PHILIPPINE AGRICULTURAL ENGINEERING STANDARD PAES 148:2010 Agricultural Machinery - Field Cultivator - Methods of Test Foreword The formulation of this national standard was initiated by the Agricultural Machinery Testing and Evaluation Center (AMTEC) under the project entitled "Development of Standards for Agricultural Production and Postharvest Machinery" funded by the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development - Department of Science and Technology (PCARRD-DOST). This standard has been technically prepared in accordance with BPS Directives Part 3 :2003 - Rules for the Structure and Drafting of International Standards. The word "shall" is used to indicate mandatory requirements to conform to the standard. The word "should" is used to indicate that alnong several possibilities one IS recOlmnended as particUlarly suitable without Inentioning or excluding others.
