Quality Control
A Precise Machine Cannot Be Built Without Strict Inspection
Feizhong has all domestic and overseas product quality certificates, Every process is strictly in accordance with GB/T19001-2023 management system to carry out and we also formulate rules in line with our own situation:
The operators of the production department are responsible for self-inspection and mutual inspection of their respective processes.
Self-inspection: The operators of each process shall conduct the inspection according to the items specified in Table 1. After the self-inspection is qualified, sign and approve in the column of "operator" of the corresponding process in the process flow card;
Mutual inspection:The next process'operator shall inspect the items specified in the reference table 1 of the previous process. If the mutual inspection is qualified, it shall be signed and approved in the special inspection "subsequent opinion" column of the previous process on the process flow card.

The technical department is responsible for the control and implementation of routine inspection and confirmation inspection of products.
1. Routine inspection is to inspect the products on the production line at the final stage of production. Usually, after the inspection, no further processing will be performed except for packaging and labeling.
2. Routine inspections of dehumidifier products shall comply with the provisions of the ""Implementation Rules for Compulsory Certification of Electrical and Electronic Products - Household and Similar Purpose Equipment"", specifically in accordance with the provisions of Schedule 1. Routine inspections are allowed to be carried out by equivalent and rapid methods determined after verification.
3. The technical department is responsible for organizing the inspection station to compile the ""Finished Product Inspection Specification"", specify the inspection items, sampling plan, inspection method, judgment basis, and use corresponding inspection equipment.
4. After the finished product and packaging quality inspection pass, the inspector fills in the ""Dehumidifier Finished Product Inspection Record"", and notifies the person in charge of the workshop and the finished product warehouse to handle the finished product storage procedures. Unqualified products are marked and stored separately.
Note: The product must be inspected item by item according to Table 1. If one item is unqualified, it will be judged as unqualified product. Dehumidifier products are packaged after passing the inspection according to the items in Table 1.

Confirmation Inspection
1. Confirmation inspection is a sampling inspection to verify that the product continues to meet the requirements of the standard, and the confirmation test should be carried out in accordance with the provisions of the standard.
2. The confirmation inspection of dehumidifier products shall comply with the provisions of the "Implementation Rules for Compulsory Certification of Electrical and Electronic Products for Household and Similar Purpose Equipment", specifically in accordance with the provisions of Schedule 2.
3. When confirming the inspection, if the factory does not have testing equipment, it can entrust a laboratory to conduct it. Confirm inspection items
If one of the items is unqualified, it will be judged as unqualified.
Inspection and Test Records
1. Both routine inspection and confirmation inspection records should clearly indicate the quality status of the finished product, that is, whether it is qualified or not.
2. All inspection records should be clear, complete, and true, with no blank columns allowed, and signed or stamped by authorized inspectors.
3. Inspection records shall be kept by the inspection station.
