The NES 713 Navy Engineering Smoke Toxicity Test Chamber is a specialized fire testing instrument designed to evaluate the toxicity of combustion products generated by materials under controlled burning conditions. In accordance with the NES 713 standard, the chamber determines the smoke toxicity index produced after the combustion of a 100 g specimen. The system provides a controlled flame source, uniform smoke mixing, and multi-point gas sampling to support accurate assessment of toxic gases released during material combustion. It is widely used in industries with extremely high fire safety requirements, including marine engineering, rail transportation, and aerospace applications.
Application
The NES 713 Navy Engineering Smoke Toxicity Test Chamber is suitable for evaluating the combustion smoke toxicity of a wide range of materials, including but not limited to:
Marine engineering materials (interior panels, insulation materials, coatings)
Shipbuilding cables and cable sheathing materials
Rail transit interior decorative materials and flooring systems
Aerospace structural and cabin materials
Polymer composites and elastomer products
Fire-retardant materials and protective coatings
Typical test products include plastic sheets, rubber components, cable assemblies, composite laminates, and coated metal or non-metal substrates.
Standards
The equipment is designed and manufactured in compliance with the following standard:
(1) NES 713 – Determination of the Toxicity Index of the Products of Combustion from Small Specimens of Materials
