Mutual Recognition Arrangements and Agreements (MRAs) are a hallmark of that work. Several such agreements, based on harmonized conformity assessment regimes, have facilitated much of the enormous trade between the U.S. and Asia. It is one of the reasons we’re spending a few hours in the large international airport outside of Tokyo. Some 10 years after the implementation of the APEC Mutual Recognition Arrangement (MRA), trade between the 21 economies is around $9.4T (that's Trillion with a capital Electronics Test Centre The Electronics Test Centre brings compliance, certification services, customized test and engineering to the Automotive, Medical, Military, and Commercial industries.

That is a lot of noodles. The APEC Mutual Recognition Arrangement for conformity assessment of telecommunications equipment, the world’s first multi-lateral MRA, celebrated its 10th anniversary in July 2009. Developed by the APEC Telecommunications and Information Working Group (APEC TEL), the MRA benefits manufacturers by reducing the cost of getting a product approved and by reducing the time to market. The MRA, a voluntary agreement, has fostered the expansion of technology and the access to competitively priced products amongst partner countries by reducing barriers to trade. Just as APEC continues to pursue its goals of “stability, security and prosperity,” the APEC TEL MRA Task Force continues to meet twice a year to discuss and develop additional arrangements, work out MRA issues and create bonds of friendship that reach across the oceans [1]. That beats fighting every time. Opportunity for U.S. Organizations The reality of U.S.-Japan trade in the past 40 years—since the mass proliferation of transistor-based devices—has been quite one-sided. One of the last access-issues to fall is the certification of wireless devices by U.S. Conformity Assessment Bodies (CABs). In contrast, CBs in the European Union have enjoyed this privilege since Valentine’s day 2003. (Singapore, too, has had an operating MRA since the early 2000s.) So, for roughly the past seven years, European CBs (and implicitly European manufacturers) have had a greater access to the Japanese radio market than U.S. organizations. Of course, there are other economic realities that skew this benefit, such as the desirability of U.S. products on the Japanese market and other flavors of the U.S.-Japan cultural and business inter-relationship. But now, at least, the U.S. is catching up. Within the context of the APEC TEL MRA, Japan and the U.S. have implemented the MRA for wireless devices. The initial agreement was signed Feb. 16, 2007. Another three years passed before the technical and administrative details and criteria were hammered out. Forged after a series of correspondences, meetings, queries, clarifica- 24 interference technology emc Directory & design guide 2011
Viol e t t e testing & test equipment tions, discussions, understanding (and misunderstandings) between the U.S. National Institute of Standards and Technology (NIST) and the Japanese Ministry of Internal Affairs and Communications (MIC), the U.S.-Japan MRA is now in full-force. Effective Nov. 1, 2010, NIST has been accepting applications from CABS that meet the specific criteria laid out under the agreement (for all of the bloody details, see [2]). The agreement, like a difficult childbirth, was a bit painful and took some postpartum nursing, but it is finally standing and walking. In essence, the criteria require the CAB seeking approval to gain the necessary accreditation from a designated Accreditation Bodies, and ABs can now accept and process applications from Certification US Government (NIST) Figure 2. Regulatory food chain. Bodies accredited to meet the international requirements in ISO Guide 65. The food chain is now established and looks a little like this: Under the MRA, once a candidate CAB passes muster with its domestic “Designating Authority” or DA (NIST in the U.S.), then the DA advances the proposed CAB to the DA of the other country. There is a period of review and comment and, if the CAB is accepted, then the authority to issue certifications is granted by the process of a Joint Committee, which is composed of one or more members of each DA. To understand why the agreement and final implementation were so stretched out, it is necessary to understand a few fundamental differences between U.S. and Japan practices. Some of the more interesting bits include challenges relating to differences in: 1) Laboratory/CAB Acceptance. An informal “Accreditation system” in Japan is the most different aspect between the systems. In contrast to the U.S., which relies on established mix of private and public-sector independent accrediting bodies, the Japanese system of accepting lab results was more on a relationship basis—not surprisingly given the customary and traditional internally focused system of kyoryoku (meaning "collaboration" and obliquely referring to a system of preference that makes it difficult for outsiders to break into Japan's business circles.) 2) Regulatory structure difficulties in aligning methods and product certification schemes. 3) Test methods. Test procedures for measuring specific devices are difficult to identify and cross-reference. Items 2) and 3) are essentially linked together. The method of organizing the regulations in the U.S. under the FCC system is essentially based on a Byzantine division of general device functionality and intended use mapped against frequency allocation; the requirements are, however, all covered MRA Accreditation Bodies CABs Test Laboratories Manufacturers Japanese Government (MIC) under a single title (47) of the “Code of Federal Regulations”, the how-to manual of the United States federal government. The method of organizing the regulations in Japan is, at first, a little inscrutable and buried under a half-dozen or so ordnances and radio laws, with the technical requirements based interferencetechnology.com interference technology 25
