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 and
promulgate them in the UK.
A list of organizations represented on this subcommittee can be obtained on
request to its secretary.

This European Standard was approved by CENELEC on 2001-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

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
