ISO 16871:2003 (R2024)

ISO 16871:2003 specifies a method for exposing plastics pipes and fittings, individually or assembled, or as pieces therefrom, to natural weathering in order to assess changes. The exposure is considered appropriate for evaluating components subject to yard storage prior to installation and use without further exposure to direct weathering, and is quantified to promote rationalization of exposure doses and comparability of data. For exposures appropriate to tropical or equatorial conditions, attention is drawn to ISO 877.
