Other

Aside from the Expert Meeting, an additional meeting was organized and held by JAPIA, where the current status of introduction of the seatbelt regulation (ECE R16) was discussed with people involved in regulation and type approval activities in Asia. Attendees: Japan (JAPIA members, Mr. Narusawa of NTSEL, and Mr. Akiba of JASIC), Thailand (TISI and DLT), Malaysia (SIRIM), and Vietnam (VR) Current status of each country 1) Thailand:

It has been agreed between TISI and DLT that TIS mandatory standards be drafted and implemented for seatbelts, glazing, etc. Based on that agreement, TISI is currently drafting seatbelt performance standards that resemble the ECE R16 requirements. As for seatbelt installation requirements, DLT will adopt ECE R16 as is. However, further discussions between DLT and TISI are necessary with regard to adoption of ECE R16 in Thailand. 2) Malaysia:

ECE R16 requirements have already been introduced into MS1175-2003 (amended in 2004) with the exception of the ISO-FIX requirements. This standard and the MS1154-2004 Webbing standard are mandatory. In actuality, it is mandatory only to CKD vehicles and operated by the transport authority JPJ. It is treated as a recommended standard for CBU vehicles. 3) Vietnam:

R16 requirements have been standardized as TCVN7001-2002 Rev.3, which is an optional standard, but the ISO-FIX requirements are not included. 4) Japan:

R16 technical requirements are included in Technical Standards. Adoption of R16 in Japan is scheduled to be discussed when it is amended in future. 7. Wrap-up This Expert Meeting was unique in that it addressed the issue of ECE standards on seats and seatbelts, which are important vehicle components for protection of occupants in the compartment, and that it was the most attended Expert Meeting ever with people coming not only from Thailand but also from other Asian countries. In addition, at the question-and-answer sessions, many questions were raised enthusiastically about activities at the administration level such as interpretation of specific provisions and type approval testing procedures, reflecting the attendees’ deep interest in the issue. JASIC would like to provide continuous support in holding Expert Meetings in the future for even more active discussions at the meetings. On the other hand, problems that Contracting Parties to the 1958 Agreement are facing have also been pointed out; for example, more adjustment between the standardization authority and the type approval authority is necessary. JASIC became strongly aware of the need to continue to provide in-depth support towards establishing automobile type approval system not only in Thailand but also throughout ASEAN countries.

Key Note Speech at the 6th Asia Expert Meeting

Good Morning! Mr. Chalermtai YANPIRAT, Director, Engineering and Safety Bureau, Department of Land Transport, and everyone participating in this meeting. My name is Tadaomi AKIBA, Executive Director of Japan Automobile Standards Internationalization Center, JASIC. On behalf of JASIC, I would like to extend our heartfelt appreciation to all the people

who are kindly taking part in this 6th Asia Expert Meeting which Department of Land Transport in Thailand organizes on a theme for Vehicle Passive Safety items, ECER14, R16, R17 and R25. Also I am very pleased that Department of Land Transport accepted us, National

Traffic Safety and Environment Laboratory (NTSEL) and JASIC as experts from Japan. The Automobile Type Approval Test Department, one division of the NTSEL, is the only organization in Japan that performs official tests of Motor Vehicles about the conformity with safety, environmental, fuel consumption and other standards of Japan from a fair and neutral standpoint. This department is the only technical service assigned by Ministry of Land,

Infrastructure and Transport in accordance with the rule of the 1958 Agreement. Accordingly the department has a great deal of knowledge on not only domestic type approval system but also international type approval system, therefore I expect that their participation can bring active discussion among participants concerned at this Expert Meting. Our mutual understanding on concept of the Expert Meeting is that the meeting is to

be held voluntarily based on each country’s needs as well as to be steered by Asia G/I Meeting. At the G/I Meeting held in Kuala Lumpur in last November, it was evident that holding the Expert Meeting is very useful and helpful for the people examining the contents of the 1958 Agreement, ECE regulation as sole international technical regulations and Mutual Recognition Approvals among Asian region. I would like to emphasize that many countries, of course including your country, expressed their intentions at the G/I Meeting that they will hold the expert meeting in near future, and their plans were specified in Wrap Up statement. I have a high regard for an effort and enthusiasm of Department of Land Transport and people concerned in order to realize this Expert Meeting. Before this 6th Expert Meeting, two successful Expert Meetings have been held in

Thailand by Department of Land Transport. Specifically, the 1st Expert Meeting on ECE R48 (installation of lamps) and the 3rd Expert Meeting on ECE R13H (braking). This means that as many as half of the Expert Meetings have actually been held in Thailand. Again, in this fact, we can

clearly see the effort and enthusiasm of Thai government and industry, which I admire greatly. On one hand, rapid motorization has contributed to the expansion of automobile-

related industries in Asian countries over the recent years. But on the other hand, rapid motorization has also brought public issues over traffic safety and environmental protection such as the prevention of air pollution. I am sure, all the people here agree on the urgent need to enhance the automotive safety and environmental regulations in Asian countries. However, because automobiles are a type of product that is distributed on an international scale, it is not realistic to improve our automotive laws and regulations without taking the laws and regulations of other countries into consideration. I think we all see the importance of Asian cooperation not only in harmonizing our regulations within Asia but also harmonizing our regulations from the global standpoint. I would like to congratulate you that your country joined the 1958 Agreement this

year as the result of the efforts made by Department of Land Transport and other government agencies of Thailand. And, I expect that your accession to the 1958 Agreement will accelerate the movement towards establishment of the Vehicle Type Approval system in your country and contribute significantly to improving safety and environment. At an AMEICC (ASEAN economic ministers - METI Economic and Industrial

Cooperation Committee) meeting held in Vientiane, Laos about a month ago, we presented JASIC activities to promote mutual recognition of approvals under the 1958 Agreement of UN/ECE/WP29 as part of our ASEAN automobile-competition strengthening project. Our presentation was followed by discussion on Japan’s support activities that should

be undertaken in the future. Similarly, I would like all of the experts gathering here today to recognize the importance of the concept of ECE Regulations, that is, mutual recognition of approvals. This system works as an arm of companies in the automobile industry when they advance their global business operations. With these new changes in Asia, this Expert Meeting provides a timely opportunity

to consider adopting the ECE Regulations by deepening your understanding of their test procedures, technical requirements and certification issues related to Vehicle Passive Safety. JASIC would like to cooperate with you as much as we can. In addition, I do hope that the outcome of this Expert Meeting will be reported at the

Asia G/I Meeting. Next G/I Meeting will be held in Indonesia in the end of November, where Fourth series whose aim is to discuss continuously “Accession to 1958 Agreement and improved Asian presence at WP29.”

This G/I Meeting will mainly discuss how to establish Vehicle Type Approval system and incorporate the ECE Regulations into such system. I hope to see many of you there at the G/I Meeting as well. I would like to thank you again for the participation of so many government and

industry members. Your presence here gives me confidence that interest in harmonization and the mutual recognition of approvals is growing in your countries and that there is increasing awareness concerning the importance of cooperation between governments and industries. Please feel free to take part in discussions today, so that this Expert Meeting will

prove beneficial in enhancing traffic safety in your countries. Now, I will finish my opening address, hoping that the good friendship between you and JASIC will continue for a long time to come.

Thank you.

Tadaomi AKIBA Executive Director, JASIC
