The method Glass Screen Wear Resistance Testing

Due to the property of being optically transparent, glass is widely used in a variety of products, such as windows, containers, optical lenses, mirrors and countless others. During the manufacturing process, glass can be formed into different shapes, ranging from flat sheets to highly intricate shap...


Widely Applied Scratch Test

The scratch test has become one of the most widely applied methods to evaluate coating adhesion at present. Over the past two decades, this technique is extensively used to assess the adhesion of PVD/CVDdeposited superhard nanocomposite coatings, which usually exhibit a high residual stress at the c...



A new scratch test methodology is developed here. Different test conditions are used in conducting the scratch tests. The results is compared and assessed to determine the best method. Results from a concurrent study using finite element analysis (FEA) will also be presented. Model Material System a...



The great attention paid on aesthetics of polymer surfaces in recent years has led to significant interests in the scratch resistance and visibility of polymers. To this end, reliable methods to quantify scratch resistance and visibility become the top priority. The methods used in the quantificatio...


The Trendency Of Current Testing Instruments Industry

Along with the development of science and technology now, instrument and meter industry in the development by leaps and bounds, coupled with the current progress and development of computer technology, network technology, to form a network and a practical monitoring system, can improve the productio...


Test Method for Abrasion Resistance of Organic Coatings

ASTM D406-This test method covers the determination of the resistance of organic coatings to abrasion produced by the Taber Abraser on coatings applied to a plane, rigid surface, such as a metal panel. This standard does not purport to address all of the safety concerns, if any, associated with its ...


Flammability of Polymers test

Most plastics are carbon-based materials and will burn and give off gases and smoke when subjected to a flame. Plastics are excellent fuels but are generally classed as ordinary combustibles and fall into the same category as wood, leather and many other common materials. All of these materials will...


Operating Method of Oxygen Index tester

This method describes a procedure for determining the relative flammability of organic films and reinforced composites by measuring the minimum concentration of oxygen in a gaseous mixture of oxygen and nitrogen that will just support combustion. It is based on ASTM Standard D2863-77 but modified to...


Test method for Fogging Tester

The term Fogging refers to the film that collects on the inside of vehicle window glass. Of particular interest is the windshield, because this film can both limit light transmittal as well as refract the light that is transmitted, impairing visibility and creating safety concerns. A fogging test sy...
