Physical Testing
LIB offers a wide variety of physical testing, evaluation and measurement services at its Florida and German facilities, including color, gloss, mechanical testing, and much more.
Quantify Your Exposure Testing Results
It is important to quantify the results of any exposure testing program. Typically, customers are interested in the amount of change their material experiences during the exposure. Change in some properties, like color or gloss, can be measured with specialized optical measurement instruments. Change in other physical properties can be measured with mechanical testing. Other changes like cracking, peeling, chalking, blistering, or rusting can be evaluated visually and rated according to standard scales.
Visual Evaluations
Visual evaluation reports detail all defects observed, including cracking, blistering, peeling, chalking, adhesion, color change and corrosion. All visual ratings are made under standard lighting conditions to provide accurate, repeatable results.
Examples of visual evaluations (and applicable methods) include:
Chalk - ASTM D4214, ISO 4628-6 Blistering - ASTM D714, ISO 4628-2
Cracking - ASTM D661, ISO 4628-4 Checking - ASTM D660, ISO 4628-4
Flaking/Scaling - ASTM D772, ISO 4628-5 Erosion - ASTM D662
Mold, Mildew, and Fungus - ASTM D3274 Dirt Retention - ASTM D3274
Gray Scale - ASTM D2616, AATCC EP1 Adhesion - ASTM D3359
Corrosion - ASTM D610, ASTM D1654, ISO 4628-3 & -8 Filiform Corrosion - ASTM D2803, ISO 4628-10
