NOTE 1    A basic test matrix in Annex B provides an overview of the testing scheme.
It is recommended for the manufacturer to have a management system such as ISO 9001[4] or equivalent.
NOTE 2    If certification is involved, certification bodies and inspection bodies operating according to ISO/IEC 17065 and ISO/IEC 17020 are considered to be competent.
In conjunction with the other parts of the ISO 16486 series (see Clause 2), 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[1] (the MOP is limited to 16 bar for CEN member countries, where ISO 16486-6 is replaced by CEN/TS 12007-6[1]);
b)    an operating temperature of 20 °C as the reference temperature.
NOTE 3    For operating temperatures different to 20 °C, derating coefficients can be used (see ISO 16486-6). CEN member countries use CEN/TS 12007-6[1] and ISO/TS 16486-7 (this document) as a basis, but they can also request additional requirements. For non-CEN member countries, information for dealing with special cases for PA-U can be found in ISO/TS 16486-7 (this document) and PPI TR-3.[7]
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.
