The 'correct' answer is probably something like http://www.whsalisbury.com/blankets/images/blankets.pdf Page 14 states: “Tested to 20kV — Maximum use 17,000V”.

That is an incredibly stupid exam question, based on a cryptic ASTM Standard. Knowing that sort of minutia does not demonstrate any significant trade knowledge.

But you knew it.....


One of my journeyman's test questions was how to convert Fahrenheit to Celsius.

It is in the code book both ways and if I need the formula I can find it.

This demonstrates trade knowledge how?
