Perpendicular Verification Devices

Supports the following standards: ASTM C39

PVDs (Perpendicular Verification Devices) are used to quickly and accurately verify cylinder perpendicularity per ASTM C39 when using Econ-o-Pad Capping Pad Sets with test cylinders. Both the 4" x 8" and the 6" x 12" devices are configured to rest against the test cylinder while avoiding contact with your ASTM-compliant top and bottom retaining rings. By resting the base of the device against the lower platen of the compression machine while having the vertical edge against the test cylinder, you can use the included Gap Measuring Tool to verify that there are no gaps between the cylinder and the device indicating the compression test complies with ASTM C39 and can proceed.

Also available is a device designed for use with a 4" high x 7.5" round or square spacer for use when your operation uses this type of spacer in the compression machine.
