Standards:

GB/T 14656-2009：Test method for burning behavior of flame-retardant paper and board

Applications:

Firefighting industry: Used to evaluate and test the combustion performance of fire-resistant paper and cardboard to ensure their safety in case of fire.

Construction industry: Used to evaluate the combustion performance of building materials to ensure their safety in building structures.

Environmental protection industry: Used to evaluate and test the combustion performance of environmentally friendly materials to ensure their safety in the environment.

Laboratory research: Used in laboratory research and development to develop safer materials and products. The use of these testing instruments helps improve product safety, reduce fire risks, and protect human health and the environment.

Product Information:

The flame-retardant paper and cardboard combustion tester is suitable for testing the combustion performance of flame-retardant and water-washed paper and cardboard with a thickness of no more than 1.6 mm. It is also suitable for flame-retardant paper products with a thickness of less than 1.6 mm that have been coated or printed.

Feature

The testing instrument consists of a testing section and a control section, adopting an integrated design for convenient on-site installation and debugging.

A large observation window facilitates observation of the sample's combustion state.

Advanced industrial design and control features allow for easy access to the sample and burner.

Imported pressure gauges and pressure regulating valves accurately control the gas pressure in the pipeline.

Imported needle valves, combined with a gas mass flow meter, accurately control the gas flow rate.

An automatic timer records the test time.

The imported Bunsen burner has an inner diameter of 10mm ± 0.2mm; the flame application time is 12 seconds.

Pulse high-voltage electronic automatic ignition.

Equipment dimensions: Length × Width × Height (0.67 × 0.33 × 0.8) m.

Test Procedures

Sample preparation: Cut a sample of the standard size (e.g., 21cm × 7cm).

Sample fixing: Secure the sample vertically in the sample holder of the combustion chamber.

Flame adjustment: Use a Bunsen burner or other ignition device to adjust the flame length to the specified value (e.g., 4cm).

Ignition test: Ignite one end of the sample with the adjusted flame, and remove the flame after the specified time (e.g., 12 seconds).

Observation and recording: Measure the afterglow time and the length of charring on the paper strip. Shorter afterglow time and shorter charring length indicate better flame retardant paper.

Result determination: Determine whether the sample is qualified according to the standard (e.g., an average charring length < 11.5cm is considered acceptable).

Conclusion

The Flame Retardant Paper and Board Combustion Tester provides precise, repeatable assessment of paper and cardboard fire performance. It is essential for quality control, laboratory research, and ensuring compliance with fire safety standards.
