How can certified enterprises realize the consistency control of CCC certified products
Date：2022/5/17 Clicks：637
How do you ensure compliance requirements are met?
Earlier, we discussed the conceptual understanding, judgment and inconsistency of the consistency of CCC certified products. For certified enterprises, in order to be honest and trustworthy, how to effectively implement the consistency control of CCC certified products to ensure that the products produced are Does the product meet the certification conformance requirements?
CNCA document requirements
The second paragraph of Clause 3.9 "Change and Consistency Control of Certified Products" in the "Requirements for Factory Quality Assurance Capability in the Implementation Rules for Compulsory Product Certification" (CNCA-00C-005) issued by the National Certification and Accreditation Administration has clearly stipulated: "Factory Product consistency should be controlled from applicable quality links such as product design (design changes), processes and resources, procurement, manufacturing, inspection, product protection and delivery, to ensure that products continue to meet the requirements of the certification basis."
The above paragraph summarizes the control points for achieving product consistency. In order to achieve the consistency of the final product, the management control requirements of the enterprise are not limited to a certain link, but run through all stages of the entire product manufacturing process. Below we briefly analyze the key points of enterprise management from the whole process of product manufacturing.
1. Product design stage
After applying for certification, the list of key components and product structure of the finalized product will constitute the important content of the basis for the consistency of the certified product, and cannot be changed at will without the approval of the certification body.
For the finalized product after design confirmation, its output document should specify key component suppliers, model specifications and production process requirements
In the product design and development stage, enterprises should clearly regard the national mandatory standard requirements related to product safety as the primary condition for design and development, and cannot relax the consideration of standard requirements just to meet the needs of the market and customers.
Q: Why should the output document of the finalized product after design confirmation specify the supplier of key components, model specifications and production process requirements?
A: The first is to reduce the risk of subsequent changes caused by the irreplaceability of suppliers or the unstable quality of parts;
The second is to reduce the risk of inconsistent product structure due to uncontrollable production processes.
2. the allocation of technology and resources
After the product is finalized, the factory should produce according to the process requirements of the design output, and prepare the corresponding resources, including production testing equipment, personnel in each position, and the environment required for production, etc., with the basic conditions for product consistency control.
For example, in the design and output of wire products, the processes are respectively purchasing copper rods, then drawing, annealing and then twisting, and directly purchasing copper wire conductors, and the preparations for incoming inspection equipment and production process equipment are completely different.
3. Procurement Control
Purchasing control is a key link in the consistency control of key components
At the same time, for enterprises with multiple certificates and multiple products, attention should be paid to the versatility of key components to reduce management costs and opportunities for errors.
The determination of the supplier list, the release of the purchase order and the purchase and storage are all aspects of product consistency control.
Enterprises should first ensure that the key parts in the product BOM are in one-to-one correspondence with the key parts list in the product description in the type test report.
4. Manufacturing control
Control key parts in the production picking process
The production process links control the product structure.
The key process links must have certain control measures.
Detailed explanation
When controlling the product structure in the production process, pay attention to the timely clearance of the production site to avoid misuse of key parts of the same type but different specifications;
The key process links must have certain control measures, such as the use of model management, regular inspection of production equipment parameters, and monitoring of key control parameters.
5. Inspection control
The inspection and control link is to avoid accidental errors in the production process resulting in inconsistent products.
Enterprises should carry out inspection and control at appropriate links in a targeted manner according to the complexity of the product. For example, the first article inspection of mass production, the mutual inspection of upper and lower processes, patrol inspection, batch inspection, etc., each inspection method and inspection content are aimed at different focus points.
6. Product protection and delivery control
In order to avoid product inconsistencies in delivery due to improper control of packaging, storage and transportation processes
Enterprises should set appropriate packaging protection requirements for products according to different product characteristics and delivery methods.
7. product change control
No product can remain the same, and companies will make changes based on market demand, changes in suppliers, and cost adjustments.
Enterprises should adopt appropriate change control in accordance with the requirements of certification rules, such as applying to certification bodies, or filing through simplified procedures.
The basis for the change is that the changed product should still meet the corresponding product standard requirements.
Conclusion
Regardless of the size of the enterprise and the complexity of the product manufacturing process, the certified enterprise should, according to the actual situation of the enterprise management, closely adhere to the basic principles of product consistency requirements, grasp the key link of product consistency control, and flexibly use the enterprise according to local conditions. Management means to achieve the ultimate goal of product consistency control and ensure that the certified products sold from the factory meet the certification consistency requirements.
