This International Standard specifies a method for exposing plastics pipes and fittings, individually or
assembled, or as pieces therefrom, to natural weathering in order to assess changes.
NOTE 1 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.
NOTE 2 For exposures appropriate to tropical or equatorial conditions, attention is drawn to ISO 877.
Diese ÖNORM legt Verfahren fest zur Freibewitterung von einzelnen oder zusammengefügten Rohren und Formstücken aus Kunststoff oder Abschnitten davon, um Änderungen zu bewerten.
