Antistatic Tests

Antistatic Tests

Our laboratory performs the testing, measurement and control of the anti-static properties of the materials.

EUROLAB helps customers understand the anti-static properties of materials. This information is very important in many applications, as the accumulation of static loads can lead to dangerous or problematic electrical discharges.

The ability of a material to discharge and thus damage electrical charges is influenced by the purity of the material, the level of contamination, the moisture content, the physical form (including surface roughness) and other factors. For critical applications, it is important to make an appropriate assessment of these static properties, rather than relying entirely on theoretical material properties.

EUROLAB offers test methods for evaluating the anti-static properties of materials. Measurements are typically performed on solids.

Static properties test measurements:

Volume Resistivity is a measure of the bulk electrical properties of the material, but it is not a particularly good antistatic performance indicator where surface effects or inhomogeneous contamination may prevail.

Surface Resistivity is more commonly used to evaluate antistatic properties, but the results can be relatively misleading - for example, if a relatively conductive polymer sheet has a thin insulating surface layer.

  • Packing materials for electronic components
  • Polymer film production problems
  • Polymer film and sheet processing problems (adhesion and binding)
  • Dust handling and ignition analysis

Electrical Properties of Polymers

The electrical properties of plastics and polymer materials have been tested to certain standards for industries such as aerospace and construction products.

The electrical properties of polymers, elastomers, composites and plastic films are essential for a wide range of industries such as automotive, aerospace, construction products, marine, packaging and consumer goods.

Electrical tests are generally measurements of resistance, conductivity, or load storage, either on the surface or on the plastic material.

Various factors, such as dielectric strength plus volume and surface resistance, are very important to measure the structure of the polymer material, especially in terms of yield and conductivity.

Anti-static Properties of Polymers

  • Dielectric Constant / Dispersion Factor ASTM D150, IEC 60250
  • Dielectric Strength ASTM D149, IEC 243-1, IEC 60243
  • Volume Resistance ASTM D257, IEC 60093
  • Surface Resistance ASTM D257, IEC 60093

In addition to the standard electrical tests, Intertek performs many special variations of these electrical tests required by the complex engineering applications of the plastics, elastomer, composite and film industries.

Anti-static properties of textiles

People; friction during walking and sitting, getting up and down the vehicles, working at the table, wearing clothes and so on. During daily activities such as (+) or (-) are charged with electric charge and often experience a feeling of distortion. All these formations are the discharge of electrostatic charge accumulated on human. In the researches, antistatic applications have started to be done in order to discharge the load safely and to protect the people and sensitive devices / objects sensitive to static electricity.

In order to measure static electricity charge;

EUROLAB has started to apply the following test methods in carpet textiles and flooring products.

  • ISO 6356.
  • TS EN 1815 / EN 1815
  • TS ISO 10965 / ISO 10965

You can have tests to determine the antistatic properties of metal, wood, polymer or textiles in our laboratory.
