AWS D1.1 thickness range

[jayager]

When i was reviewing a AWS D1.1 WPS/PQR the test coupon is a plate 25mm.
But the range mentioned is 25mm to Unlimited. But when i refer code book 2000 in that it was 1/8 - Unlimited.
Please guide me in any new version they changed the range.

It's not a code change.

Either a manufacturer error WRT the range, or the manufacturer decided to make the minimum WPS thickness range more stringent than required by D1.1, which is allowable. The primary drawback to this is that they are bound by the more rigorous, self imposed conditions, if this is the case...
