5 Inspection rules
5.1 Delivery inspection
Delivery batch inspection items: ash, softening point, toluene insoluble matter, moisture.
Delivery cycle inspection items: penetration, mass change, flash point, quinoline insoluble matter, density. In the case of stable production, the inspection cycle is one year.
5.2 Type inspection
All inspection items that are specified in Table 1 are type inspection items. Carry out type inspection in the following cases:
a) Trial type appraisal of new products or products that are transferred to the factory for production;
b) After formal production, if there are major changes in structure, materials and processes, which may affect product performance;
c) When production resumes after a long-term shutdown;
d) Type inspection according to cycle during normal production;
e) When the national quality supervision institutions propose a requirement to carry out type inspection;
f) When the user proposes a requirement to carry out type inspection.
