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 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 60674-3-1 has been prepared by subcommittee 15C: Specifications,
of IEC technical committee 15: Insulating materials.
The text of this standard is based on the following documents:
FDIS Report on voting
15C/862/FDIS 15C/952/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

INTRODUCTION
This International Standard is one of a series which deals with plastic films for electrical
purposes.
The series consists of three parts.
– Part 1: Definitions and general requirements (IEC 60674-1).
– Part 2: Methods of test (IEC 60674-2).
– Part 3: Specifications for individual materials (IEC 60674-3).
This standard contains one of the sheets comprising part 3, as follows:
Sheet 1: Biaxially oriented (PP) polypropylene films for capacitors.

PLASTIC FILMS FOR ELECTRICAL PURPOSES –
Part 3: Specifications for individual materials –
Sheet 1: Biaxially oriented polypropylene (PP) films for capacitors
1 General
1.1 Scope
This sheet of IEC 60674-3 gives the requirements for biaxially oriented polypropylene film
having a smooth or rough surface, corona treated when required for vacuum metallization. The
films are for use as dielectric in capacitors.
1.2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this sheet of IEC 60674-3. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and parties to agreement
based on this sheet of IEC 60674-3 are encouraged to investigate the possibility of applying the
1)
most recent editions of the normative documents indicated below . Members of IEC and ISO
maintain registers of currently valid International Standards.
