Updated from AS 2293.3:2005 to AS/NZS 2293.3:2018.

Changes in this edition of the Standard include the following:
(a) Introduction of requirements for alternative light sources (i.e. LED) and allowance for
the use of emerging battery technologies.
(b) Inclusion of New Zealand requirements (for publication as AS/NZS Standard).
(c) Updated references to new pictogram standards.
(d) Added definition and requirements for dual function exit signs.
(e) Replacement of AS 3137 with AS/NZS 60598.2.22.

Some details:
1.     Dual function exit signs shall firstly comply with all the requirements of the subsequent clauses 3.3 and 3.4 of this Standard in order to then be classified as an emergency luminaire.。
 
2.     All emergency luminaires and exit signs shall comply with AS/NZS 60598.2.22 unless otherwise varied in this Standard.
 
3.    Specific requirements relating to Clauses F6 and F8 of the New Zealand Building Code have been added where it is necessary to alter clauses of this Standard to comply with New Zealand requirements.
   
4.    Additional requirements of marking：
    a)    Where combined or sustained emergency luminaires are used, the location of the emergency light source shall be clearly marked, together with any information necessary to ensure correct light source replacement.
    b)    Designed mounting positions and orientation (related to luminaire position/ safety IP rating, etc.). This information shall be marked on the luminaire to enable identification of the classification for each mounting position.  
    c)    For LED exit signs the body shall also be marked with the Projected Light Source Life.
 
5.     Add new clause for particular requirements for centrally supplied emergency  luminaires and exit signs。
 
6.     New test requirement:
  a)    Glare limitations：
 In order to restrict disability glare at higher angles, limitations are applied to the luminous intensity of the luminaire based on the mounting height range in accordance with Table C1.

 b)    Colour temperature and colour rendering index：
 The colour temperature shall fall with the range from 2500 K to 7000 K.
The minimum value of the colour rendering index Ra of the light source utilized in any emergency luminaire shall be greater than 40.
 
c)    LED:
measure LED Ts temperature and operating current at 40.  

d)    PROJECTION OF LIGHT SOURCE LIFE (LSL) IN LED EXIT SIGNS:
LM-80 test report for LED should be provided and LM-80 data for the LED being assessed,based on IES TM-21,calculate the life of LED exit signs.
