Type inspection shall be performed in one of the following cases:
a) trial model identification for new product;
b) great changes in structure, material, technique after official production
which may affect product performances;
c) not less than once two years for batch- or mass-produced sensors;
d) production resumed after discontinued production of sensor for more than
one year;
e) great difference between exit-factory inspection results and previous type
inspection results;
g) required by national quality supervision organization.
6.3.2 Sampling and grouping
The sample for type inspection shall be extracted from the same batch of
samples that have passed exit-factory inspection and have been inspected as
accepted. The quantity must not be less than 12. Re-inspect according to the
exit-factory inspection items first. After they are inspected as accepted in re-
inspection, divide the samples into 4 groups equally. Carry out the test
according to the following grouping and item sequence.
Group 1: temperature test, temperature/humidity combination cycle test,
vibration test;

All the type inspection items for the sensor shall meet the requirements of the
regulations. If one item fails, re-extract double number of samples to re-inspect
the failed item. If it still fails, this batch of samples shall be determined as
rejected. But if the durability test fails, it shall not re-extract sample. Directly
determine it as rejected.
