Shenyang Baoruitong Launches New ZBY Combustion Tester for Flame-Retardant Paper and Paperboard Testing

News Release — Shenyang, China — Shenyang Baoruitong Automation Equipment Co., Ltd., a professional manufacturer of flammability testing equipment and laboratory test instruments, today announced the release of its new ZBY Combustion Tester for Flame-Retardant Paper and Paperboard. The instrument delivers accurate, repeatable paper flammability testing for manufacturers, testing laboratories and quality control departments that must verify the fire-retardant performance of paper and paperboard products in compliance with GB/T 14656-2009.

Precision Paper Flammability Testing in One Compact Instrument

The ZBY paper combustion tester is purpose-built to evaluate the burning behavior of flame-retardant-treated and water-leached paper and paperboard with a thickness not exceeding 1.6 mm, as well as coated or printed flame-retardant paper products below 1.6 mm. From fire-resistant packaging and wallpaper to electrical insulation paper and flame-retardant labels, this paper burn test equipment provides the objective, standards-based data manufacturers need to prove product safety and market compliance.

Full Compliance with Paper Testing Standards

Designed in accordance with the Chinese national standard GB/T 14656-2009 (Test method for burning behavior of flame-retardant paper and paperboard), the tester also conforms to GB/T 5907.1 (fire protection terminology) and GB/T 10739-2023 (paper, board and pulp — standard atmosphere for conditioning and testing), ensuring a complete, traceable testing workflow from specimen conditioning to final classification.

Key Selling Points: Accuracy, Automation and Ease of Use

Automatic Timing with Digital Readout

single-chip microcomputer control system provides automatic timing with digital display of test results. The flame-application time to the specimen is fixed at 12 s with ±0.01 s accuracy, while afterflame and afterglow time can be measured up to 0–99 min 99 s and displayed digitally — eliminating manual stopwatch error and improving the repeatability of every paper fire test.

Precision Flame Control with Adjustable Bunsen Burner

The tester features a Bunsen burner with a 10 mm ± 0.2 mm inner diameter, tiltable from 0° to 45° in eight 5° steps for flexible specimen exposure. The blue-flame height is freely adjustable from 15 mm to 175 mm, with a built-in flame-height ruler for fast, accurate setup. The automatic ignition time is freely settable, giving operators full control over the test procedure.

Designed for Real-World Flame-Retardant Paper Testing

The instrument accepts standard 210 mm × 70 mm paper specimens and is suitable for a wide range of samples, including:

  • Flame-retardant-treated paper and paperboard
  • Water-leached fire-retardant paper products
  • Coated or printed flame-retardant paper (thickness < 1.6 mm)
  • Decorative fireproof paper, electrical insulating paper and flame-retardant packaging

Compact, Safe and Economical Operation

Operating on 220 V ± 10%, 50 Hz with power consumption under 100 W, the ZBY tester is energy-efficient and easy to install in any testing laboratory. It runs on liquefied propane (purity ≥ 95%), a widely available and cost-effective gas source. With compact overall dimensions of approximately 670 mm × 300 mm × 800 mm and a weight of only ~40 kg, it fits seamlessly into crowded QC labs, research centers and third-party testing institutions.

Applications Across the Paper Industry

The ZBY flame-retardant paper and paperboard combustion tester is widely used for:

  • Fire-retardant paper manufacturing — routine quality control of flame-retardant-treated paper products
  • Paperboard packaging — verification of fire-retardant performance for flame-retardant carton and corrugated board applications
  • Wallpaper and decorative materials — burning behavior testing of coated and printed fireproof wallpaper
  • Electrical insulation paper — fire safety evaluation of insulating and transformer paper
  • Construction and interior materials — flame-retardant paper testing for building and decoration compliance
  • Third-party testing laboratories — standard-compliant paper flammability testing per GB/T 14656-2009
