The Asian and Pacific Network for Testing of Agricultural Machinery (ANTAM) Standard Code for Testing of Power Tillers was prepared under the supervision of the Centre for Sustainable Agricultural Mechanization of the United Nations Economic and Social Commission for Asia and the Pacific (CSAM-ESCAP). The current version of the Code is based on the first edition published in August 2015, initially drafted by Dr. Chan Chee Wan and modified based on technical negotiations conducted with designated national counterparts in 2015, 2016 and 2017.
