Test Tools for Paper and Cardboard

We have developed special test tools for many important standards in the paper and cardboard industry. Here you can find a small selection for: compression/compression crush tests, determination of the bursting strength, puncture tests, flexure tests, friction tests, etc. 

Test device for determining the short span compression strength

Applications: 

  • Tests to determine the short-span compressive strength at the sheet level of paper and cardboard (100 to 400 g/m²) to ISO 9895, TAPPI T826 and DIN 54518.

Function description: 

  • The test device is used to determine the short span compression strength of paper and cardboard. It consists of two pneumatic clamping units. These are connected to one another by two precision guides.
  • The line of action of force of the guide element in the specimen and the symmetry line of the load cell are in one plane. They permit end loading without lateral forces and bending moments.

Advantages: 

  • Used in combination with burst pressure instrument and materials testing machines: very functional and cost-effective, especially when testing corrugated base paper.
  • Cost-effective accessories for testing machines instead of expensive individual solutions.
  • Solid construction with precision guides for excellent reproducibility, even with heavy paper grades.
  • Guides and line of action of force in one plane; specimen loading is symmetrical and free from bending moments, delivering premium quality results for the SCT value.
  • ZwickRoell test programs with prepared data interface to CAQ systems, guaranteeing rapid data integration.
  • Pairs of jaws featuring precision vertical and horizontal guidance.
  • Pneumatically applied closing force.
  • Can only be operated via PC-controlled testing system.

Ring crush test device (RCT)

  • Applications: Tests to DIN 53134 (withdrawn), ISO 12192, and TAPPI T 822
  • Function description: The ring crush test device (RCT) consists of a base plate (bottom part) and nine discs (upper part). The base plate has a tangential insertion slot.

    The specimen is pushed into the free gap between the ring of the base plate and the inserted disc.

Compression test device (FCT, ECT)

Applications: 

  • Determination of flat crush resistance (FCT) of single-faced and single-wall corrugated board to ISO 3035, EN 23035, and TAPPI T 825
  • Determination of edge crush resistance (ECT) of corrugated board to DIN EN ISO 3037 and TAPPI T 811
  • Determination of flat crush resistance of corrugated board via CMT test to DIN EN ISO 7263 and TAPPI T 809
  • Determination of ring crush resistance (RCT) of paper and board to DIN 53134 (withdrawn), ISO 12192 and TAPPI T 822 (requires ring crush test device, Item No. 316243)

Function description: 

  • The compression test kit consists of a lower and an upper compression platen with guide blocks. The test material is placed between these compression platens and compressed by the compression platens.

Determination of the bursting strength

Applications: 

  • Testing paper to ISO 2758 (Item No. 057817)
  • Determination of bursting strength of solid and corrugated board and the papers used for them for tests to DIN 53141 Part 1 and ISO 2759 (Item No. 057819)

Function description: 

  • The hydraulic actuator is used to generate pressure. It is mounted in the testing system. The volume flow can be steplessly adjusted by changing the crosshead speed. The hydraulic actuator is connected to the burst device via a high pressure hose. Pressure is measured electronically using a strain gauge sensor.
  • A pneumatic actuator is integrated in the burst device. It is used to clamp the specimen between the compression platen and the pressure chamber. The moving crosshead presses against the hydraulic actuator during the test, whereby a volume of liquid is pressed into the pressure chamber. The resulting, increasing pressure causes the rubber membrane to arch. The rubber membrane then presses against the specimen until it breaks.

Puncture tests

Applications: 

  • Testing to DIN 53142-2

Function description: 

  • The puncture fixture is used to determine the resistance that a gripped specimen presents when penetrating a puncture body.

Advantages: 

  • Clamping via spring force (see below) according to specimen thickness.
  • Force measurement by means of interchangeable load cell.

Ball puncture test device for tissue products

Applications: 

  • Tests to EN ISO 12625-9

Function description: 

  • The ball puncture test device is used to determine the resistance that a gripped specimen presents when penetrating a puncture body.

Advantages: 

  • Clamping by means of spring force is fast and avoids operator error.
  • The force-deformation behavior is shown as a curve, providing information regarding the ductility of tissue products.
  • Simple assembly and wide measurement range allow tests to be performed on wet materials also.
  • The surface consists of a Vulkolan coating.

Wet tensile test

  • Applications: Wet tensile test to DIN 53112 Part 2, EN 12625-5, ISO 3781 and TAPPI T456
  • Function description: The Finch clamp is installed into the specimen grip. The water bath can be moved vertically.
  • Advantages: Vertically adjustable water bath.

 

Test fixture for Z-direction tensile test on paper

Applications: 

Determine the processability of paper via the internal bond test (z-direction tensile test). In this test to TAPPI T 541 or ISO 15754, the internal fiber bond strength of paper or multi-ply paperboard is determined. We ensure absolute parallelism and transverse stiffness in the fixture, enabling reliable test results in accordance with the standard.

  • Determination of inter-fiber bond strength of paper in the sheet plane.
  • Determination of ply adhesion in the sheet plane of paper or paper-like laminates.

Function description: 

  • Tensile tests at the sheet level allow for the determination of the fiber composite behavior of paper, and the adhesion between layers of multi-layer materials. The test device complies with TAPPI T541 om-99. Tensile tests at the sheet level require a high level of parallelism of the compression platens and secure fastening of the specimen on the specimen carrier. Both criteria are met with the test device for Z-tensile tests. Traverse-bracing and precision-controlled frames allow for a high parallelism of the compression platens. Precision roller guidance for the specimen carriers prevents the need to make adjustments and eliminates excess. The testing fixture allows for the application of a strip of about 150 mm in length for a single operation. Then, when specimen carriers and adhesive tape carriers are pushed in a crisscross movement, five specimens can be tested without having to perform additional specimen preparations.
  • In order to carry out a tensile test at the sheet level, a specimen is taped with an area of 1" x 1" (25.4 mm x 25.4 mm) between two specimen carriers. Double-sided tape is used. During the test, the specimen and the tape are pressed together and then separated. For this reason, the adhesive strength of the tape must be considerably more than the force required to separate the fiber composite. The primary measurements are the maximum force and the separation energy at maximum force.

Advantages:

  • Specimen carriers arranged at 90° to each other enable five individual specimens to be tested in succession with a single application.
  • A leveling element plus high transverse stiffness of the fixture guarantee precise, repeatable test results.
  • Through easy, convenient handling the test practically runs itself.

Save time:

  • Test five individual specimens in succession with a single application
  • Pressing on specimen plus tensile test, in one operation.
  • Optional specimen preparation station makes specimen preparation child's play.

Compressibility testing

  • Applications: For cyclic compression and indentation tests on stiff materials. For compressibility tests on coated paper and membranes. Continuous measurement of force and deformation.
