This document (prEN 17665:2021) has been prepared by Technical Committee CEN/TC 261

This document has been prepared under a mandate given to CEN by the European Commission and the

The Directive (EU) 2019/904 “on the reduction of the impact of certain plastic products on the

environment” introduces the requirement that plastic caps and lids of single use plastic beverage

containers up to 3 l capacity shall remain attached to the container during the intended use stage.

This document was developed with the principal objective of characterizing the attachment of the cap

or lid to the container by a minimum separation force and the cap/lid’s ability to remain attached to the

container over the product’s intended use stage and describing the test methods along with the

performance criteria to enable demonstration that the legal requirement has been met.

The product’s intended use stage implies that the attachment feature has to resist normal handling of

the cap or lid by the consumer to access the contents and, if necessary, reclose the container for

subsequent further servings of the beverage. Intentional separation of the cap from the container will

always be possible and is formally excluded from “intended use” as considered in this document.

This document was developed taking into account the necessity not to undermine the requirements of

the Packaging and Packaging Waste Directive (94/62/EC) and its amendments in particular terms of:

— Prevention, limiting the packaging volume and weight to the minimum adequate amount to

In the course of the development of this document it was identified that the attachment of caps and lids

to the container may interfere with established and efficient plastic bottle recycling equipment,

particularly if attached caps or lids hang loose. This aspect is outside of the scope of this document, but

it is recommended that the user takes into consideration best practice guidelines established by the

This document specifies the requirements and test methods to demonstrate that plastic caps and lids of

single-use beverage containers with a capacity of up to three litres remain attached to the containers

during the product’s intended use stage. This document also addresses the need to ensure the

necessary strength, reliability and safety of beverage container closures, including those for carbonated

This document applies to the strength, reliability and safety impacted by the attachment feature and

An assessment of the attachment feature shall be carried out to ensure adequate product safety

The test shall verify that the cap or lid is able to withstand a given linear tensile force without being

The tensile testing device shall be capable of applying forces with an accuracy of ± 1 % of the measured

value. The tensile testing device shall be equipped with a clamp, forceps, hook or other suitable gripping

system capable of holding the component firmly without deformation when no force is applied.

10 separate samples shall be used for each subtest (subtest 1 and subtest 2), i.e. 20 samples.

The tests shall be performed on separate caps or lids, not repeated on the same item.

The cap or lid under test shall be applied to the neck finish for which it is designed and in accordance

The temperature of the samples to be tested shall be stabilized for 24 h at (23 ± 2) °C.
