FOREWORDp1
For the year 2000, the Agricultural Machinery Testing and Evaluation Center (AMTEC) of the College of Engineering and Agro-Industrial Technology (CEAT), University of the Philippines Los Baños (UPLB), initiated the drafting of thirty five (35) agricultural engineering standards which includes updating of existing Philippine National Standards, pursuance of pending draft standards, adoption of international and related standards from other engineering fields, and formulation of new standards.

These standards include standard terminology, standard specification/application and standard method of test for agricultural production machinery, postharvest machinery, engineering materials, and agricultural structures.


These Standards were technically drafted in accordance with PNS 01:Part 4:1998 - Rules for the Structure and the Drafting of Philippine National Standards.

Technical Committees responsible for reviewing the draft standards were composed of members from different private and government agencies/institutions.

The Technical Committee reviewed the draft standards taking into account their appropriateness to Philippine conditions. Each standard was circulated to no less than fifty (50) private and government agencies/organizations concerned to solicit comments, suggestions and reactions. The draft standards were presented to the Philippine Society of Agricultural Engineers (PSAE) and subjected to a public hearing organized by the National Agriculture and Fisheries Council (NAFC). The comments and reactions received during the presentation and public hearing were taken into consideration in the finalization of the standards.

The PSAE unanimously passed Resolution No. 25 s. 2001 adopting these standards as technical standards of the agricultural engineering profession. Likewise, these standards were adopted by the Department of Agriculture and shall serve as National Standards for Agricultural Engineering under Administrative Order No. 10, s. 2002.
These standards shall, hereon, be referred to as Philippine Agricultural Engineering Standards (PAES).
