2. an electrical resistivity of 2 × 10–4 ohm cm or more.
3. An electrical resistivity of 2 × 10-4 ohm cm or more.
4. An electrical resistivity of 2 × 10–4 ohm cm or more.
5. "Bulk electrical conductivity" and "sheet (surface) resistivity" should be determined using ASTM D-257 or national equivalents.
6. ‘Diodes, transistors and similar semiconductor devices’ are semiconductor devices the operation of which depends on variations in resistivity on the application of an electric field.
7. cntrinsically conductive polymeric materials with a "bulk electrical conductivity" exceeding 10000 S/m (Siemens per metre) or a "sheet (surface) resistivity" of less than 100 ohms/square, based on any of the following polymers:
8. In principle, calibration is carried out using dry air (taking into account atmospheric pressure) and extremely pure water (twice distilled and/or micro-filtered with extremely high resistivity > 18 MΩ).
9. The inspection body may, in accordance with the Code for Fire Test Procedures, prescribe a test on a sample partition in order to ensure compliance with the provisions of paragraph 2 on resistivity and temperature increase.’
