Part 2: Methods of test
FOREWORD
1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National
Committees in that sense.
3) In order to promote international unification, the IEC expresses the wish that all National Committees
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
This part of International Standard IEC 1067 has been prepared by Sub-Committee 15C:
Specifications, of IEC Technical Committee No. 15: Insulating materials.
The text of this standard is based on the following documents:
Six Months' Rule Report on Voting
15C(CO)236 15C(CO)260
Full information on the voting for the approval of this part can be found in the Voting
Repo rt indicated in the above table.

INTRODUCTION
This International Standard is one of a series which deals with glass and glass polyester
fibre woven tapes.
The standard consists of three parts:
- Part 1: Definitions, classification and general requirements (IEC 1067-1).
- Pa
rt 2: Methods of test (IEC 1067-2).
- Part 3: Specifications for individual materials (IEC 1067-3).
This part specifies the methods of test.

SPECIFICATION FOR GLASS AND GLASS POLYESTER
FIBRE WOVEN TAPES
Part 2: Methods of test
1 General
1.1
Scope
This International Standard specifies requirements for loomstate, continuous filament
tapes woven on conventional or shuttleless looms from either glass fibres or a combina-
tion of glass and polyester fibres.
This part of IEC 1067 gives methods of test to demonstrate compliance with the general
requirements of Part 1 and the specific requirements of Part 3.
1.2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this International Standard. At the time of publication of
this normative document, the editions indicated were valid. All normative documents are
subject to revision, and 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. Members of IEC and ISO maintain registers of
currently valid International Standards.
IEC 212: 1971, Standard conditions for use prior to and during the testing of solid elec-
trical insulating materials.
ISO 5081: 1977, Textiles - Woven fabrics - Determination of breaking strength and
elongation (Strip method).
ISO 5084: 1977, Textiles - Determination of thickness of woven and knitted fabrics (other
than textile floor coverings).
2 Tests
2.1
Determination of number of warp ends
The ends shall be counted across the full width of the tape under ordinary room conditions
and divided by the nominal width to obtain the ends per 10 mm of nominal width.
2.2 Determination of number of picks
The picks shall be counted over not less than a 20 mm length of tape under ordinary room
conditions and the average value shall be calculated from not less than three individual
tests made at three different places along the tape.
NOTE - For types 2 and 3, two threads equal one pick (see the definition of "pick" in Part 1 of IEC 1067).

2.3 Determination of thickness
modified as
The thickness shall be generally determined by the method given in ISO 5084,
below:
2.3.1 Test pieces
Take five rolls of tape selected at random.
2.3.2 Conditioning
45 % to 75 %
Condition the rolls in an atmosphere of relative humidity within the range
as in IEC 212 and then measure the
and with a temperature between 15 °C and 35 °C
thickness under these conditions.
2.3.3 Test apparatus
Use test apparatus complying with that described in ISO 5084.
2.3.4 Test procedure
Clean the surfaces of the reference plate and the presser-foot. Adjust the instrument to
kPa. In case of dispute, a deadweight tester shall be
provide a pressure of 100 kPa to 200
used and the pressure shall be 100 kPa.
Separate the parallel plates and place an uncreased part of the test piece without tension
in contact with the reference plate.
Gently reduce the distance between the reference plate and the presser-foot until contact
is made with the tape and note the reading of the gauge immediately after the easily
visible movement of the pointer has ceased.
On each of the five selected rolls, make four measurements at random, one at each of the
selvedges and two between the selvedges
