TESTech TTech-GBT16556C Full-Face Respirator Flame Resistance Tester (Compliant with EN 136, GB/T 16556–2007 & GA 124–2013)

Overview

The TESTech TTech-GBT16556C Full-Face Respirator Flame Resistance Tester is a purpose-built, integrated combustion testing system engineered for precise evaluation of flame resistance performance in personal protective equipment (PPE) used by firefighters and emergency responders. Designed in strict accordance with three internationally referenced standards—EN 136:2021 (Respiratory protective devices – Full-face masks – Requirements, testing, marking), GB/T 16556–2007 (Self-contained open-circuit compressed air breathing apparatus – Technical requirements, test methods), and GA 124–2013 (Firefighter’s self-contained breathing apparatus – Technical specification)—this instrument delivers repeatable, traceable, and auditable test outcomes for full-face respirator masks, harness straps, buckles, cylinder covers, and associated components. Its dual-test-platform architecture enables concurrent or sequential execution of both EN 136–specified facepiece flame exposure and GA 124–mandated harness strap flammability assessment under controlled thermal conditions. The system operates on the principle of standardized radiant and convective heat exposure using calibrated propane-air premixed flames, with real-time thermal monitoring, automated ignition timing, and fail-safe gas cutoff protocols to ensure operator safety and procedural integrity.

Key Features

• Integrated dual-test platform supporting simultaneous compliance verification per EN 136 (full-face mask) and GA 124–2013 (harness/backplate assembly)
• PLC-based control architecture with industrial-grade 7-inch capacitive touchscreen HMI for intuitive program selection, parameter setting, and real-time status visualization
• Full stainless-steel construction of all fixtures, clamps, shields, and burner mounts—resistant to oxidation, thermal degradation, and chemical corrosion
• Dual independent combustion modules: six precision-machined imported nozzles for facepiece testing (adjustable height, 250 mm ±2 mm from specimen surface); adjustable Bunsen burner with 40 mm flame height and thermocouple-verified 800 ±50 °C at 20 mm above tip for strap testing
• Automated gas management: digital pressure regulation (0–10 kPa), needle-valve flow control, programmable 5 s / 20 s ignition-and-shutoff sequences, and redundant automatic gas cutoff upon timer expiration
• Embedded data acquisition system recording flame exposure duration, gas pressure, and test initiation/termination timestamps; all results stored locally with ISO-compliant file naming and timestamping
• Ergonomic cabinet design (1400 × 650 × 1300 mm) with powder-coated steel enclosure, integrated ventilation ducting, and dedicated flame containment zone

Sample Compatibility & Compliance

The TTech-GBT16556C accommodates standard-sized full-face respirator masks (per EN 136 Annex A headform geometry), as well as flat or contoured backplate assemblies, shoulder straps, waist belts, and buckle systems conforming to GA 124–2013 Clause 5.11.2 and 5.11.3. Specimen mounting utilizes non-reactive stainless-steel clamps and alignment jigs ensuring consistent orientation and distance-to-flame repeatability. All test procedures align with documented standard clauses—including flame application angle, exposure duration (10 s for facepieces, 20 s for straps), post-flame afterglow observation window (up to 30 s), and pass/fail criteria based on hole formation, melting, dripping, or sustained flaming. The system supports GLP-aligned operation through user-accessible audit logs, electronic signature fields (via optional password-protected admin mode), and exportable CSV reports suitable for regulatory submissions under CNAS, CMA, or third-party certification bodies.

Software & Data Management

The embedded firmware provides a deterministic, non-Windows-based operating environment optimized for laboratory durability and electromagnetic compatibility. Test protocols are preloaded per standard version (e.g., “EN136_FaceMask_v2021”, “GA124_Harness_v2013”) and cannot be modified without administrative credentials. Each test cycle generates a unique identifier incorporating date, time, operator ID (if logged), and sample batch code. Raw data—including start/stop timestamps, pressure readings, and ignition confirmation signals—are stored in non-volatile memory with write-protection enabled. Export options include USB-stick transfer of encrypted .csv files compatible with LIMS integration. While not FDA 21 CFR Part 11 certified out-of-the-box, the system architecture supports future validation packages for GMP-regulated PPE manufacturing QA/QC labs.

Applications

This tester serves quality assurance laboratories within fire equipment manufacturers, national fire product inspection centers (e.g., China National Fire Equipment Quality Supervision and Inspection Center), and third-party certification bodies conducting type approval per CCC, CE, or NFPA 1981–2022 Annex B requirements. It is routinely deployed for incoming raw material screening (e.g., silicone elastomers, thermoplastic polyurethanes), in-process verification of molded mask shells, final product release testing, and root-cause analysis of field-reported burn-through incidents. Its reproducible thermal exposure profile also supports comparative R&D studies evaluating novel flame-retardant additives, intumescent coatings, or hybrid composite laminates intended for next-generation respiratory PPE.

FAQ

Does this instrument comply with EN 136:2021 edition?
Yes—the facepiece test module meets all mechanical, dimensional, and thermal requirements specified in EN 136:2021 Clauses 4.11 and Annex C, including nozzle configuration, flame impingement geometry, and post-test visual assessment criteria.
Can it test non-standard respirator geometries?
The headform fixture is fixed per EN 136-defined anthropometric dimensions; custom adapters may be fabricated but require revalidation against standard reference specimens.
Is calibration traceability provided?
A NIST-traceable calibration certificate for pressure transducers and thermocouples is issued with each unit; annual recalibration services are available through authorized TESTech service centers.
What electrical safety certifications does it hold?
The system complies with IEC 61010-1:2010 for laboratory electrical equipment and carries CE marking for EMC and low-voltage directive conformity.
Is remote diagnostics supported?
Basic Ethernet port enables local network connectivity for firmware updates and log retrieval; remote access requires on-site IT security review and VLAN segmentation per institutional policy.
