IDM H0002 Horizontal Burning Tester for Plastics and Textiles

Overview

The IDM H0002 Horizontal Burning Tester is a precision-engineered benchtop instrument designed to evaluate the horizontal flame spread behavior and self-extinguishing characteristics of polymeric materials, textiles, and automotive interior components under standardized thermal exposure. It operates on the principle of controlled open-flame ignition in accordance with horizontal orientation test protocols—where a defined flame is applied to one end of a horizontally clamped specimen, and the rate of flame propagation, afterflame time, afterglow time, and char length are quantitatively measured. This method provides critical fire safety data required for material qualification in transportation, aerospace, and building product sectors. The tester features a rigid 304 stainless steel chassis, integrated thermal shielding, and a large-dimension borosilicate viewing window enabling real-time visual observation without compromising operator safety or test integrity.

Key Features

• Electronically actuated gas shutoff valve for precise, repeatable flame initiation and immediate termination—ensuring compliance with timing requirements in ASTM D5132 and ISO 3795.
• Calibrated vertical scale (0–50 mm) mounted adjacent to the burner nozzle, facilitating accurate flame height adjustment per standard specifications (e.g., 38 mm ± 2 mm for FMVSS 302).
• U-shaped stainless steel sample holder (100 mm × 355 mm), machined to dimensional tolerances specified in SAE J369 and GMW 3232, ensuring consistent specimen alignment and thermal boundary conditions.
• Front-access hinged door with integrated burner mount and top-mounted hinged lid—optimized for rapid specimen loading, flame positioning, and post-test residue inspection.
• Thermally insulated enclosure with double-wall construction minimizes ambient heat influence and maintains stable chamber temperature during sequential testing.
• Modular electrical architecture supporting dual-voltage input (110 VAC / 220–240 VAC) and frequency compatibility (50/60 Hz), certified to IEC 61000-6-3 for electromagnetic emissions.

Sample Compatibility & Compliance

The H0002 accommodates flat, rigid, or semi-rigid specimens up to 13 mm thick, including thermoplastics (e.g., PP, ABS, PC blends), woven/nonwoven textiles, laminated composites, and foam-backed upholstery materials. All sample fixtures conform to dimensional and surface-flatness criteria outlined in ISO 3795 Annex A and ASTM D5132 Section 7. The instrument’s mechanical design and operational sequence satisfy the apparatus requirements of FMVSS 302 (U.S. DOT), GM9070P (General Motors), and MVSS 302 (revised nomenclature for FMVSS 302). Test reports generated using this system support GLP-compliant documentation when paired with validated manual recording procedures; optional digital logging modules can be configured to meet FDA 21 CFR Part 11 audit-trail requirements.

Software & Data Management

The H0002 operates as a standalone hardware platform without embedded firmware or proprietary software. All measurements—including flame application duration, afterflame time (up to 300 s resolution), afterglow time, and char length—are recorded manually using calibrated stopwatches and rulers traceable to NIST standards. For laboratories requiring electronic data capture, third-party timing systems (e.g., Keyence FT-M1 or Omron H3CR-F) may be interfaced via dry-contact trigger outputs. Raw test data aligns with ASTM E178 statistical guidelines for repeatability and reproducibility assessment. Calibration records for burner gas flow (2.0 kg/h ± 5% at 2.8 kPa) and flame geometry must be maintained per ISO/IEC 17025 Clause 6.4.3.

Applications

• Automotive OEM qualification of seat fabrics, headliners, door trims, and instrument panel substrates against GMW 3232 and Ford WSS-M2700-B.
• Regulatory submission testing for aircraft interior materials per FAR 25.853(a) Appendix F Part I (when used in conjunction with vertical burn apparatus).
• QC screening of flame-retardant additives in polyolefin compounds prior to extrusion validation.
• Research-level flammability benchmarking of bio-based polymers and recycled textile fibers under ISO 3795 comparative protocols.
• Supplier audits and first-article inspections where horizontal burn performance is contractually mandated.

FAQ

Does the H0002 comply with FMVSS 302 for U.S. automotive certification?
Yes—the mechanical configuration, burner specification (38 mm flame height, propane/natural gas compatible), and specimen holder dimensions fully satisfy the apparatus requirements of FMVSS 302, provided gas supply pressure and flow rate are verified per SAE J369 Annex C.
Can the instrument be used with propane instead of natural gas?
Yes—burner orifice and pressure regulator settings are field-adjustable for propane (C₃H₈) operation; calibration certificates must reflect the fuel type used during verification.
Is third-party calibration service available?
IDM authorizes ISO/IEC 17025-accredited calibration providers to perform annual verification of flame height scale linearity, gas flow rate accuracy, and timer synchronization—documentation follows ILAC MRA guidelines.
What maintenance is required between tests?
Burner nozzle cleaning with compressed air or stainless steel wire brush is recommended after every 10 test cycles; viewing window should be wiped with ethanol-dampened lint-free cloth to maintain optical clarity.
Are spare parts such as U-shaped holders or burner tips stocked internationally?
Yes—standard consumables (stainless steel sample holders, brass burner nozzles, tempered glass panels) are held in regional distribution hubs across EU, NA, and APAC regions with lead times under 5 business days.
