Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have an extensive portfolio of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and we offer services such as application assistance and factory audit guidance for this certification.
Requirements for materials needed to apply for the explosion-proof CCC certification:
1. Product drawings and documents: When an enterprise applies for a certification of explosion-proof qualification for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board diagrams, silk-screened diagrams, material lists for components, and label drawings, etc. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the explosion-proof performance of the sample (including assembly drawings and component drawings). If the overall drawing clearly indicates the explosion-proof parameters and structure of the product, only the overall drawing needs to be submitted for inspection.
2. Technical Documents: Include corporate standards/technical requirements. The corporate standards/technical requirements for the product should be written in the specified format, with content that not only covers performance requirements but also includes relevant aspects of explosion-proof: such as basic parameters, explosion-proof markings, environmental conditions for use, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
3. Additional Information: For products with adhesive bonding or casting, provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic casing products, provide the material and corresponding performance documents. Battery-equipped products require a battery specification sheet as well.
In July 2019, the market released an implementation notice concerning the conversion of explosion-proof electrical products, among others, from production license to mandatory product certification.
The announcement clearly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and domestic refrigerators with a rated capacity of over 500L will be included in the CCC certification management scope. Additionally, a transition period of 1 year is provided.
As of October 1, 2020, the above products have not obtained the mandatory product certification and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any business activities.
This means that in the future, companies applying for explosion-proof certification will be required to undergo CCC mandatory certification, and will be executed in accordance with the implementation rules of the CCC mandatory certification.
After the explosion-proof CCC certification has replaced the production license, is an explosion-proof compliance certificate still required?
Since the issuance of the market supervision regulations on explosion-proof electrical products, etc., in July 2019
Following the announcement of the implementation requirements for mandatory product certification management after the transition from production license to mandatory product certification.
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
Does the product need an explosion-proof certification to enter the market?
What are the additional conditions required for a company to produce explosion-proof electrical products?
In fact, just by carefully reading this announcement, you can understand that...
The notice only includes a portion of explosion-proof electrical products within the scope of mandatory product certification.
(For details, see the product catalog of the mandatory explosion-proof electrical product certification.)
A significant portion of explosion-proof products have not yet been included in the market.
For example, common pressure transmitters, flammable gas detectors, breathing valves, dust removal equipment, and mechanical products.
Extraneous explosion-proof equipment installed in explosive areas must strictly adhere to the requirements of the GB/T3836 series of explosion-proof standards.
Obtain the corresponding explosion-proof certification.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are divided into Explosion-proof 3C Certification and Explosion-proof Certificate Certification.
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products, belonging to different certification models.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products listed in the catalog undergo explosion-proof 3C certification, adopting the "Product Testing + Factory Audit" model.
Both product type tests and factory site audits are required.
Ex-proof certification is applicable to products not listed in the Ex-proof 3C Catalogue. The certification model is Product Testing; once the Product Testing is passed, an Ex-proof Certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for just the explosion-proof certification, but there's a risk of being penalized by market regulation. This is something for the customer to consider on their own. When inquiring, the customer should first confirm what type of product it is, and then decide on the certification model.
If you are unsure whether the product is included in the Intrinsic Safety 3C Catalog.
