IEC 61347-2-1:2024 specifies safety requirements for starting devices (starters other than glow starters and ignitors) for fluorescent and other discharge lamps for use on AC supplies up to 1 000 V at 50 Hz or 60 Hz which produce starting pulses not greater than 100 kV and which are used in combination with lamps and controlgear covered in IEC 60081, IEC 60188, IEC 60192, IEC 60662, IEC 60901, IEC 61167, IEC 61195, IEC 61199, IEC 61347-2-8 and IEC 61347-2-9.

IEC 62271-200:2021 is applicable to prefabricated metal‑enclosed switchgear and controlgear assemblies designed for:
– alternating current;
– rated voltages above 1 kV and up to and including 52 kV;
– service frequencies up to and including 60 Hz;
– indoor and outdoor installation.
The assembly can include air-insulated and/or fluid-filled compartments.
This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) clause numbering aligned with IEC 62271‑1:2017, including the adoption of the subclause names of Clause 3;
b) in Clause 3 specific definitions are added for "in service", "normal operating condition" and "normal use";
c) internal arc testing on pole-mounted switchgear is taken out of this document, as it is now covered by the specific standard IEC 62271‑214:2019;
d) a more precise description of earthing circuit is given with the inclusion of ratings and test requirements;
e) number of mechanical tests on interlocks is reduced for type testing; a more precise description of forces to apply during type testing is given (refer to 7.102);
f) resistance measuring on main circuit is only needed before continuous current tests (as reference for routine tests) and no longer needed after this continuous current test. Rationale for this deletion is that this measured resistance does not mean anything; as the temperature rise test was just finished, a new temperature rise test will not give new information;
g) IEC 62271-100:2021, IEC 62271-103:2021, IEC 62271-105:2021 and IEC 62271-106:2021 are referred to in the document;

j) examples not covered by the IAC test are transferred from Clause 6 to 9.103;
k) the term "assembly" is defined in Clause 3 and used as synonym for "metal-enclosed switchgear and controlgear" in this document;
l) "metallic" is replaced by "metal" where applicable;
m) 6.105 is now covered by 7.7;
n) a 1 s rule was introduced for Criterion 4 during IAC tests regarding hot gases versus glowing particles as cause of ignition;
o) a more precise description of internal arc tests for switchgear with protrusions is given in Annex A.

This part of IEC 61800, which is a product standard, specifies requirements and makes
recommendations for the design and development, integration and validation of safety-related
encoder (Encoder(SR)) in terms of their functional safety considerations, electrical safety and
environmental conditions. It applies to Encoder(SR), being sensors as part of a PDS(SR).
NOTE 1 The term "integration" refers to the Encoder(SR) itself, not to its incorporation into the safety-related
application.
This document can also be referred to and used for Encoder(SR) in any other safety-related
application, for example safety-related position monitoring.
NOTE 2 This document specifies only complementary functional safety, electrical safety and environmental condition
requirements that are not clearly provided by other parts of the IEC 61800 series.
This document is applicable where functional safety of an encoder is claimed and the
Encoder(SR) is operating mainly in the high demand or continuous mode.
NOTE 3 While low demand mode operation is possible for an Encoder(SR), this document concentrates on high
demand and continuous mode. Safety sub-functions implemented for high demand or continuous mode can also be
used in low demand mode. Requirements for low demand mode are given in IEC 61508 (all parts) [2]. Some guidance
for the estimation of average probability of dangerous failure on demand (PFDavg) value is provided in
IEC 61800-5-2:2016, Annex F.
The requirements of IEC 61800-5-2:2016 for PDS(SR) apply to Encoder(SR) as applicable. This
document includes additional or different requirements for Encoder(SR). It sets out safetyrelated
considerations of Encoder(SR) in terms of the framework of IEC 61508 (all parts), and
introduces requirements for Encoder(SR) as subsystems of a safety-related system. It is
intended to facilitate the realisation of the electrical/electronic/programmable electronic
(E/E/PE) and mechanical parts of an Encoder(SR) in relation to the safety performance of safety
sub-function(s) of an Encoder(SR).
Manufacturers and suppliers of Encoder(SR) will, by using the normative requirements of this
document, indicate to users (system integrator, original equipment manufacturer) the safety
performance of the Encoder(SR). This will facilitate the incorporation of Encoder(SR) into
safety-related control systems using the principles of IEC 61508 (all parts), and possibly its
specific sector implementations (for example IEC 61511 (all parts) [3], IEC 61513 [4],
IEC 62061 [5] or ISO 13849-1 and ISO 13849-2 (see Clause 2).
By applying the requirements from this document, the corresponding requirements of
IEC 61508 (all parts) that are necessary for an Encoder(SR) are fulfilled.
This document does not specify requirements for:
• the functional properties of an Encoder(SR) without any safety relevance;
• the hazard and risk analysis of a particular application;
• the identification of safety sub-functions for that application;
• the initial allocation of SILs to those safety sub-functions;
• the driven equipment except for interface arrangements;
• secondary hazards (for example from failure in a production or manufacturing process);
• the Encoder(SR) manufacturing process;
• the validity of signals and commands to the Encoder(SR); and
• security aspects (e.g. cyber security or Encoder(SR) security of access).
NOTE 4 The functional safety requirements of an Encoder(SR) are dependent on the application, and can be
considered as a part of the overall risk assessment of the installation. Where the supplier of the Encoder(SR) is not
responsible for the driven equipment, the installation designer is responsible for the risk assessment, and for
specifying the functional and safety integrity requirements of the Encoder(SR).
This document applies to Encoder(SR) implementing safety sub-functions with a SIL not greater
than SIL 3.
This document provides additional information for Encoder(SR) claiming
