Testing Products for ASTM D348
APP-D348Rigid Tubes Used for Electrical Insulation. Covers axial tension and crushing strength.
Application Insight:
Requires internal mandrels for tension testing to prevent tube collapse in the grips.
Pro Tip:
Mandrels: Ensure mandrels are a slip-fit to avoid pre-stressing the tube before the test starts.

Implementation Commentary
Characterizes the mechanical durability of insulating sleeves. The Crushing Strength is a key indicator of resistance to installation damage.
Common Pitfalls
Grip slippage due to the smooth surface of the insulating polymer; use serrated V-jaws.
