1 Scope
This document specifies the classifications, requirements and test methods for unplasticized poly(vinyl
chloride) (PVC-U) profiles covered with paint designed for external uses which are intended to be used
for the fabrication of windows and doors.
NOTE 1 The terms lacquer, varnish and coating are used as synonyms for paint.
NOTE 2 For editorial reasons in this document the term “window” is used for window/door.
NOTE 3 For the purpose of production control, test methods other than those specified in this document can be
used.
