Optical fibre cables - Gas pipe cables - Family specification for cables to be installed in high pressure gas pipes

Asnjë informacion i shtuar.

This document is a family specification that covers gas pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in high pressure gas pipes. Systems built with components covered by this standard are subject to the requirements of sectional specifications EN 60794-3 and EN 60794-4 where applicable. Gas pipe cable and sub-duct constructions have to meet the different requirements of the gas-companies and/or associations regarding chemical, environmental, operational interactions and in general maintenance conditions. 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 sub-ducts for installation by blowing and/or pulling / dragging in/into 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 sewer cable and should be agreed between the customer and supplier.
