Overview
EN 50655-2:2017 - published by CLC - is the European standard for material characterization (fingerprinting) of heat shrinkable components used in cable accessories for low and medium voltage systems up to 20,8/36 (42) kV. The standard defines the purpose, sampling, preparation, test methods and reporting requirements for establishing and subsequently confirming the properties of heat‑shrink tubing, wraparound sleeves, molded parts and similar components used for electrical insulation and/or mechanical protection in cable accessories.
Key topics and technical requirements
- Scope and purpose: Fingerprinting is a standalone verification method (but may be combined with accessory type tests) to record material signatures for later comparison and quality control.
- Sampling and conditioning: Samples are taken from supplier‑stored material or from the same batch used for accessory type tests as agreed between supplier and user. Components must be fully recovered (heated) and conditioned per supplier instructions before testing.
- Mandatory fingerprinting tests (see Table 1 in the standard):
- Dimensions after full recovery (EN 60684-2): inner diameter and wall thickness with allowed deviations (typically ±10 % for inner diameter; wall thickness ±10–15 % depending on thickness).
- Density (EN ISO 1183 series): measured without sealant; multi‑layer components require measurement of each layer (±5 % deviation).
- Differential Scanning Calorimetry (DSC) (EN ISO 11357-3): characteristic transition temperatures (melting/crystallization peaks) recorded; deviations ±5 K.
- Thermogravimetric Analysis (TGA) (EN ISO 11358-1): polymer, carbon black, filler and sealant content and decomposition temperatures with specified deviation limits (typically ±10 % for composition, ±15 K for temperature).
- Test report requirements: part identification, supplier, batch/date, full test methods and results, preparation/conditioning details, and copies of TDS and MSDS.
Applications and users
- Who uses it: cable accessory manufacturers, material suppliers, independent test laboratories, utilities, procurement teams and specification engineers.
- Practical uses:
- Establishing baseline material “fingerprints” for incoming quality control and supplier qualification.
- Confirming material identity after storage, after supplier changes, or during failure investigations.
- Supporting conformity assessment when used alongside accessory type tests (EN 50393, HD 629.1, HD 629.2).
- Ensuring compatibility of multi‑layer or sealant‑containing components in low/medium voltage joints and terminations.
Related standards
- EN 50655-1 (resinous compounds) and EN 50655-3 (cold shrinkable components)
- EN 50393 (accessory test methods), HD 629.1 / HD 629.2 (accessories for MV cables)
- EN 60684-2, EN ISO 1183, EN ISO 11357-3, EN ISO 11358-1
