8 Proposal stage New work item proposal reparatory stage Working draft WD Committee stage Stages & Approval requirements SVAT score>15 This is only for indicative purposes simple majority of P-members. participating 5P-members 5 experts consensus, or Committee draft (CD) support from 2/3 of the P-members voting Enquiry stage Draft International Standard (DIS) Approval stage inal draft International Standard (FDIS) Publication stage nternational Standard (IS) 2/3 of P-members positive no more than 1/4 votes negative 2/3 of P-members positive no more than 1/4 votes negative

9 Standards Value Assessment Tool (SVAT) Will be used for NWI proposals & 5-years review Intended to quantify the market relevance of NWI proposals and published standards Five questions on voting form (all concerning market relevance) Member bodies award points (from 1pt to 5pts) After ballot, SC secretary calculates average number of points NWIP> 15 points = accepted 5-year review< 9 points = withdraw

10 Revised timeframe for standards (TMB decisions): The 3 years and 7-years rule for cancellation has been changed to 2 and 5 years, respectively. (effective 2003/10/01) 3 time frames (effective 2003/09/01). 36 months (recommended). 48 months (extended). 24 months (accelerated)

11 Crown PlazaMaastricht, the Netherlands Sept. 30, 2003 (Tues.) Participants 24 (15 countries). ISO 14855/DAM1(Use of mineral bed instead of mature compost) A revised DAM1 will be voted as DIS.. CD 17088(Test scheme and Specifications) Reactivated. But, due to 2 years cancellation this item was cancelled. Based on 60%(theoretical) pass level NWI should be submitted.. DIS (Disintegration, in a laboratory-scale) This document to be published.. Items for future work Japan intends to propose new work item related to composting test of a laboratory scale. Seven countries (Belgium, China, Italy, India, Japan, Sweden, USA) will carrry out ring testing on NWI.

12 ISO 14855/DAM1(Use of mineral bed instead of mature compost) The documents will be voted as DIS. ISO/CD (Test scheme and Specifications) NWI (based on 60% theoretical pass level ) should be submitted. 90% relative, theoretical Biodegradation: EN % relative Biodegradation (blends and block): ASTM D % relative Biodegradation (single polymers) : ASTM D % theoretical Biodegradation: JP(BPS) ISO 14851,14852, 14855

13 DIS (Disintegration, in a laboratory-scale) he revised document incorporating corrections is to be published. Items for future work panese proposal: omposting test by gravimetric method in a laboratory-scale CO will be absorbed by soda lime, and determined by the increased weight of absorption column. Dr. Uematsu Next meeting he next meeting will be held on Tuesday, October 19, 2004 at Chendgn in China.
