== Certification and Test Tools ==
O-PAS certification is due to launch in Q4 of 2024.
The certification program requires third party verification for each O-PAS Profile. This must be done by O-PAS Recognized Verification Labs. The exceptions to this rule are for those requirements that involve other certification bodies. The OPC UA Connectivity Profile (OCF-001) and Global Discovery Service (GDS-001) are two profiles that must be verified by the OPC Foundation.
In June 2024, the [[OPC Foundation]] announced availability of verification for OCF-001 and GDS-001 O-PAS profiles in the OPC UA Profile Reporting Application.<ref>{{Cite web |title=Compliance Corner – June 2024 – OPC Connect |url=https://opcconnect.opcfoundation.org/2024/06/compliance-corner-june-2024/ |access-date=2024-06-29 |website=opcconnect.opcfoundation.org}}</ref><ref>{{Cite web |title=ProfileApplication |url=https://profiles.opcfoundation.org/profile/2089 |access-date=2024-06-29 |website=profiles.opcfoundation.org}}</ref>
Each Profile requires the SEC-F-001 Security Facet. This facet is derived from the ANSI/ISA-62443-4-2 SL2 security requirements. In order to verify this facet, the supplier must use an [[ISASecure]] Lab<ref>url=https://isasecure.org/certification/certify-now</ref>. In August 2024, the forum selected ISASecure as the exclusive verification provider for security requirements<ref>{{Cite web |title=The Open Group Open Process Automation Forum (OPAF) Selects ISASecure as Exclusive Verification Provider for Cybersecurity Requirements in the O-PAS Standard |url=https://isasecure.org/news-events/the-open-group-open-process-automation-forum-opaf-selects-isasecure-as-exclusive-verification-provider-for-cybersecurity-requirements-in-the-o-pas-standard |access-date=2024-08-13 |website=isasecure.org |language=en}}</ref>.
