Description / Abstract:
This part of ISO 16486 specifies a code of practice dealing with
unplasticized polyamide (PA-U) piping systems, intended to be
buried outside buildings and used for the supply of gaseous fuels.
It addresses the common basic principles for gas supply
systems.
More detailed national standards or codes of practice might
exist in the ISO member countries. This part of ISO 16486 is
intended to be applied in association with those national standards
or codes of practice related to the above-mentioned basic
principles.
It is applicable to mains and service lines, the components of
which are prepared for jointing by scraping and/or machining, and
gives instructions for the design, storage, handling,
transportation, laying conditions and fusion quality control of
PA-U pipes and fittings up to and including 250 mm outside
diameter, as well as subsequent joint testing, backfilling, pipe
system testing, commissioning and decommissioning.
The jointing methods covered by this part of ISO 16486 are butt
fusion jointing and electrofusion jointing.
No special precautions are necessary for areas exposed to the
influence of mining and earthquakes other than those precautions
mentioned in this part of ISO 16486.
It is the responsibility of users of this part of ISO 16486 to
take existing and new national regulations into account.
