(1) The Status of Action at Toshiba and Electronic Company regarding RoHS in Japan (2) The Status of Action at National level regarding RoHS in Japan (3) Background of Standardization for JIS C and its further use Contents:

Surprise and Sensation Toshiba Group is doing its utmost to manage chemical substances so that customers can use its products with confidence and in order to prevent release of environmentally hazardous substances. Toshiba’s Policy for “Environmental Sustainability” Control of Chemical Substances

Our Management System to Reduce Environmental Impact of Products Complete Recycling of Products Thorough Monitoring of Hazardous Materials Thorough Elimination of Hazardous Materials ・ Pb - Free Solder ・ Trivalent Cr coating ・ Cd - free AC Cable, etc. Environmental Conscious Design Life Cycle Assessment ・ Monitoring of Pb, Cd, Hg, etc. during Procurement ・ Monitoring of Water and Air Quality (F, Cl, As, NOx, SOx, etc.) ・ Materials Recycling for PE and Metals ・ Styrene Foam - Free Packaging

Our Monitoring System for Hazardous Substances in Procurement Screening ： Non Destructive Analysis by X-Ray Fluorescence method Verification ： Verification Analysis by ICP- AES, GC-MS,etc NG Pass Gray Toshiba’s Monitoring System for Hazardous Substances in Green Procurement Supplier ASupplier B Material Declaration Pb: Yes / No Cd: Yes / No Hg: Yes / No Material Declaration does not guarantee the absence of hazardous materials during procurement. However, sometimes the following occur: ・ Materials Containing Hazardous Materials Mistakenly Delivered by Suppliers ・ Contamination during Production Pb: Yes / No Cd: Yes / No Hg: Yes / No Material Declaration

Example for X-ray Fluorescence Monitoring for Procurement SnAgCu Solder XRF is a useful method for rapid and sensitive screening of hazardous substances for many materials W. Araki, K. Mizoroki, M. Oki, M. Takenaka: Anal. Sci., 2005, 21, 869.

Example for ICP-MS Analysis for Procurement Activities of the industry as a whole : These methods are now being considered for an International Standard Method in IEC TC111 WG3. We are developing methodologies according to IEC. Sample (0.2 g) Microwave Digestion HNO 3 /HF 10ml Cooling Dilution ICP-MS* (Pb, Cd, Hg, Cr) *ICP-MS: Inductively Coupled Plasma Pass Spectrometry Cable Code

XRF GC-MS Br: > 300 ppm From the practical and cost-effective aspects, we should consider a simple way for finding PBB/PBDE. Next Step: PBB/PBDE analysis by XRF Ratio of PBB/PBDE to the other Flame Retardants

The developing methodology ● Nano dots/Mass Spectrometry (AIST*) ● Raman Spectrum （ Fujitsu ） ● TOF-SIMS （ Mitsubishi ） ● Pyro-GC/MS (Shimadzu) ● Ion attached Mass Spectrometry (Toshiba) etc. First Screening ： XRF(Br) Verification Test ： GC/MS NG OK Gray Second Screening ： PBDE/PBB The developing methodology for Second screening of PBB/PBDE *National Institute of Advanced Industrial Science and Technology

Sample (Simple Disassembly) The selection of High risk materials Preparation for analytical sample XRF Verification Analysis Ordinary tools Exemption If necessary, (Detailed Disassembly) OK ? Low Risk High Risk Problem of Sampling Matter ・ Sampling is one of the difficult topics in Japan ・ A performance-based sampling/analysis system is desirable Where? How?

-The Status of Action at National level regarding RoHS in Japan

IEC/TC111 IEC/TC111 Japan NC TC111 WG1 (MD) WG2 (ECD) WG3 (RoHS) TC111 Japan NC WG1 (MD) WG2 (ECD) WG3 (RoHS) Secretary ： Italy Chairman:Japan Secretary : JEITA* JEITA: Japan Electronics & Information Technology Industries Association IEC/TC111 Japan National Committee (2005/3 ）

JEITA’s Activities and Organization Activities: 1.Development of New Fields 2.Promoting International Cooperation 3.Working on Environmental Preservation and Safety Measures 4.Advanced Technical Standardization and Technological Development 5.Implementing Surveys and Analyzing Statistics 6.Reinforcing the Industry’s Operating Environment 7.Maintaining Effective Public Relations and Staging Exhibitions

Japan Green Procurement Survey Standardization Initiative 2005/5: Publishing the Joint Industry Guide (JIG) for Material Composition Declaration for Electronic products Collaborations with EICTA( European Information, Communications and Consumer Electronics Industry Technology Association) and EIA (Electronic Industries Alliance) JIG defines the methodologies in identifying target chemical substances and standard that should be followed by suppliers when responding to the survey

Survey Substances List (Level A JIG 101) : 15 Substances

Survey Substances List (Level B JIG 101) : 9 Substances

-Background of Standardization for JIS C0950 and its further use

・ Basic aspect - Effort of top runner company should be acknowledged - Material restriction like RoHS is not necessary at the present stage Pollution with the six materials (RoHS ) is not serious Procedure for exemptions is vague and complicated Lack of performance and safety evaluation on alternative material - Promote environment conscious design Chemical Substance Management System

Background ： The regulation for electric and electronic equipment. The same regulation concept as those of EU RoHS, China, and US in order to prevent the circulation of non- compliant equipment domestically. Related Law: Law for promotion of Effective Utilization of Resources The methodology for the restriction ： JIS C0950 An object of products: 7 products TV, Air conditioner, Refrigerator, Landry, PC, Microwave oven, Clothes Drier Note: Application of this Standard to other electrical and electronic equipment is not restricted. An indication Mark ： Presence Mark: Orange Mark, Non Presence Mark: Green Mark Date of Establishment ： 2006/7/1 The Marking for presence of the Specific chemical Substances for electrical and electronic equipment (J-Moss)

Introduction –Standardize marking method of the specific chemical substance in electrical and electronic equipment Promote improvement of management of the specific chemical substances in enterprise, throughout supply chain and each stage of life cycle Easy to understand for consumers Improvement the effectiveness quality, use of resources and reduction of environment load –Promote adequate management on electrical and electronic equipment J-Moss -1
