Direct answer
Salt-mist corrosion evidence must match the actual metals, finishes and assembly revision. IP68 or a metallic appearance does not establish corrosion resistance. Review specimen identity, method, exposure and post-test criteria; this guide does not convert test hours into years of coastal service.
Definition: enclosure protection and corrosion are separate
The public scope of IEC 61300-2-26:2023 addresses corrosion resistance of metals used in optical interconnecting devices and passive components, including finishing of dissimilar metals. IEC salt-mist scope
The IP Code classifies enclosure protection; it does not replace a salt-mist report. IEC 60529 This review does not prescribe one severity for every coastal installation.
Applications and report checklist
Define environmental requirements for exposed housings, locks, fasteners and other metal parts in addition to optical loss. The table lists suggested procurement fields, not the complete IEC procedure.
| Field | Find in the evidence | Inadequate substitute |
|---|---|---|
| Specimen revision | Housing, fastener and assembly IDs | “Same product family” |
| Materials/finishes | Revisions and dissimilar-metal contacts | Metallic appearance |
| Test state | Mated, capped or prescribed configuration | An unexplained photograph |
| Exposure/recovery | Method, conditions, duration and recovery | One hour count |
| Post-test function | Agreed visual, operational and optical checks | No water ingress alone |
Matching base metals does not make reports interchangeable. Changes in finishes, fasteners or contact geometry require an applicability review.
Using evidence in procurement
Identify the installed configuration, exposed metals and relevant contact locations. Agree the specimen state and applicable test before requesting a report. Before/after photographs alone do not establish the procedure or functional verdict.
Record appearance separately from agreed operation and optical results. If sealing verification is required, specify its applicable method rather than assuming salt-mist acceptance covers it. A housing-only report should clearly identify the untested complete assembly.
Do not convert duration into lifetime
A laboratory exposure is not a field-service history. This guide supplies no universal hours-to-years conversion and does not infer a lifetime for every production unit from one specimen. Specify environment, configuration, acceptance and change-control responsibilities instead.
No ARRANEX salt-mist certification or verified coastal lifetime is claimed.
Procurement FAQ
- Does IP68 cover every coastal installation? Also review corrosion, installation and maintenance.
- Can one report cover the same base metal? Check finishes and assembly revisions.
- Is a duration alone enough? Require method, state, conditions and verdict.
- Does salt-mist acceptance prove optical performance? Review the specified post-test optical checks.
- How many hours equal years? No universal conversion is provided; use project evidence.
