ISO 8820-9:2014 specifies fuse-links with shortened tabs (Type K) for use in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements, and dimensions. ISO 8820-9:2014 is applicable to fuse-links with a rated voltage of 58 V, a current rating of ≤ 30 A, and a breaking capacity of 1 000 A intended for use in road vehicles. ISO 8820-9:2014 is intended to be used in conjunction with ISO 8820‑1 and ISO 8820‑2.

Overview

ISO 8820-9:2014 - Road vehicles - Fuse-links - Part 9 specifies fuse-links with shortened tabs (Type K) for use in road vehicles. The standard defines rated current classes, test procedures, performance requirements and dimensional specifications for Type K fuse-links intended for low-voltage automotive applications (rated voltage 58 V, current ≤ 30 A, breaking capacity 1 000 A). ISO 8820-9:2014 is intended to be used together with ISO 8820‑1 (definitions & general tests) and ISO 8820‑2 (user’s guide).

Key topics and technical requirements

Scope and ratings

Applicable to Type K fuse-links: rated voltage 58 V, current rating up to 30 A, breaking capacity 1 000 A.

Performance and test sequences

Prescribes complete test sequences (clause numbering aligned with ISO 8820‑1) including dimensional checks, marking, voltage-drop, transient current cycling, operating time, current steps and breaking-capacity tests.
Requires visible evidence of a blown fuse element after operation.

Electrical limits

Voltage drop and connection resistance are measured across defined points; maximum voltage-drop limits depend on fuse rating (typically in the 120–250 mV range across ratings).

Time-current characteristics

Operating time and current step requirements (e.g., 1.1×, 1.35×, 1.6× rated current tests) with specified minima and maxima for fuse clearing times.

Breaking capacity

Verified at 1 000 A using specified cable sizes and a test dummy geometry defined in the standard.

Mechanical and environmental

Terminal strength tests (defined forces and maximum deformation), climatic, chemical and mechanical load conditions.

Marking and colour coding

Colour-coding by current rating is specified (examples: 10 A = red, 15 A = blue, 30 A = green) to aid identification.

Dimensions and designation

Full dimensional drawings and tolerances for Type K fuses and test fixtures. Example designation: Fuse-link ISO 8820–K–15.

Practical applications and users

Who uses ISO 8820-9:2014:

Automotive OEMs and Tier‑1 electrical designers selecting and specifying blade fuses for low-voltage circuits.

Fuse and fuse-holder manufacturers ensuring interchangeability and compliance.

Test laboratories validating fuse performance (voltage drop, breaking capacity, environmental robustness).

Quality and regulatory teams documenting component compliance for vehicle approvals.

Practical benefits:

Ensures consistent electrical and mechanical performance for Type K automotive fuses.

Supports safe overcurrent protection design for wiring harnesses and low-voltage vehicle electronics.

Facilitates component interchangeability and supplier qualification.
