IEC 60695-5-2:2026 addresses fire hazard testing from the perspective of corrosion damage. It summarises methods used to assess the corrosivity of fire effluent and comments on their relevance to electrotechnical products and their materials. The document is intended for engineers and quality professionals who must select appropriate corrosivity test methods and interpret their results.
Standard Information
Fire effluent released during a fire can corrode equipment and structures that survive the flames themselves. IEC 60695-5-2:2026 collects the test methods used to assess this corrosivity, summarises those in common use, and comments on how they relate to real fire scenarios. The document gives recommendations on the use of each method. - Designation: IEC 60695-5-2:2026
- Full title: Fire hazard testing - Part 5-2: Corrosion damage effects of fire effluent - Summary and relevance of test methods

- ICS classification: 13, 13.220, 13.220.99
- Technical committee: TC 89
Scope and Application
The standard summarises test methods used to assess the corrosivity of fire effluent. It presents a brief overview of methods in common use, whether these exist as international standards or as national and industry standards. For each method it includes observations on relevance, together with recommendations on use. A distinctive feature of this document is its evaluative character. Rather than specifying a single procedure, it compares available methods and relates them to real fire scenarios for electrotechnical products and their materials. This helps readers select a method appropriate to the product, the material, and the fire scenario of concern. According to the abstract, this edition constitutes a technical revision and includes two notable changes: a clause on the nature of the corrosivity measurement has been added, and the summary of tests for determining halogen acid in combustion gases has been updated following recent developments in a related test-method standard.
Products and Materials Covered
The document applies to electrotechnical products and the materials from which they are made. Within fire hazard testing, its subject is the corrosion damage effects of fire effluent — the gases and residues generated when materials burn. The ICS classification reinforces this positioning. Classification 13.220.99 falls under the general field of protection against fire, covering standards on fire hazard topics other than the more specific subfields. Materials whose combustion products may be corrosive, such as insulation, enclosure plastics and cable components, fall within the scope wherever they form part of electrotechnical products. The document does not restrict itself to one product family; it addresses corrosivity assessment methods relevant across electrotechnical equipment.
Testing and Compliance Considerations
As a summary and guidance document, this standard supports method selection rather than serving directly as a pass/fail specification. Laboratories typically consult it when planning corrosivity assessments, choosing among the international, national and industry methods it summarises according to product requirements and the fire scenario of interest. For procurement and quality functions, the document offers a reference point when reviewing test reports. A report on fire effluent corrosivity should identify the method applied, the material or product tested, and the measurement basis, so that results can be compared against declared requirements. Retesting is generally warranted when a material formulation changes, when a referenced test method is revised, or when a specification invokes a different corrosivity procedure. Because the document comments on relevance to real fire scenarios, engineers can also use it to justify method choices in compliance documentation and to challenge results obtained with poorly matched procedures.
Related Standards and Series Context
The designation IEC 60695-5-2:2026 follows the IEC numbering convention for multipart standards. The root number 60695 identifies the series on fire hazard testing; the part number 5-2 places this document within the group addressing corrosion damage effects of fire effluent. The suffix 2026 indicates the publication year of this edition, allowing readers to distinguish it from other editions of the same part. The structure also signals that the document sits within a broader family of fire hazard test standards, so engineers reviewing corrosivity assessment should expect companion documents covering other fire hazard effects under the same series root. Readers seeking the document itself or related parts should consult the official IEC publication channels.
Frequently Asked Questions
Which
products and materials does IEC 60695-5-2:2026 – Fire hazard testing cover?
This standard within fire hazard testing applies to electrotechnical products, their components and materials, where assessing fire hazard is relevant. Its scope covers materials used in construction of electrotechnical equipment, supporting evaluation of potential fire risks across diverse product and material types.
What
does an IEC 60695-5-2:2026 – Fire hazard testing report contain?
A typical report summarizes the tested items, applied test methods, observed results, and compliance conclusions against the standard's requirements. Reports are used by manufacturers, buyers, and regulators to demonstrate fire hazard testing compliance, support product development, and inform market access and quality documentation.
How should manufacturers approach IEC 60695-5-2:2026 – Fire hazard test submission?
Manufacturers should first confirm the product and materials fall within the standard's scope, then communicate clearly with the testing laboratory about sample requirements, applicable test conditions, and related standards in the series. Early clarification of testing and compliance considerations helps ensure a smooth submission and accurate results.
