Regional versions like BS EN IEC 60099-5 can be found on the BSI Knowledge platform or via the ANSI Webstore for North American users.
Consider:
An engineer who relies on a modified or outdated PDF is, as one industry expert notes, working outside of a version-controlled, governed system. The error from using superseded or incorrect data will not surface until a design review, a certification audit, or worse, after equipment has failed. By then, the cost of rework, redesign, and liability is immense. iec 600995 pdf patched
The first sign of trouble in your search query is that iec 600995 does not exist in any official IEC catalogue. This suggests one of three things:

IEC 60099-5 is a standard that specifies the requirements for surge arresters used in electrical power systems. Surge arresters are devices that protect electrical equipment from voltage surges, spikes, and other forms of overvoltage. They are commonly used in power transmission and distribution systems, as well as in industrial and commercial applications.
A landmark legal case in Shanghai, China, serves as a powerful warning. A defendant was convicted of copyright infringement for operating several websites that sold pirated ISO and IEC standards without permission. The court ruled that these standards are works protected by law. The individual was found guilty of "reproducing and distributing" copyrighted works, was sentenced to three years in prison (suspended for four years), and was fined 180,000 RMB. This is not an isolated incident; it highlights that the illegal trade in standards is taken very seriously by legal authorities. The official procurement of standards is protected by regulations that explicitly prohibit the use of illegal copies and mandate the use of authorized channels. By then, the cost of rework, redesign, and
