New Compliance Document Required for All USB PD Certifications
Mandate: Required
Effective Date: June, 2021

Effective Immediately all USB Power Delivery capable products seeking certification must test against the USB Power Delivery Compliance Test Specification Revision 1.2 Version 2, also known as the PD Merged Test Specification. This test specification combines the previously used USB PD 3.0 Tests document with the PD 2.0 Communication Engine MOI and PD 2.0 Deterministic MOI in addition to adding new checks that were not previously covered.

The list of approved equipment that use this document can be found here.

A grace period of 6 months will be given to products that fail the new compliance specification document while passing the old compliance specification documents. The waiver request must state any failures found using the new compliance specification document will be debugged. In addition, the waiver request must provide a reasonable fix date.

USB Authorized Test Labs, otherwise known as Independent Test labs, are instructed to run the new PD Merged Test Spec first then roll back to the old compliance documents if failures are found. The USB-IF will require that test labs submit results for both the old and the new versions of the compliance documents.
