W-PT-DB Test Bar with Artificial Defects
The W-PT-DB is identical to the Standard Stackable W-PT Pull Test Bar, however artificial defects have been introduced. The artificial defects are represented by a circle in the center of the bar and a transverse notch toward one end. The circle is produced by the press fit of a 3/8” (9.5mm) Diameter Plug into the hole in the center of the bar, thus the W-PT-DB is not stackable. The transverse notch is approximately 0.016” Wide x 0.032” Deep (0.41mm x 0.81mm), is Epoxy filled, and extends the width of the Bar The Notch is positioned 2 ½” (63.5mm) from the one end of the bar, to allow either indication to be used. The W-PT-DB is an excellent training and demonstration fixture, and ensures the 10 Pound Pull Test for AC Yokes.
