| Resumen: | This document gives guidance and requirements for the assessment of conformity of compounds, products, joints and assemblies in accordance with the applicable part(s) of the ISO 16486 series which are intended to be included in the manufacturer's quality plan as part of the quality management system and for the establishment of certification procedures. In conjunction with the other parts of the ISO 16486 series, this document is applicable to unplasticized polyamide (PA-U) piping systems intended to be buried and used for the supply of gaseous fuels. It is applicable to PA-U pipes, fittings and valves, as well as to their joints and to joints with components of other materials intended to be used under the following conditions: a) a maximum operating pressure (MOP) up to and including 18 bar (the MOP is limited to 16 bar for CEN member countries, where ISO 16486-6 is replaced by CEN/TS 12007-6); b) an operating temperature of 20 °C as the reference temperature. For mechanical fittings conforming to ISO 17885, guidance for assessment of conformity is not given in this document. When requested, a quality plan based on the tests mentioned can be set up in agreement between user and manufacturer. The ISO 16486 series covers a range of maximum operating pressures and gives requirements concerning colours. |
