Overview of measurement in accordance with ASTM-D257 & IEC 60093 Standards
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Validating the specifications, value and safety of your raw materials, products and assets. Formally confirming that your products and services meet all trusted external and internal standards. Surface resistivity is the resistance to leakage current along the surface of an insulating material.
Volume resistivity is the resistance to leakage current through the body of an insulating material.
A standard size specimen is placed between two electrodes. For sixty seconds, a voltage is applied and the resistance is measured. Surface or volume resistivity is calculated, and apparent value is given 60 seconds electrification time. A 4-inch disk is preferable, or a 4-inch square.
Minimum size is a 3. Surface and Volume resistivity are calculated.
Surface Resistivity, Volume Resistivity, ASTM D257, IEC 62631-3-1
Surface Resistivity is expressed in ohms per square Volume Resistivity is expressed in ohms – cm. Standards can be obtained from appropriate standard authorities.
