It was made in collaboration with the Bureau of Agricultural and Fisheries Engineering (BAFE)-Department of Agriculture (DA) as the regulatory agency for agriculture and fisheries machinery and infrastructures. This standard covers the General Methods of Test for testing and inspection of Agricultural and Fisheries Machinery without existing Philippine National Standard (PNS), Bureau of Agriculture and Fisheries Standard (BAFS), or Philippine Agricultural and Biosystems Engineering Standard (PABES). It follows the basic principle of field and laboratory performance testing which requires the determination of different performance parameters which include but not limited to capacity, efficiency, fuel and/or power consumption, and noise level. Some of the agricultural and fisheries machinery shall be tested based on the existing Standards of similar or related machinery. The draft AS underwent a series of reviews and online circulations among AMTEC engineers and stakeholders before its finalization and endorsement to the BAFE-DA. This AS was drafted in accordance with the Bureau of Agriculture and Fisheries Standards (BAFS)-Standards Development Division (SDD) Standardization Guide No. 1: Writing the Philippine National 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 is recommended as particularly suitable without mentioning or excluding others. 1 AMTEC STANDARD 001:2021 Agricultural and Fisheries Machinery – General Methods of Test 1 Scope This standard specifies the methods of test and inspection for agricultural and fisheries machinery.

There shall be at least ten (10) trials conducted. C.2 Measurement of Average Working Width and Depth of Tillage C.2.1 A depth and width meter, as shown in Figure 1, shall be used in measuring the width and depth of tillage simultaneously. C.2.2 Measure the depth and width by placing the tip of graduated depth scale to the plowed surface (point B) and putting a pin at point A of the width scale. This procedure shall be repeated for the succeeding passes. The distance between two adjacent pins is the width of tillage, and the distance between point B and baseline for reading depth is the depth of tillage. However, a plowed surface is not always leveled depending on the feature of the implement. Therefore, the tip of the depth scale shall be placed at relatively the same point in each pass. C.2.3 Determine the mean of the measured width and depth for the average width and depth of tillage. Baseline for reading depth Graduated depth scale Graduated width scale A Depth Pins for measuring B width Width Width SIDE VIEW Figure 1 - Measurement of width and depth of tillage 17 AMTEC STANDARD 001:2021 Agricultural and Fisheries Machinery – General Methods of Test C.3 Determination of Field Capacity C.3.1 Determination of Actual Field Capacity Area covered (At) and total operating time (T) shall be recorded for each trial.

C.4.5.2 To get the amount of fuel consumed (Fv), refill method shall be used. Fill the tank to full capacity or to a certain level before the test. After the test, fill the tank with measured fuel to the same level before the test. When filling up the fuel tank, extra attention shall be paid to keep it horizontal and to ensure that empty space is not left inside. C.5 Measurement of Noise Level C.5.1 The sound emitted by the machine, with and without load, shall be measured using a sound level meter at the zone of the operator/s’ ear level. The designated zone for measurement of noise level will vary for every machine for testing. C.5.2 For each data to be taken, there shall be a minimum of five (5) observations.

On the opposite side, place another two (2) poles (C, D) in similar position so that all four (4) poles form corners of a rectangle, parallel to at least one long side of the test plot. For test plot with an area less than 750 m 2, the traveling distance should be at least 19 AMTEC STANDARD 001:2021 Agricultural and Fisheries Machinery – General Methods of Test 10 m. For test plot with an area greater than 750 m 2, the traveling distance should be at least 20 m. C.6.2 Calculate the speed from the time required for the machine to travel the distance between the assumed line connecting two (2) poles on opposite sides AC and BD.
