This European Standard shall be
19、given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 1995, and conflicting national standards shall be withdrawn at the latest by November 1995.

21、6, Uncontrolled Copy, (c) BSI Page 3 EN 479:1995 BSI 05-1999 1 Scope This European Standard specifies a method for the determination of the heat reversion of unplasticized polyvinylchloride (PVC-U) profiles for the fabrication of windows and doors by a test at 100 8C in an oven. 2 Principle A test p
22、iece of a specified length of profile is maintained in an oven at 100 8C for 1 h. A marked length of this test piece is measured under identical conditions, before and after heating in the oven. The heat reversion is calculated as the percentage change of the final length relative to the initial len
23、gth per pair of marks. For main profiles the differential heat reversion is calculated as the difference between the heat reversion of opposite sight surfaces of each test piece. 3 Definitions For the purpose of this European Standard the following definitions apply. 3.1 main profile profile, which
