System design, installation and operation.
The objective of this Standard is to provide designers, installers and certifiers of emergency lighting and exit signage schemes with the relevant requirements and guidance for the provision of emergency lighting and exit signs to all designated spaces within a building. This is to ensure an acceptable level of illumination for the safe evacuation of occupants from those spaces in an emergency situation. The principal reason for this edition of the Standard is to specify updated installation requirements and adapt the Standard to current technologies, terminologies and delete out of date references or methods.
Many of the section headings have been re-worded to reflect their application better and the sections re-ordered to assist in the reading of the document. Spacing tables have been moved to a normative appendix. Further to these 22933.1, some other definitions have been revised to support these new definitions or to clarify previous ambiguities.
This series of Standards do not cover items iii and iv. However, definitions for these types of lighting are included in this edition of the Standard.

22993.1 Some clauses have been moved to assist reading and application of the Standard. The clause specifying the illumination requirements has been moved to Clause 4. The calculations for the classification currently do not assess the contribution of luminance beyond this degree geometric limit.
Further, with changing technology, unlike fluorescent and incandescent types typical of the available light sources at the time of publication of previous editions of this standard, some luminaries including modern LEDs do not produce light beyond their assessed geometric imitation and therefore may not achieve at the current minimum 22293.1 all points on the floor. Two sets of tables are contained within Appendix E and F.

Appendix E contains tables based on 0. The use of spacing tables for stairwells has been revised and simplified. Rather ad modifying spacings using a set of rules, to achieve the higher illumination levels required in stairs, and spacing tables based around 0.
Provisions and requirements for centrally supplied systems have been simplified and upgraded.
Within buildings required to be constructed of fire-resisting ax, there are no longer separate provisions for buildings supplied with automatic sprinkler systems compared to buildings without. The class of cable protection has been standardised to be WS4X 22931, and the fuse type within terminal boxes has been widened to include fuses of a higher grade than type gG making it easier the match the fuse with a ceramic fuse holder, as required in the Standard.
This Standard distinguishes between documents cited as normative references and those referenced for information only.
