6. Required Documents
1. Application submission: Relevant application forms
2. Documents for testing
(1) CB report, including Japanese national differences testing
(2) Circuit layout
(3) Safety-related PCB design drawings
(4) Specifications for transformers and coil components
(5) Critical component list and certificates
(6) Japanese instructions for use or assembly manual
(7) Japanese nameplate and warning labels, including the PSE mark and notifying supplier's name
(8) Construction data sheet
(9) Factory production equipment lists and calibration certificates for factory inspection
7. Sample Requirements
Sample requirements depend on the applicable standard and certification body. Typically, 5 samples are required with a CB report, or 10 without one.
8. Certification Process
1. The applicant provides the required documents.
2. Both parties sign the quotation contract.
3. The applicant sends samples.
4. The laboratory tests the samples.
5. Issue the certificate.
6. Send the report and certificate.
9. Certification Timeline & Validity
Circular PSE certification takes 2 weeks; diamond PSE certification takes 4 weeks.
Diamond PSE certificates are valid for 3, 5 or 7 years, depending on the product. Circular PSE generally uses a manufacturer's self-declaration or a test report issued by a third-party laboratory or certification body; there is no certificate or fixed validity period.
10. Factory Inspection
Diamond PSE certification: Initial factory inspection only; no annual review
Circular PSE certification: No factory inspection required
