CB/T8243.3--2003/ISO4548-3:1997 Introduction
CB/T8243.3--2003/ISO4548-3:1997 Introduction
CB/T8243.3--2003/ISO4548-3:1997 specifies the standard test procedures for measuring the performance of fully integrated filter elements for internal combustion engines. The standard is composed of individual parts. Each part involves a certain working characteristic. The whole test can provide necessary information for evaluating the filter performance. However, if the user and the previous two parts are separated, they can also be carried out separately.
In order to make the expression of this part conform to the requirements of the current ISO standards, this part has been revised. The third major change is to make a "editorial modification" to the layout and text, and also make a few changes to the technical content. In order to provide the "ISUVG and SAE grade oil grades for testing, the test bench size was adjusted to be consistent with the [SC8 test. In addition, the flow chart on the test bench was relocated to the bottom of the flow chart. 1 Scope

This part of GBT8243 uses the ratio Tongli or the number specified in IS191. 5 Test working characteristics
The filter is often subjected to high pressure difference during use, especially when it is blocked after long-term use, and it will also be affected by high working temperature. The car test system is used to determine the working capacity of the filter element under the specified pressure difference under the simulated working temperature. 6 Test filter
6. 1 Filter Types
To install and verify the filter on the test bench, the following types of filters shall be considered: a) Spin-on filters (with or without a sensor element) not included in the replacement parts: b) Replaceable parts include spin-on filters that are optional and can be replaced by customers; 5) Other filters, usually called replaceable filter elements, and usually have their own filter seats 6.2 Before testing: Unless the filter assembly is damaged: The integrity of the filter element shall be checked as specified in 152942. The test bench
Figure 1 shows The overall layout of the test bench shall be consistent with the components listed in (1) to (4): including the necessary piping, support, etc.
7.1 Oil foil
The oil tank should have sufficient flow capacity and should be equipped with a constant source controlled heater and cooler to maintain the specified test temperature. The arrangement of the heating element should avoid local overheating of the engine oil. When the engine is stopped, the return pipe to the oil tank and the H oil pipe should be bypassed to ensure that the oil tank is moist. The bottom temperature is adjusted to keep the oil temperature within the specified range. 7.2 Regulating valve
The regulating valves 3 and 10 are used to control the pressure and flow rate. They should use metered or diaphragm valves. 7.3 Flowmeter
The flow rate should be suitable for the use of a machine with a moving load of m", and the flow meter in the same source and filter pipeline should be recorded. In addition, the flow meter can be installed in the filter outlet pipeline. 7.4 Filter installation bzxZ.net
4.1 For the various types of filters specified in 6.1a>, a test seat is required. A typical example is shown in Figure 2: The oil inlet measuring hole on the filter housing is marked with the outlet oil micro-pressure terminal. 7.4.2 For the various types of filters specified in t.1h) and 6.1c, the screw holes for measuring or filtering the total pressure should be set in the test filter so that it is connected to the upstream and downstream of the filter. Regardless of where they are actually placed, these measuring holes should be set in the filter with low flow velocity and decay flow. Alternatively, a special test hole can be used to measure the difference in leakage. The typical housing is shown in Figure 1. Test fluid ||tt| |8.1 Test fluid for high pressure resistance test
Select appropriate engine oil and temperature for the test, so that the running temperature reaches 50)/. The oil temperature shall not exceed 100%
: At 3°C, use V460:SAE engine oil [suitable to reach 500mm+, 8.2 Test fluid for high pressure resistance test
Unless the filter has been agreed with the manufacturer, use approved standard oil for the test. Note: The compatibility of the core material and the engine oil will affect the performance of the filter. At the same time, it is good to use the head to ensure fast use and easy use of this characteristic, but this conclusion is only valid as a comparison filter element when using this engine oil. 9 Test condition measurement accuracy
The test condition measurement is kept within the accuracy specified in Table 2, and the measurement unit of the difference is also "Pa (kPa), Table 1 Ketone content accuracy

Death: The test should be carried out in this core! 10.1.1 Install the test instrument as shown in Figure 1. Production
10.1.2 Add the cleaning material to the test instrument and let it pass through the test pipe. In this step, the test is carried out on the wide range of the test instrument,

GB/T 8243.3—2003/ISO 4548-3, 199717, 1.3 Turn on the heater or cooler. The temperature can reach the required humidity (see 4.1), and the temperature gradually stabilizes. 10.1.4 When the oil temperature in the single pen reaches the compensation time: let the oil flow into the pad and increase the flow to make the source pressure reach 175kPa, then continue to increase the flow rate, so that the upper difference increases by 25kPa, until it reaches 50kPa or other values ​​agreed with the user. Each pressure difference should be maintained for 1minl. The program should be executed for a period of time. The required amount should not exceed the setting. If the required pressure cannot be reached by the clean test wave, a certain amount of material can be added during the test. Note: The number of times should not affect the accuracy of the core. 10.1.5 Before reaching the required pressure, if the pressure does not rise again when the flow is increased or the pressure difference decreases significantly, the test should be terminated. After the test, remove the filter element in the housing and check whether the residual oil in the filter element is damaged (see -2). If there is no obvious damage, check the integrity of the filter element according to the provisions of 1902942. 10.2 High temperature resistance test
10.2.10.2.7 Soak the filter assembly completely in the test oil (see 8.2) 10.2.3 Place the container in a drying oven with a temperature of 133°C, unless otherwise agreed with the user. After heating, keep the temperature at 9°C.
10.2.4 Take out the filter from the drying oven and keep it cool to below 40°C. 10.2.5 Remove the oil from the filter assembly without adding the filter. 10.2.6 Repeat the tests described in 10.2.2~10.3. Note: Do not heat! The same fee is charged by the user, and the soaking time of the sea chicken oil is as long as 192℃. 10.2.7 Test the filter assembly according to the sequence specified in 10.1.1~-0.1.5. 11 Test result report
