Product Overview of FCZ-50 Vertical Flammability Tester

The FCZ-50 vertical burning test chamber is a dedicated apparatus for evaluating the vertical combustion performance of all kinds of textiles and finished textile products. The closed transparent combustion cabinet ensures safe testing while allowing full visual observation of specimen burning status. The integrated touch control panel, precision pressure gauge and standardized Bunsen burner realize fully automatic timing and ignition control, delivering repeatable, audit-ready test data that fully complies with GB/T 5455-2014 standard requirements.

Core Standard Compliance

FCZ-50 fully executes GB/T 5455-2014 Textiles – Burning Behaviour – Determination of Damaged Length, Afterglow Time and Afterflame Time of Vertically Oriented Specimens, the core mandatory standard for domestic textile fire resistance classification and export textile safety inspection.

Key Technical Parameters

1. Combustion cabinet internal size: 329±2 mm × 329±2 mm × 767 mm
2. Specimen holder inner dimension: 356 mm × 51 mm
3. Standard Bunsen burner nozzle diameter: 11 mm
4. Measurement resolution: Time accurate to 0.1s, length accurate to 1mm
5. Ambient test environment: Temp 10–30°C, RH 30%–80%
6. Power supply: 220V / 50Hz, rated power 100W
7. Overall equipment dimension: 632mm × 332mm × 852mm

Two Standard Test Conditioning Modes (As Specified in GB/T 5455-2014)

The tester supports two independent specimen pre-treatment schemes with different gas and ignition time requirements; test results from two modes cannot be intercompared:

• Condition A (Standard Atmosphere Conditioning) Specimen size: 300mm × 89mm; 5 warp + 5 weft samples (10 total) Fuel gas: Industrial propane / butane mixed gas Ignition duration: 12 seconds
• Condition B (Oven Drying Conditioning) Specimen size: 300mm × 89mm; 3 warp + 2 weft samples (5 total) Fuel gas: Methane (purity ≥97%) Ignition duration: 3 seconds

Standard Weight Matching for Different Fabrics

Equipped with a complete set of standard counterweights for different fabric areal densities to meet vertical sag test rules:

• ≤101 g/m²: 54.5g weight
• 101–207 g/m²: 113.4g weight
• 207–338 g/m²: 226.8g weight
• 338–650 g/m²: 340.2g weight
• ≥650 g/m²: 453.6g weight

Outstanding Equipment Advantages

1. Fully enclosed safety combustion cabinet with transparent observation window, effectively isolating flame and toxic fumes during testing.
2. Integrated touch screen control + real-time pressure gauge monitoring gas supply pressure, stable flame output for consistent ignition.
3. High-precision timing and length measurement module eliminates manual reading errors, auto-record three core indicators: afterflame time, afterglow time, damaged length.
4. Complete supporting accessories: standard specimen clamps, full set of grading counterweights, dedicated gas pipeline and ignition burner, one machine ready for testing after installation.
5. Compact desktop design, occupies little lab space, easy to move and maintain with low daily operation cost.
