Flagship dataset

ADR 2027, the complete Table A comparison

UNECE publishes the 2027 amendments as amendment instructions spread across several documents, not as a single comparison. This is that comparison: every Table A change from ADR 2025 to ADR 2027, column by column, searchable by UN number, with the source document cited on every row.

ADR reference library

The core reference set. Every page names the ADR provision it rests on, carries a last checked date, and ships a machine readable dataset.

Citing these resources

Cite the individual resource rather than this index, so a reader lands on the data. Every asset page carries a ready made citation in plain text, HTML and BibTeX, and the ADR 2027 release has a DOI at 10.5281/zenodo.21437099. Superseded versions stay reachable under /v/, so a citation made today still resolves to what it described.

Methodology

Sources: Official and primary documents, cited by reference number on every page. For ADR 2027 that is ECE/TRANS/WP.15/274 with Corr.1 and Add.1 and the UN depositary notification. The baseline is the BAM Datenbank GEFAHRGUT ADR 2025 dataset.
Extraction: Amendments are transcribed verbatim rather than paraphrased, then keyed to the UN numbers they affect. Where a check against the official text has not been completed, the page says so instead of implying it has.
Versioning: Every dataset carries a dataset version and a methodology version. Superseded releases stay reachable under /v/, and the current ADR 2027 release is archived with a DOI at 10.5281/zenodo.21437099.
Corrections: Every page carries a correction log and a reporting route. A reported error is dated and documented in the open. Nothing is silently overwritten.
Limitations: These are working references, not legal texts. The official ADR text and the national law implementing it govern.
Licence: CC BY 4.0, free to reuse commercially with attribution. Embeddable versions of the tables are offered on each page with the attribution link outside the frame.
