Each type of lubricant has its own product specifications. There are a series of quality indicators in the specifications. The manufacturer controls and produces according to these indicators. After passing the inspection, it can be put on the market.

There are many types of lubricants and their uses are different. There are two types of indicators. One is a common indicator. All or most of the lubricant products are required to pass these indicators, although the specific data are different. The other is due to the use. Different, each variety has its own indicators.

The first category can be divided into three categories:

(1) Physical and chemical indicators indicate the intrinsic quality of the product. The basic physical and chemical properties of the lubricating oil are also the minimum requirements. Generally, the glassware used in the laboratory is measured according to standard methods, which saves time and effort, such as viscosity, flash point, etc. Production must be measured. In recent years, there have been many automated measuring instruments with physical and chemical indicators, which not only saves manpower, but also improves the measurement speed, and also reduces the measurement error and improves the accuracy.

(2) The performance index indicates the performance of the lubricating oil in use, such as anti-oxidation, anti-foaming, extreme pressure, etc. These items also have standard methods, but the experimental equipment is more complicated and expensive, time-consuming and labor-intensive than physical and chemical The indicators have certain requirements for the quality of the operators. Some of the simple lubricant production plants are also incapable of being configured. In addition to testing the quality of Changping, it can also be used for the development of new products. It is not necessary to make every batch of products in production, but to retest when there are changes in raw materials or processes and formulations, as a guarantee project.

(3) Simulated bench test The equipment used in this experiment is a special standard test machine or a representative engine actually used. The experimental conditions simulate the typical working conditions in actual use, so the experimental results can best reflect the actual situation of the lubricating oil. The performance of the lubricant is also the most convincing. The analog bench test has standard test methods. These methods consume a lot of manpower, physics and time in the experiment. The standardization process of the method also requires a lot of manpower, material resources and time.
