Wire/Conductor Elongation Tester Verification

hello guys. need your inputs here.
i am verifying now a elongation tester(for single strand copper conductor).
as per standard it says only that sample must be approx 25mm. I verified the elongation tester jigs but it only measures 24.8mm. i am so very confuse because the standard didnt say the tolerance of the sample.
my problem is that i dont know what is my permissible error for the testers jigs distance. please share your knowledge if you have some experience with this equipment.

thanks in advance

It seems to be OK 24.8, because you can still fix a 25mm exact wire.
Just open the jig a bit so that it measures 25.0 mm. At this place your force is zero, and thereafter the elongation force is applied.
As you are more interested in finding the % elongation at break, 25.00 or 24.8 can still be used in the calculations, when you know the elongated length at break.
That is the reason why approx 25mm is mentioned. There is no need of tight tolerance.
