SIST EN 60684-3-240 to 243:2004
(Main)Flexible insulating sleeving -- Part 3: Specifications for individual types of sleeving -- Sheets 240 to 243: Heat-shrinkable PTFE sleeving
- Abstract
Gives the requirements for heat-shrinkable (low and high shrink ratio) polytetrafluorethylene (PTFE) sleeving. It is normally available in expanded internal diameter sizes up to 12 mm in three wall thickness ranges as supplied in the low shrink ratio (sheets 240, 241 and 242) and up to 100 mm in one wall thickness range as supplied in the high shrink ratio (sheet 243). It is normally available in transparent milk white to light tan in colour and the minimum recovery temperature is 350 °C.
The procedures described in IEC 60216-1 for evaluation of thermal endurance are not readily applicable to PTFE: however, experience of product performance indicates that this sleeving may be suitable for inclusion in systems for operation at temperatures up to 250°C.
Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.

SIST EN 60684-3-240 to 243:2004 is the Slovenian adoption of EN 60684-3-240 to 243 for heat-shrinkable PTFE flexible insulating sleeving. It specifies the sizes, dimensions, test conditions and property requirements for low- and high-shrink-ratio PTFE sleeving used in electrical insulation applications.
What does SIST EN 60684-3-240 to 243:2004 specify?
SIST EN 60684-3-240 to 243:2004 sets requirements for heat-shrinkable polytetrafluorethylene (PTFE) sleeving in four sheets. The document is organized into Clause 1 Scope, Clause 2 Normative references, Clause 3 Designation, Clause 4 Conditions of test, Clause 5 Requirements, Clause 6 Sleeving conformance, and Annex ZA.
| Sheet | What it covers |
|---|---|
| 240 | Heat-shrinkable PTFE sleeving, low shrink ratio, thick wall |
| 241 | Heat-shrinkable PTFE sleeving, low shrink ratio, medium wall |
| 242 | Heat-shrinkable PTFE sleeving, low shrink ratio, thin wall |
| 243 | Heat-shrinkable PTFE sleeving, high shrink ratio |
The scope covers sleeving normally available in expanded internal diameter sizes up to 12 mm for the low shrink ratio sheets and up to 100 mm for the high shrink ratio sheet. It is normally available in transparent milk white to light tan, with a minimum recovery temperature of 350 °C.
The scope also notes that IEC 60216-1 thermal endurance procedures are not readily applicable to PTFE, while product experience indicates suitability for systems operating up to 250 °C. For practical use, that means the standard gives a performance specification for the material, but the user still has to judge whether the sleeving fits the actual application.
What are the key requirements of SIST EN 60684-3-240 to 243:2004?
SIST EN 60684-3-240 to 243:2004 requires compliance with the general requirements of IEC 60684-1 and the specific limits in Tables 1 to 4. In practice, the document combines identification, test preparation, dimensional limits and property checks into one specification.
Identification and test preparation
Clause 3 gives the designation format, which identifies the IEC publication, part, sheet and size in expanded/recovered bore terms. This matters when ordering or recording the sleeving, because the designation must show which sheet and size are intended.
Clause 4 says that, unless otherwise specified, the sleeving is shrunk in a forced air circulation oven for 10 minutes at 350 °C before testing. That makes the test condition consistent, so results reflect the material after a defined shrink process.
Dimensions and product range
Tables 1 and 2 set the size and mass requirements for the low shrink ratio sheets 240 to 242 and the high shrink ratio sheet 243. They also state that sleeving with a non-standard nominal internal diameter shall have a wall thickness at least as large as the next largest standard size. For buyers and quality control, this is the check that the delivered size really matches the declared product type.
Property requirements
Clause 5 requires the sleeving to meet the property limits in Table 3, including density, heat shock, longitudinal change, low-temperature bending, tensile strength, elongation at break, secant modulus and electrical breakdown voltage. These tests show whether the sleeving keeps its shape, survives handling and still provides insulation after shrinkage.
Table 3 ties several tests to IEC 60684-2 methods, and Table 4 links breakdown voltage to recovered wall thickness. The breakdown-voltage test is carried out at room temperature using one of the IEC 60684-2 methods, with voltage applied at 500 V/s. In practice, thicker sleeving has a higher minimum electrical withstand level.
Conformance
Clause 6 says conformance is normally based on size 3.0/2.0 mm for sheets 240, 241 and 242, and size 45/12 mm for sheet 243. That tells laboratories which sizes are used as the usual reference for compliance checking.
What terms does SIST EN 60684-3-240 to 243:2004 define?
- Polytetrafluorethylene (PTFE) - The fluoropolymer used for the sleeving material in this standard.
- Low shrink ratio - The sheet family for sleeving supplied in three wall thickness ranges and smaller size range.
- High shrink ratio - The sheet family for sleeving supplied in one wall thickness range and the larger size range.
- Recovered wall thickness - The wall thickness after shrinking, used to judge dimensions and breakdown voltage class.
- Concentricity - A measure of how evenly the wall surrounds the bore; it affects dimensional uniformity.
- Breakdown voltage - The electrical voltage at which the sleeving fails as an insulator.
- Volume resistivity - A measure of how strongly the material resists electrical leakage through its volume.
Who uses SIST EN 60684-3-240 to 243:2004?
SIST EN 60684-3-240 to 243:2004 is used by manufacturers, test laboratories, quality managers and purchasers of electrical insulating sleeving. It helps them specify a PTFE sleeving type, choose the right size and wall thickness, and verify that test results match the required property tables. It is relevant in electrical and electronic applications where sleeving must remain serviceable at high temperature.
What changed in SIST EN 60684-3-240 to 243:2004 from the previous edition?
SIST EN 60684-3-240 to 243:2004 is the second edition, and it cancels and replaces the first edition from 1991 as a technical revision. The European Standard also supersedes HD 523.3.240 to 243 S1:1993. CENELEC approved the IEC text without modification.
Which standards are used with SIST EN 60684-3-240 to 243:2004?
- IEC 60684-1 - Gives definitions and general requirements for flexible insulating sleeving.
- IEC 60684-2 - Gives the test methods used for the property checks in Table 3.
- IEC 60216-1 - Covers thermal endurance ageing procedures and evaluation of test results; the scope notes that these procedures are not readily applicable to PTFE.
What does the SIST EN 60684-3-240 to 243:2004 document contain?
The document contains sheet-specific specifications for four PTFE sleeving types, along with a defined designation format and a standard test-preparation condition. It includes Tables 1 and 2 for dimensions and mass, Table 3 for property requirements, and Table 4 for breakdown voltage by recovered wall thickness. It also points readers to IEC 60684-2 test methods and provides Annex ZA with the normative reference mapping to European publications.

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 60684-3-240 to 243 has been prepared by subcommittee 15C:
