<p>This Technical Specification presents a code of practice dealing with polyethylene (PE) pipes and fittings for buried</p>
<p>pipeline systems outside buildings and designed to distribute gaseous fuels within the temperature range ? 20 °C to</p>
<p>+ 40 °C and gives appropriate temperature-related requirements.</p>
<p>The code of practice covers mains and service lines whose components are prepared for jointing by scraping</p>
<p>and/or machining, and gives instructions for the design, storage, handling, transportation, laying conditions and</p>
<p>fusion quality control of PE pipes and fittings up to and including 630 mm outside diameter, as well as subsequent</p>
<p>joint testing, backfilling, pipe system testing, commissioning and decommissioning.</p>
<p>The jointing methods covered by this Technical Specification are heated-tool fusion jointing (butt, socket and</p>
<p>saddle fusion), electrofusion jointing and mechanical jointing.</p>
<p>No special precautions are necessary for areas exposed to the influence of mining and earthquakes other than</p>
<p>those precautions mentioned in this code of practice.</p>
<p>Existing and new national regulations take precedence over this Technical Specification.</p>
