What are the requirements for samples when applying for an explosion-proof certificate for electrical equipment?

Application for Explosion proof Certificate (Domestic Explosion proof Certificate)/ATEXauthentication/IECExThe requirements for samples in certification are basically the same, both requiring finished products2-3One; If it belongs to a large explosion-proof electrical system, because it contains many components and has a relatively large volume, for the enterprise, only one sample needs to be prepared. However, for electrical equipment with special components, separate special components need to be provided for related purposesExplosion proof testing.

1. The transparent part of the observation window will be sent separately5piece(at least3piece)The plastic transparent parts of the lighting fixtures will be sent separately8piece(at least5piece)；

2. The sealed parts must be sent with a set of intact sealed partsExmA set of components;

3. Rubber material aging test must be provided35×15×6Rubber block3～5Block;

4. Measurement of insulation resistance of plastic casing must be provided100×4Plastic sheet3～5Block. If the size allows, the plastic shell of the sample can also be directly measured;

5. As fornType or sealed type, required3～5For the sample of the casting type, additional parts before casting need to be provided; If there are transparent parts, they need to be provided3Block; Sample blocks are required for the commissioned surface resistance test≥150×60×3mmSpecial disassembly tools are also required for those with special processes.

6. If the product is equipped with a battery, a specification sheet for the battery is also required.
