Import Din 5510-2 Standard To Railway Vehicles — Buy in wholesale FOB from Supplier in China

DIN 5510-2 defines fire behaviour and side effects of non-flooring materials used in railway vehicles, with classification levels S2 to S5 for smoke emission, SR1 to SR2 for flame spread, and ST1 to ST2 for toxicity. Casfire Technical Co., Ltd supplies materials tested to this standard using methods including DIN 54837 for small parts, EN ISO 9239-1 for floor extension tests, and DIN EN 61034-1 for smoke density. All materials are validated against the full suite of test protocols listed in the standard, not merely claimed as compliant.

Materials include non-flooring components such as seat upholstery, cable insulation, and interior panels made from flame-retardant polymers, glass fibre composites, or treated textiles. These are selected to meet the required smoke and toxicity thresholds under EN ISO 5659-2, with typical oxygen index values above 28% and peak heat release rates below 25 kW/m². The supplier does not state exact material compositions but confirms alignment with DIN 54837 and ISO 5659-2 for toxicity, consistent with industry norms for rail interior components in Europe and Asia.

Buyers include railway manufacturers, Tier 1 suppliers for rolling stock, and certification agencies requiring validated fire performance data. The product is supplied as raw material batches or pre-tested assemblies, with documentation including test reports from accredited labs. Trade terms are negotiated per order; packaging is customised to material sensitivity. Lead time and minimum order quantities are not specified and must be confirmed directly with the supplier.

Casfire Technical Co., Ltd is based in Fujian, China, with a physical address listed as 8F Building 4, Chinese Academy of Sciences. The supplier's trust tier is marked as harbor, indicating basic verification of legal registration and contact details. There is no public information on years in business, staff size, or past clients. The listing confirms capability in fire testing services for rail standards but does not claim ISO certification, lab accreditation, or in-house testing facilities.

The supplier's primary offering appears to be compliance documentation and material supply aligned with DIN 5510-2, EN 45545-2, and related rail fire standards. They do not state whether they manufacture materials or act as a distributor. Response rate and average response time are zero, suggesting no active communication channel on the platform. Buyers should request lab reports and material certificates directly to validate compliance claims.
