Praxisleitfäden zu CE, FCC, Batterieprüfung, Amazon-Compliance und Marktzugang – geschrieben für Hersteller, Exporteure und Amazon-Verkäufer. Keine allgemeine Theorie, sondern das, was Sie für den konformen Versand brauchen.
A charger that ships in the box and the same charger listed on its own are two different compliance cases. What evidence a separately sold accessory needs, and when the device report cannot be reused.
Leitfaden lesenA model number that does not match the label can stop a shipment or a listing. What a laboratory can amend, what it cannot, and when a correction is pointless because the product really needs retesting.
Leitfaden lesenClass A and Class B differ by 10 dB of emissions and by which manual statement you have to print. How the class is decided, and what choosing the wrong one costs.
Leitfaden lesenA firmware change only matters if it moved something that was measured. How FCC 2.1043 classes and the EU software-update test decide whether you retest, refile, or just record the version.
Leitfaden lesenYes, and it is common. What matters is who is named on the waybill, the customs declaration and the packing list, and how the box connects to your test booking.
Leitfaden lesenA failed EMC test is a measurement of one configuration, not a verdict on your design. How to read the data and tell a product problem from a setup problem before you redesign.
Leitfaden lesenIn ODM and private-label deals the Declaration of Conformity is signed by whoever markets the product under their own brand. How responsibility splits between brand, factory and importer, and what your ODM contract should say.
Leitfaden lesenEU law does not require CE testing in a European laboratory. What decides whether your Chinese test report is accepted: standard edition, accreditation scope, tested configuration, and the notified body exception.
Leitfaden lesenA test plan defines the configuration, modes, firmware and standards your product will be measured against. Here is what it contains, how to review it, and what goes wrong when it is never approved.
Leitfaden lesenWhat goes into a CE technical file, how it differs from a test report, who has to keep it for 10 years, and what to do when nobody can find the file.
Leitfaden lesenA factory move does not automatically invalidate a test report. What decides a retest is the construction, plus which certification schemes actually name the factory.
Leitfaden lesenWhy two labs cite different standards for the same product: how the regulation, product family, ports, edition and the buyer's contract each decide the test standard.
Leitfaden lesenWhen a buyer asks for a CE certificate that does not exist: which documents actually satisfy the request, which certificates really exist, and how to reply without losing the order.
Leitfaden lesenWhat to check before selling under your own brand with a factory test report: coverage of the shipped configuration, completeness of the report, and who signs the declaration of conformity.
Leitfaden lesenA customer says your product causes interference. What a passing report actually proves, the five configuration changes to check first, and when a regulator steps in.
Leitfaden lesenThe RCM mark, ACMA EMC and radio rules, EESS electrical safety levels and the responsible supplier requirement - what Australia and New Zealand actually ask for before you ship.
Leitfaden lesenAdapters, cables, antennas and batteries are part of the tested configuration. Which accessories to send, what a missing one costs you, and what to declare in writing.
Leitfaden lesenA notified body is a designated third-party assessor - required only in specific cases. When EU law forces one into your CE route, and when a test report is enough.
Leitfaden lesenA pre-certified radio module is usually cheaper - but only if its approval covers your antenna and modes. What a module grant covers, what it leaves out.
Leitfaden lesenUN38.3 is a transport test, not a market approval. When a lithium battery in your product needs it, and what the test summary your carrier asks for must contain.
Leitfaden lesenPre-compliance testing finds EMC and radio problems before the formal test. What it can and cannot prove, when it saves money, and when it is a wasted bench round.
Leitfaden lesenWhat a test report can and cannot do across markets - where measurements carry over to the US, UK or Korea, and where local approval routes stop reuse.
Leitfaden lesenA test report covers the models it actually tested, not a whole series. Here is when a new variant can be added by amendment and when a delta test is unavoidable.
Leitfaden lesenWhat a laboratory actually does between sample arrival and report: intake checks, worst-case selection, pre-scans, formal runs, and why mid-project questions are normal.
Leitfaden lesenA test report records testing, a certificate is issued by a third party, and a declaration of conformity is signed by you. Which document your buyer is really asking for.
