IEC 61300-2-10:2021

Overview

IEC 61300-2-10:2021 - "Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-10: Tests – Crush and load resistance" specifies standardized test methods to evaluate the mechanical resistance of fibre‑optic devices when exposed to crushing and static loading. The third edition (2021) updates severities to align with IEC 61753-1:2018, and adds tests for an evenly distributed static load on the top surface of a street cabinet, a static load on a street‑cabinet door, and optional temperature‑specified testing.

Key Topics

• Scope: Tests simulate real‑world critical situations - being stepped on, run over by tyres, loads on street cabinets or open cabinet doors.
• Apparatus requirements:
  • Plate/ground: Minimum 10 mm steel plate on a non‑yielding surface with rounded edges.
  • Pad: Minimum 10 mm thick steel pad (flat circular surface); typical pad diameter 5.6 cm (~25 cm²).
  • Force generator and gauge: Smoothly apply and measure specified loads.
  • Temperature chamber: When tests are specified at non‑ambient temperatures, maintain ±2 °C.
• Test procedure (high level):
  • DUT preparation and pre‑conditioning
  • Initial visual and optical measurements (attenuation, return loss)
  • Device mounting and controlled application of load (crush or distributed)
  • Conditioning, recovery, and final examinations/measurements
• Load application details:
  • For cabinet doors, force is applied at the point producing the highest hinge moment.
  • For evenly distributed top‑surface loads, apparatus and load axes are described for consistent test reproducibility.
• Severity levels: Defined in Table 1 of the standard and updated per IEC 61753‑1:2018.

Applications

• Manufacturers of fibre‑optic connectors, closures, hardened components - to verify mechanical robustness and support product design decisions.
• Test laboratories and quality assurance teams - to perform repeatable crush and load resistance testing for compliance and reporting.
• Network operators and system integrators - to specify acceptance criteria for outdoor cabinets, street furniture and field‑deployed components.
• Procurement and certification bodies - to reference consistent, internationally recognized test methods in specifications and conformity assessment.
