Iec Standards Metadata Api Data: Dataset Structure and Field Coverage

Datadory delivers iec standards metadata api data covering comprehensive field definitions, entity mappings, and historical time series — structured for direct analytics and delivered on demand.

1,744 datasets. Pick your catch.

Can you redistribute IEC metadata you collect?

The safe line is metadata yes, documents no. IEC's copyright terms prohibit redistributing purchased PDFs outright, but nothing in the terms observed ties the catalog's factual fields - reference numbers, editions, dates, prices, committee assignments - to the same restriction, which is why price-comparison and compliance-index tools built on the search API exist publicly.

Where to go next

This page is the API-and-access chapter of a larger pool. Continue with:

  1. IEC power transformer standards list - the companion walkthrough that uses this API to build the actual transformer editions list, TC 96 filters and CHF budget included.
  1. IEC Standards Webstore vs EPRI - Power Grid Equipment Research - a head-to-head of the two API-backed sources if you are choosing where to integrate first.
  1. heavy-electrical-equipment data hub - the full industry index tying these clusters together.

Questions worth asking

How many IEC standards can I query through the API?

Roughly 30,482 publications sit in the search index, spanning every IEC international standard plus amendments, corrigenda, test-report formats and value-added versions. The query 'power transformers' returned 263 relevant records when verified on 2026-08-21, filtered down to true standards by selecting committee TC 96 and ICS 29.180.

Can the API tell me whether an IEC standard is current?

Yes. Every record ships a status field (PUBLISHED or REVISED) plus a lifecycle array listing all editions, amendments and corrigenda with dates and revision status. IEC 61558-2-2 shows ed 2.0 from 2007 marked REVISED and ed 3.0 dated 2022-10-19 marked PUBLISHED in a single response, so currency checks need no manual cross-referencing.

Is there a free alternative for US transformer regulations?

Yes. The GSA Catalog API v4 behind data.gov searches 552,271 harvested US datasets including EIA-860 generator and transformer data, FERC filings and DOE distribution-transformer efficiency rulemaking records. It needs a free api.data.gov key, DEMO_KEY allows 30 requests per hour, and the underlying federal records are largely commercial delivery terms.
