Abstract
The purposes of this research were to study details of labeling and packaging of 35 brands of the
replacement brush cutter blade purchased in Surat Thani province and to study the steel grades of the selected 7 brands. The samples could be classified by manufacturer into 3 product categories: Imported Blade (IB), Local Manufacturer Blade (LMB), and Unidentified Blade (UB). The numbers of IB, LMB, and UB were 4 (11.4%), 15 (42.9%) and 16 (45.7%) brands, respectively. Out of the 14 LMB brands, 2 brands had a completed details in Thai language details on labels, 2 brands were traceable by internet searching. Other brands were not traceable. In additions, the investigations of steel grades found that the blades were steel grades of 1050 1065 1070 and 1080, by referring to ASTM A682, which they were not tool steel grade as referred by ASTM A686 and JIS G4401.
