标准范围
This document specifies the physical and mechanical properties of fittings made from unplasticized
polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of
gaseous fuels.
It also specifies the test parameters for the test methods to which it refers.
The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by
fusion jointing and/or mechanical jointing.
In addition, it lays down dimensional characteristics and requirements for the marking of fittings.
In conjunction with the other parts of the ISO 16486 series, this document is applicable to PA-U fittings,
their joints, joints with components of PA-U and joints with mechanical fittings of other materials, and
to the following fitting types:
— fusion fittings (electrofusion fittings and butt fusion fittings), and
— transition fittings.
