KRK short spann compression tester
Physical testing / Crush
  • No.2093
  • [JIS]P8156-2012
  • [TAPPI]
  • [ISO]9895
本機はショートスパン型の圧縮試験機です。巾15mm 長さ70mmに切り抜いた試料を測定部にセットし、わずか0.7mmのスパンで試料をクランプし圧縮強度を測定します。  測定結果は圧縮荷重及び単位巾当りに換算した圧縮強さを表示します。また、圧縮状況の変化をグラフ表示します。  測定サンプルの坪量を入力しますと集計の際に圧縮係数(Compression index)N・m/gを表示します。

This tester measures compression strength of liners, corrugated mediums, corrugated board and small-sized containers. It determines resistance against compression in various forms. It is designed for simplified measurement of compression strength, and a load cell is employed for load detection, achieving accuracy and reproducibility.
Column compressor (end crush tester)
Physical testing / Crush
  • No.2097
  • [JIS]Z-0401-1985
  • [TAPPI]
  • [ISO]3035
This tester measures the vertical compression strength of a corrugated board sheet, and is also referred to as an end crush tester. A corrugated board sheet is erected straight and load is applied on it. As the load increases, the maximum load is measured that is reached before the side surfaces of the corrugated board sheet is buckled. The strength perpendicular to the corrugated section is a characteristic value correlated to the pressure-withstanding capacity of the corrugated board case and also has a correlation with the ring crush characteristic of the raw paper. Measurement is performed on a specimen collected with a cutter for end crush tests (No. 2134) that is set into a crush tester along with this attachment.
Ply bond tester (pin adhesion tester)
Physical testing / Crush
  • No.2098
  • [JIS]Z-0402-1995
  • [TAPPI]T-821
  • [ISO]
In double-faced corrugated board, two liners are securely bonded to the corrugated medium, providing the strength of a structure. This adhesive strength is tested as follows. Two pin apparatuses are inserted between threads of the corrugated medium and the liner. One of the pin apparatuses is inserted from one side, and the other, from the opposite side, forming a U shape, on both sides of the specimen. This specimen is set onto the crush tester's compression plate to read the value of the adhesive strength. This is referred to as the double-faced pin adhesion test method, and you can observe that the pin apparatus on the side with weaker adhesion strength comes off first. In the single-faced pin adhesion test method, every other pin on a pin apparatus is inserted between a flute and the liner to measure adhesion strength.
