When a connector housing enters a battery box review, the material data should go beyond a single UL94V-0 line. Reviewers need a material data sheet that names the base polymer, filler system, UL-recognized thickness range, and temperature index the material is rated to. Those details determine how the material performs at the wall thickness used in the housing and whether it fits the operating window of the battery box. A flammability report should follow, with the test standard, specimen thickness, and testing laboratory stated clearly—typically a UL Yellow Card or an equivalent third-party material certification. Alongside the material data, provide a housing drawing that shows wall thickness, mounting features, recommended torque or clamping, and any flatness or tolerance requirements. When comparing one battery connector supplier against another, the depth of that material packet is often the clearest difference. For the DM80 connector, published information covers a thermoplastic housing with a UL94V-0 material rating, listed for new energy automobile battery box and battery pack use. That set of facts is the starting point. Temperature index, IP rating, rated voltage, plating, and whole-product UL, CE, or IATF 16949 documents each need confirmation from the material data sheet or from the supplier. UL94V-0 on its own covers only the material rating. The FTC business guidance on advertising claims is a useful benchmark for suppliers and reviewers: performance claims should be supported by evidence and specific enough for an engineer to check. Asking a battery pack connector manufacturer for the full housing data package—material certificate, flammability report, drawing, and thermal data—turns the review into a document you can file. Ximeconn M12 Connectors publishes the DM80 housing information, and the remaining housing data is available through the data sheet request and engineering inquiry channels.
