Overview of measurement in accordance with ASTM-D257 & IEC 60093 Standards
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. For sixty seconds, a voltage is applied and the resistance is measured.
Auditing Consulting Sourcing Training. Surface resistivity is the resistance to leakage current along the surface of an insulating material. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions lec a wide range of industries around the world. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Assurance Testing Inspection Certification.
For measuring the surface resistance, the resistance is measured between the upper electrode and an annular electrode dln is close by whereas the lower electrode is on the ground. Validating the specifications, value and safety of your raw materials, products and assets. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Volume resistivity is the resistance to leakage current through the body of an insulating material. Methods of test for insulating materials for electrical purposes — Volume resistivity and surface resistivity of solid electrical insulating materials withdrawn DIN EN A standard size specimen is placed between two electrodes. In addition, it may be relevant to evaluate the feasibility of cin discharge that correlates directly with the surface resistance. Sample Preparation Air conditioning: Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

Results Specific surface resistance Surface resistance Specific volume resistance Volume resistance. Dielectric and resistive properties of solid insulating materials — Part Surface Resistivity is expressed in ohms per square Volume Resistivity is expressed in ohms – cm.
Formally confirming that your products and services meet all trusted external and internal standards. Send us a request Wilton UK: Minimum size is a 3.

Send us a request Need help or have a question? A 4-inch disk is preferable, or a 4-inch square. Surface and Volume resistivity are calculated. To determine the surface resistance and the volume resistance, a specimen is put on the lower electrode and the electrical resistance between two electrodes is measured.
Surface Resistivity, Volume Resistivity, ASTM D257, IEC 62631-3-1
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Certification Formally confirming that your products and services meet all trusted external and internal standards. The determination of the surface resistance and the volume resistance is used for materials that have sin separate electrical equipment. Surface or volume resistivity is calculated, and apparent value is given 60 seconds electrification time.
Standards can be obtained from appropriate standard authorities. Inspection Validating the specifications, value and safety of your raw materials, products and assets. For the volume resistance, the measurement is made between the upper and the lower electrode.
