I'm assuming you are referring to an ISO standard for physical security. Considering that, please note that physical security is a broad topic (e.g., from the protection of facilities to protection of credit card readers), so without further detail is not possible to give you a more precise answer.
What I can tell you is that most of ISO standards related to physical security are related to Information Technology (e.g., ISO/IEC TS 30104:2015 Information Technology — Security Techniques — Physical Security Attacks, Mitigation Techniques, and Security Requirement, ISO/IEC TS 22237-6:2018 Information technology — Data center facilities and infrastructures — Part 6: Security systems, and ISO/IEC NP 24383 Information technology — Physical network security for the accommodation of customer premises cabling infrastructure and information technology equipment)
