3 Terms and Definitions
For the purposes of this Document, the following terms and definitions apply.
3.1 Engine coolant
The functional liquid that is compounded with antifreeze, corrosion inhibitor and other raw
materials. It is used in the engine cooling system and has the functions of cooling, anti-corrosion,
anti-freezing and anti-scaling, etc.
NOTE. The engine coolant taken directly from the original product packaging is usually called the stock
solution, which can be either the engine coolant concentrate or the engine coolant predilute.
3.2 Light-duty engine
An engine that operates for a long time at a condition of lower than the rated (net) power.
3.3 Heavy-duty engine
An engine that operates for a long time at a condition of rated (net) power.
NOTE. Most heavy-duty engines adopt wet cylinder liner design.
3.4 Engine coolant concentrate
The engine coolant, of which the water content is not more than 5%, is used for the engine
cooling system after dilution.
3.5 Engine coolant predilute
The engine coolant, with a specific freezing point, is directly used in the engine cooling system.
4 Product Classification
4.1 Classification by the engine load
of the light-duty coolant shall comply with the provisions in Table 1.
4.2 Classification by main raw materials
Coolant is divided into four categories according to the main raw materials.
4.3 Classification by moisture content
Coolant is divided into coolant concentrate and coolant predilute according to the moisture
content.

6 inspection Rules
6.1 Classification of inspection
6.1.1 Inspection is divided into type inspection and exit-factory inspection.
6.1.2 Type inspection shall be carried out under the following circumstances.
6.1.3 Exit-factory inspection is divided into exit-factory batch inspection and exit-factory
periodic inspection. When there is no change in the main raw materials and additives, at least
two exit-factory periodic inspections shall be carried out every year.
6.2 Inspection items
6.2.1 The type inspection items are all the technical requirements stipulated in Clause 5.
6.2.2 Exit-factory batch inspection items include appearance, color, smell, freezing point,
boiling point, pH, density, reserve alkalinity, and bubble tendency.
6.3 Batching
Under the condition that the raw materials and processes remain unchanged, each production
of one kettle or continuous production of multiple kettles that are uniformly mixed is an
inspection batch.
6.4 Sampling
Sampling shall be carried out in accordance with the provisions of SH/T 0065; and the sampling
volume of each batch of products must meet the requirements for inspection and reserved
sample; or randomly select samples from packaged products for inspection and reserved
samples.
6.5 Judgment rules
When the results of exit-factory inspection and type inspection meet the provisions of Clause
5, it is determined that the batch of products is qualified.
6.6 Re-inspection rules
If the results of the exit-factory inspection and type inspection do not meet the requirements of
Clause 5, double-quantity samples shall be re-taken from the same batch of products to re-
inspect the unqualified items. If the re-inspection results still do not meet the requirements of
this Document, the batch of products shall be judged is unqualified.
