National foreword This British Standard is the official English language version of EN 50290-2-30:2002. The UK participation in its preparation was entrusted by Technical Committee EPL/46, Cables, wires and waveguide, RF connectors and accessories for communication and signalling, to Subcommittee EPL/46/1, Communication cables, which has the responsibility to: —
aid enquirers to understand the text;
—
present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;
—
monitor related international and European developments a nd promulgate them in the UK.
A list of organizations represented on this subcommittee can be obta ined on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all th e necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
This British Standard, having been prepared under the direction of the Electrotechnical Sector Policy and Strategy Committee, was published under the authority of the Standards Policy and Strategy Committee on 22 March 2002

(normative) Volume resistivity
This test shall be made on insulated conductor sample. The sample shall be immersed in water previously heated to the specified temperature, a length of about 0,25 m at each end of the sample being kept above the water. A DC voltage of between 80 V and 500 V shall be then applied between the conductor and the water. The insulation resistance shall be measured 1 min after application of the voltage. The volume resistivity shall be calculated from the measured insulation resistance by the following formula : r =
