Philippine National Standard by the Bureau of Product Standards upon the recommendation of the Agricultural Machinery Testing and Evaluation Center (AMTEC) and the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development of the Department of Science and Technology (PCARRD-DOST). 2 PHIL][PPINE AGRICULTURAL ENGINEERING STANDARD PAES 257:2011 Agricultural Machinery - Corn Picker - Methods of Test :Foreword The formulation of this national standard was initiated by the Agricultural Machinery Testing and Evaluation Center (AMTEC) through the project "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 PAES 010-2 - 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 among several possibilities one 1S recolmmended as particularly suitable without mentioning or excluding others. In the preparation of this standard, the following documents/publications were considered: PAES 213:2004 Agricultural Machinery - Rice Reaper - Methods of Test 3 ----------------------------------------------------------------- PHILIPPINE AGRICULTURAL ENGINEERING STANDARD PAES 257::2011 CONTENTS Pages 1 Scope 5 2 References 5 3 Definitions 5 4 General Conditions for Test and Inspection 7 4.1 Selection of coconut coir decorticator to be tested 7 4.2 Role of manufacturer/distributor 7 4.3 Role of the operator 7 4.4 Test site condition 7 4.5 Test instruments 7 4.6 Test materials 7 4.7 Termination of Test 8 5 Test and Inspection 8 5.1 Verification of the technical data and information of the manufacturer 8 5.2 Performance test 8 6 Laboratory Analysis 10 7 Formula 12 8 Test Report 12 ANNEXES A Suggested List of Test Instruments and Materials 13 B Specifications of Coconut Coir Decorticator 14 C Performance Test Data Sheet 16 D Laboratory Analysis of the Samples 18 E Formula 20 4 PHILIPPINE AGRICULTURAL ENGINEERING STANDAR PAES 257:2011 ~gricultural Machinery - Corn Picker - Methods of Test 1 Scope This standard specifies the methods of test and inspection for the single-row side nlounted corn picker. Specifically, it shall be used to: 1.1 verify the mechanism, dimensions, materials, accessories of the corn picker and the list of specifications submitted by the manufacturer; 1.2 determine the performance of the machine; 1.3 evaluate the ease of handling and safety features; and 1.4 report the results of the tests. 2 References The following normative documents contain provisions, which through reference in this t1ext constitute provisions of this National Standard: PAES 103:2000 Agricultural Machinery - Methods of Sampling PAES 203:2000 Moisture Content Determination for Rice and Corn PAES 256:2010 Agricultural Machinery - Com Picker - Specifications 3 Definitions For the purpose of this standard, the definitions given in PAES 256 and the following shall apply: 3 .. 1 actual field capacity actual rate of being able to harvest corn in a given area per unit of time NOTE: Total operating time which includes the time spent for turning at the headland, adjustment, repair and troubleshooting of the machine 3.2 corn (Zea mays) ct~real grass belonging to the Poaceae family 5 PAES 257:2011 3.3 corn ear fruit of the corn plant with husk 3.4 single-row side-mounted corn picker machine attached to the side of tractor designed for picking corn 3.5 conveyance efficiency measures the ability of the corn picker to deliver the harvested corn ear to the collecting bin 3.6 field efficiency ratio of the actual field capacity and theoretical field capacity, expressed in percent 3.7 picking efficiency measures the ability of the corn picker to harvest the com ear from the corn stalk through snapping and stripping action 3.8 potential yield maximum yield per unit area 3.9 theoretical field capacity computed rate of harvested corn in a given area per unit time 3.10 overall height distance between the horizontal supporting plane surface and the horizontal plane touching the uppermost part of the corn picker NOTE: All parts of the com picker projecting upwards are contained between these two planes. 3.11 overall length distance between the vertical planes at the right angles to the median plane of the corn picker and touching its front and rear extremities NOTE: All parts of the com picker, in particular, components projecting at the front and at the rear are contained between these two planes. Where an adjustment of components is possible, it shall be set at minimum length. 6 PAES 257:2011 3.12 overall 'width distance between the vertical planes parallel to the median plane of the machine, each plane touching the outermost point of the corn picker on its respective side NOTE: All parts of the com picker projecting upwards are contained between these two planes. 3.13 running~-in period preliminary operation of the machine to make various adjustments prior to the conduct of the test until the operation is stable 4 GE~neral Conditions for Test and Inspection 4.1 Selection of corn picker Corn picker selected for test shall be sampled in accordance with P AES 103. 4.2 H.ole of manufacturer/distributor The manufacturer/distributor shall submit specifications and other relevant information about the corn picker and shall abide with the terms and conditions set forth by an official testing agency. 4.3 llole of the operator An officially designated operator shall be skilled and shall demonstrate, operate, adjust, and repair as the case maybe, related to the operation of the corn picker. 4.4 Test site conditions The corn picker shall be tested for normal operation. The site should have ample provisions for Dl1aterial handling, workspace suitable for normal working condition. 4.5 Test instruments The instruments to be used shall be calibrated and checked by the testing agency prior to the measurements. The suggested list of minimum test instruments and materials needed to carry out the corn picker test is shown in Annex A. 4.6 Test materials Corn plants shall be commonly and locally available. The maturity period of the corn plants shall be between 115 days to 120 days. The range of moisture content of corn kernel shall be 25% to 32%. 7 PAES 257:2011 4.7 Termination of Test If there is major component breakdown during testing, the test engineer from the official testing agency shall terminate the test. 5 Test and Inspection 5.1 Verification of the technical data and information of the manufacturer 5.1.1 This inspection is carried out to verify the mechanism, dimensions, materials and accessories of the corn picker in comparison with the list of technical data and information of the manufacturer. 5.1.2 A plane level surface shall be used as reference plane for verification of the dimensional specifications of the corn picker. 5.1.3 The items to be inspected and verified shall be recorded in Annex B. 5.2 Field Performance test 5.2.1 This is carried out to test the field performance of corn picker. 5.2.2 Initial data on the corn field such as width, length and number of corn plants per square meter shall be recorded. 5.2.3 Test conditions Picking operation shall be done in fields of not less than 1500 m2 (500 m2 per test trial). The plot shall be rectangular in shape with sides in the ratio of 2: 1 as much as possible. 5.2.4 Field operation 5.2.4.1 The corn picker shall be tested using field operational pattern as shown in Figure 1. 8
