Data Management
The publication of ISO 19650 set of standards replaces use of PLQ and instead introduce the term with exchange information requirements (EIR) and project information requirements (PIR).
Project information requirements (PIR)
PLQ and PIR are both expressions of the high-level information needed by the client and/or their stakeholders to make key decisions concerning the project. The PIR, like the PLQ, are used to develop the detailed and contractual EIR. However, PIR can also include non-technical requirements and therefore can be broader than PLQ.

BS 7671:2018+A2:2022, specifically Section 560: Safety Services
BS 8519:2020, with emphasis on Clause 7 (Cable Routing) and Clause 11 (Cable Selection)
The goal: clarify requirements for the diverse cable routing and maintain circuit integrity under fire conditions for systems that support life safety and fire-fighting applications, such as sprinkler pumps, fire-fighting lifts, and smoke control systems.
