_____________
1 Scope
Replace the second dashed list item, modified by Amendment 1, with the following new
dashed item:
– a SELV system without provision for protective earthing (class III) and a rated current not
exceeding 25 A per conductor, or
At the end of the scope, add the following new text:
This document does not cover operational or performance compatibility between different
track systems. Protection against unsafe compatibility between Class I and Class III circuit is
covered by this document.
The track system can be provided with auxiliary circuits for the purpose of a control or audio
signal other than supply.
NOTE 1 At present, the following types of control systems are available on the market:
– control signal, with basic insulation to LV supply (e.g. digital addressable lighting interface, 1 V to 10 V DC
signal);
– control signal, SELV/PELV insulated to LV supply (e.g. DMX);
– control signal, not insulated to LV supply (e.g. push button control/phase cut/step dim).
Track systems can also be provided with conductors specifically identified for emergency
lighting luminaires.
© IEC 2019
NOTE 2 Requirements for PELV are under consideration, pending modification in IEC 60598-1.
2 Normative references
Replace the reference to IEC 60598-1:1999 with the following new reference and note:
IEC 60598-1:2014, Luminaires – Part 1: General requirements and tests

th
IEC PRVC 60598-1:2019. This 9 edition provides a cross link between IEC 60598-1 and IEC 60570 for track
mounted luminaires.
Add the following new reference:

3 Terms and definitions
3.1
luminaire track system
Add the following notes to entry:
Note 1 to entry: The track system may be provided with auxiliary circuits for the purpose of a control or audio
signal other than supply; the track system may be used to supply luminaires where the control signals are injected
via supply conductors or a circuit connected to the supply via separated conductors (e.g. powerline).
Note 2 to entry: The track system may be provided with circuits identified to ensure battery recharge (for self-
contained emergency luminaires).
3.10
class I track
Add the following notes to entry:
Note 1 to entry: The track can be provided with auxiliary circuits for control or audio signals. These auxiliary
circuits can use conductors originally designed for mains supply.
Note 2 to entry: The track system can be provided with circuits identified to ensure battery recharge (for self-
contained emergency luminaires).
3.11
class III track
Replace the existing note with the following new note to entry:
Note 1 to entry: The track can be provided with auxiliary circuits for a SELV control or audio signals. These
auxiliary circuits can use separate auxiliary conductors or conductors originally designed for a SELV supply.
5 General test requirements
5.3
In the second paragraph, replace "the following items" with "items a) to i) as follows." and
replace the colon ":" after "class III sectors:" with a full stop. then add, before list item a), the
following new paragraph:
– 4 – IEC 60570:2003/AMD2:2019
© IEC 2019
For track systems with control interface and/or additional circuits, it is necessary to provide
samples of the different constructions (both with and without additional circuits); the same is
applicable for tracks designed to be used together with emergency luminaires.
6 Marking
In the first paragraph, replace "6.7" with "6.9".
6.1
In the second paragraph, replace "symbol for class III" with "graphical symbol
IEC 60417-5180 for class III".
6.3
At the end of the second paragraph, add the following new text:
All terminals shall be marked with their identification; the mounting instructions shall explain
the meaning of identification and the relevant circuit connections and/or functions.
NOTE Some track and adaptor terminals can be identified with a dual function such as for supply or audio signal
connection.
6.5
At the end of list item a), add the following new text:
If the track is intended to be wall mounted, or has similar non-horizontal mounting, the
instructions shall contain information regarding any limitations of the track positioning, and the
maximum specified mechanical loadings.
6.6
Replace list item b) with the following new item b):
b) where there is an associated safety isolating transformer or lamp controlgear, instructions
regarding the correct method of connection of the transformer or lamp controlgear
terminals to avoid misinterpretation of the primary and secondary terminals;
In list item d), delete the note.
At the end of list item e), add the following new item f):
f) a warning that for Class III track systems any connected control or audio signals shall only
be provided by a SELV source.

6.9 Marking for track suitable for supplying emergency luminaires
In addition to the above markings and information, the following details shall be given in the
manufacturer’s instructions:
• for track systems designed to operate centrally supplied emergency luminaires: a warning
that the track and components shall be connected to a system designed to supply
emergency luminaires, to ensure the correct operating of emergency luminaires on the
whole system;
• for track systems used to supply a self-contained emergency luminaire: information that
the supply line for battery recharging shall be un-switched.
7 General requirements and ratings
Replace the first sentence of the third paragraph, modified by Amendment 1, with the
following new text:
The rated voltage between poles for a class I track system shall not exceed 440 V and for a
class III system the rated voltage shall not exceed SELV voltage limits as specified in
IEC 60598-1.
8 Construction
Replace the first paragraph with the following new text:
The provisions of section four of IEC 60598-1 apply together with the requirements in 8.1 to
8.13 with the exception of 4.11.6 which is replaced by 8.9.

systems using control signals via conductors designed for supply voltage.
Compliance shall be checked by carrying out the tests in Annex A as applicable.
8.6
Replace the third paragraph starting with "To test the suspension…" with the following new
text:
To test the suspension of both track and luminaires, suspension devices for luminaires,
including adaptors, are mounted on the track as in normal use specified by the track
manufacturer and are subjected for 1 h to a load equal to 5 times the specified load as
claimed by the manufacturer. The minimum claimed load value for adaptor and for suspension
devices for luminaires shall be:
– 50 N for class I and class II;
– 10 N for class III;
– the weight of the luminaire for adaptors which are integrated in the luminaire.
NOTE The adaptors according to the third bullet are intended for use by luminaire manufacturers only and are not
for retail sale.
This test shall be made at a temperature of t of the track +15 °C.
