A certificate of analysis is a quality documentation record issued by a manufacturer or a qualified testing laboratory that lists the test results for a specific batch or lot of material and confirms whether those results meet the approved specifications. In regulatory submissions and batch release, the CoA appears as a signed analytical document supporting drug substance, drug product, excipient, or device component quality.
In translation and localization, certificates of analysis appear in regulatory dossiers, import/export documentation, supplier qualification, and quality agreements. Translators may handle CoAs into multiple languages for customs, tender submissions, or manufacturing partners, and need to align test item names, methods, and limit units.
A frequent mistake is translating analytical method names literally or inconsistently, so a pharmacopoeial method such as “loss on drying” becomes confused with another procedure. Mixing decimal separators, units, or specification limits can also make the CoA appear out of specification and block batch release.
FDA, CE/MDR and NMPA reviewers assess the submitted wording itself. Regulatory bodies require traceable, accountable translation, and an inconsistent term can delay or fail a submission.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
