The SPCZ-05 Horizontal & Vertical Combustion Tester (UL94 Plastic Flammability Test Equipment) is a high-precision laboratory fire testing instrument engineered strictly in accordance with ANSI/UL 94, ISO 1210, GB/T 2408-2021, and IEC 60695-11-10 standards. It utilizes a standardized 50W Bunsen burner flame source (compliant with IEC 60695-11-4) to conduct both horizontal (HB) and vertical (V-0, V-1, V-2) burning tests on plastics, cellular materials, rubber, insulation components, and non-metallic electronic parts.
Driven by an intuitive PLC touchscreen control system, automated ignition tracking, motorized sample positioning, and an automatic gas shut-off safety interlock, this versatile Horizontal & Vertical Combustion Tester precisely measures afterflame time, afterglow time, and dripping ignition behavior. It is an indispensable tool for plastic raw material producers, consumer electronics manufacturers, automotive component suppliers, military inspection units, and certified third-party testing centers.

Technological Features of SPCZ-05 Horizontal & Vertical Combustion Tester
- Integrated PLC Touchscreen Control Architecture: Combines an industrial programmable logic controller (PLC) with a color touch interface for one-touch operation, real-time status monitoring, automatic timing recording, and parameter configuration.
- Full Motorized Sample Fixture & Precision Burner Retraction: Supports multi-axis motorized adjustment (forward, backward, upward, downward) controlled directly via the touchscreen. Upon completion of the programmed flame exposure duration, the 50W Bunsen burner automatically retracts.
- Switchable Auto-Ignition & Automatic Safety Gas Cut-Off: Features a switchable electronic auto-ignition system that can be toggled on or off to accommodate varied protocol steps. Includes an automatic gas shut-off valve to prevent gas buildup or fire hazards upon test termination.
- Automated Combustion Timing & Built-In Memory: Dedicated timing modules automatically capture flame application time, afterflame time (t1, t2), and afterglow duration without requiring manual stopwatches, eliminating operator reaction errors and saving batch data internally.
- Corrosion-Resistant Chamber with Internal Lighting & Ventilation: Constructed with a heavy-duty powder-coated cabinet and dark interior to facilitate clear observation of flame propagation and flaming drips. Equipped with internal LED lighting and an integrated smoke exhaust fan.

System Architecture & Testing Workflow of UL94 Flammability Tester
Standardized Testing Workflow:
- Mount the standard bar specimen (125mm × 13mm) vertically or horizontally into the motorized clamp over the surgical cotton indicator tray.
- Select the target test protocol (e.g., UL94 V-0/1/2 vertical test, HB horizontal test, or ISO 1210 method) on the PLC touchscreen.
- Adjust the 50W Bunsen burner flame to a 20mm blue inner cone using the fine-tuning needle valve.
- Initiate the test sequence; the burner automatically advances, applies the flame to the sample for the programmed duration (e.g., 10 seconds), and retracts.
- The system automatically records afterflame time (t1, t2), afterglow time, and dripping ignition, then outputs the computed UL94 rating.
Target Customer Applications:
- Plastic resin, masterbatch, compound, and polymer additive manufacturing facilities.
- Electrical appliance, consumer electronics, connector, and housing production plants.
- Automotive interior trimming, wire harness sheath, and rubber component suppliers.
- Third-party fire testing laboratories and military electronics quality inspection centers.
Horizontal & Vertical Combustion Tester FAQ
Q1: What is the main difference between UL94 HB horizontal testing and V-0/1/2 vertical testing?
A: UL94 HB (equivalent to ISO 1210 / ASTM D635) measures the horizontal burning rate (mm/min) of a sample subjected to a 30-second flame exposure. V-0, V-1, and V-2 vertical tests (equivalent to ASTM D3801) evaluate self-extinguishing duration and flaming drippage that ignites surgical cotton after two 10-second flame exposures.
Q2: How does automatic timing improve UL94 testing accuracy over manual methods?
A: Manual timing using handheld stopwatches introduces human reaction errors (typically 0.2 to 0.5 seconds), which can cause borderline samples to fail or pass incorrectly. The SPCZ-05’s PLC system triggers timing synchronously with burner movement, ensuring ±0.1s precision.
Q3: What safety features are included to protect laboratory operators?
A: The instrument features a sealed combustion chamber with a tempered viewing window, an automatic gas solenoid cut-off valve, overcurrent protection, and an integrated exhaust blower to clear toxic fumes post-testing.
