1. RCA Norman Abrasion Tester
The RCA Norman Abrasion Tester is used to test surfaces for resistance to abrasion and wear. Typically used on painted or plated organic finishes, foil, and inked key pad lettering. This tester is widely used as a standard for many silicone key pad and membrane switch manufacturer. This abrader is used as a standard to the auto, appliance, cell phone, plastics, and coating industries. It uses an inexpensive roll of throw away abrasion paper.
2. Slippery Tester
Rough surfaces often wear out more quickly than smoother surfaces. A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material.
3. Contact Angle
Contact angle allow direct measurements of surface tension, interfacial tension and contact angles. It is an extremely versatile technique used for characterization of both liquids and solids.
4. Fourier Transform Infrared (FTIR)
It has brought a revolution in the world of Infrared technology, as it follows an efficient method-giving accurate results. Substituting the conventional methods and the older technology, FTIR spectrometer has made infrared experiments easier.
It is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by colour compounds. It uses photometers, known as spectrophotometers, that can measure a light beam’s intensity as a function of its colour (wavelength). Important features of spectrophotometers are spectral bandwidth (the range of colours it can transmit through the test sample), the percentage of sample-transmission, the logarithmic range of sample-absorption, and sometimes a percentage of reflectance measurement.
6. Atomic Force Microscope (AFM)
AFM is a type of scanning probe microscopy (SPM), with demonstrated resolution on the order of the fractions of a nanometre, more than 1000 times better than the optical diffraction limit. The information is gathered by “feeling” or “touching” the surface with a mechanical probe. Piezoelectric elements that facilitate tiny but accurate and precise movements on command enable precise scanning.
7. Pendulum Hardness Tester
It is a devise used for measuring hardness of materials. The instrument consists of a pendulum which Is free to swing on two balls resting on a coated test panel. The pendulum hardness test is based on the principle that the amplitude of the pendulum’s oscillation will decrease more quickly when supported on a softer surface. The hardness of any given coating is given by the number of oscillations made by the pendulum within the specified limited of amplitude determined by accurately positioned photo sensors.
8. Linear Abrasion Tester
It offers the operator perhaps the greatest versatility of commercially available testers and can be utilized on many manufactured goods. Developed to test actual products, the apparatus incorporates a horizontal arm that reciprocates in a linear motion. Attached to the end of the arm is a ‘free-floating’ test system that is placed onto the specimen at the start of the test.
9. Pencil Hardness Tester
A test used to evaluate the hardness of a soft material such as a coating. A set of pencils of varying grades of hardness are sharpened to a point. Starting with the softest, each pencil is drawn across the surface to be tested. The test results are hardness of the hardest pencil that does not scratch the surface. This test has many variables that cannot be easily controlled such as pressure and pencil angle. Thus, it should just be used for a rough comparison of materials.
10. Cross Cut Tester
It is a method for determining the resistance of paints and coatings to separation from substrates by utilizing a tool to cut a right-angle lattice pattern into the coating, penetrating all the way to the substrate.
A quick pass/fail test can be accomplished through this method. When testing a multi-coat system, determination of the resistance to separation of different layers from one another can be accomplished.
11. Moisture Analyzer
A moisture analyzer determines the moisture content of a sample with the loss on drying method and consists of a weighing and heating unit (infrared).
12. Melt Flow Index
It is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures.
13. Polarize Stress Checker
14. Water Bath
A water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. All water baths have a digital or an analogue interface to allow users to set a desired temperature.
