Impact Testing

Small Ball Tester
The Small Ball Impact Tester is used to measure the resistance of impact on laminated surfaces by the minimum impact force needed to cause visible damage to the surface under test.

The testing examines the surface testing for damages present of fine hairline cracks , continuous cracks, and flaking of the surface layer.

Large Ball Tester
The Large Ball Impact Tester is used to measure the resistance of impact on surfaces using a large diameter ball. This is defined as the maximum height for which no visible surface cracking, or imprint greater than the specified diameter, occurs in five successive strikes.

The testing examines the surface of the specimen for damage at point of impact. If cracking is not evident, or the carbon imprint is not greater than 0.40” diameter, lower the electromagnetic 2” until cracking is evident. The test should be as close to the center of the specimen as possible.

Swelling and Thickness Testing

Thickness-Measures the boards of the extreme edges at the six points indicated below. Place the specimens in 2” (50mm) water bath. Remove the test specimen after 24h ±26min and dry with a towel dry. Determines the final thickness of extreme edge at the same measuring points.

Abrasion Testing

Resistance to Surface Wear
This test measures the ability of the decorative surface of the laminate under test to resist abrasive wear through the sub-level. Abrasion is achieved by rotating a specimen in contact with a pair of loaded cylindrical wheels covered with abrasive paper. The wheels are positioned so that their cylindrical faces are equidistant from the specimen’s axis of rotation but not tangential to it . As they turned by the rotating specimen they abrade an annular track of the specimens surface. The number of revolutions of the specimen required to cause defined degrees of abrasion are used measures of resistances to surface wear.

HPLC Analysis

HPLC Analysis is used to separate, identify and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components leading to the separation of the components as they flow out the column. The components are then detected using a UV-Vis Spectra Detector.
