What Is a Paper and Paperboard Combustion Tester?

A paper and paperboard combustion tester is laboratory equipment used to assess how paper-based materials respond to a controlled ignition source. Depending on the selected test method, the instrument can help users observe and record ignition behavior, flame development, afterflame time, afterglow time, and related burning characteristics.

The ZBY Flame-Retardant Paper & Paperboard Combustion Tester is suitable for testing paper, paperboard, packaging materials, flame-retardant paper, coated paper, cellulose-based products, and other paper-related materials when the sample and method meet the requirements of the applicable standard.

Key Product Features and Selling Points

1. Automatic Timing with Digital Display

The ZBY combustion tester includes an automatic timing system and digital display for accurate recording of flame application and burning events. The image identifies a 12-second flame application time with timing accuracy of ±0.01 seconds.

Accurate timing helps laboratories improve repeatability when comparing:

• Flame-retardant paper formulations
• Paperboard grades
• Packaging materials
• Coated and laminated paper products
• Production batches
• Fire-retardant treatment performance

Automatic timing also reduces the variation that may occur when operators start and stop a test manually.

2. Adjustable Flame Height from 15 to 175 mm

Different paper products may require different flame conditions during evaluation. The ZBY tester provides an adjustable flame-height range of 15–175 mm, allowing operators to set the flame according to the selected procedure and test requirement.

Adjustable flame control is useful for:

• Comparative flammability testing
• Flame-retardant material development
• Research on paper ignition behavior
• Quality control of paper products
• Testing different thicknesses and material structures

The flame setting should always be selected according to the current applicable standard and validated laboratory method.

3. Controlled Burner Tilt from 0° to 45°

The burner can be adjusted through a 0–45° inclination range. This controlled burner angle supports flexible test configuration and allows laboratories to reproduce the specified flame orientation required for different paper and paperboard combustion methods.

Controlled burner inclination helps improve test consistency by maintaining a defined relationship between the flame, burner, and specimen. This is especially valuable when evaluating samples with different surface textures, densities, coatings, or orientations.

4. Afterflame and Afterglow Display

The ZBY tester provides an afterflame and afterglow display, allowing operators to observe the material after the ignition flame is removed.

• Afterflame refers to continued flaming after the ignition source is removed.
• Afterglow refers to continued glowing or smoldering after visible flaming has stopped.

These observations are important when evaluating flame-retardant paper, packaging paper, coated paperboard, and other cellulose-based products. A material that stops flaming quickly may still produce afterglow, so both behaviors should be recorded when required by the test method.

5. Enclosed Test Chamber for Controlled Observation

The ZBY combustion tester features an enclosed test chamber with a viewing window. The enclosure provides a defined test area and allows the operator to observe the specimen during ignition, flame development, afterflame, and afterglow stages.

A controlled chamber can help reduce the influence of accidental drafts and improve observation safety. As with all combustion equipment, suitable laboratory ventilation and fire-safety procedures should be implemented before operation.

Applicable Standards Shown for the ZBY Tester

The product image identifies the following standards and technical references:

• GB/T 14656-2009
• GB/T 5907.1
• GB/T 10739-2023

The exact specimen dimensions, conditioning procedure, burner settings, ignition time, evaluation criteria, and reporting format should be confirmed against the current edition of the applicable standard before testing or certification.

Applications of the ZBY Paper Combustion Tester

Flame-Retardant Paper Development

Paper manufacturers can use the ZBY tester to compare flame-retardant treatments, additives, coating systems, and cellulose formulations. The equipment supports development work by showing how formulation changes affect ignition, flame persistence, and afterglow.

Paperboard and Packaging Quality Control

Packaging manufacturers can use combustion testing to evaluate paperboard, cartons, corrugated materials, and other paper-based packaging products. Test data can support incoming material inspection, production monitoring, and batch comparison.

Printing and Coated Paper Evaluation

Inks, coatings, laminates, and surface treatments can change the burning behavior of paper products. The ZBY tester can help laboratories compare coated and uncoated samples and assess how surface treatments influence flame response.

Research and Development Laboratories

Universities, testing institutions, and industrial R&D laboratories can use the tester for paper flammability research, combustion behavior studies, flame-retardant technology development, and method comparison.

Quality Assurance and Compliance Support

The instrument can support documentation for internal quality programs and standard-oriented testing. It provides controlled operating parameters and digital timing information for more traceable laboratory records.
