Foreword
In 2021, the Bureau of Agriculture and Fisheries Standards (BAFS)-Department of
Agriculture (DA) developed the PNS SPIS - Specifications (PNS/BAFS 324:2021) and
Methods of Test (PNS/BAFS 325:2021) pursuant to a Memorandum signed by the
Department of Agriculture Secretary dated 30 July 2018, entitled “Preparation of
Philippine Agricultural Engineering Standards for SPIS”. In 2022, during the 8
th
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 subclause 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) Discharge requirement provision is transferred from the Methods of Test to
the Performance Requirements in the Specifications; and
b) PV performance ratio consideration changed to type of PV instead of PV-
pump combination;
This Standard cancels and replaces PNS/BAFS 324:2021 which has been technically
amended. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2.
