Writing “IEC 61851 compliant” into a charger specification does not, by itself, buy you anything checkable. IEC 61851 is a family of standards covering the whole conductive charging system, so the bare series number names no single test a product passed. An enforceable specification names three more things: the part of the series that applies to the equipment, the edition it was assessed against, and the document that proves it, the manufacturer’s declaration of conformity.
Key Takeaways
- “IEC 61851” names a family, not a test — a bare citation cannot be checked or enforced.
- A workable specification names the applicable part, the edition, and the declaration of conformity as the evidence.
- Connector shape, digital features and installation rules are separate lines — one standards citation cannot carry them.
- Compliance is per model and per market; get the exact model’s documents in writing before the order.
Why the Bare Series Number Is Not a Requirement
The series is structured in parts. Part 1 carries the general requirements — the framework the rest builds on — and further parts deal with DC charging equipment and its communication with the vehicle. Two chargers can both honestly cite “IEC 61851” while assessed against different parts, different editions, or both; a buyer comparing those listings learns nothing from the shared label.
The Fields a Specification Should Carry
| Field | What to write or ask for | Why it matters |
|---|---|---|
| Applicable part | The part of the IEC 61851 series that covers this equipment class, named in the requirement | Stops a general citation standing in for the applicable document |
| Edition | The edition year the product was assessed against | Editions differ; the year identifies which text the evidence describes |
| Declaration of conformity | The manufacturer’s declaration, supplied as a dated document with the bid | This is the evidence the claim rests on — not the brochure, not the listing |
| Test evidence behind it | The accredited test report the declaration is based on, available on request | Lets your side verify instead of trust; the testing route is covered in our guide to UL and ETL listing for EV chargers |
| Market fit | The market the evidence is for — the EN edition for Europe, or the North American documents where the order ships there | North America runs a parallel rulebook (SAE, UL, the NEC); an IEC declaration does not answer for it |
These fields work the same way in an RFQ, a tender schedule or a private-label agreement: fields to fill, not values this article can fill for you. What counts as a passing answer is set by your market’s rules and your own test house — confirm both before the specification goes out.
What the IEC 61851 Line Does Not Cover
One standards line often gets loaded with jobs that belong to other documents. Keep them as separate lines:
- Connector shape. Plug and inlet geometry is a different document’s job (the IEC 62196 series). Name the connector — Type 2, Type 1, NACS — as its own requirement.
- Digital behaviour. Communication features such as Plug and Charge and network protocols are specified separately; a 61851 line does not evidence them.
- Installation. Wiring rules are national; require installation to local code by a licensed electrician as its own clause.
- Samples prove the product, not the paper. Pair the document fields with a physical check — our guide to testing an EV charger sample before a bulk order covers that side.
How EVDANCE Handles This Paperwork
EVDANCE has manufactured chargers in Shenzhen since 2011 and exports to more than 30 countries, with private label available from 100 units — so specification paperwork is a routine part of an order. Our working rule matches this article: documents are confirmed per model, in writing, for the destination market. Buyers can start from our OEM and private-label programme and put their field list to us through the contact page. Never assume one model’s certification position from the range — ask for the exact model’s documents.
Frequently Asked Questions
Is “IEC 61851 compliant” on a listing enough to buy against?
No. Ask for the applicable part, the edition year and the declaration of conformity for the exact model. A supplier who has the evidence can produce all three quickly; a listing that cannot is telling you something.
Does an IEC 61851 declaration cover a charger for North America?
Not by itself. North America assesses chargers under its own documents — SAE standards, an NRTL safety listing, and the National Electrical Code for installation. Specify each market’s documents for that market.
Who checks the declaration against the specification?
Your side does. The comparison is mechanical: the standard and edition on the declaration either match your specification’s fields or they do not. For high stakes, an accredited test house can confirm the position.
