Technical corrigendum 1 was published on June 1, 2009. At the WG22 in Bangkok, the WG decided to publish a minor revision of this standard because the wording of a corrigendum published in 2009 was unsatisfactory. Comments were sent to Dr. Narayan and Mr. Dicker on Dec. 16, 2010 by the convener.
The convener agreed with Mr. Dicker on his proposal.

According to the discussion in Orlando, ISO 17556 was revised and ISO/CD 17556 was prepared.
CD including results of round robin tests was circulated on March 15, 2010. WG22 agreed to submit the revised draft including appropriate comments to SC5 to advance DIS. The convener sent DIS draft to DIN together with comments on CD on Nov. 22. 2010. The manuscripts were forwarded to ISO/CS on January 28, 2011. The deadline for DIS voting will be Sept. 14, 2011. The results of voting will be discussed at WG22 in Malaysia.
Project leaders: Dr. Innocenti (It), Dr. Tosin(It)

According to the results of voting received from ISO/CS. FDIS was approved. ISO 17088 was published on March 1, 2008. Concerning correction of wording to ISO 17088, a technical corrigendum was prepared and circulated to WG22 members for comments. In response to the comments, another method was discussed at the WG22 meeting in Bangkok. According to ISO/CS, corrections should be included as a minor revision. Dr. Narayan will carry out this task. The convener sent his comments to Mr. Dicker and Dr. Narayan on Dec. 3, 2010. The convener agreed with Mr. Dicker on his proposal.

11 / DIS 10210
(40.99) / Plastics – Guidelines for the preparation of samples for biodegradation test of plastics materials / New work item proposal ballot completed on May 27, 2007. The NWIP met criteria to be accepted for the SC5 work program on June 28. 2007. The title has been modified by WG22. Revised draft was distributed to WG22 on Jan. 15, 2008. Since there were no comments from WG22 members, the revised draft was circulated as the first CD. CD ballot terminated on June 16, 2008. The ballot has been approved with 91% positive vote. The comments on CD 10210 were discussed in Orlando. WG22 members agreed to the circulation of the draft as a DIS. DIS ballot terminated on Sept. 3, 2009. The comments were from UK and ISO/CS. These comments were critical in moving this item forward.
The revised DIS draft including appropriate comments was sent to Mr. Harrison on Nov. 14, 2010. After correction of this draft by Mr. Harrison, the corrected draft will advance to FDIS. However, the text will need to be improved. The work item was scheduled to be cancelled at the beginning July, 2011 under TAB time frame rules. The new limit data for submission of the FDIS will be October 30, 2011.
