Crush Tester

The Labo Crush Tester has a built-in industrial PC and displays Crush Curves and results on the well-arranged touchscreen.

Labo Crush Tester has many special features to make measurement easier.The instrument can memorised the measurement starting positions and has self resetting function ,which makes the operation very easily. After the measurement, the calculated test result is indicated directly on the display with the correct units.

Features

Touchscreen for convenient control.

Graphic display of Crush value curve

and statisticMenus allow programming

to meet pre-deﬁned test methods and

international standards.

Accuracy: ±0.5% of the display range

Data Outputs: RS232, WIFI, Parallel Print Port

Optional: Labo-DMS Connect（Labo Data Managenent System）

RCT – Ring Crush Test : A sample of paper or cardboard is placed in a ring formation and subjected to a successively increasing edge compression force until it breaks,then the resistance force is measured. The RCT value is the force divided by the sample's length.

Applicable standards：APPITA/AS 1301.407s, PAPTAC D.33P, DIN 53134, ISO 12192, JIS P8126, SCAN P 34, TAPPI T 822

CLT – Concora Liner Test measures the same way as RCT, but is carried out in another type of sample holder.

CCT – Corrugated Crush Test: A sample is corrugated between heated corrugating rolls. The sample is fixed in a special jig that is adapted to the corrugated shape. The crushing force is applied and measured parallel to the top of the corrugating medium. The CCT value is the maximal force that the sample can withstand before it breaks.

Applicable standards：SCAN P 42, TAPPI T 843

CMT – Concora Medium Test: A sample is corrugated between heated corrugating rolls. The flute is fixed and held together by a pressure-sensitive tape, so that single-sided corrugated board is imitated. The crushing force is applied vertically to the paper ,then the breaking force is measured. The CMT value is the maximal force the sample can withstand before it breaks.

Applicable standards：APPITA/AS 1301.434s, PAPTAC D.24P, DIN 53143, EN ISO 7263, ISO 7263, SCAN P 27, TAPPI T 809

ECT – Edge Crush Test: A sample of corrugated board is subjected to increasing force, parallel to the flutes, until it breaks. The ECT value is the breaking force divided by the sample's width.

Applicable standards：APPITA/AS 1301.444s, DIN 53149, EN ISO 3037, FEFCO No.8, ISO 3037, ISO 13821, SCAN P 33, TAPPI T 811, T 823,T 838, T 839

FCT – Flat Crush Test : A sample of corrugated board is subjected to vertical increasing force until the fluting breaks. The FCT value is the force divided by the sample’s surface area.

Flat Crush Hardness – A measurement of the corrugated board’s yield point in a FCT sample. Equivalent to the first ‘peak’.

Flat Crush Energy – The total energy absorbed during a FCT measurement.

Applicable standards：APPITA/AS 1301.429s, EN 23035, FEFCO No.6, ISO, 3035, SCAN P 32, TAPPI T 825

PAT – Pin Adhesion Test. Adhesion resistance is the maximum force required to separate the linerboard from the fluting with the help of a special sample holder.

Applicable standards：APPITA/AS 1301.430s, TAPPI T 821

SQT – Score Quality Test:A sample is placed on a U-shaped support and pressed by a thin strip, exactly above a score, until it breaks. The ratio between the scored and un-scored values gives the score ratio.

Applicable standards：TAPPI T 829
