IEC/EN 62262 impact-resistance evidence for electrical cabinets, control panels, junction boxes, outdoor housings, telecoms enclosures and infrastructure equipment.
IK impact protection testing assesses whether an electrical or electronic enclosure can withstand defined external mechanical impacts under an agreed IK rating, product standard or customer specification.
Send your target IK rating, standard, drawing, enclosure dimensions, mounting arrangement, sample details and acceptance criteria for engineering review before quotation.
Resonate supports enclosure IK testing for engineers, product developers, compliance teams, quality teams, manufacturers and specifiers who need impact-resistance evidence before qualification, validation, supplier approval, customer acceptance, durability assessment or product release.
IK testing is a controlled assessment of an enclosure’s resistance to external mechanical impacts. It generates evidence against an agreed IK rating, customer requirement or product standard.
The route depends on target IK rating, enclosure design, mounting condition, exposed faces, impact locations and acceptance criteria.
Ingress Protection testing
Sand and Dust testing
Vibration Testing
Corrosion and salt spray testing
Environmental Testing
IK testing is relevant when impact resistance must be shown before a product, enclosure or installation is accepted. Common triggers include customer specifications, product standards, supplier approval, installation approval, design validation or exposed public and industrial environments.
IK testing should be planned against the agreed product standard, customer requirement and acceptance criteria. IEC/EN 62262 is the primary IK classification standard, while IEC 60068-2-75 describes hammer impact methods that may be relevant to the route.
Related standards can also affect the evidence required. IEC 60529 is the IP ingress protection reference, IEC 62208 is relevant to empty enclosures for low-voltage switchgear and controlgear assemblies, and IEC 61587-1 can be relevant for cabinets, racks, subracks and chassis structures.
Early review helps confirm the target IK rating, sample setup, exposed faces, impact locations, mounting condition and post-test inspection requirements before testing is committed.

| Standard / Guidance | Primary Focus | Typical Relevance to Testing |
|---|---|---|
| IEC/EN 62262 | IK impact protection rating classification | Defines the IK code and impact energy levels used to classify enclosure robustness. |
| IEC 60068-2-75 | Impact test procedures and equipment | Provides recognised hammer test methods used to demonstrate impact resistance. |
| IEC 60529 | Ingress protection (IP) classifications | Often specified alongside IK ratings where both environmental sealing and impact resistance are required. |
| Customer specifications | Project-specific validation requirements | Defines the exact test conditions, pass/fail criteria and reporting expectations for the product. |
Testing reviewed against IEC/EN 62262 is intended to assess how an enclosure resists defined external mechanical impacts. Typical objectives include confirming the target IK rating, exposed faces, impact locations, mounting condition, sample configuration and post-test acceptance criteria.
Test planning is normally based on the exact enclosure design and customer requirement. Drawings, dimensions, material details, mass, mounting arrangement, energised status, linked IP requirements and reporting expectations should be reviewed before testing begins.
Resonate Testing supports product development, validation and compliance programmes through engineer-led IK impact testing. Services include test planning, controlled mechanical impact testing, inspection, reporting and evidence generation against IEC/EN 62262, IEC 60068-2-75 and customer-specific requirements. Testing can be delivered as a standalone service or combined with environmental, ingress protection, vibration and shock testing to provide a more complete product qualification programme.
IK testing depends on the enclosure design and how it will be installed, so the requirement should be reviewed before quotation.
| Specification | Capability |
|---|---|
| Primary standard | IEC/EN 62262 IK classification review |
| Impact method reference | IEC 60068-2-75 hammer-method requirements where applicable |
| Target rating | Agreed IK rating or customer-defined impact requirement |
| Sample details | Enclosure dimensions, mass, material details, photos and drawings |
| Mounting condition | Mounted as used where required, with installation arrangement reviewed before quotation |
| Impact locations | Exposed faces, vulnerable features and customer-specified locations |
| Sample quantity | Quantity confirmed against the agreed route, acceptance criteria and inspection needs |
| Acceptance criteria | Functional, safety, access, deformation, ingress or post-test inspection requirements agreed in advance |
| Linked IP requirements | Identified separately, because IK impact performance does not prove IP ingress performance |
| Report outputs | Method, setup, impact sequence, observations, result, limitations and deviations |
| Test planning support | Requirement review, enclosure setup review, mounting review, impact location review and reporting alignment |
