Overview
EN 50363-10-2:2005 is the CENELEC European standard that defines the test requirements for thermoplastic polyurethane (TMPU) sheathing compounds used on low voltage energy cables. It specifies the physical-property criteria and referenced test methods for the harmonised TMPU formulation listed in Table 1 (type TMPU 90, maximum operating temperature 90 °C). EN 50363-10-2 is intended to be read in conjunction with EN 50363-0 and uses test procedures from the EN 60811 series and EN 50396.
Keywords: EN 50363-10-2:2005, thermoplastic polyurethane, TMPU, sheathing compound, low voltage energy cables, test requirements, EN 60811, EN 50396.
Key topics and technical requirements
The standard focuses on measurable physical properties and pass/fail criteria for TMPU sheathing compounds. Key test areas include:
- Mechanical properties (tensile and elongation)
- Minimum median tensile strength before ageing: 25 N/mm²
- Minimum median elongation at break before ageing: 300%
- Limits on variation after thermal ageing, oil immersion and hydrolysis (typically ±30% to ±40% depending on test).
- Thermal ageing
- Ageing in air oven at 110 °C for 7 × 24 h with defined variation limits for tensile and elongation.
- Resistance to hydrolysis (water immersion)
- Immersion at 80 °C for 7 × 24 h with retention requirements for elongation and tensile properties.
- Oil resistance
- Immersion in mineral oil at 100 °C for 7 × 24 h with allowable variation limits.
- Heat shock
- Exposure at 150 °C for 1 hour - no cracks permitted.
- Pressure (indentation) test at high temperature
- Maximum median indentation depth 50% under specified load and temperature.
- Low temperature performance
- Bending and elongation tests at −50 °C (no cracks; minimum elongation without break 30%).
- Tear strength
- Mean minimum value 40 N/mm.
- Resistance against saponification
- Maximum mean value 200 mg KOH/g (EN 50396 method).
All tests reference the specific clauses of EN 60811 and EN 50396 for method details.
Applications and who uses this standard
EN 50363-10-2 is used by:
- Cable manufacturers specifying or qualifying TMPU sheaths for low voltage power cables
- Material suppliers and compound formulators validating TMPU performance
- Independent testing laboratories performing standardized cable-material tests
- Specifiers, procurement teams, and certification bodies requiring harmonised physical-property evidence for outdoor, low-temperature flexible sheaths
Typical applications include outdoor low-temperature flexible sheathed cables where thermoplastic polyurethane is selected for abrasion resistance, flexibility and weathering performance.
Related standards
- EN 50363-0 (general requirements for insulating/sheathing materials)
- EN 60811 series (test methods for non-metallic materials of cables)
- EN 50396 (specific test procedures referenced by EN 50363-10-2)
EN 50363-10-2:2005 provides the harmonised test criteria that help ensure consistent TMPU sheathing performance across the cable industry.
