Overview

EN 60322:2001 (CLC adoption of IEC 60322:2001) is a European standard for railway applications that defines rules for power resistors of open construction used on rolling stock. It adapts the general rules of IEC 60077‑1 specifically to resistors so manufacturers, operators and test houses have uniform requirements and avoid duplicate testing to different standards. The standard applies to braking, heating, snubber and filter resistors and other power/auxiliary circuit resistive components arranged as grids, plates, strips, ribbons or wires.

Key topics and technical requirements

• Scope and objective: Characteristics of power resistors; service conditions; required tests and test methods; required marking and product information.
• Resistor constructions covered: Open‑air resistor frames and cases, typically used in polluted environments; removable resistor elements and multi‑element assemblies.
• Performance and construction requirements: Mechanical layout, cooling (natural/forced), and insulation concepts including double insulation and multi‑stage insulation (definitions and arrangements are provided; Annex A is normative for double insulated resistors).
• Service conditions: Environmental and operational conditions specific to rolling stock (vibration, shock, pollution, humidity, temperature ranges) referenced to general rules in IEC 60077‑1.
• Tests required: Type, routine and investigatory tests covering:
  • Temperature‑rise and thermal behavior
  • Vibration and shock endurance
  • Dielectric and insulation tests
  • Hygroscopic and rain performance
  • Fault‑current and electrical measurements
• Marking and product information: Manufacturer data, resistor section identification, tolerances, and test evidence to be supplied with the product.
• Normative tables and annexes: Tolerances on resistance values, temperature‑rise limits for accessible parts, and detailed test lists and voltages.

Applications and users

• Who uses EN 60322: rolling stock manufacturers, component suppliers, electrical design engineers, maintenance teams, test laboratories and certification bodies involved with railway equipment.
• Practical uses:
  • Specifying and procuring power resistors for locomotives, EMUs, trams and other rail vehicles
  • Designing resistor assemblies to meet standardized insulation and thermal limits
  • Planning and conducting type and routine tests required for vehicle entry into service
  • Ensuring interoperability and compliance across CENELEC/CLC member countries

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60322 has been prepared by IEC technical committee 9: Electric
railway equipment.

RULES FOR POWER RESISTORS OF OPEN CONSTRUCTION
1 Scope and object
This International Standard gives the rules for all power resistors (for example, braking,
heating, snubber and filter) used in the power and auxiliary circuits on board rolling stock
irrespective of the circuit and the type of vehicle where they are used.
These resistors are generally of open construction and are used in polluted areas. The
construction consists of resistor elements of grids, plates, strips, ribbons or wires.
NOTE Certain of these rules may, after agreement between user and manufacturer, be used for electrical
equipment installed on other vehicles such as mine locomotives, trolley buses, etc.
This standard states
– the characteristics of the resistors;
– the service conditions with which the power resistors have to comply;
– the tests intended for confirming that these conditions have been met and the methods to
be adopted for these tests;
– the information to be marked on, or given with, the resistors.
This standard does not give requirements relating to general service conditions and general
rules which are given in IEC 60077-1.
The object of this standard is to adapt the general rules given in IEC 60077-1 to power
resistors for rolling stock in order to obtain uniformity of requirements and tests throughout the
corresponding range of components and to avoid the need for testing to two different
standards.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.

3 Definitions
For the purpose of this International Standard, the definitions of IEC 60050(811) and the
following definitions apply.
3.1
resistor element
resistive conductor forming part of a resistor case or frame, usually in the form of grids, plates,
strips, ribbons or wires and which may have intermediate tappings
[IEV 811-27-11]
NOTE A resistor element is usually a removable assembly.
3.2
resistor
general term used in this standard to designate any of the following forms of electrical
resistance
3.2.1
resistor case
resistor frame
set of resistor elements assembled into a single structure
[IEV 811-27-12]
NOTE 1 Resistor case is used for resistors having one or more resistor elements installed in an enclosure
intended to form part of a forced air cooling duct.
NOTE 2 Resistor frame is used for resistors having one or more resistor elements installed on a common frame
for natural cooling in open air.
3.2.2
