Rail transit testing
Basic introduction
Beice Testing provides comprehensive testing and analysis services
for rail transit materials, including locomotive interior parts,
exterior parts, decorative materials, flame retardant materials,
and components. It provides professional and reliable testing and
analysis services based on railway standards and national
standards, focusing on toxic and hazardous substances, combustion
performance, physical and chemical properties, and reliability.
Testing services
Interior decoration materials for locomotives
Body materials, flooring, insulation and packaging materials,
interior decoration materials, air conditioning ducts, wires and
cables, and other non-metallic materials.
Vehicle functional material testing
Structural materials, decorative materials, adhesives, paints and
coatings, rubber and plastic products, textiles, and carpets.
Test items
Combustion performance test:
Oxygen index, combustion performance, smoke density, toxic gas
concentration, combustion level (flammable level), dripping level
(liquid level), smoke level (smoke level), smoke toxicity (smoke
toxicity index), surface extension of flame or critical radiation
heat flux during fire extinguishing, surface extension of flame,
smoke density, smoke toxicity, oxygen index, surface extension of
flame or critical radiation heat flux during fire extinguishing,
surface extension of flame, smoke density, smoke toxicity, oxygen
index.
