What test items are required to apply for an explosion-proof certificate?
Explosive-proof products require passing relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certification.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know what testing items are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Below, we'll give an example of common explosion-proof testing items.
For example, safety-integrity products typically include tests such as appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, and more.
Flameproof products mainly undergo tests including heat and cold resistance, internal ignition without propagation of explosion, shell pressure resistance, IP testing, and temperature rise testing, among others. Different testing items,
Each test item is designed to ensure that different modules or components of the product meet explosion-proof standards and fulfill the performance requirements for explosion-proof capabilities.
If a company is designing explosion-proof products and is unaware of the explosion-proof standards requirements,
ZhongNuo Inspection offers guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design essentials, drawing guidance, and offering agency services for explosion-proof testing and certification.

In July 2019, the market issued an implementation notice regarding the transition of explosion-proof electrical products and other categories from production licensing 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 volume 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 the CCC mandatory certification, and will operate in accordance with the implementation rules of the CCC mandatory certification.

How can a company apply for a防爆CCC certification?
1. Self-Application: Companies apply directly to the certification body, independently prepare relevant documents, assist in debugging prototypes, and modify any non-standard parts in the documents. This process is relatively time-consuming with a higher overall cost, requiring both time and effort.
2. Agent Application: The application process involves a specialized explosion-proof electrical technology consulting service agency (such as Shenzhen ZhongNuo Inspection Technology Co., Ltd.) handling the entire consultation and application process, including material modifications, prototype debugging, and progress coordination. The progress is well-guaranteed. Fast certification, controllable overall costs, time and labor-saving.
