In various material tests such as appearance, color, pH value and density tests, physical or performance properties are generally determined in terms of safety, strength, impact resistance and many other qualities. For example, compression tests determine the ability of a material to withstand continuous or gradual load. Before the material collapses or breaks, it is subjected to the compression force and the maximum load it can withstand.

In tensile tests, various stress ratios are applied to the specimen to determine the elongation values, ultimate strength, and reduction in cross-sectional area of the material. In bending tests, the amount of force required to bend the material sample under a three- or four-point loading condition is determined.
Material appearance is especially important in applications where properties such as color, texture, gloss or translucency are of interest. Such perceptual features from physical assets are evaluated with appearance tests.
pH measurements are performed for both acidic and basic solutions. The pH value is a measure of a material's acidity. Generally, the pH value ranges from 0 to 14. A pH value less than 7 indicates that the solution is acidic, a pH greater than 7 indicates it is basic, and a pH of 7 indicates it is neutral.
Measuring the density of a material is an important quality parameter for both raw materials and finished products. Density of solid, viscous and liquid materials is determined by various methods.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. Physical tests (appearance, color, pH value and density tests) are among the numerous tests performed in this context.
