technical revision. The essential changes with respect to the first edition are:
• references to subclauses in IEC 62386-101 and IEC 62386-102 updated to the new
structure of the standard;
• test sequence reworked and description of the test sequences in form of a pseudo code
instead of flow charts.
The text of this standard is based on the following documents:

• IEC 62386-101, which contains general requirements for system components;
• IEC 62386-102, which contains general requirements for the control gear.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.
INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
The setup of the standard is graphically represented in Figure 1 below.

This second edition of IEC 62386-201 is published in conjunction with the second edition of
IEC 62386-101 and the second edition of IEC 62386-102. The division of IEC 62386 into
separately published parts provides for ease of future amendments and revisions. Additional
requirements will be added as and when a need for them is recognized.
This International Standard, and the other parts that make up the IEC 62386-200 series, in
referring to any of the clauses of IEC 62386-101 or IEC 62386-102, specify the extent to
which such a clause is applicable and the order in which the tests are to be performed; the
parts also include additional requirements, as necessary. All parts that make up the
IEC 62386-200 series are self-contained and therefore do not include references to each
other.
Where the requirements of any of the clauses of IEC 62386-101 or IEC 62386-102 are
referred to in this International Standard by the sentence "The requirements of fluorescent
lamp control gear (device type 0) shall conform to IEC 62386-1xx, Clause “n”, this sentence is
to be interpreted as meaning that all requirements of the clause in question of Part 101 or
Part 102 apply, except any which are inapplicable to the specific type of lamp control gear
covered by Part 201.
All numbers used in this International Standard are decimal numbers unless otherwise noted.
Hexadecimal numbers are given in the format 0xVV, where VV is the value. Binary numbers

– 6 – IEC 62386-201:2015 RLV © IEC 2015

are given in the format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; "x" in
binary numbers means "don't care".

technical revision. The essential changes with respect to the first edition are:
• references to subclauses in IEC 62386-101 and IEC 62386-102 updated to the new
structure of the standard;
• test sequence reworked and description of the test sequences in form of a pseudo code
instead of flow charts.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
The setup of the standard is graphically represented in Figure 1.

This second edition of IEC 62386-201 is published in conjunction with the second edition of
IEC 62386-101 and the second edition of IEC 62386-102. The division of IEC 62386 into
separately published parts provides for ease of future amendments and revisions. Additional
requirements will be added as and when a need for them is recognized.
This International Standard, and the other parts that make up the IEC 62386-200 series, in
referring to any of the clauses of IEC 62386-101 or IEC 62386-102, specify the extent to
which such a clause is applicable and the order in which the tests are to be performed; the
parts also include additional requirements, as necessary.
Where the requirements of any of the clauses of IEC 62386-101 or IEC 62386-102 are
referred to in this International Standard by the sentence "The requirements of fluorescent
lamp control gear (device type 0) shall conform to IEC 62386-1xx, Clause “n”, this sentence is
to be interpreted as meaning that all requirements of the clause in question of Part 101 or
Part 102 apply, except any which are inapplicable to the specific type of lamp control gear
covered by Part 201.
All numbers used in this International Standard are decimal numbers unless otherwise noted.
Hexadecimal numbers are given in the format 0xVV, where VV is the value. Binary numbers
are given in the format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; "x" in
binary numbers means "don't care".
