Comparative Analysis of Proxy and Autonomous Applications

There are two main modes for enterprises to obtain the explosion-proof certificate: self-application and agency application, which differ significantly in cost, timeline, and technical requirements.

Self-application:

Advantage: Eliminates the need for agency service fees, suitable for large enterprises with mature explosion-proof design capabilities and familiarity with standard processes.

Challenge: Requires independently completing technical documentation preparation, prototype debugging, and communication with the laboratory. Insufficient understanding of the GB/T 3836 series standards can easily lead to repeated revisions, resulting in higher communication and time costs. ‌‌

Agent Application:

Advantage: The agency provides preliminary design modification guidance, document preparation, and schedule coordination, ensuring that the submitted samples and drawings comply with standard requirements, significantly improving the first-time pass rate. ‌‌

Efficiency: Professional agencies are familiar with the testing agency's procedures and can coordinate the testing schedule. Some cases show that agency applications can enter the evidence collection phase approximately 30 days to 4-6 weeks after signing the commission (depending on the product's complexity)
