The amount of water absorbed by any paper is dependent on various characteristics such as its sizing and porosity etc. The sizing of paper can be determined by conducting a water absorption test with the help of a COBB Tester.
In this test the weight of water absorbed by a known area of the paper under test in a specified duration of time is determined, from which the sizing characteristic is evaluated. However, this method is not recommended for determination of sizing characteristic of writing paper.

Tensile strength and elongation are the two most important properties that determine the suitability of any material for a particular application. These properties are determined with the help of a tensile testing machine. The load range and rate of elongation are selected depending on the characteristics of the materials being tested. The GLOBE Digital Paper Tensile Testing Machine is suitable for determining tensile strength and elongation of paper and similar materials. It is based on constant rate of traverse principle, in which one end of the test specimen is held in a clamp attached to load measuring device and the other end is held in a clamp which is made to move at a fixed selectable speed with the help of an inverter driven motor, worm reduction gear box, and screw arrangement.
Compression Strength Tester
|Capacity||10 KN, 2 KN, 50 KN|
|Weight||150 Kg or 160 Kg|
Standard: ASTM D 642-1994
|Maximum Compression Load||1000 Kg|
|Pressure Gauges||0 - 42 kg / cm2 For Testing Upto 160 kg|
Paper tubes used for winding yarn, shall have adequate mechanical strength. One of the tests used for ascertaining the mechanical strength of paper tubes is the collapse test. In this test, a test specimen taken from the sample of paper tube is placed on a rigid flat metallic plate and pressed against another rigid flat metallic plate. The maximum force required to collapse the tube is then measured.
Paper Thickness Gauge
|Measuring Range||0 - 10 x 0.01 mm|
|Diameter of Pressure Foot||15 mm|
|Diameter of Anvil||45 mm|
|Depth of Neck||100 mm|
|Pressure Exerted by Indenter||1 +- 0.1 kg/cm2|
The standard thickness of any sample of paper or paper board is measured by placing one or more test specimens taken from the sample under test on a flat anvil and pressing it down with the help of a circular indenter applying a pressure of 1 ± 0.1 kg/cm2 on the test specimen. The diameter of indenter used for measuring the thickness is between 14 and 16.5 mm, while the pressure is applied by means of a dead weight to give more consistent readings.

Quadrant Balance For GSM
The weight per unit area or grammage of any material in form of sheets is usually expressed as its GSM, that is its weight in grams per square meter of its area. It is one of the most important parameters to determine the quality of any paper.
In addition to paper, it can also be used for evaluation of grammage of fabrics, coated fabrics, felt, plastic films and sheets, etc.
Different models with single and dual range scales given below are available:
- Scale A: 0-160x0.5 GSM (sample size 25x25 cm)
- Scale B: 0-1000x4 GSM (sample size 10x10 cm)
- Scale A: 0-300x1 GSM (sample size 20x25 cm)
- Scale B: 0-600x2 GSM (sample size 20x12.5 cm)
