Compulsory Specification for Energy Efficiency and Functional Performance Requirements of General Service Lamps (GSLs) - VC 9110

2. Definitions

 

2.1 For the purposes of this document, the definitions in standards referred in Section 4 of this compulsory specification, shall apply.

 

2.2 In addition, the following definitions shall apply:

 

2.2.1 applicant: the manufacturer or importer seeking approval for GSL(s). The applicant shall be an existing legal entity within the Republic of South Africa.

 

2.2.2 approval: confirmation by the NRCS that a particular GSL(s) satisfies the requirements of this compulsory specification.

 

2.2.3 arithmetical mean: the average of a set of numerical values, calculated by adding them together and dividing by the number of terms in the set.

 

2.2.4 declaration report: a report that is issued by an accredited conformity assessment body, indicating the equivalence of standards.

 

2.2.5 directional lamp (DL): a lamp which has a beam angle (as defined in IEC 61341:1994 and measured in accordance with CIE S025:2015) of no more than 90 degrees in at least one plane and that being in at least one plane for an asymmetric beam lamp. These lamps are also known as reflector lamps and are commonly installed in recessed cans or track lighting.

 

2.2.6 family: a group of lamps, luminaires, light modules or drivers with the same brand name that has essentially identical: (1) physical characteristics and construction, (2) system design and performance, and (3) quality and safety characteristics. Any variation within a family of models shall have little or no effect on the efficacy and performance of those models.

 

2.2.7 fluorescence or fluorescent light source (FL): the phenomenon or a light source using an electric gas discharge of the low-pressure mercury type in which most of the light is emitted by one or more layers of phosphors excited by the ultraviolet radiation from the discharge. Fluorescent light sources may have one ('single-capped') or two ('double-capped') connections (‘caps’) to their electricity supply. For the purposes of this Regulation, magnetic induction light sources are also considered as fluorescent light sources.

 

2.2.8 gas discharge: a phenomenon where light is produced, directly or indirectly, by an electric discharge through a gas, plasma, metal vapour or mixture of gases and vapours.

 

2.2.9 general service lamp (GSL): includes a light source that meets the requirements of Section 1.1 of VC 9109.

 

2.2.10 halogen lamp: gas-filled lamp containing halogens or halogen compounds, the filament being of tungsten.

 

2.2.11 high-intensity discharge: ‘high intensity discharge’ (HID) means an electric gas discharge in which the light-producing arc is stabilised by wall temperature and the arc chamber has a bulb wall loading in excess of 3 Watts per square centimetre. ‘Gas discharge’ means a phenomenon where light is produced, directly or indirectly, by an electric discharge through a gas, plasma, metal vapour or mixture of gases and vapours. For the purpose of this Regulation, HID light sources are limited to metal halide, high-pressure sodium and mercury vapour types.

 

2.2.12 incandescence: emission of optical radiation by the process of thermal radiation. In light sources, incandescence is typically produced by the passage of an electric current through a threadlike resistive conductor (‘filament’) which creates heat.

 

2.2.13 lamp: a light source made in order to produce an optical radiation, usually visible. Note: The term "lamps" is often referred to as a globe, bulb or light bulb.

 

2.2.14 lamp cap: that part of a lamp, which provides connection to the electrical supply by means of a lampholder or lamp connector and, in most cases, also serves to retain the lamp in the lampholder.

 

Note 1: The term base is also used in both the United Kingdom and the US to denote an integral part of a lamp envelope, which has been so shaped that it fulfils the function of a cap. It may engage either a holder or a connector, depending on other design features of the lamp- and holder system.

 

Note 2: The cap of a lamp and its corresponding holder are generally identified by one or more letters followed by a number, which indicates approximately the principal dimension (generally the diameter) of the cap in millimeters.

 

2.2.15 light emitting diode (LED): a technology in which light is produced from a solid state device embodying a p-n junction of inorganic material or organic material. This latter case is also known as ‘organic light emitting diode’ (OLED). In both cases, the junction emits optical radiation when excited by an electric current.

 

2.2.16 luminaire: an apparatus which distributes, filters or transforms the light transmitted from one or more lamps and which includes, except the lamps themselves, all the parts necessary for fixing and protecting the lamps and, where necessary, circuit auxiliaries together with the means for connecting them to the electric supply.

 

2.2.17 model: refers to all the units in a product line from the same manufacturer, sold under the same brand name, and which are identical except for a serial number or other identifying mark. Any variation within a product line of models shall have no effect on the efficacy and performance of those models and shall only be due to natural manufacturing variation observed within otherwise identical units.

 

2.2.18 non-directional lamp (NDL): a general service lamp that is not a directional lamp.

 

2.2.19 NRCS: National Regulator for Compulsory Specifications as established by the National Regulator for Compulsory Specifications Act, 2008 (Act No. 5 of 2008).

 

2.2.20 proof of approval: a Letter of Authority (LoA) issued by the NRCS, which confirms that a particular GSL(s) satisfies the requirements of this compulsory specification.

 

2.2.21 valid test report: a copy of an original test report.
