<p>This document specifies the mating dimensions for thermoplastic flange adapters and corresponding loose backing flanges intended to be used in thermoplastic piping systems for the conveyance of fluids under pressure.</p>
<p>It applies to flange adapters and loose backing flanges for use with pipes with nominal outside diameters (<i>d</i><sub>n</sub>) from 16 mm to 2 500 mm and nominal pressures up to 25 bar[1] (PN 25).</p>
<p>This document specifies the dimensions of the flange adapters intended to be used for:</p>
<p>— butt fusion piping systems;</p>
<p>— socket fusion piping systems;</p>
<p>— adhesive jointed piping systems.</p>
<p>NOTE 1 For specific connections with dimensions (e.g. <i>d</i><sub>n</sub>450 or <i>d</i><sub>n</sub>630) not covered in this document, or specific equipment (butterfly valves), specific solutions are available on the market.</p>
<p>This document is applicable to loose backing flanges made from metal, thermoplastics, or a combination of metal and thermoplastics.</p>
<p>This document also provides information on gaskets and gives general recommendations on correct assembling practices.</p>
<p>NOTE 2 Industrial applications are not covered by this document. Products intended for industrial application are covered by ISO 15493<sup>[1]</sup>, ISO 15494 or ISO 10931<sup>[2]</sup>.</p>
<p>[1] 1 bar = 0,1 MPa = 10<sup>5</sup> N/m<sup>2</sup>.</p>
