This document provides criteria for the re-use of sulphur hexafluoride (SF6) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-oflife). Sulphur hexafluoride (SF6), nitrogen (N2) and carbon tetrafluoride (CF4), are gases commonly used for electrical equipment. Taking into account environmental concerns, particular attention is paid to re-use criteria for SF6 and its mixtures with N2 and CF4 for its use in electrical equipment. Procedures for recovering and reclaiming used SF6 and its mixtures are outside the scope of this document and are described in IEC 62271-4. This document provides several annexes on the description of the different methods of analysis, on by-products, on the procedure for evaluating the potential health effects from byproducts, on cryogenic reclaiming of SF6, and on reclaiming recommendations. Storage, transportation and disposal of SF6 and its mixtures are outside the scope of this document and are covered by IEC 62271-4. Procedures to determine SF6 leakages are described in IEC 60068-2-17 [4]1. For the purposes of this document, the complementary gases used in SF6 mixtures will be limited to N2 or CF4.

IEC 61800-9-2:2017 specifies energy efficiency indicators of power electronics (complete drive modules, CDM), power drive systems (PDS) and motor starters, all used for motor driven equipment. It specifies the methodology for the determination of losses of the complete drive module (CDM), the power drive system (PDS) and the motor system. It defines IE and IES-classes, their limit values and provides test procedures for the classification of the overall losses of the motor system. Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems. This depends on the architecture of the motor driven system, on the speed/load profile and on the operating points over time of the driven equipment.

This part of IEC 61347 specifies general and safety requirements for lamp controlgear for use
on d.c. supplies up to 250 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
This standard also covers lamp controlgear for lamps which are not yet standardized.
Tests dealt with in this standard are type tests. Requirements for testing individual lamp
controlgear during production are not included.
Requirements for semi-luminaires are given in IEC 60598-1:2014 (see definition 1.2.60).
Particular requirements for controlgears providing safety extra low voltage (from now on
SELV) are given in Annex L.
It can be expected that lamp control gear which comply with this standard will not compromise
safety between 90 % and 110 % of their rated supply voltage in independent use and when
operated in luminaires complying with the safety standard IEC 60598-1 and the relevant part
IEC 60598-2-xx and with lamps complying with the relevant lamp standards. Performance
requirements may require tighter limits.

electric/electronic circuits and their components in the electronic lamp controlgear, the
requirements of IEC 61347 series apply.

This International Standard specifies performance requirements for electronic controlgear for
use on a.c. and/or d.c. supplies up to 1 000 V and/or a.c. supplies up to 1 000 V at 50 Hz or
60 Hz, associated with discharge lamps, as specified in IEC 61167, which have information
for low frequency square wave operation, where the frequency range of the low frequency is
from 70 Hz to 400 Hz.
Tests in this standard are type tests. Requirements for testing individual controlgear during
production are not included.
There are regional standards regarding the regulation of mains current harmonics and
immunity for end products like luminaires and independent controlgear. In a luminaire, the
controlgear is dominant in this respect. Controlgear, together with other components, should
comply with these standards.

This part of IEC 61347 specifies particular safety requirements for electronic controlgear for
use on d.c. or a.c. supplies up to 1 000 V (a.c. at 50 Hz or 60 Hz) and at an output frequency
which can deviate from the supply frequency, associated with LED modules.
Controlgear for LED modules specified in this standard are designed to provide constant
voltage or current at SELV or higher voltages. Deviations from the pure voltage and current
types do not exclude the gear from this standard.
The annexes of IEC 61347-1 which are applicable according to this Part 2-13 and using the
word “lamp” are understood to also comprise LED modules.
Particular requirements for SELV controlgear are given in Annex I.
Performance requirements are covered by IEC 62384.
Plug-in controlgear, being part of the luminaire, are covered as for built-in controlgear by the
additional requirements of the luminaire standard.

This part of IEC 61347 specifies particular safety requirements for battery supplied electronic
controlgear for maintained and non-maintained emergency lighting purposes.
It includes specific requirements for electronic controlgear and control units for self-contained
luminaires for emergency lighting as specified by IEC 60598-2-22.
It is intended for controlgear for fluorescent lamps, but it is also applicable to other lamp types
e.g. incandescent, high pressure discharge lamps and LEDs.
This standard covers the emergency mode operation of a controlgear. For controlgear with a
combination of normal and emergency lighting operation, the normal lighting operation
aspects are covered by the appropriate part 2 of IEC 61347.
DC supplied electronic controlgear for emergency lighting may or may not include batteries.
This standard also includes operational requirements for electronic controlgear, which, in the
case of d.c. supplied electronic controlgear, are regarded as performance requirements. This
is because non-operational emergency lighting equipment presents a safety hazard. It does
not apply to d.c. supplied electronic controlgear for emergency lighting, which are intended for
connection to a centralised emergency power supply system. A centralised emergency power
system could be a central battery system.
NOTE Annex J of IEC 61347-2-3 applies to a.c., a.c./d.c. or d.c. supplied electronic controlgear for connection to
centralised emergency power supply systems that are also intended for emergency lighting operations from
a.c./d.c. supplies.
