UFC 3-520-05 is a Unified Facilities Criteria document titled "Stationary and Mission Batteries," current as of 1 May 2015, with Change 2 effective 9 January 2020 [UFC 3-520-05].

The document provides design criteria for stationary battery installations and applications including power plant backup power, substations, and switching stations [UFC 3-520-05 Appendix B]. It establishes requirements for emergency eyewash and safety shower facilities (located within 20 feet of battery enclosures), electrical receptacle provisions for battery chargers, and references related standards such as ANSI/ISEA Z358.1 for portable emergency facilities [UFC 3-520-05 para 3-10 and 3-11].

UFC 3-520-05 is cross-referenced in DAFMAN 91-203 for lithium-ion battery storage and ventilation requirements [DAFMAN 91-203 para 29.3.2], and in nuclear weapons facility criteria as a mandatory design standard alongside UFC 3-520-01 and UFC 3-550-01 [FC 4-420-07F para 3-2.1].
