EN IEC 60598-2-22 specifies requirements for emergency luminaires for use with electrical lamps on emergency power supplies not exceeding 1,000 V. It does not cover the effects of non-emergency voltage reductions on luminaires incorporating high-pressure discharge lamps. The text of IEC 60598-2-22:2021 has been approved in Europe as EN IEC 60598-2-22:2022 without any changes.
The main changes in the new edition are:
— update of requirements for rest mode and inhibiting mode,
— clarification of high-temperature operation tests,
— introduction of new requirements for lithium batteries and electric double-layer capacitors (EDLCs),
— clarification of resistance to heat, fire and tracking, test facilities for self-contained luminaires and a test method for contrast measurements of exit signs.
