Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16137 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 69, Industrial valves, in collaboration with ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 7, Valves and auxiliary equipment of plastics materials, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

INTERNATIONAL STANDARD ISO 16137:2006(E)

Industrial valves — Check valves of thermoplastics materials
1 Scope
This International Standard specifies requirements for the design, functional characteristics and manufacture
of check valves made of thermoplastics materials intended to allow the flow of liquid fluids through the valve in
one direction only and to prevent backflow, their connection to the pipe system, the body materials and their
pressure/temperature rating between − 40 °C and + 120 °C, for a lifetime of 25 years, and also specifies their
tests.
This International Standard is applicable to valves to be installed in industrial pipe systems, irrespective of the
field of application and the fluids to be conveyed.
NOTE 1 Industrial pipe systems also include systems for water supply for general purposes, drainage and sewerage.
NOTE 2 Special requirements can apply to pipe systems for water for human consumption.
This International Standard is concerned with the range of DN
DN 8, DN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200,
DN 250, DN 300, DN 350, DN 400, DN 500 and DN 600
and the range of PN and Class
PN 6, PN 10, PN 16, PN 25, and Class 150 and Class 300.
