Overview
EN 61068-2:1997 (Specification for polyester fibre woven tapes - Part 2: Methods of test) specifies laboratory test procedures used to demonstrate compliance with the general requirements of Part 1 and the material-specific requirements of Part 3. Published by CLC and aligned with IEC 61068-2:1991, this standard defines repeatable methods for measuring physical and mechanical properties of continuous-filament polyester woven tapes used in electrical insulation and related applications.
Key topics and technical requirements
The standard sets out detailed test methods and conditions, including:
- General scope - Applies to tapes woven on shuttleless looms from continuous-filament polyester fibres; Part 2 provides the test methods to verify Parts 1 and 3.
- Normative references - Incorporates relevant international test standards such as ISO 5081 (breaking strength/elongation) and ISO 5084 (thickness).
- Count and structure measurements
- Determination of number of warp ends (ends per 10 mm).
- Determination of picks (weft threads) using defined sample lengths and averaging.
- Dimensional tests
- Thickness measured to ISO 5084 with specified conditioning (relative humidity 45–75%, temperature 15–35 °C) and presser-foot pressure (nominally 100 kPa).
- Width measured on un-tensioned tape with steel rule; multiple measurements averaged.
- Thermal shrinkage
- Oven test at 155 ± 5 °C for 60 ± 10 minutes, cooling for 1 hour at 15–35 °C; shrinkage reported as percentage and in mm.
- Mechanical strength
- Tensile strength determined using ISO 5081 methodology (modified): five specimens, unstretched gauge length 200 mm, test temperature 15–35 °C; results expressed in N/mm width.
- Heat-activated force (shrink-force)
- Method to determine maximum force developed when tape is heated to approximately 150–155 °C: 100 mm jaw spacing, nominal preload ~5% of estimated breaking load, temperature ramp in 10–15 minutes; central value of three measurements reported.
Applications and users
This methods standard is practical for:
- Manufacturers of polyester filament woven tapes for quality control and product specification verification.
- Independent test laboratories performing acceptance testing, supplier audits, and certification testing.
- Procurement and specification writers who need standardized test results for contracts and technical datasheets.
- Design engineers in electrical insulation, wire and cable harnessing, and industrial strapping who require validated mechanical and thermal performance data.

SPECIFICATION FOR POLYESTER FIBRE WOVEN TAPES
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 la tter.
This part of International Standard IEC 1068 has been prepared by Sub-Committee 15C:
Specifications, of IEC Technical Committee No. 15: Insulating materials.
The text of this part is based on the following documents:
