In 2022, during the 8th Review Committee (RC) Meeting of the Bureau of Agricultural and Fisheries Engineering (BAFE)-DA, the Agricultural Machinery Testing and Evaluation Center (AMTEC)-University of the Philippines Los Baños (UPLB) raised concerns on the lack of discharge requirement specified in sub clause 4.3.6 under General test condition section of the PNS/BAFS 325:2021, which is important during the testing of the SPIS. In response, the BAFS reconvened the Technical Working Group (TWG) created under Special Order No. 817, series of 2021 (Addendum to Special Order No. 81 series of 2021 entitled, “Creation of TWG for the Development of PNS for Agriculture and Fishery Products, Machinery, and Equipment”) to amend the PNS. The TWG is composed of representatives from relevant government agencies, academe, research institution, Civil Society Organizations (CSO), and private sector. The proposed amended draft PNS underwent a series of TWG meetings and a final Stakeholder Consultation conducted via online platforms before their endorsement to the Department of Agriculture Secretary for approval. The amendment includes the following significant changes compared to the previous version of this Standard: a) During testing, the system shall be observed the whole day, instead of eight hours; and b) Discharge requirement provision is transferred from the Methods of Test to the Performance Requirements in the Specifications. This Standard cancels and replaces PNS/BAFS 325:2021 which has been technically amended. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. ii  PHILIPPINE NATIONAL STANDARD PNS/BAFS 325:2022 Solar Powered Irrigation System — Methods of Test ICS 65.060.35 Table of Contents Foreword.....................................................................................................................ii 1 Scope.................................................................................................................. 1 2 Normative References......................................................................................... 1 3 Terms and Definitions........................................................................................ 1 4 General Conditions for Test............................................................................... 1 4.1 Role of the Test Applicant.................................................................................. 1 4.2 Role of the Test Representative of the Manufacturer/Supplier/Dealer................. 1 4.3 General Test Conditions.................................................................................... 2 4.4 Role of Test Engineer.......................................................................................... 2 4.5 Suspension of Test............................................................................................. 2 5 Preliminary Testing Preparation........................................................................ 2 5.1 Preparation and Verification of the SPIS Specifications.................................. 2 5.2 Test Instruments and other Materials................................................................ 2 5.3 Running-in and Preliminary Adjustments........................................................... 3 6 Performance Test............................................................................................... 3 6.1 Operation of the SPIS........................................................................................ 3 6.2 Data Collection................................................................................................... 3 6.3 Data Recording and Observations.................................................................... 4 7 Data Analysis...................................................................................................... 4 7.1 Presentation of Results...................................................................................... 4 8 Formula............................................................................................................... 4 9 Test Report......................................................................................................... 5 Annex A...................................................................................................................... 6 Annex B...................................................................................................................... 8 Annex C..................................................................................................................... 9 Annex D................................................................................................................... 11 Bibliography............................................................................................................. 14 iii PHILIPPINE NATIONAL STANDARD PNS/BAFS 325:2022 Solar Powered Irrigation System — Methods of Test ICS 65.060.35 1 Scope This Standard specifies the method for the conduct of system test for the completely installed Solar Powered Irrigation System (SPIS).
