Mrs.Fan Dongwen,Mr.Xu Kesheng and Mrs.Li Yingzhen from Harbin Research Institute of Forestry Machinery, together with two other experts from two companies, attended the Forestry machinery international standardization meeting of ISO/TC 23/SC 13（Powered lawn and garden equipment）& ISO/TC 23/SC 17（Manually portable forest machinery）held in the United Kingdom from September 12 to 16.
The two technical subcommittee meetings were held together successively this year. China is the P-member of this two subcommittees, and Chinese delegation attended all the WG working meetings as well as the plenary meetings.
From September 12 to 13 ,ISO/TC 23/SC 13 meeting was held and the meeting had 31 experts and representatives from US, UK, China, Japan, Belgium , Germany , Italy , the Netherlands , Sweden , Poland , Austria , Canada. During the meeting, three working groups WG4,WG2,WG13 discussed technical contents of the standards on hedge trimmers ,snow throwers and lawnmowers Respectively. Suggestions and amendments on pedestrian-controlled powered lawnmowers given before the meeting by Chinese delegate were totally accepted during the discussion.
On September 15th,Chinese delegation together with all other delegates visited "APF 2016" International forestry machinery exhibition.
From September 14 to 16,ISO/TC 23/SC 17 meeting was held and the meeting had 24 experts and representatives from China, Sweden , United Kingdom , Japan , Germany , the United States , Italy , Brazil and Australia. During the meeting, four working groups WG1,WG4,WG5,WG6 discussed technical contents of the standards on Portable chain saws, vocabularies of portable brush cutters and grass-trimmers, chain movement, symbols of portable forestry machinery as well as exhaust system-caused fire risk . Most of 22 comments on vocabularies of Portable chain saws, portable brush cutters and grass-trimmers, safety of chain-saws for forest service given before the meeting by Chinese delegation were accepted during the discussion. Mr. Li Yingzhen applied for participating in the drafting group working on ISO 22868" Forestry and gardening machinery — Noise test code for portable hand-held machines with internal combustion engine — Engineering method (Grade 2 accuracy)".
There are three characteristics and achievements（The three " first time"） on these two technical subcommittee meeting in which Chinese delegation had attended ,
——For the first time, Chinese delegation have put forward so many comments (22 comments, technical or editorial);
——For the first time, Chinese experts has applied for participating in the drafting group to work on two standards developments;
——For the first time ,China participated in the Round Robin (RR) test.
The three "first time" marks that forest machinery standardization of China has substantially participated in the international standardization work, it also indicates that the garden machinery and portable forestry machinery standardization work of China has made great strides forwards.
With the improvement of China's international discourse right , we have reasons to believe that the garden machinery and portable forestry machinery standardization work of China would make greater progress and development.
