Dielectric and resistive properties of solid insulating materials - Determination of resistive properties (DC Methods). Surface resistance and surface resistivity1 Scope This part of IEC 62631 covers methods of test for the determination of surface resistance and surface resistivity of electrical insulation materials by applying DC voltage. A Commented Version (CMV) of this standard is available here. Please note, the CMV of the standard is not adopted, and therefore doesnt contain an additional national foreword, or national annex that might be contained in the BS adoption of the standard. However the IEC

It is limited to the following cases:

BS EN 15802 discusses the conservation of the cultural property

and on lateral and longitudinal continuity rather than on vertical continuity which is difficult to measure

BS EN 14726:2019 supersedes BS EN 14726:2005

Manufacturers of screen terminating devices

The document is not aimed at defining new parameters for the general evaluation of the accuracy of CMM measurements

BS EN IEC 61281‑1:2018 includes a technical change with respect to BS EN 61281‑1:1999:

human-based products such as crew or operators

Static test pressure shall be 1

BS 6263-2:1991 supersedes BS 6263-2:1982
