Just want to know the exact length sample for wire/strand elongation testing. Is it 250mm or 500mm?

Hello Mr. Lua,

We had a discussion about this before.

At that time you indicated that you had purchased a 25 mm elongation tester but that the maximum length between the jaws was only 24.9 mm.

I, as moderator, replied at that time as follows:

"If there is a tolerance on the length of the conductor in the tester itself, it will be in your Standard. I suggest you look up the Standard and read it carefully. If the Standard does not allow a tolerance, then the tester must be modified."

This is still a valid answer as the Standard will clearly define the exact sample distance between the jaws of the elongation tester along with other requirements. We presume you require this for certified test reports to be sent to your customers.

The problem for us is that we don't know what country you live in, what wire products you are manufacturing, what sizes and shapes you are manufacturing, where you are sending your products and what Standards you are using to test your products. Your Quality Control Manager should know all of these things along with the elongation testing requirements.
