SIST EN 60811-503:2012
Electric and optical fibre cables - Test methods for non-metallic materials - Part 503: Mechanical tests - Shrinkage test for sheaths
- Abstract
IEC 60811-503:2012 gives the test method for the shrinkage for sheaths. IEC 60811-503:2012 cancels and replaces Clause 11 of IEC 60811-1-3:1993, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012. This publication is to be read in conjunction with IEC 60811-100:2012.

SIST EN 60811-503:2012 is the Slovenian adoption of EN 60811-503:2012, published by SIST and aligned with IEC 60811-503:2012. It specifies a shrinkage test for cable sheaths used on electric and optical fibre cables. Engineers, quality teams, and test laboratories use it when they need a common method to check how a sheath behaves after heating.
What does SIST EN 60811-503:2012 specify?
SIST EN 60811-503:2012 gives one mechanical test method: the shrinkage test for sheaths. The standard is part of the IEC 60811 series for test methods for non-metallic materials, so it fits into broader cable material testing rather than standing alone.
The document is organized into a short, procedure-based structure.
| Clause or annex | What it covers |
|---|---|
| Clause 1 | Scope |
| Clause 2 | Normative references |
| Clause 3 | Terms and definitions |
| Clause 4 | Test method, including equipment, sampling, preparation, procedure, and expression of results |
| Clause 5 | Test report |
| Annex ZA | Normative references to international publications with corresponding European publications |
| Bibliography | Reference to IEC 60811-1-3:1993, marked withdrawn |
The scope is narrow and practical: it tells users how to measure shrinkage of sheaths, and it ties the method to the general rules in IEC 60811-100.
What are the key requirements of SIST EN 60811-503:2012?
SIST EN 60811-503:2012 is a laboratory test method, so the main requirements are about specimen selection, conditioning, heating, measurement, and reporting. In practice, the standard tells you how to prepare the sample and how to judge the change in length after repeated heat exposure.
Sampling and test pieces
The cable to be tested is stored for at least 24 h at room temperature before the test. One test piece of complete cable, 500 ± 5 mm long, is taken at least 2 m away from the cable end. This matters because the result should represent the cable sheath, not an area affected by cutting or handling at the end.
Measuring the initial and final length
The initial sheath length is measured immediately after cutting as the mean of two longitudinal measurements between diametrically opposite marks. If the sample is bent, the measurements are taken on the inside and outside of the bend. This gives a practical way to track how much the sheath shortens after heat exposure.
Test equipment and heating cycle
The test uses an electrically heated air oven that can maintain the required temperature, plus a measuring tape with 1 mm scale division. The test piece is supported horizontally in the oven, heated at the temperature specified in the cable standard for the specified time, removed, and allowed to cool in air to room temperature. That cycle is repeated five times, so the result reflects repeated thermal exposure rather than a single heat event.
Result and reporting
SIST EN 60811-503:2012 expresses shrinkage as a percentage based on the change between the initial and final marked distances. The test report follows IEC 60811-100. For users, this means the method defines how to measure and calculate the result, while the general reporting format comes from the companion part.
What terms does SIST EN 60811-503:2012 define?
SIST EN 60811-503:2012 sends users to IEC 60811-100 for terms and definitions, and the method uses a small set of technical terms.
- Sheath - the cable covering being checked for shrinkage after heating.
- Test piece - one complete cable specimen cut to the specified length for the test.
- Air oven - the electrically heated chamber used to hold the specimen at test temperature.
- Thermal cycle - one heat exposure in the oven followed by cooling in air to room temperature.
- Percentage shrinkage - the result reported as the length change after heating and cooling, compared with the initial length.
- IEC 60811-100 - the general part that provides the shared terms, general test rules, and report format.
Who uses SIST EN 60811-503:2012?
SIST EN 60811-503:2012 is used by cable manufacturers, test laboratories, and quality control teams that assess non-metallic cable materials. It is also relevant to specifiers and buyers who reference cable construction or cable material standards and need a repeatable sheath shrinkage test.
The IEC 60811 series is described as a basic set of methods used mainly for energy cables, and also widely used for optical fibre cables, communication and control cables, and cables for ships and offshore applications. In practice, that means the method helps compare sheath behavior across different cable families.
What changed in SIST EN 60811-503:2012 from the previous edition?
SIST EN 60811-503:2012 replaces Clause 11 of IEC 60811-1-3:1993, and the European foreword says it supersedes Clause 11 of EN 60811-1-3:1995 plus A1:2001, partially. The standard also states that there are no specific technical changes compared with the previous edition.
Which standards are used with SIST EN 60811-503:2012?
SIST EN 60811-503:2012 is used together with IEC 60811-100:2012, and the European text identifies EN 60811-100:2012 as the corresponding publication. Part 100 supplies the general framework, including terms and definitions and the report format, so Part 503 can focus on the shrinkage test itself.
What does the SIST EN 60811-503:2012 document contain?
SIST EN 60811-503:2012 contains a single test method with supporting procedural detail. It sets out the equipment, sample conditioning, specimen dimensions, marking and length measurement approach, oven test cycle, and the calculation method for shrinkage. The document also includes a test-report requirement, a normative reference list in Annex ZA, and a bibliography entry for the withdrawn predecessor.
