Direct Answer: The ZDT Tester XP2 Series measures Z‑Directional Tensile (ZDT) strength of paper and paperboard per ISO 15754, TAPPI T541, and Standard D.37P specifications.

What is the ZDT Tester?

The ZDT Tester XP2 Series is designed for the Z‑Directional Tensile Test of paper and board products, quantifying strength in the thickness direction. It ensures reliable evaluation of bonding and internal fiber strength critical to paper performance.

Which standards does it support?

• ISO 15754
• TAPPI T541
• Standard D.37P Specifications

How does it work?

The instrument clamps paper or board specimens and applies tensile force in the Z‑direction until failure. The LCD display provides real‑time force readings, including maximum peak force, average force, standard deviation, and coefficient of variation (COV).

Key features

• Large LCD display with easy‑to‑read numbers
• Calibration directly from LCD panel in lb, kg, or N
• Displays maximum peak force, average force, SD, and COV during test
• Precision machined components for durability and accuracy
• Simple operation and minimal maintenance required

Service and support

DEK‑TRON provides full support, including maintenance, replacement parts, and technical service directly from the factory.

Typical applications

Quality control and R&D testing of paper and paperboard products, ensuring fiber bonding strength and performance in packaging, printing, and converting industries.

FAQs

What does the ZDT Tester measure?
It measures Z‑directional tensile strength, reflecting internal bonding of paper and board.

What results are displayed?
Maximum force, average force, standard deviation, and coefficient of variation (COV).

How is calibration performed?
Calibration is performed quickly via the LCD interface in lb, kg, or N units.
