The vertical and horizontal flame test is a common method for testing the combustion performance of materials, which can be used to evaluate the combustion characteristics of various materials. The following are some of the material types that require vertical and horizontal flame testing:

1. Building materials: Building materials, such as walls, floors, ceilings, insulation materials, thermal insulation materials, and roofing materials, etc., need to undergo vertical and horizontal flame tests to ensure their responsiveness and safety in fire or other thermal events .

2. Furniture and decoration materials: furniture and decoration materials, such as sofas, mattresses, curtains, carpets, wallpapers and decorative panels, etc., need to undergo vertical and horizontal flame tests to ensure their ability to respond to fires or other thermal events and safety.

3. Electrical equipment: Electrical equipment and electronic products, such as sockets, switches, wires, cables, and electronic equipment, etc., need to undergo vertical and horizontal flame tests to ensure their responsiveness and safety in fire or other thermal events.

4. Automotive interior: Automotive interior materials, such as seats, carpets, roof linings, dashboards, and door trims, require vertical and horizontal flame tests to ensure their response in fire or other thermal events capacity and safety.

In summary, the vertical and horizontal flame test is an important test method for evaluating the combustion performance of materials and is applicable to various material types to ensure their responsiveness and safety in the event of fire or other thermal events. Before the test, it is necessary to ensure that the test procedures and parameters stipulated in the standard are followed to ensure the accuracy and reliability of the test results.
