Introduction
Ease of opening is an important factor when designing consumer packaging, as it is important that consumers
of all ages, and of both genders, should be able to access the contents of the package. Consumers may
ultimately avoid the purchase of a particular type of packaging which has proved consistently to be difficult to
open. It is recognised that there is a difference in strength on average between male and female consumers.
Knowing that strength in the hands reduces with age, a panel test method that focuses on elderly consumers,
with less than the average hand strength, can help to gain a new perspective on the ease of opening of
packaging. Packaging that is easy to open for elderly consumers will, in most cases, be easy for the average
consumer to open. It is recognised that there will be consumers with extreme impairment that this specification
cannot represent.
To present valid mechanical test methods for the wide range of packaging present on the market today is not
possible in this specification at this time. A test protocol inspired by the principles described in the ISO 20282
series of standards is therefore used in Annex A. However, it should be noted that mechanical testing and
sensory test by trained panel are useful tools when developing easy to open packaging or for quality control.
We recommend the generation of mechanical data to allow the introduction of new methods, as a means of
demonstrating compliance with this specification.
When appropriate; CEN-CENELEC Guide 6, “Guidelines for standards developers to address the needs of
older persons and persons with disabilities” and the referenced documents were considered when drafting the
specification.
This document specifies procedures for ease of opening. It should commensurate with the maintenance of:
functionality throughout the supply and user chain;
safety and hygiene for both product and user/consumer;
acceptability of the packed product to the user/consumer.
The purpose of the test methods should be to evaluate whether a particular design of packaging can be
considered easy to open by the large majority of consumers, including elderly consumers. The test methods
may be used by, for example:
a designer or manufacturer; to check whether ease of opening requirements have been met;
a potential purchaser or consumers organisation to check whether a particular design of packaging meets
their requirements regarding ease of opening;
a manufacturer, potential purchaser or consumers organisation to compare alternative products.
The results can provide evidence of the ease of opening of a particular design of packaging to potential
purchasers. A test may be carried out by the manufacturer or purchaser directly or by assigning the task to an
appropriate test organisation.
Where the information derived from the test is used for any purpose other than for internal technical or product
development, for example to make a public statement regarding packaging ease of opening in relation to this
specification, testing should be carried out, or should be independently verified, by an accredited test
organisation. The information should be provided in sufficient detail to allow replication of the data-scoring
methods by another organization if the test is repeated.

1 Scope
This Technical Specification specifies the following for all adult consumers:
criteria for ease of opening of packages;
methods for evaluating the ease of opening of consumer packages.
The purpose of this Technical Specification is to specify test methods to evaluate the ease of opening of
consumer packages, in order to improve easy access to the contents. For packages regulated for safety or
similar reasons, e.g. packaging of dangerous goods and substances, medicinal products, and medical
devices, those regulations take precedence.
This Technical Specification applies to all packaging that does not require an opening tool and to packaging
that is purchased with an integrated opening tool.
NOTE 1 The method(s) described in this Technical Specification could also be applicable to other types of packages
when measuring ease of opening.
NOTE 2 This Technical Specification can be used to test most consumer packages. There are, however certain
packaging types that cannot easily be tested with the described methods, such as e.g. very large packaging used to
protect refrigerators and washing machines.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

NOTE In a panel test, a product is tested by a group of individuals trying out a product in a relative controlled or
experimental setting, where they are given specified task(s) to perform.
3.8
mechanical testing
documented and reproducible mechanical test methods intended to measure the resistance of the relevant
features of a package/packaging system by use of appropriate equipment
3.9
sensory test by trained panel
members of the panel are trained to qualify and quantify sensory properties of the ease of opening of
consumer packaging
4 Criteria for ease of opening of packaging
Ease of opening of packaging is defined as “the openability of a consumer packaging when used by the
intended users to achieve the main goal(s) supported by the packaging”. Such main goals can where
appropriate, include opening and closing, as well as accessing the intended quantity of the product.
The users shall be able to achieve their main goals:
with a high success rate (effectiveness of operation);
within an acceptable task time (efficiency of operation);
with an acceptable level of satisfaction with operation.
Packaging will be considered to be easy to open if the large majority of adult consumers find it to be effective,
efficient and satisfactory as set out above. The test results, from e.g. the panel test in Annex A, can be used to
determine if a packaging meets following requirements:
a) the packaging under study shall be easy to open;
1)
b) it shall be easy to take the intended quantity or portion from the packaging ;
1) It is crucial to the consumer’s satisfaction with the packaging opening system to be able to reach the content of a
packaging in an easy and safe way, however, if unfilled packaging is tested, this question can be omitted. The reason for
omitting the question is recorded in the test protocol.

CEN/TS 15945:2011 (E)
c) a reclosable packaging shall be easy to close.
Not all questions apply to all packaging since the goals of the packaging will be different for different
packaging designs e.g. reclosable and non-reclosable packaging. The relevant questions will therefore
depend on the form and intended use of the packaging. The overall judgement of the packaging under study
shall be favourable.
EXAMPLE For non-reclosable packaging only questions a), and b) will apply, while all questions are relevant for
most reclosable packaging.
5 Test methods
Ease of opening can be evaluated in several different ways, by panel tests, mechanical tests, sensory panels
etc. During the three year to six year lifespan of this Technical Specification new methods will be developed
and a set of annexes produced to describe these methods. Figure 1 shows examples of different methods that
may be added as annexes to this Technical Specification.
