Technological Features of FCZ-50 Textile Flammability Tester
- Dual Conditioning & Ignition Test Profiles: Fully supports both Condition A (12 s ignition with propane/butane for standard-conditioned fabrics) and Condition B (3 s ignition with ≥97% purity methane for oven-dried specimens).
- Standardized Char Length Tear Weight System: Includes five precision-calibrated weights (54.5 g, 113.4 g, 226.8 g, 340.2 g, e 453.6 g) mapped directly to fabric weight per unit area (≤101 g/m² to ≥650 g/m²) for accurate tear-strength damaged length calculation.
- Precision Bunsen Burner Assembly: Features an 11 mm internal nozzle diameter Bunsen burner ensuring consistent gas flow velocity and stable flame geometry during exposure.
- Enclosed Draft-Free Combustion Chamber: Compact stainless steel chamber (329 milímetros × 329 milímetros × 767 milímetros) insulates the flame from ambient air currents while observing combustion via a clear front window.
- High-Precision Measurement & Timing: Electronic timer measuring afterflame and afterglow durations with 0.1 precisão, combined with 1 mm linear resolution for damaged length reporting.

Arquitetura do sistema & Testing Workflow of FCZ-50 Textile Flammability Tester
Fluxo de trabalho de teste padronizado:
- Cut specimens to 300 milímetros × 89 mm and condition according to Condition A (standard atmosphere) or Condition B (oven-dried at 105°C).
- Mount the sample inside the 356 milímetros × 51 mm vertical specimen holder and suspend it in the combustion chamber.
- Select test gas (propane/butane for Condition A or Methane ≥97% for Condition B) and set ignition timer (12 s or 3 é).
- Apply flame exposure. Automatically record afterflame time (duration sample continues burning after burner shuts off) and afterglow time.
- Attach the designated weight (based on fabric mass per unit area from Table 2) to the bottom corner of the burned sample, lift slowly, and measure the resulting damaged length (char length).
Aplicativos de clientes-alvo:
- Protective apparel, firefighter turnout gear, and welder suit manufacturing plants.
- Children’s sleepwear, curtain/drapery, and home textile quality control laboratories.
- Aerospace interior and military fabric certification organizations.
FCZ-50 Textile Vertical Flammability Tester FAQ
1º trimestre: What parameters are measured during a vertical fabric flammability test?
UM: The FCZ-50 evaluates three critical parameters: Afterflame Time (duration of visible flame after burner removal), Afterglow Time (duration of flameless glowing combustion), and Damaged Length (char length measured using standardized tear weights).
2º trimestre: How is the char length weight chosen for testing?
UM: The tear weight is determined by fabric mass per unit area (g/m²):
- ≤ 101 g/m²: 54.5 g weight
- > 101 para ≤ 207 g/m²: 113.4 g weight
- > 207 para ≤ 338 g/m²: 226.8 g weight
- > 338 para < 650 g/m²: 340.2 g weight
- ≥ 650 g/m²: 453.6 g weight
3º trimestre: Can this device be used for ASTM D6413 workwear testing?
UM: Sim. The vertical specimen frame, 11 mm Bunsen burner nozzle, 12 s ignition timer, and specified char length weights align with ASTM D6413 requirements.
