DRK106 Horizontal Board Stiffness Tester

Product Introduction

DRK106 Horizontal Board Stiffness Tester is an instrument for detecting the bending strength of paper, cardboard and other low-strength sheet non-metallic materials.

Technical Standard；

GB/T2679.3：   "paper and paperboard stiffness test",

ISO249. 3： "Determination of paper and cardboard stiffness", the measuring principle of the instrument meets the requirements of

ISO 5628：  "paper and paperboard - static bending stiffness measurement - general principle", and is applicable to other types of paperboard measurement.”

TAPPI T556:  “Applies to measure the bending resistance of paper and paperboard in the machine and cross machine directions.”

Product Application

Generally 20 mN—10000mN

Paper and cardboard are also suitable for some materials with high stiffness.

Technical Parameters

• Measurement range: bending force ( 20-10000mN, resolution 1 mN)
• The indication accuracy is less than 50 mN (+0.6 mN), and the other (+1%) indication variability is less than 1%.
• The bending length is (50 + 0.1) mm, (25 + 0.1) mm, (10 + 0.1) mm.
• Bending angle 15_+0.3_, 7.5_+0.3_
• Bending rate (200±20) °/min (adjustable)

 Working Environment

 Temperature ：20ºC

 Power supply: AC220V±5%, 50Hz, the power supply should be grounded reliably. If   the power supply voltage fluctuates beyond the above range, a power regulator should be used. The working environment is clean, there is no strong magnetic field vibration source, and the worktable is flat and stable.
