The Type inspection items shall be the ones in 4.1, 4.2, 4.3, 4.4 and 4.6. Type
inspection shall be carried out in one of the following situations:
a) Finalized appraisal for the trial production of new product;
b) After formal production, if there are major changes in structure, raw materials,
and processes, which may affect product performance;
c) An inspection shall be conducted every six months during normal production;
d) When the product resumes production after a long-term suspension of production
for half a year;
e) When there is a big difference between the exit-factory inspection result and the
last Type inspection result;
f) When the national quality supervision agency requests for type inspection.
6.1.3 Appraisal inspection
Appraisal inspection items indicate all items in Clause 4. It shall be carried out when
the new product is trial-produced or when the quality of the product is disputed.
6.2 Batching and sampling
