FFH Automotive Interior Vertical Burn Tester

Overview

The FFH Automotive Interior Vertical Burn Tester is a precision-engineered combustion test chamber designed to evaluate the vertical flame propagation behavior of interior materials used in motor vehicles—specifically curtains, sunshades, overhead linings, seat trims, and protective fabrics. It operates on the principle of controlled small-flame ignition under standardized thermal exposure conditions, measuring key fire performance parameters including afterflame time, afterglow time, and char length, from which vertical burn rate (mm/min) is derived. The system conforms strictly to internationally recognized regulatory frameworks governing flammability safety for automotive interiors, ensuring traceable, repeatable, and auditable test outcomes required for type approval and OEM component certification.

Key Features

• Stainless-steel sample holder frame (560 mm height × 170 mm width) with dual 2 mm-diameter fixing pins and adjustable 20 mm-height positioning pins for precise specimen alignment.
• U-shaped stainless-steel pressure plate (1.0 mm thickness) ensures uniform clamping force across variable-thickness specimens without distortion.
• Brass burner assembly compliant with dimensional and geometric specifications outlined in GB 32086–2015 and ISO 6941:2003; adjustable between vertical orientation and 30° tilt relative to the specimen plane.
• Precise burner-to-specimen distance control: top of burner nozzle fixed at 20 mm from bottom edge of specimen; linear actuation enables fine-tuning for specimens of varying thickness.
• High-voltage pulse ignition system with fail-safe automatic flame extinction upon completion of exposure duration or detection of flame-out conditions.
• Adjustable reference marking line mechanism accommodates specimens ranging from 0.5 mm to 5 mm thickness; integrated weight-driven timing sensor provides deterministic ignition and burn-front detection.
• PLC-based control architecture with industrial-grade touchscreen HMI enabling full automation of test sequence—including ignition, exposure timing, flame extinction, data acquisition, and burn-rate calculation.
• All timing functions (ignition delay, flame application duration, afterflame, afterglow) are fully automated and synchronized to internal real-time clock with ±0.1 s resolution.

Sample Compatibility & Compliance

The FFH tester accommodates flat, flexible textile and polymer-based substrates up to 560 mm in height and 170 mm in width, including woven/nonwoven fabrics, laminated composites, foams, and coated vinyls. Specimens are mounted vertically in free-hanging configuration per ISO 6941 methodology. Regulatory compliance is embedded into hardware design and operational logic: burner geometry, gas flow calibration, flame impingement angle, and measurement traceability align directly with GB 32086–2015 (China), ISO 6941:2003 (international harmonization), EN 407 (protective clothing), EU Directive 95/28/EC (motor vehicle interior materials), and Volkswagen’s internal specification PV 3357. The system supports audit-ready documentation for GLP and GMP-aligned quality systems, with timestamped event logs suitable for FDA 21 CFR Part 11-compliant environments when paired with validated software extensions.

Software & Data Management

While the base FFH model utilizes an embedded PLC and touch interface for standalone operation, optional firmware upgrades enable USB export of CSV-formatted test reports containing raw timestamps, calculated burn rates, pass/fail status per standard criteria, and operator ID metadata. All stored records include date/time stamps, test parameters (e.g., propane pressure, ambient temperature/humidity if externally logged), and digital signatures where enabled. Data retention complies with ISO/IEC 17025 Clause 7.5.2 requirements for result preservation, supporting laboratory accreditation workflows and third-party audit readiness.

Applications

This instrument serves Tier-1 suppliers, OEM engineering labs, and independent testing facilities engaged in pre-certification validation of interior trim components. Typical use cases include qualification of headliner fabrics against VW PV 3357, verification of curtain flame resistance per GB 32086–2015 for new energy vehicle programs, comparative screening of flame-retardant additives in polypropylene nonwovens, and root-cause analysis of ignition failure during production lot release. Its robust mechanical architecture and repeatable thermal delivery make it suitable for both R&D iteration and routine QC inspection.

FAQ

What standards does the FFH tester support out-of-the-box?

GB 32086–2015, ISO 6941:2003, EN 407, EU Directive 95/28/EC, and Volkswagen PV 3357—all implemented via physical burner geometry, fixture dimensions, and programmable exposure timing.

Is propane the only approved fuel gas?

Yes. Industrial-grade propane is specified in all referenced standards for flame stability, heat flux profile, and repeatability; substitution with butane or LPG blends invalidates compliance.

Can the system be integrated into a LIMS or enterprise QA platform?

Via optional RS-485 or Ethernet module (not included by default), the PLC controller supports Modbus RTU/TCP protocols for external data polling and remote start/stop commands.

What maintenance intervals are recommended?

Burner nozzle inspection and cleaning every 50 tests; pressure regulator calibration annually; touchscreen firmware updates per manufacturer bulletins.

Does the unit include calibration certificates?

A factory-assembled verification report is provided, covering dimensional checks, burner alignment, and timing accuracy; accredited third-party calibration is available upon request.
