DX8390 Material Smoke Toxicity Hazard Classification Test Machine ISO 19700 GB 20285 Gas Analyzer

DX8390 Material Smoke Toxicity Hazard Classification Test Machine

The DX8390 is a dedicated test apparatus for the hazard classification of smoke toxicity generated by materials under stable smoke production conditions. It is designed for laboratories, material manufacturers and third-party testing institutes that must evaluate how much toxic hazard a burning material releases into the fire effluent.

The machine supports the two internationally recognised routes of hazard grading: the GB route, which classifies toxicity by the GB/T 20285 test procedure, and the ISO route, under which the fire effluent is quantified by a gas analyser (supplied as an optional accessory).

Compliant Standards

• GB/T 20285-2006 — Smoke toxicity hazard classification of materials
• ISO 19700-2006 — Controlled equivalence ratio method for the determination of hazardous components of fire effluents

How the Hazard Grading Works

Key Performance Data

Machine Highlights

• Dual-standard coverage — one machine serves both GB/T 20285 and ISO 19700 test programmes, so laboratories do not need separate rigs for domestic and export certification work.
• precision gas analyser — the effluent measuring chain is built around an imported precision analysing unit, giving stable readings across long test campaigns.
• Traceable temperature control — the programmed temperature curve is logged against the measured curve, so deviations are visible directly on the chart during the run and in the test report.
• Adjustable gas flow — the 0–20 L/min range covers the dilution and flow settings required by different material classes and test protocols.
• Built for routine laboratory work — the test chamber, sampling line and analysing unit are arranged for repeated daily testing with straightforward cleaning and calibration access.

Typical Applications

• Hazard grading of smoke toxicity for building and interior finishing materials
• Fire effluent assessment of cables, textiles, foams and composite panels
• Material research and development where smoke toxicity is a design constraint
• Third-party testing laboratories issuing GB/T 20285 and ISO 19700 reports

Scope of Supply

• DX8390 smoke toxicity hazard classification test machine
• Precision gas analysing unit
• Temperature control and recording system with curve comparison output
• Operation and maintenance manual, factory calibration report
• Gas analyser for the ISO route quoted separately as an optional accessory

Service

Installation guidance, commissioning support and operator training can be arranged. Spare parts and calibration service are available for the lifetime of the machine. OEM branding and customised reporting formats are accepted for distributors.

Please tell us the material types you test and the standard you report against. We will confirm the configuration, the optional gas analyser scope and the delivery schedule for your laboratory.
