a) Type inspection Randomly select two products that have passed the factory inspection as samples, and then divide them into two groups, A and B. Group A samples are inspected according to a), b), c), d), e), f), g), h) specified in 5.2.2. Group B samples are inspected according to i), j), k), l), m) specified in 5.2.2; b) If no major defects are found in the samples after type inspection, the product is judged to have passed this type inspection. If a major defect is found during the inspection, a second sampling is carried out and the type inspection is repeated. If no major defects are found, the product is still judged to have passed this type inspection. If the defect still exists in the sample taken for the second time, the product is judged to be unqualified for this type inspection; c) When the sample type inspection result fails to meet any of the requirements of 3.3 to 3.11, it is judged as having major defects d) If a sample fails during the inspection, it is allowed to be repaired. If the repair content has no effect on the inspection results of the items that have been inspected, the inspection can continue. Otherwise, the affected inspection items should be redone. 6 Marking, packaging, transportation, and storage
6.1 Marking
6.1.1 Each device must be equipped with a permanent and clear mark or nameplate in a prominent position of the chassis, marking the following contents a) Product model and name;
b) Full name and trademark of the manufacturer;
c) Main parameters;
d) External terminal and interface identification;
e) Factory date and number.
6.1.2 The packaging box should be marked with the following paint that is not easy to wash or fall off: a) the name of the shipping factory, product model, name; b) the name, address and destination of the receiving unit; c) the overall dimensions (length x width x height) and gross weight of the packaging box: d) the words "moisture-proof", "upward", "handle with care" should be written on the outside of the packaging box; e) the number of layers should be specified on the outside of the packaging box. 6.1.3 Signs and identifications should comply with the provisions of GB191. 6.1.4 The standards implemented by the product should be clearly stated. 6.1.5 The safety design mark should be clearly stated in accordance with the provisions of GB16836. 6.2 Packaging3b)
