Q1155. How to translate industrial product standard certification documents?

Answered by the NYC Visa & Translation certified translation team

Industrial product standard certification in Thailand runs through the Thai Industrial Standards Institute (TISI), and the translation work surrounds both Thai certification for foreign products and foreign certification documents used in Thailand. The regulatory frame: products under mandatory TISI standards (a published list covering electrical appliances, construction materials, automotive parts, and others) must be certified before sale in Thailand — the application documents (product specifications, test reports from accredited laboratories, factory quality documentation) are filed in Thai, and foreign test reports and certificates are translated and legalised where required; products under voluntary standards follow the manufacturer's market choice. The document set: the test reports (from ISO/IEC 17025-accredited labs — the accreditation status is part of the evidence), the product specifications and drawings, the factory's quality management certification (ISO 9001 as the baseline), and the foreign certification marks' documentation where recognition applies. Translation rules that matter: the test report's results tables are numeric and transcribed exactly with the test standard's edition identified (a test to an outdated standard edition may not satisfy the current requirement); the specification's tolerances and units are preserved without conversion; and the certification scope (which models and variants the certificate covers) must be exact — selling a variant outside the certified scope is non-compliance. Practice points: confirm whether the product falls under a mandatory standard before importing (the TISI list is public); the certification process involves factory inspection for most categories; and keep the certificate's renewal on calendar. Confirm TISI's current requirements for the specific product category.
