Peiyi PY-SP06 Horizontal & Vertical Flame Test Apparatus for Firestop Materials

Overview

The Peiyi PY-SP06 Horizontal & Vertical Flame Test Apparatus is a precision-engineered instrument designed specifically to evaluate the flame propagation resistance and self-extinguishing behavior of firestop materials in accordance with China’s national standard GB 23864—“Firestop Systems – Requirements and Test Methods”. This apparatus implements standardized burner-based ignition protocols under controlled atmospheric conditions within a calibrated combustion chamber. It supports both horizontal (HB) and vertical (V-0/V-1/V-2) orientation testing modes, enabling quantitative assessment of critical fire performance parameters including afterflame time, afterglow time, char length, and whether flaming droplets are produced during combustion. The system operates on the principle of reproducible radiant-convective thermal exposure using a precisely regulated propane or methane flame source, with strict geometric and dynamic constraints defined by GB 23864 to ensure inter-laboratory comparability.

Key Features

• Full compliance with GB 23864 test geometry, flame calibration, and timing requirements—including dual-axis specimen positioning (±450 mm vertical, ±180 mm horizontal) for precise alignment relative to the burner tip.
• Imported digital controller with high-stability PID regulation ensures consistent flame height (10–200 mm), fuel flow rate (10–100 mm/min), and pressure differential (5–200 mm H₂O) across repeated test cycles.
• Modular anodized aluminum fixtures provide dimensional stability and corrosion resistance; linear bearing–guided chrome-plated shafts enable smooth, backlash-free specimen translation during flame exposure.
• Wireless remote timer with 0.01 s resolution independently records ignition duration, afterflame time, and afterglow time—meeting traceability requirements for GLP-compliant laboratories.
• Matte black powder-coated interior minimizes optical interference and enhances visual contrast for accurate observation of flame spread and char formation.
• Tempered glass sliding viewport maintains structural integrity while permitting real-time monitoring without compromising chamber sealing or operator safety.
• Quiet-operation design reduces ambient noise during extended testing sessions, supporting use in shared laboratory environments.

Sample Compatibility & Compliance

The PY-SP06 accommodates rigid and semi-rigid firestop products including intumescent putties, sealants, wraps, mortars, and composite sheet materials with thicknesses up to 100 mm. Specimens are mounted using standardized clamping fixtures that replicate installation-relevant boundary conditions per GB 23864 Annex A. All mechanical adjustments—including burner tilt (0°–45°), flame angle, and vertical offset—are fully documented and repeatable. The apparatus satisfies metrological traceability requirements for ISO/IEC 17025-accredited testing laboratories when operated with certified calibration tools (e.g., copper block thermocouple verification kit, flame height gauge). While GB 23864 is its primary compliance target, the platform’s adjustable flame dynamics and specimen kinematics allow method adaptation for preliminary screening against UL 1479, ASTM E814, or EN 1366-3—subject to protocol validation per ISO/IEC 17025 Clause 7.2.2.

Software & Data Management

The PY-SP06 operates as a standalone hardware platform with no embedded software stack. All timing and positional parameters are managed via the imported digital controller’s front-panel interface and wireless remote unit. For laboratories requiring electronic recordkeeping, the device integrates seamlessly with third-party LIMS or ELN systems via RS-232 or USB-to-serial adapters (optional). Timestamped ignition and extinction events can be logged externally with audit-trail-capable software compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements—provided user-defined validation protocols are implemented. Calibration certificates for the controller, flame gauge, and stopwatch module must be maintained per ISO/IEC 17025 Section 6.4.

Applications

• Quality control testing of firestop assemblies prior to UL/CCC certification submission.
• R&D evaluation of novel intumescent formulations under standardized thermal insult conditions.
• Comparative analysis of aging effects (thermal cycling, humidity exposure) on flame-retardant efficacy.
• Failure mode analysis of fire barrier breaches in cable transits, pipe penetrations, and floor/wall joints.
• Training and proficiency testing for fire safety technicians in accredited testing facilities.

FAQ

Does the PY-SP06 support automated data export?
No—the device operates without internal data logging. External timestamp capture requires integration with compatible timing or LIMS software.
Can it be used for testing non-firestop materials such as cables or insulation?
It is not configured for UL 94 or IEC 60695-11-10 testing; specimen fixtures and flame geometry are optimized exclusively for GB 23864-compliant firestop configurations.
Is third-party calibration available?
Yes—certified calibration services for flame height, pressure differential, and timing resolution are offered by authorized metrology providers upon request.
What maintenance intervals are recommended?
Burner nozzle inspection and cleaning every 50 test cycles; annual verification of linear motion accuracy and controller calibration per manufacturer guidelines.
Does the apparatus include gas supply components?
No—users must provide certified propane or methane supply lines with pressure regulators meeting GB 23864 Section 5.2 specifications.
