Summary: This standard specifies the structural integrity test method for the determination of anti-engine vibration of full-flow oil filter. This test method is applicable to a spin-on filter with a maximum flow rate of not more than 100 L/min and a removable filter using a disposable filter element. This standard applies to the service period, the manufacture of product materials, mechanical properties do not change with the temperature changes in the test pieces. For other types of filters, this test method may also be used when the filter manufacturer agrees with the purchaser that it is applicable.

Foreword
GB/T 8243 Methods of test for full-flow lubricating oil filters for internal
combustion engines consists of the following parts.
- Part 1. Differential pressure/flow characteristics;
- Part 2. Element by-pass valve characteristics;
- Part 3. Resistance to high differential pressure and to elevated
temperature;
- Part 4. Initial particle retention efficiency, life and cumulative efficiency
(gravimetric meth);
- Part 5. Cold start simulation and hydraulic pulse durability test;
- Part 6. Static burst pressure test;
- Part 7. Vibration fatigue test;
- Part 9. Inlet and outlet anti-drain valve tests;
- Part 11. Self-cleaning filters;
- Part 12. Filtration efficiency using particle counting and contaminant
retention capacity;
- Part 13. Static burst pressure test for composite filter housings;
- Part 15. Vibration fatigue test with composite materials.
This Part is Part 7 of GB/T 8243.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 8243.7-2006 Methods of test for full-flow lubricating oil
filters for internal combustion engines - Part 7. Vibration fatigue test. Compared
with GB/T 8243.7-2006, the main changes in this Part are as follows.
- modified the range requirements for oil pressure gauges and
accelerometers (see Clause 5 of this Edition, Clause 5 of Edition 2006);
- modified the provisions on test pressure value and input acceleration
peak (see Clause 7 of this Edition, Clause 7 of Edition 2006);
- modified the provisions that the same test filter is used for the secondary
test direction (see 7.9 of this Edition, 7.11 of Edition 2006).
Methods of test for full-flow lubricating
oil filters for internal combustion engines -
Part 7. Vibration fatigue test
1 Scope
This Part of GB/T 8243 specifies a method of testing the constructional integrity
of full-flow lubricating oil filters to withstand engine vibrations. This test is
intended for application to spin-on type filters and detachable filters with
disposable elements with a maximum flow rate of 100 L/min.
This test method is intended for test parts made from materials that do not
experience mechanical property changes within the temperature range
experienced in service. The test may be applied to other filters if thought
applicable by agreement between the filter manufacturer and the purchaser.

The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.

combustion engines - Part 1. Differential pressure/flow characteristics
3 Terms and definitions
3.1 Definitions
For the purposes of this document, the terms and definitions given in ISO 4548-
1 apply.
3.2 Graphical symbols
The graphical symbols used in this part of IS0 4548 are in accordance with ISO
1219 [1].
6 Test liquid
The test liquid shall be oil with a kinematic viscosity of less than 10 mm2/s ± 5
mm2/s at ambient temperature [ISO viscosity class ISO VG22 at 63°C or SAE
5W at 68°C (see [2] and [3])].
7 Vibration fatigue test
7.1 Install the filter on the filter head or adaptor, applying the recommended
torque or angle of rotation for the filter to be tested.
7.2 Mount the filter and head assembly on a rigid bracket or adaptor plate with
high deformation resistance, using suitable jointing or sealant to ensure leak-
proof mating surfaces.
7.3 Rigidly mount the bracket or adaptor plate/filter assembly on the vibrator
table, ensuring that the filter polar axis is at right angles to the axis of excitation
(see Figure 1).
7.4 Connect the filter to a pressure gauge and to a source of oil pressure at
normal ambient temperature, using flexible tubing in such a way as to ensure
that it does not interfere with the vibration of the filter unit.
7.5 Attach the input accelerometer to the filter head/adaptor and the output
accelerometer to the filter, positioned approximately 100 mm from the top face
of the sealing ring, or at a distance equivalent to 0.85 of the filter length if the
filter is shorter than 120 mm. The polar axis of both accelerometers shall be
parallel to the axis of excitation (see Figure 1). Make the appropriate electrical
connections between the accelerometer, vibration control and monitoring
equipment.
7.6 Ensure that the test filter is filled with the test liquid and that all entrapped
air has been expelled from the assembly. Pressurize the assembly to the rated
pressure of the filter, or as agreed upon by the manufacturer and customer. If
no test pressure is given, then pressurize the te......
