III. PSE Certification Document Preparation
1. Application Submission Documents: Relevant application forms
2. Test Preparation Documents
(1) CB Report (including's difference test)
(2) Layout
(3) PCB design drawings related to safety standards
(4) Specifications for transformers and coil components
(5) List critical components and their certificates
(6) Japanese user manual or assembly manual
(7) Japanese nameplate and warning labels (including PSE mark and notified body name)
() Structural data sheet
(9) Factory production list and calibration certificates, etc. (for factory inspection)
3. Test Samples Provided: Depending on the application standards and certification, typically 5pcs are provided if there is a CB report, and 10pcs if there is no CB report.

2. Testing
Sample submission: The enterprise prepares qualified samples (usually 2-3 units) as required by the certification body and sends them to the GTS laboratory; specific sample requirements are with the laboratory.
Full testing: The laboratory conducts standard testing based on the corresponding national standards for the product (such as electrical safety, EMC electromagnetic compatibility, wireless performance, etc and issues a type test report.
Rectification and retesting: If the test fails, the enterprise must rectify the product and resubmit samples for retesting until the test passes