Leitfaden lesenThe lab asks for your label artwork because the report describes one configuration and the label ships on every unit. What the artwork has to get right, and what turns into a retest.
Leitfaden lesenCE marking is recognised indefinitely in Great Britain, so most electronics do not need UKCA. Where UKCA still applies, what changed in October 2024, and how Northern Ireland differs.
Leitfaden lesenA component swap after certification does not automatically invalidate the report - but some changes do. Here is how to tell which changes need retesting, and what evidence closes the rest.
Leitfaden lesenCertification testing takes days to several weeks - but the bench is only one part of the clock. Here is where the calendar time actually goes, and what you control.
Leitfaden lesenA test report carries no legal expiry date. What decides whether an old report is still accepted: the standard edition it cites, the product it describes, and your buyer's own rules.
Leitfaden lesenSix checks before you commit to a laboratory: accreditation scope for your exact standard, who accepts the report, full-configuration coverage, and how changes are handled.
Leitfaden lesenThe recurring root causes behind EMC test failures - power supply filtering, grounding, cables, enclosure shielding, clock layout and configuration drift - and which fixes actually clear the limit line.
Leitfaden lesenProduction tooling is not ready but the buyer wants the report. When engineering samples are acceptable for certification testing, when they are not, and which differences force a retest on the production version.
Leitfaden lesenSamples are already at the laboratory and the quote is suddenly higher. The three real reasons testing costs grow mid-project, which ones are avoidable, and how to lock the scope before you start.
Leitfaden lesenOb Ihr Produkt eine FCC ID oder nur eine SDoC braucht, läuft auf eine Frage hinaus: enthält es einen Funksender? Wie sich die beiden FCC-Wege unterscheiden und wo Projekte schiefgehen.
Leitfaden lesenEine nicht bestandene Prüfposition ist ein Ergebnis, keine Ablehnung. Was das Labor Ihnen sagen sollte, wer die Korrektur entscheidet, was eine vollständige oder teilweise Nachprüfung auslöst und was der Fehlschlag mit Ihrem Bericht und der Konformitätserklärung macht.
Leitfaden lesenGleiches Produkt, gleiche Normen, drei Labore, drei sehr unterschiedliche Preise. Der größte Teil der Lücke ist der Umfang - was jedes Angebot einschloss und was es stillschweigend wegließ. So vergleichen Sie Angebote richtig.
Leitfaden lesenFCC-Gerätezulassung, UL- und NRTL-Listung, DOE-Netzteilregeln und Spielzeuganforderungen - was für den US-Markt gesetzlich vorgeschrieben ist und was Ihr Käufer ohnehin verlangt.
Leitfaden lesenWas ein Prüflabor in Ihrer Bedienungsanleitung tatsächlich liest, warum der Prüfbericht sie zitiert und was passiert, wenn die geprüfte Version nicht die versandte ist.
Leitfaden lesenEin Prüfangebot entschlüsselt: Was jede Position abdeckt, was standardmäßig enthalten ist und die fünf Situationen – Adapterwechsel, zusätzliche Funkmodi, Nachprüfungen – die zu Zusatzkosten führen.
Leitfaden lesenWas Amazon tatsächlich verlangt, wenn ein Elektronik-Listing beanstandet wird: Prüfberichte, FCC- und CE-Dokumente, Angaben zur verantwortlichen Person – und die Ablehnungsgründe, die Sie vermeiden sollten.
Leitfaden lesenDie Unterlagen, die ein Prüflabor vor Prüfbeginn benötigt – Anleitung, Stückliste, Schaltpläne, Label-Artwork, Funkdaten – wofür jedes einzelne gebraucht wird und was schiefgeht, wenn eines fehlt.
Leitfaden lesenCE-Prüfungen haben keinen Einheitspreis. Sehen Sie, wofür jede Position in einem CE-Angebot steht, welche Posten die Kosten treiben und wo Projekte nach Auftragserteilung teurer werden.
Leitfaden lesenCE-Kennzeichnung, EMV, NSR, RED, RoHS, REACH und GPSR erklärt für Elektronik für den europäischen Markt – und welche Dokumente Ihr Käufer oder Amazon tatsächlich verlangen.
