Overview

EN 60811-511:2012/A1:2017 (IEC 60811-511:2012/A1:2017) specifies a laboratory procedure for measuring the melt flow index (MFI) of polyethylene and polypropylene compounds used in electric and optical fibre cables. The amendment extends the original part to explicitly include polypropylene compounds and updates test expressions and procedural details. The MFI (also referenced as melt mass-flow rate, MFR, in ISO 1133) quantifies the mass of material extruded through a calibrated die over a fixed time under a defined load and temperature.

Key Topics and Technical Requirements

• Scope: Measurement of MFI for polyethylene and polypropylene compounds used in cable insulation and sheaths. MFI is not applicable to flame-retarding polyethylene.
• Definition: MFI = quantity of material extruded in 1.5 min or 10 min at a specified temperature through a specified die under a set load.
• Test temperatures:
  • Polyethylene: (190 ± 0.5) °C
  • Polypropylene: (230 ± 0.5) °C
• Apparatus: Cylinder/piston extrusion apparatus with a heater capable of maintaining the test temperature (automatic temperature control recommended). Temperature measuring devices should be calibrated against a mercury-in-glass thermometer immersed in the compound.
• Samples: Test on granules or a section of insulation/sheath from cable; solid samples cut to pieces not exceeding 3 mm in any direction.
• Procedure essentials:
  • Clean apparatus before tests.
  • Preheat cylinder and piston at the test temperature for 15 minutes.
  • After introducing the sample, wait 4 minutes for temperature stabilization, then apply the load to extrude the compound.
• Loads and result notation: Results are reported in the standardized format (e.g., MFI.T.20.A, MFI.T.50.C), where T = test temperature (°C) and numbers like 20 or 50 indicate the approximate load in newtons (20 N or 50 N depending on method).

Applications and Users

• Who uses it: cable manufacturers, polymer compound suppliers, independent testing laboratories, R&D teams, and quality assurance engineers in the cable and polymer industries.
• Why it’s used:
  • Routine quality control and batch acceptance of polyethylene and polypropylene compounds.
  • Material selection and verification for extrusion processing (insulation and sheath).
  • Troubleshooting extrusion processability and ensuring consistent rheological properties across production lots.
  • Comparative testing aligned with international test methods (ISO/IEC) for regulatory and procurement specifications.

Related Standards

• IEC 60811-100 - general principles for test methods for non-metallic cable materials (this part is to be used in conjunction with EN 60811-511).
• ISO 1133 - melt mass-flow rate (MFR) method (equivalent procedure referenced).

Keywords: EN 60811-511, IEC 60811-511, melt flow index, MFI, polyethylene, polypropylene compounds, cable materials testing, MFR, ISO 1133, extrusion testing.
