Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be

17、 held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark

DD CEN/TS 15945:2011CEN/TS 15945:2011 (E) 4 Introduction Ease of

19、 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

20、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 per

21、spective 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 mechanica

22、l 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 a

23、nd 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 Guid

24、e 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: functio

25、nality 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 maj

26、ority 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 requir

27、ements 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 purch

28、aser 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 spe

29、cification, 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. DD CEN/TS 15945:2011CEN/TS 159

30、45:2011 (E) 5 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 o

31、f 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

32、 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 Specificat

33、ion 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 indi

34、spensable 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. ISO 21067:2007, Packaging Vocabulary 3 Terms and definitions For the purposes of this docume

35、nt, the terms and definitions given in ISO 21067:2007 and the following apply. 3.1 consumer packaging packaging constituting, with its content, a sales unit for the final user or consumer at the point of retail ISO 21067:2007 3.2 ease of opening openability of a consumer packaging when used by the i

36、ntended users to achieve the main goal(s) supported by the packaging NOTE Ease of opening is tested as effectiveness of opening, efficiency of opening and satisfaction with opening. 3.3 effectiveness of opening accuracy and completeness with which users achieve specified goals; percentage of users w

37、ho achieve the main goal(s) DD CEN/TS 15945:2011CEN/TS 15945:2011 (E) 6 3.4 efficiency of opening resources expended in relation to the accuracy and completeness with which users achieve goal; time taken to achieve the main goal(s) 3.5 satisfaction of opening freedom of discomfort, and positive atti

38、tudes towards the ease of opening of the packaging 3.6 goal intended outcome 3.7 panel testing panel test is user based performance related measurements 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 th

39、ey 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 t

40、rained 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

41、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 operati

42、on); 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

43、 if a packaging meets following requirements: a) the packaging under study shall be easy to open; b) it shall be easy to take the intended quantity or portion from the packaging1); 1) It is crucial to the consumers satisfaction with the packaging opening system to be able to reach the content of a p

44、ackaging 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. DD CEN/TS 15945:2011CEN/TS 15945:2011 (E) 7 c) a reclosable packaging shall be easy to close. Not all questions apply to al

45、l 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 favoura

46、ble. 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 si

47、x 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. Figure 1 Examples of methods that can be used gain informa

48、tion of the openability of packaging Mechanical test methods can provide quantitative data with regards to certain attributes, such as removal torque, peel strength and ring-pull force. These data can inform on the performance of a packaging. Panel tests enable the qualitative assessment of packagin

49、g designs and allow the development of an understanding of users approach to packaging openability and handling. Panel tests can be used in conjunction with other qualitative research methods such as questionnaires and structured or unstructured DD CEN/TS 15945:2011CEN/TS 15945:2011 (E) 8 interviews. Panel tests can aid in the development process and the resulting data can inform on the performance of a packaging against predetermined criteria.
