Import Bss 7238 Smoke Density Test To Aircraft Material — Buy in wholesale FOB from Supplier in China

BSS 7238 is the British Standard specification for measuring smoke density generated by solid materials used in aircraft cabin interiors, conducted in an NBS (National Bureau of Standards) smoke chamber. The test determines specific optical density values at defined intervals: Ds 1.5 records optical density at 1.5 minutes, Ds 4.0 at 4 minutes, and Dm represents the maximum smoke density reached during the exposure period. Ecosafene Technical Co., Ltd, based in Xiamen, Fujian Province, offers this fire-test service for aircraft material compliance, with sample preparation requiring drying at 60 degrees Celsius for 24 hours followed by conditioning at 23 degrees Celsius and 50 percent relative humidity.

The NBS smoke chamber method subjects conditioned specimens to controlled radiant heat or flame exposure while measuring light attenuation through the accumulated smoke. Standard specimen dimensions for this method typically measure 75 mm by 75 mm, with thickness determined by the actual aircraft material being qualified. Typical materials tested include thermoplastics, composites, textiles, foams, and film products intended for aircraft cabin applications. The standard requires reporting of Ds values at multiple time points to characterise both initial smoke release and peak smoke production, critical parameters for certifying materials to aviation fire-safety regulations.

Aircraft interior manufacturers, MRO (Maintenance, Repair and Overhaul) providers, and aerospace material suppliers commission BSS 7238 testing to demonstrate compliance with certification requirements from aviation authorities including EASA, FAA, and CAAC. Test results feed directly into flame, smoke, and toxicity (FST) data packages required for aircraft interior part approval. Buyers should confirm with Ecosafene Technical Co., Ltd whether their scope includes associated toxicity testing (such as BSS 7239, which is often paired with BSS 7238), the current accreditation status of their NBS chamber, and typical report turnaround times for this method.

Ecosafene Technical Co., Ltd operates from 8f Building 4, Chinese Academy of Sciences, No.255 South Duiying Road, Jimei District, Xiamen, Fujian Province, 361021, China. The supplier is listed at harbor trust tier with a response rate of 0.00 percent and no recorded average response hours, which indicates limited transactional history signals on this platform. The company profile focuses on fire-testing services for aircraft materials, specifically highlighting BSS 7238 smoke density testing capabilities using NBS chamber methodology with defined sample preparation and conditioning protocols.

The listing does not disclose company founding date, employee count, revenue figures, ISO accreditation details, or named aerospace clients. The supplier address places it within the Xiamen Jimei district, a zone with academic and research institute presence through the Chinese Academy of Sciences affiliation. Buyers should verify directly with Ecosafene Technical Co., Ltd their laboratory accreditation scope (specifically CNAS or equivalent recognition for BSS 7238), whether they hold OEM approvals from major aircraft manufacturers, and their capacity for concurrent testing volumes. The absence of response-rate data suggests this is either a newer listing or a supplier with limited platform engagement, making direct qualification dialogue essential before placing test orders.
