scope:

This part of IEC 60794 is a family specification that covers gas pipe cables and subducts for installation by blowing and/or pulling/dragging in high pressure gas pipes (400 mbar to 4 bar). Systems built with components covered by this standard are subject to the requirements of sectional specification IEC 60794-3.

Gas pipe cable and subduct constructions have to meet the different requirements of the gascompanies and/or associations regarding chemical, environmental, operational interactions and in general maintenance conditions.

I/O-ports for the inlet and outlet of the gas pipe cables and/or subducts are housing the sealing system assuring the absolute gas tightness preventing any gas leakage due to the installation of the gas pipe cables into the gas pipes.

A table of preferential applications, describing gas pipe cable characteristics versus methods of installation is reported in Annex A for high pressure gas pipe cables.

Clause 4 describes a blank detail specification for gas pipe cables and subducts for installation by blowing and/or pulling/dragging in high pressure gas pipes. It incorporates some minimum requirements.

Detail specifications may be prepared on the basis of this family specification.

The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria should be interpreted with respect to this consideration.

The number of fibres tested is representative of the gas pipe cable and should be agreed between the customer and the supplier.
