a) when key production process updated, mainly changes on main raw material;

b) production resumed after production discontinued;

c) major mass accident occurred;

d) significant difference between previous type inspection;

e) when quality supervision agency required by law;

f) when user has special requirements.

6.3.2.3 Randomly extract and mix 2 samples from the factory inspection items to ensure that each sample contains 1,1,1,2-tetrafluoroethane not less than 1000 g. One sample is used as a sample for 4.4 refrigerant quality inspection, and the other is used as a backup sample.

6.4 Rules for determination

6.4.1 As technical requirements 4.1~4.3, if the inspection indicator of the tested sample is unqualified, it shall be re-examined twice from the same batch of products for re-inspection. The re-inspection results shall prevail. If the retest result is still exceeding the quality limit, the batch is determined as unqualified.

6.4.2 Technical requirements 4.4 refrigerant quality inspection items shall be carried out according to the comparison method of the repair value in GB/T 8170. If the test results do not meet the requirements of this Standard, it shall be re-extracted twice from the same batch of products for re-inspection. The result of re-inspection is that even if only one indicator does not meet the requirements of this Standard, the whole batch of products shall be unqualified.

6.4.3 The determination rules for exit-factory inspection and type inspection shall be the same.
