European foreword
This document (EN 16732:2025) has been prepared by Technical Committee CEN/TC 248 “Textiles and
textile products”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2025, and conflicting national standards shall
be withdrawn at the latest by October 2025.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 16732:2015.

— Performance codes B and C related to Annex C have been updated in Table 1;
— Table 2 title has been updated;
— 5.2.2 has been added;
— Test report (7) has been increased;
— Annex M has been updated;
— New Annex N has been added.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
The different types of slide fasteners are defined by the material of the elements (teeth), which form their
slide fastener chains. They can be of metallic, moulded plastic or monofilament plastic construction.
Metallic elements can be produced from flat or profiled wire and are usually clamped around the edge of
a beaded tape. An alternative approach is to cast metallic elements directly onto such a tape. Similarly,
plastic elements can be moulded onto a beaded tape. Such cast or moulded elements might have
projections on which the slider operates to reduce abrasion of the tape.
Plastic coil slide fasteners have polyamide or polyester monofilaments that are wound into coils to form
engaging elements. The coils can be attached to the face of flat tapes by sewing. Alternatively, the coils
can be woven or knitted into the tapes as they are constructed. Monofilament plastic elements can also
be of the meander type, which straddle the tape edge.
Typical slide fastener chain types are shown in Figure 3.
1 Scope
This document specifies performance levels and test methods for the following characteristics of slide
fasteners made from interlocking components mounted on tapes: strengths of puller attachment, closed-
end slide fastener bottom stop, top stop, open-end slide fastener box, reciprocating mechanism, closed
slide fastener when extended laterally, open-end attachment when extended laterally, slider locking
device, and open-end slide fastener single stringer slider retention and slider resistance to torque.
NOTE The tests specified in Annexes B to K have been specifically devised to permit their direct application to
finished slide fasteners with a view to giving the user reasonable assurance that a slide fastener conforming to the
requirements of this document can satisfactorily fulfil its intended purpose. Annex L gives information about
sampling procedures for bulk quantities of slide fasteners.
In addition, performance levels are also specified for colour fastness to washing, dry cleaning and water,
and for dimensional stability to washing and dry cleaning.
This document is applicable to all different types of slide fasteners for general use and is not applicable
to slide fasteners for specialist purposes (for example: pressure sealed slide fasteners for diving suits).
