Introduction

GB/T 8243 (all parts) provides a unified test procedures for the determination of full-flow engine oil filter performance. This series of standard

The components are divided according to each part involved in a certain performance characteristics.

The entire test method provides the necessary information for assessing the characteristics of the filter, but if the user and the manufacturer agree that the entire test set

Act can also be used separately.

Full - flow engine oil filter test method

Part 5. cold start simulation and hydraulic pulse durability test

1 Scope

GB/T 8243 provisions of this part of the determination of the full-flow engine oil filter against internal pressure such as the engine at cold start

Fluctuation and in the course of work to withstand the ability of periodic changes in internal pressure test methods.

This test method is suitable for the maximum flow of not more than 100L/min spin-on filter and disposable filter disposable filter

Cleaner.

This test method is also applicable to other filters that the filter manufacturer and the buyer agree on.

Note. This test method can not replace the simulation environment test (for example, at ultra-low temperature). If the test is required, it shall be agreed between the supplier and the buyer.

4 test work characteristics

The filter is subjected to pressure fluctuations under cold start conditions. The test method specified in Chapter 8 is to verify the filter housing and seal

Ring Anti-Specified Number of Times Starting Condition High Pressure Fluctuation Ability.

In normal work process, the filter must also withstand the cyclic pressure changes, the test method specified in Chapter 9 is to verify the filter housing and the dense

Seal against the ability to cycle pressure cycles.

5 test bench

The test rig shall include the following components, as well as the necessary piping, fittings and brackets (see Figure 1).
