not be deformed to such an extent that safety would be impaired and the suspension device
shall not have become loose.8.11
Replace existing Subclause 8.11 with the following new Subclause 8.11:
8.11 Interchangeability
8.11.1 Care shall be taken in the design and manufacture of adaptors for use with a
particular track system to ensure interchangeability and safety in use. In particular, no
connections between live conductors and earth conductors shall be possible.Tests shall be conducted with approved track samples retained by the test house or samples
of the approved track provided by the manufacturer.The minimum insulation between supply circuits (LV, SELV) and the housing and
control/signal interface shall be at least those specified in IEC 60598-1.
SELV circuits shall not use conductors designed for mains supply; this restriction also applies
to control signal and audio circuits which may be provided from a SELV source.SELV circuits shall comply with the requirements for Class III track.
Track conductors designed for the supply connection to luminaires may be used for other than
SELV control signal purposes if the insulation for those conductors meets the requirements
for relevant mains supply voltages.It shall not be possible to reduce the minimum creepage distances and clearances between
different circuits, as specified in IEC 60598-1, neither along the track, nor inside the
components. This requirement shall be ensured even in the case of connection of different
adaptors/components with different purposes of the same manufacturer in the track body, with
the only exception of track using control signals via conductors originally designed for mains
supply and marked accordingly.The track and adaptor shall comply with all appropriate parts of IEC 60598-1.
8.11.2 The opening in the insulating liner of a class I track/track sector giving access to the
conductor shall have a maximum dimension of 3,0 mm and the conductor shall be recessed
into the insulating liner by at least 1,7 mm.The contacts of class III adaptors shall either:
• have a minimum dimension of 3,5 mm in any orientation that can be presented to the
conductor opening in the insulating liner of any class I track sector, or---------------------- Page: 8 ----------------------
IEC 60570:2003/AMD2:2019 – 7 –
© IEC 2019
• the contacts shall not protrude by more than 1 mm from a surface that has a minimum
dimension of 3,5 mm in any orientation that can be presented to the conductor opening in
the insulating liner of any class I track/track sector (see example in Figure 4).
NOTE 1 This second requirement ensures, by requiring maximum protruding dimension of 1 mm, that there is no
electrical contact between the contacts of class III adaptors and the mains voltage conductors (being recessed by
at least 1,7 mm).NOTE 2 For clarity, the dimensions of the class I tracks and the class III adaptor contacts are measured in the
positions shown in Figures 2, 3 and 4.Compliance is checked by measurements.
The opening in the insulation liner of the track system giving access to the control interface
conductor of the following type:– control signal, with basic insulation to LV supply,
– control signal, not insulated to LV supply
shall comply with the requirements of 8.11.2 for Class I tracks.
The opening in the insulation liner of the track system giving access to the SELV control
interface conductor shall comply with the requirements of 8.11.1 for Class III tracks with the
exception of the minimum dimension that can be reduced.NOTE 3 For clarity, the dimensions of the class I tracks and the class III adaptor contacts are measured in the
positions shown in Figures 2 and 3.Compliance is checked by inspection and measurements.
8.12
Replace existing Subclause 8.12 with the following new Subclause 8.12:
8.12 Track systems designed to supply emergency lighting luminaires shall prevent any
accidental disconnection (in accordance with 22.11.1 of IEC 60598-2-22:2014 andIEC 60598-2-22:2014/AMD1:2017).
Track adaptors and luminaire suspension devices to be used with emergency luminaires
which are intended to be used for a display lighting application, shall include a system for
locking the luminaire in a fixed aiming direction and fixed position on the track. The locking
system shall ensure that the luminaire can be locked in its final aiming position and location
and that it cannot be adjusted or moved without the aid of a tool, and the emergency lighting
function of the luminaire cannot be switched off without the aid of a tool.NOTE A display lighting application is normally within arm reach.
Add, at the end of 8.12, the following new Subclause 8.13:
8.13 A track system used for centrally supplied emergency lighting shall provide double or
reinforced insulation between the conductors of the emergency lighting circuit and the normal
mains circuit.The working voltage to be used to design the insulation between different circuits shall be the
higher rated voltage of the different circuits.In a track system for centrally supplied emergency lighting, terminals identification shall
always be consistent within the entire system.---------------------- Page: 9 ----------------------

9 Creepage distances and clearances
In the first paragraph, replace "9.1 and 9.2" with "9.1 to 9.3".
At the end of Subclause 9.2, add the following new Subclause 9.3:
9.3 For Class I track systems it shall be ensured, by design, that any access to live parts
closer than the values given in Table 11.1A of IEC 60598-1 for reinforced insulation is
prevented.Compliance is checked by measuring the distance between live parts and a metal foil pressed
into any openings of the fully assembled track system with the probe 1 of IEC 61032:1997
(50 mm sphere) in every possible direction.11 External and internal wiring
Replace the second and third paragraphs with the following new paragraph:
If a supply cable is provided, the cross-sectional area of the conductors shall be compatible
with the rated current of the track system.13 Protection against electric shock
In the first paragraph, delete the text: ", except where the track system/sector openings is
classified class III for operation from a SELV supply".13.1
Add, between the first and second paragraphs, the following new text:
The test shall not be carried out on:
• SELV circuits;
• circuits with at least basic insulation to LV.
15 Insulation resistance and electric strength
15.2
Replace the existing text with the following new text:
Track systems that comply with the requirements of this document, are deemed to comply
with the provisions in 10.3 of IEC 60598-1 without testing.18 Terminals and connections for external wiring
In the first paragraph, correct the cross references to IEC 60598-1 as follows:
Replace "15.9.1" with "15.6.3.1", and replace "15.9.2" with "15.6.3.2".
For the subsequent sub-headings of Clause 18 correct the cross references to IEC 60598-1

Annex A
(informative)
Test to be carried out on luminaires supplied
with track systems providing control signals
The possibility to establish an unsafe connection between supply conductors and control
signals shall be prevented by the track system construction or by the luminaire.Unsafe connection may be prevented by a special mechanical key in the track system design
or, in the case of a track system using control signals via supply conductor, by having an
adequate protective measure in the luminaire such that any unintentional contact from the LV
supply to the control circuit will not cause a safety failure in the luminaire.Compliance is checked by the following tests:
In the case of a track system using a mechanical key system to prevent an unsafe connection,
no additional requirements apply to the luminaire.In all other cases the following requirements shall be applied to the luminaire.
The luminaire shall not become unsafe when the highest possible supply voltage is applied
between control signals contacts until steady state condition is reached.During and after the test there shall be no emission of flames or molten material from the
luminaire or production of flammable gases. The protection against contact to live parts shall
not be impaired. Insulation shall be adequate to exposed parts of the luminaire and checked
by the electric strength and insulation resistance tests as required in section ten of
IEC 60598-1.NOTE This requirement is considered sufficient as, in the case of basic insulation failure (wrong connection
between adaptor and track system), the supplementary insulation based on working voltage equal to the rated
luminaire supply voltage provided is considered sufficient.___________
