01 / GUIDE

ISO 11898-2:2026

Defines high-speed CAN physical medium attachment requirements. It does not make application messages interchangeable.

Confirm transceiver compatibility, bus settings, wiring and the actual message definition.

No. Match the supported bus type, bitrate, message protocol, identifiers and data interpretation. ISO 11898-2 covers the high-speed CAN physical interface, not a universal application message format. A dashboard, ECU or lambda module still needs compatible protocol support or an explicitly supported configuration.

02 / GUIDE

ISO 16750-2:2023

Addresses electrical loads on road-vehicle electrical and electronic equipment. EMC is outside its scope.

Confirm supply conditions and product-specific test evidence; this part does not establish EMC compliance.

No. ISO 16750-2:2023 addresses electrical loads for road-vehicle electrical and electronic equipment; its scope excludes EMC and motorcycle or moped environmental testing. Ask for the exact test standard, edition, conditions, acceptance limits and report for the offered product. A standards reference is not a certification or evidence that testing was performed.

03 / GUIDE

ISO 20653:2023

Defines IP protection and related tests for road-vehicle electrical equipment enclosures.

Verify the complete assembly and installation condition. A sealed connector alone does not establish the ECU rating.

No. ISO 20653 defines IP protection and enclosure tests for road-vehicle electrical equipment. Any claimed rating must apply to the exact enclosure and specified installation conditions. Request the product-specific rating and evidence; connector sealing alone does not establish a complete assembly rating or suitability for immersion or pressure washing.

04 / GUIDE

IPC/WHMA-A-620

An industry reference for cable and wire harness assembly workmanship and acceptance.

Agree the revision, product class, drawings and inspection records for the particular order.

IPC/WHMA-A-620 provides requirements and acceptance criteria for cable and wire harness assemblies. If needed, specify the agreed revision, product class, drawings and required inspection records in the purchase specification. Citing the standard does not establish that a supplied harness or its assembler is certified.

05 / GUIDE

Incoterms® 2020

ICC rules allocating delivery obligations, costs and risk when incorporated into the sales agreement.

Specify the chosen rule, named place and edition; taxes, payment and warranty still need separate agreement.

Do not assume either. Agree customs responsibilities, duties, taxes, clearance costs and insurance in writing. If using Incoterms® 2020, state the chosen rule and named place or port in the contract. These rules allocate delivery tasks, costs and risks; they do not replace the full sales, payment or warranty terms.
