The formulation of the AMTEC Methods of Test (AM) was initiated by the Agricultural Machinery Testing and Evaluation Center (AMTEC)-University of the Philippines Los Baños (UPLB) in response to the need for a reference standard for different machineries without existing Philippine National Standards (PNS) and Philippine Agricultural and Biosystems Engineering Standards (PABES). The standards were made in collaboration with the Bureau of Agricultural and Fisheries Engineering (BAFE)-Department of Agriculture (DA) as the regulatory agency for agriculture and fisheries machinery and infrastructures. The draft AM underwent a series of reviews and online circulations among AMTEC engineers and stakeholder consultation before finalization and endorsement to the BAFE-DA. The AM was drafted in accordance with the Bureau of Agriculture and Fisheries Standards (BAFS)-Standards Development Division (SDD) Standardization Guide No. 1: Writing the Philippine National Standards.
