European foreword
This document (prEN 514:2024) has been prepared by Technical Committee CEN/TC 249 “Plastics”, the
secretariat of which is held by SIS.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 514:2018.
This document includes the following significant technical changes with respect to EN 514:2018:
— term 3.1 "failure load" has been revised;
— in 5.1 the measuring range of load for the tensile or compression testing machine has been expanded.
prEN 514:2024(E)
1 Scope
This document specifies a tensile bending method and a compression bending method for determining
the failure stress of welded corners and welded T-joints made from unplasticized poly(vinyl chloride)
(PVC-U) profiles.
It is applicable to PVC based profiles used for the fabrication of windows and doors.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
failure load
load at which the test specimen breaks corresponding with the maximum load during test
4 Principle
Welded corners and T-joints made from unplasticized poly(vinyl chloride) (PVC-U) profiles are subjected
to a tensile bending or compression bending test at specified temperature and test speed.
The failure load is recorded and the failure stress is calculated.
5 Apparatus
5.1 Tensile or compression testing machine
Tensile or compression testing machines are used with the following specifications:
a) measuring range of load: 0,2 kN to 20 kN;
b) load indication with zero point setting and peak recording;
c) measurement accuracy: ± 3 %;
d) test speed: (50 ± 5) mm/min.
5.2 Test arrangements
5.2.1 Corner weld samples for tensile bending test (see Figure 1)
