Flame Retardant Paper & Paperboard Flammability Tester: Proving Paper Stops Burning — BRT ZBY
Paper burns fast. Flame-retardant paper is supposed to stop — but how do you prove it?
From food packaging and decorative wall panels to industrial insulation paper, flame-retardant paper and paperboard sit in some of the most fire-sensitive corners of daily life. Yet paper is one of the hardest materials to make genuinely fire-safe: it ignites easily and, once burning, can spread a flame in seconds. That is why flame-retardant paper products — coated, printed or water-leached — must pass standardized flammability testing before they can be certified for use.
As a professional manufacturer of flammability testing instruments, Baoruitong Automation Equipment Co., Ltd. (BRT) presents the ZBY Flame Retardant Paper & Paperboard Combustion Tester, a dedicated vertical flammability test machine developed strictly per GB/T 14656-2009
What Does the Paper Flammability Test Measure?
Per GB/T 14656-2009 (Test method for burning behavior of flame-retardant paper and paperboard), a paper specimen is tested in a vertical position under a controlled flame, and the instrument precisely records the two core flammability indicators:
- Afterflame time — how long the specimen continues to burn after the ignition source is removed
- Afterglow time — how long the specimen continues to glow without a visible flame
These numbers provide standardized, reliable data that paper factories, packaging material manufacturers, fire safety inspection institutions and paper material R&D laboratories use to verify the flame-retardant qualification of paper products — including samples after water leaching treatment.

FAQ
What is a flame retardant paper tester? A flame retardant paper tester is a vertical flammability testing instrument that measures the burning behavior of flame-retardant paper and paperboard — primarily afterflame time and afterglow time — under a controlled flame, per standards such as GB/T 14656-2009.
Which standard applies to paper flammability testing? GB/T 14656-2009 (Test method for burning behavior of flame-retardant paper and paperboard) is the core standard, supported by GB/T 5907.1 for fire safety terminology and GB/T 10739-2023 for standard atmosphere conditioning of paper and board.
Which paper materials can be tested? Flame-retardant paper, paperboard, coated, printed and water-leached paper materials with thickness ≤ 1.6 mm — covering packaging, decorative and industrial flame-retardant paper products.
How does the ZBY tester work? A 210 mm × 70 mm specimen is exposed to a fixed 12-second flame from a 0°–45° adjustable burner; the instrument’s ±0.01 s precision timing system automatically records afterflame and afterglow time up to 99 minutes 99 seconds.
Why is afterglow time important for paper? Paper can continue glowing without a visible flame after the flame is removed, which can reignite nearby materials. Measuring both afterflame and afterglow time gives a complete picture of a paper product’s fire risk.
