Type inspection items include all inspection items specified in the technical
requirements of Chapter 5.Type inspection shall be conducted in the following
circumstances.
a) When a new product is put into production or when a product is type finalized and
identified;
b) When there are significant changes in raw materials, production processes, etc.
that may affect product quality;
c) When the exit-factory inspection results differ significantly from the previous type
inspection results.
When base oils are changed, relevant tests shall be conducted in accordance with API
1509 "API base oil interchangeability guidelines for passenger car and diesel engine
oils", meanwhile the test results shall be retained for reference. When viscosity grades
are extended, relevant tests shall be conducted in accordance with API 1509 "API
guidelines for engine testing of SAE viscosity grades", meanwhile the test results shall
be retained for reference.
6.2 Group batching
Assuming the raw materials and production processes remain unchanged, each can or
kettle produced shall constitute a batch.
6.3 Sampling
Sampling shall be conducted in accordance with GB/T 4756.The sampling volume
shall meet the requirements for exit-factory inspection or type inspection and retained
samples.
6.4 Judgment rules
If both the exit-factory inspection and type inspection results meet the technical
requirements of Chapter 5, the product shall be deemed qualified.
6.5 Reinspection rules
If any of the exit-factory inspection and type inspection results fail to meet the technical
requirements of Chapter 5, double samples shall be taken from the same batch of
products in accordance with GB/T 4756, to carry out reinspection for the unqualified
items. If the reinspection results still fail to meet the technical requirements of Chapter
5, the batch of products shall be deemed unqualified.
