Overview

EN 50582:2016 - Procedure to assess the circuit integrity of optical fibres in a cable under resistance to fire testing - is a CLC (CENELEC) European standard that specifies how to measure and report the ability of optical fibre cables to maintain signal continuity when exposed to fire. It complements the fire test methods in EN 50200 and EN 50577 by defining the point of failure, continuity checking arrangement, sample preparation, optical measurement method and test report requirements for optical-fibre cables.

Key topics and technical requirements

• Scope: Applies to optical fibre cables tested under EN 50200 (small cables, diameter ≤ 20 mm) or EN 50577 (larger fire-resistance furnace tests).
• Circuit integrity criterion: Continuity is defined by maximum allowed increase in attenuation during fire:
  • Single-mode (1550 nm): ≤ 1.0 dB per metre
  • Multimode (1300 nm): ≤ 2.0 dB per metre
• Measurement method: Optical transmittance monitoring per EN 60793-1-46, using either:
  • Individual fibre attenuation monitoring; or
  • Loop-back concatenated fibre measurements.
• Fibres tested: 2 fibres for cables with up to 6 fibres; 6 fibres for higher fibre counts, evenly distributed across the cable’s optical elements.
• Test equipment & setups:
  • EN 50200: gas burner, heat-resisting wall and shock device;
  • EN 50577: furnace (recommended minimum internal dimensions), burners, cable tray in U/S bends;
  • Optical attenuation measurement system per EN 60793-1-46.
• Sample preparation: Finished cable length (20–50 m or longer as needed) with center positioned in the flame/furnace; observe minimum bending radius as used in normal service.
• Survival time: Time from test start to point of failure (attenuation exceeds limits); recorded up to 120 minutes (extendable by agreement but not for classification).
• Test report must include: full cable description, manufacturer, lab, test wavelength, number of fibres tested, optical equipment, support/clips or trays, bending radius, temperature monitoring method, survival time, monitoring method (A or B), and standard reference.

Applications and users

• Who uses it: cable manufacturers, test laboratories, certification bodies, fire safety engineers, building services designers and specifiers, building product assessors.
• Practical uses:
  • Demonstrating circuit integrity of optical-fibre emergency/critical communications in buildings and infrastructure.
  • Supplying data for fire classification (P or PH) via EN 13501-3 using EN 50577/EN 50200 results.
  • Supporting product certification, procurement specifications and regulatory compliance for fire-resilient cabling.

3 Circuit integrity (Continuity of signal supply)
The criteria that are used for defining fire resistant optical fibre cables are deemed to demonstrate the ability
of the cable to maintain a reliable signal transmission when subjected to fire.
Circuit integrity is based upon continuity of optical signal supply.
This clause specifies characteristics that shall be used to define the continuity of signal supply / maintenance
of circuit integrity (continuity) under fire conditions for optical fibre cables.
The circuit integrity i.e. continuity of optical signal supply is deemed to be maintained if the maximum
increase in attenuation does not exceed the value given in Table 1 during the test duration.
Continuity of optical signal supply (see 4.4) can generally be performed by two methods:
(A) Monitor individual fibres for attenuation change;
(B) Loop-back measurements: this method splice
