A Choice of Lamps for the QUV Accelerated Weathering Tester

Your exposure application determines which type of UV lamps should be used. All of the QUV® accelerated weathering tester’s lamps emit mainly ultraviolet rather than visible or infrared light. All are electrically equivalent to an ordinary 40-watt fluorescent. However, each lamp type differs in the total amount of UV energy emitted and in its wavelength … Read more

The summary of Martindale method for testing the abrasion resistance of fabrics

The abrasion resistance of textiles refers to the wear resistance between fabrics or between fabrics and other substances during repeated friction. There are various methods for testing the abrasion resistance of textiles, such as the flat abrasion method, the curved abrasion method, the folded edge abrasion method, and the compound abrasion method. The Martindale method … Read more

Condensation test

Water is a common enemy to most materials.  It causes metals to corrode, organics to decompose, and structures to disintegrate. Condensation is water that has been distilled from impure water, mixed with the atmosphere, and saturated with oxygen.  This type of moisture has also been called “aggressive water”, because it carries oxygen with it as … Read more

It can also clog feed lines or spray nozzles, as well as cause other problems related to test reliability. A reliable … Read more

Additives & Colorants

Colorants and other additives that see sunlight, moisture, and heat are subject to the damaging forces of nature. Of course, some additives are formulated specifically to protect base polymers against forces of weathering and corrosion. Accurate simulation of the short-wave ultraviolet portion of sunlight and outdoor moisture in a UV accelerated weathering tester is widely … Read more
