Official IEC PDFs are not password protected for opening, but they may have usage restrictions (e.g., no editing). If a file asks for a password to view, it is likely an illegal crack attempt.
The only reliable fix for missing pages, watermarks, or outdated versions is buying the standard from the IEC Webstore or your national body (ANSI, BSI, DIN). If you are stuck with a scanned copy

When someone searches for "IEC 600601 pdf fix," they are usually trying to solve one of three specific, maddening errors:
1. The "Unit Conversion" Error (Most Common) In older scanned PDFs (pre-2010), the tables for terminal torque values mix up Nm (Newton meters) and lbf-in (pound-force inches). A scanned copy might show "0.5 Nm" but the visual scan line cuts off the "0." so it reads "5 Nm." That is a 1000% increase in torque. The "fix" here is manually annotating the PDF to correct the decimal place.
2. The "Missing Table Reference" Glitch
IEC documents are notorious for nested footnotes. In a properly rendered PDF, footnote a) says "For class 1, use column B." But in many corrupted downloads, the hyperlink is dead, or the footnote block is missing entirely. The "fix" is to copy/paste the footnote from a different section of the PDF, effectively rebuilding the document manually.
3. The "Broken Formula" Issue
Clause 4.3.2 often contains a logarithmic formula for life expectancy. In a text-based PDF export, the superscripts and subscripts get flattened. 10^3 becomes 103. Engineers are literally rewriting the math by hand in the margins of their digital PDFs.
