The International Electrotechnical Commission (IEC) has published a standard for high-voltage test techniques, which is IEC 60060-1:2013. This standard provides general definitions and requirements for high-voltage testing of electrical equipment and systems. The standard is divided into several parts, and Part 1 covers the general definitions and requirements.

He hit the red button.
The standard provides guidelines for measuring test voltages, including: IEC 60060-1: High-voltage test techniques – Part 1:
He looked at his data. His peak was fine. His tail time was 48 microseconds—acceptable. But his front time? His peak was fine
IEC 60060-1:2013 emphasizes the importance of safety during high-voltage testing and provides guidelines for:
According to the PDF, a standard lightning impulse must have a front time of 1.2 microseconds (with a tolerance of ±30%) and a tail time of 50 microseconds (with a tolerance of ±20%).
