Overview

EN 61300-2-26:2007 (identical to IEC 61300-2-26:2006) specifies a standardized salt mist (salt spray) test for fibre optic interconnecting devices and passive components. The procedure evaluates the corrosion resistance of metals used in connector and component construction and checks whether dissimilar metals have been suitably finished to prevent galvanic or surface corrosion. The test is carried out in accordance with IEC 60068-2-11 (Test Ka) in a controlled salt-mist environment at a chamber temperature of 35 °C.

Key topics and technical requirements

• Scope: Corrosion-resistance assessment for metals and metal finishes in fibre optic interconnects and passive components.
• Test basis: Conducted in accordance with IEC 60068-2-11 (Test Ka).
• Chamber conditions:
  • Chamber materials must not influence corrosive effects and must provide homogeneous, turbulence-free conditions.
  • No direct spray onto specimens; dripping from chamber surfaces must not fall on specimens.
  • Proper venting to avoid pressure build-up and ensure uniform salt mist distribution.
• Salt solution:
  • Sodium chloride (NaCl) with low impurities (≤0.1% sodium iodide; ≤0.3% total impurities).
  • Concentration: (5 ± 1) % by weight (5 parts salt in 95 parts distilled/deionized water).
  • pH: 6.5 to 7.2 at (35 ± 2) °C; pH must be measured per batch and maintained during conditioning (HCl or NaOH may be used to adjust pH while keeping NaCl concentration within limits).
  • Sprayed solution must not be reused.
• Apparatus:
  • Atomizers produce a fine, dense mist and must be made from non-reactive materials.
  • Compressed air to atomizer must be essentially free from oil and dust; recommended relative humidity ≥85% at nozzle to reduce nozzle clogging.
  • Use distilled, demineralized or deionized water for humidity control.
  • Provision for heating and humidifying compressed air and chamber temperature control.
• Measurements & procedure:
  • Preconditioning, initial measurements, controlled exposure (conditioning), recovery and final measurements are required (see IEC 61300-1 and parts 3-1/3-3 for guidance on visual and performance checks).

Practical applications

• Verifies long-term reliability of connectors, adapters, receptacles and passive fibre components in marine, coastal, industrial or outdoor environments where salt contamination or marine aerosols are a concern.
• Used to qualify material selection, surface treatments, plating and assembly processes against corrosion risks.
• Supports product design validation, supplier qualification, quality assurance, and compliance for telecommunications, datacom and industrial fibre-optic products.

Who uses this standard

• Fibre-optic component manufacturers and design engineers
• Environmental and reliability test laboratories
• Quality assurance, procurement and compliance teams
• OEMs integrating fibre-optic interconnects into equipment for harsh environments

• IEC 60068-2-11 (Environmental testing - Test Ka: Salt mist)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC Nati
