Overview - IEC TR 62362:2010 (Selection of optical fibre cable specifications relative to MICE)
IEC TR 62362:2010 is a technical report from the IEC that provides guidance for selecting optical fibre cable specifications relative to Mechanical, Ingress, Climatic and Electromagnetic (MICE) characteristics as classified in ISO/IEC 24702. It is a guidance document (not a product standard) that maps typical MICE severity levels (M1, M2, M3) - from office premises to light industrial and worst‑case industrial environments - to relevant cable attributes and test options.
Key topics and technical requirements
The report discusses MICE attributes and the practical test options in IEC cable standards (IEC 60794 series) and fibre standards (IEC 60793 series). Key technical topics include:
- MICE severity levels: three severity levels (M1I1C1E1 → M3I3C3E3) tied to installation environments (e.g., ISO/IEC 11801 office premises vs. industrial sites).
- Mechanical: shock/bump (not a primary concern), vibration (generally robust), tensile force (rated tensile for outdoor cables; fibre strain limits tied to proof test), crush (plate‑to‑plate test; typical indoor 500 N; unarmoured outdoor ~1 500–3 000 N; armoured 2 200–10 000 N), impact (indoor ~1 J with 12.5 mm radius; outdoor options include 10 J/300 mm or 3 J/10 mm), bending/flexing/torsion (bending diameters typically ~20× cable diameter; torsion tests vary with length, load and cycles).
- Ingress: cable construction (slotted core, loose tube, tight‑buffered; filled vs unfilled) affects particulate and water ingress. Particulate ingress is generally not an issue for optical fibre cables. Water immersion tests use a pressure equivalent to 1 m water applied at/near one end of a short cable sample (see full text for exact sample length and procedure).
- Climatic & Electromagnetic: ambient temperature ranges, humidity, solar radiation and gaseous/liquid pollution resistance are covered conceptually, with tables and options for different severities.
Note: IEC TR 62362 provides guidance and references; for normative test procedures and exact limits consult the cited standards (IEC 60794‑1‑2, IEC 60794‑2, IEC 60794‑3, IEC 60793, ISO/IEC 24702, ISO/IEC 11801).
Practical applications - who uses this standard
- Cable specifiers and procurement teams selecting cables for offices, industrial premises, outdoor plant or mixed environments.
- System integrators and network designers aligning cable choices with environmental risks (MICE).
- Test laboratories and manufacturers referencing applicable tests and performance classes from IEC 60794 series.
- Facilities and industrial engineers planning resilient premises cabling under climatic, mechanical or contamination stresses.
