IK08 vs IK10: Impact Ratings in Product Data

IK08 vs IK10: joule values, use cases, and how to capture both ratings accurately in a supplier feed or catalog without IP confusion.

Catalog teams enriching luminaires, enclosures, and industrial-distribution gear run into IK08 vs IK10 constantly. Both sit at the protective end of the IEC 62262 impact-resistance scale, but they are not interchangeable — IK08 carries 5 joules and IK10 carries 20 joules, a fourfold jump. Getting that difference wrong in a product record sends buyers to the wrong specification and breaks filter-based search for every downstream channel.

The enrichment problem is compounded by two common feed errors: IK values confused with IP codes, and IK10 over-claimed on supplier sheets that lack a test reference. Claro resolves these at scale — extracting IK ratings from PDFs and supplier feeds, normalizing them into a validated field, flagging claims that contradict the housing material or lack provenance, and writing clean values back into the PIM or ERP without manual re-keying.

At a glance

Dimension	IK08	IK10
Impact energy	5 joules	20 joules
Test mass / drop (typical)	1.7 kg from ~295 mm	5 kg from ~400 mm
Relative robustness	High	Highest on the standard scale
Common use	Indoor and sheltered fittings	Public, vandal-prone, or exposed installs
Standard	IEC 62262	IEC 62262
Data-capture risk	Confused with IP08 (not a valid IP code)	Often over-claimed in supplier sheets

IK10 is the ceiling of the published scale. A supplier sheet claiming a value above it is a flag to verify before ingestion, not a spec to trust blindly.

When to use each

IK08

IK08 fits products installed where impact is possible but not routine: an LED panel in a stairwell, a furniture-integrated power module in a hotel room, or a controls enclosure on a sheltered MRO workbench. It is a meaningful rating that buyers filter on, but it is not a vandal-resistance claim. When a manufacturer datasheet lists IK08, capture it as-is. Do not round it up to IK10 because a product looks rugged — that inflates the spec and exposes the distributor to warranty and liability risk.

IK10

IK10 belongs on products specified for abuse: street and tunnel lighting, transit-station cameras, exterior CPG vending fascias, and industrial-distribution gear mounted at floor level where forklifts and pallets are a hazard. Because IK10 carries a specification and price premium, it is the value most often over-stated in feeds. Treat any IK10 claim that lacks a test reference or contradicts the housing material as a candidate for review before it reaches the catalog.

Before and after: IK data in a supplier feed

The table below shows the messy state most enrichment projects start from and the trusted state Claro produces after extraction, validation, and write-back.

Before (raw supplier feed)	After (Claro-enriched catalog)
IK field blank or absent on 40% of enclosure SKUs	IK01-IK10 value populated on every SKU where source doc exists
IK10 claimed on plastic housing rated for lower energy	Conflicting claims flagged for human review before publish
IK value stored in the same field as IP rating	Separate normalized IK and IP fields, each validated independently
No link to the source datasheet	Provenance reference attached so any value can be audited or updated
Variant records carry inconsistent IK values	Single resolved IK value per product entity, propagated to all variants

The practical enrichment job is consistency: a normalized IK field (IK01-IK10), a separate IP field, and a provenance link back to the source datasheet so the rating can be audited rather than guessed. Claro’s AI-assisted extraction pulls these from PDFs at scale, grounds each output in the source document, and validates before write-back — so the catalog reflects what the manufacturer actually certified, not what a feed field happened to contain.

FAQ

Is IK10 better than IK08?

For impact resistance, yes — IK10 withstands 20 joules against IK08’s 5 joules, four times the energy. But better depends on the application. An indoor fitting rarely needs IK10, and specifying it adds cost. The right rating is the one that matches the installation environment, not the highest number available.

What is the joule value of IK08 and IK10?

IK08 is rated for 5 joules of impact energy and IK10 for 20 joules, under IEC 62262. The scale is non-linear, so the step from IK08 to IK10 is a large jump in protection, not a small increment.

Are IK and IP ratings the same thing?

No. IK (IEC 62262) measures resistance to mechanical impact, while IP (IEC 60529) measures protection against dust and water ingress. A product carries both independently — for example IP65 IK08. In a catalog they should live in separate, clearly labeled fields to avoid overwriting one with the other.

Is there a rating higher than IK10?

On the standard IEC 62262 scale, IK10 is the highest published level. Some manufacturers cite extended values such as IK10+ for higher energies, but these are not part of the base standard. If a supplier feed lists a value above IK10, verify the source document before trusting it.

How should I store an IK rating in product data?

Use a single normalized field constrained to valid codes IK01 through IK10, keep it separate from the IP field, and attach a provenance reference to the datasheet the value came from. This lets the rating filter correctly in search and be audited later rather than re-keyed by hand.
