plastic and Polymer Materials Industry
1. Application scenarios:
Research and quality control of flame retardant properties for raw materials such as plastic pellets, films, and sheets, helping to optimize formulations (such as adding flame retardants).
Test the flame resistance of rubber products (such as cable sheaths and seals) to ensure that they meet industry standards.
Standard basis: Supports testing methods such as ISO 9772 (horizontal combustion) and ISO 9773 (vertical combustion) to provide data support for material selection.
