Unless otherwise specified, all inspections shall be carried out under the conditions specified in 3.1~3.4 of GJB150.1. 4.4 Identification inspection
Identification inspection must be carried out in a laboratory approved by the equipment ordering party or the local identification agency. Identification inspection shall be carried out when the product is designed and finalized for production. 4.4.1 Inspection samples
The samples subjected to identification inspection are randomly selected from the radar batch to be identified. Unless otherwise specified, generally not less than two. 4.4.2 Inspection items
Unless otherwise specified, the identification inspection items shall be carried out in accordance with Table 2. The inspection items may also be increased or decreased through consultation between the radar contractor and the ordering party.

If all the inspection items meet the requirements of the specification, it is still judged as qualified for the identification inspection; if there is still an item that does not meet the requirements of the specification, it is judged as unqualified for the identification inspection. 4.4.4 Maintenance of Qualification
To maintain the qualification of radar appraisal, the contractor shall provide radar test data regularly according to the requirements of the ordering party or the superior appraisal agency.
