7  Definitions—other expressions used in this instrument
Note 1: A number of expressions used in this instrument are defined in section 5 of the Act, including the following:
● category A product;
● covered by;
● family of models;
● GEMS;
● GEMS labelling requirements;
● GEMS level requirements;
● model;
● product classes
Note 2: Many of the following definitions are based on ILV (the International Lighting Vocabulary) or IEV-845 (the part of the International Electrotechnical Vocabulary that deals with lighting).  Where the definition of an expression below differs from the ILV or IEV definition, the definition in this instrument takes precedence.
  In this instrument:
Act means the Greenhouse and Energy Minimum Standards Act 2012.
Australian/New Zealand Standard means a standard that is jointly published by Standards Australia and Standards New Zealand, is applicable in both countries and denoted by the letters "AS/NZS" and identifying numbers and/or letters.
carbon filament lamp means a vacuum, or inert gas‑filled lamp, whose luminous element is a filament of carbon, housed in a glass envelope.
chromaticity coordinates means the x and y coordinates represented on the 1931 CIE colour space given in CIE 015.
general lighting services means substantially uniform lighting of an area without provision for special local requirements.
Note: This is the same meaning as in IEV-845.
incandescent lamp means a tungsten filament lamp or a carbon filament lamp or a tungsten halogen lamp.
initial values, for an incandescent lamp, means the photometric and electrical parameters of the lamp, measured after the initial ageing period.
lumen maintenance factor means the ratio of the luminous flux of a lamp at a given time in its operational life to the initial value of its luminous flux, the lamp being operated under specified conditions.
luminaire means an apparatus which distributes, filters or transforms the light transmitted from at least one source of optical radiation and which includes, except the sources themselves, all the parts necessary for fixing and protecting the sources and, where necessary, circuit auxiliaries together with the means for connecting them to the power supply.
luminous flux () means the change in luminous energy with time, as given by the following formula:
where:
Qv is the luminous energy emitted, transferred or received.
t is time.
median lamp life, for a model of a lamp, means the duration in operating hours after which 50% of a representative group of lamps have survived when operated under specified test conditions.
Note 1: This is often referred in product catalogues as "average lamp life".
Note 2: This is the same meaning as in subclause 1.3.6 AS/NZS 4934.1:2014.
product class 1 means the product class mentioned in item 1 of the table in section 13.
