Once you have an IEC 60947-2 pdf, you can decode any manufacturer’s datasheet. Look for these markings:

Cross-reference these values with the test sequences in Clause 8 of the standard (type tests). ⚠️ Do not search for “IEC 60947-2 pdf

Many countries adopt IEC standards as national standards (e.g., BS EN 60947-2 in the UK, DIN EN 60947-2 in Germany). You can purchase equivalent PDFs from:

Sites offering a free IEC 60947-2 pdf are almost always illegal. Penalties for using counterfeit standards can include fines and legal liability, especially if a certified product fails and causes injury. Moreover, old versions (e.g., the 2003 or 2007 editions) contain obsolete test methods. Always use the latest edition (currently Edition 6.0, published 2021-09, with Amendment 1: 2024).
