European foreword
This document (prEN 1680:2023) has been prepared by Technical Committee CEN/TC 155“Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1680:1997.
prEN 1680:2023 includes the following significant technical changes with respect to EN 1680:1997:
— the title and the scope have been extended to the transport of fluids and not only to gas;
— normative references have been updated to the use in the clauses of the text;
— Clause 4 “Principle” has been modified in coherence with the scope;
— Clause 5 “Apparatus” has been modified according to the test frame used;
— specification added in 6.2 “Preparation of test assemblies” for the considered test assembly;
— in Clause 7 “Procedure” has been added Table 1 - “Test procedure” with the list of the
corresponding steps to be done;
— added 7.2 ”Application of bending force”.

1 Scope
This document specifies a test method for PE valves to maintain tightness during and after being
subjected to a force, applied as a bending moment to the operating mechanism.
Valves according to these standards are intended for use in polyethylene (PE) piping systems for the
transport of fluids.
