The integrity of power installations exceeding 1 kV relies entirely on the accuracy of the reference standards used during the design phase. Therefore, strict adherence to official documentation channels is not merely a bureaucratic requirement but a fundamental safety necessity. The "hottest" aspect of IEC 61936 is not its download speed, but its critical role in preventing catastrophic failure in high-voltage environments.
