Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Send us a request Wilton UK: Surface or volume resistivity is calculated, and apparent value is given 60 seconds electrification time. Sample Preparation Air conditioning: Surface and Volume resistivity are calculated.
Surface resistivity is the resistance to leakage current along the surface of an insulating material. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Surface Resistivity, Volume Resistivity, ASTM D257, IEC 62631-3-1
Dielectric and resistive properties of solid insulating materials — Part Surface Resistivity is expressed in ohms per square Volume Resistivity is expressed in ohms – cm.

Overview of measurement in accordance with ASTM-D257 & IEC 60093 Standards
For sixty seconds, a voltage is applied and the resistance is measured. The determination of the surface resistance and the volume resistance is used for materials that have to separate electrical equipment. For measuring the surface resistance, the dln is measured between the upper electrode and an annular isc that is close by whereas the lower electrode is on the ground. Assurance Testing Inspection Certification. In addition, it may be relevant to evaluate the feasibility of the discharge that correlates directly with the surface resistance.
For the volume resistance, the measurement is made between the upper and the lower electrode. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
