10、dies). 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 an

11、d 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,

12、 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 cas

13、ting 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 29061-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee S

14、C 12, Passive safety crash protection systems. ISO 29061 consists of the following parts, under the general title Road vehicles Methods and criteria for usability evaluation of child restraint systems and their interface with vehicle anchorage systems: Part 1: Vehicles and child restraint systems eq

15、uipped with ISOFIX anchorages and attachments Part 2: Manual to assist the usability assessments of ISO 29061-1 (Technical Report) ISO 29061-1:2010(E) ISO 2010 All rights reserved vIntroduction The usability of a child restraint system (CRS) in terms of ease of installation of child restraint system

16、s in various vehicles, and day-to-day use with a child (securing, harnessing, adaption for a growing child, etc.), is of utmost importance to ensure that a CRS is used properly in accordance with the manufacturers intentions, and to ensure that it will provide maximum protection in a crash situation

17、 An international agreement on usability criteria and measurements is beneficial for both consumers and manufacturers. The aim of this part of ISO 29061 is to develop and validate a usability rating system for ISOFIX systems to promote improved ISOFIX design for easy and correct use. It provides ch

18、ild restraint and vehicle manufacturers with a tool for the assessment of the usability of new and current ISOFIX systems. At the same time, it provides consumers (parents and caregivers) with information on the key features related to the proper use of the ISOFIX system, and assists them in selecti

19、ng CRS and vehicles with ISOFIX systems that are easy to use properly. The rating system consists of an assessment form and a manual (see ISO/TR 29061-2). In the manual, the content of the assessment form is clarified and guidelines and interpretations are provided. The rating form is also available

20、 in Excel (xls) format for download from the ISO standards maintenance site. The usability of ISOFIX is addressed both in terms of the CRS (attachment system) and in terms of the vehicle (anchorage system) as well as the interaction of the two, emerging when child restraint systems are mounted in ca

21、rs. The usability evaluation system in ISO 29061 has been developed with participation from, and based on the experiences from, usability rating systems from Canada (Transport Canada and ICBC), the USA (NHTSA), and the EU (NPACS and consumer rating programmes, such as ICRT, ADAC). It is envisaged th

22、at this methodology could be useful for current vehicle rating systems such as US NCAP and Euro NCAP.

23、rage systems Part 1: Vehicles and child restraint systems equipped with ISOFIX anchorages and attachments 1 Scope This part of ISO 29061 provides criteria for the judgement of usability of child restraint systems (CRS) with ISOFIX attachments and their corresponding anchorages in the vehicle. This p

24、art of ISO 29061 provides criteria for a separate evaluation of the child restraint ISOFIX attachments, of the ISOFIX anchorage installation in the vehicle, and an evaluation of the interface issues when installing a child restraint system in a certain vehicle. This part of ISO 29061 covers both rig

25、id and flexible attachment systems of the CRS. NOTE Although ISOFIX is defined in the original “ISOFIX” standard (ISO 13216-1) to be a rigid system, the term “ISOFIX” in this part of ISO 29061 is extended to include flexible CRS attachments (LATCH, UAS). 2 Normative references The following referenc
