The following points should be noted when applying for a China Ex Certificate:
Product's Ex Marking: First of all, it is necessary to confirm the product's Ex marking, which is the target explosion-proof grade for product evalsuation. If it has not been determined yet, you can provide us with the product's application site, installation method or product manual for us to conduct a preliminary evalsuation of the Ex marking for you.
Cooperation in Product Rectification: During the application for a China Ex Certificate, if the product is still in the design stage or needs rectification based on the original ordinary product, we can provide full-process technical guidance and assistance in compiling certification documents to ensure that you can obtain the China Ex Certificate efficiently and effortlessly.
Samples and Drawing Documents: Applying for a China Ex Certificate requires the submission of product samples and complete design drawing documents. This will be relatively easy if you are the designer or manufacturer; additional efforts may be needed to prepare these documents if you are the purchaser or user.
Certification Acquisition Cycle: Confirm whether expedited processing is required and if there is a target date for obtaining the certificate.
Required Documents:
(1) Product manual and enterprise standard
(2) Design drawing documents
(3) Samples and sample blocks (provided in accordance with specific requirements)
Application Process:
(1) Collect and sort out the above-mentioned required drawing and technical documents.
(2) Conduct a preliminary evalsuation and confirm the certification plan.
(3) Reach a cooperation intention and sign a contract between both parties.
(4) STS will conduct a technical evalsuation of your product to ensure that the product and its drawings meet the requirements of explosion-proof standards.
(5) Arrange sample delivery for testing or on-site testing.
(6) Issue the explosion-proof test report and draft certificate.
(7) Grant the official China Ex Certificate.
In addition, for the application of a complete machine China Ex Certificate, all electrical components of the whole machine are required to be purchased and installed with explosion-proof certified components. For example, solenoid valves, control buttons, control cabinets and various sensors on the equipment must all have valid China Ex Certificates, and the installation method of each component must comply with the requirements of GB/T 3836.15-2017 Explosive atmospheres - Part 15: Design, selection and installation of electrical installations.
It is worth noting that there are currently multiple certification bodies in China authorized to issue China Ex Certificates, and the certificates issued by each body have equal legal effect.
