Full title and description

SAE J 1113-1-2023 — Electromagnetic Compatibility Measurement Procedures and Limits for Components of Vehicles, Boats (up to 15 m), and Machines (Except Aircraft) (16.6 Hz to 18 GHz). This standard specifies measurement procedures and limits for emissions and immunity testing of vehicle and machine components across the 16.6 Hz to 18 GHz range, and adopts several ISO/IEC documents by reference where noted.

Abstract

SAE J1113-1-2023 defines laboratory measurement methods and limits used to evaluate conducted and radiated emissions and immunity (including voltage-transient, audio-frequency and radio-frequency immunity) of components intended for vehicles, small boats (up to 15 m) and non‑aircraft machines. The document references international test methods (notably ISO 11452 series and IEC/CISPR guidance) in lieu of some legacy SAE J1113 parts and sets performance criteria and test arrangements appropriate for the automotive and related industries.

General information

Scope

The standard applies to measurement of voltage-transient immunity and, within the stated frequency range, audio (AF) and radio-frequency (RF) immunity tests as well as conducted and radiated emissions for components intended for land vehicles, small boats (up to 15 m) and machines excluding aircraft. Where appropriate, J1113-1 adopts ISO 11452 test methods for immunity and IEC/CISPR 25 for component emissions, and it documents specific exceptions or references for legacy SAE J1113 sub‑parts. Emissions from intentional radiators and immunity of commercial mains‑powered equipment to mains overvoltages are excluded from this document.

Key topics and requirements

• Measurement procedures for conducted and radiated emissions of vehicle and machine components across 16.6 Hz to 18 GHz.
• Immunity test methods covering voltage transients, audio-frequency (AF) and radio‑frequency (RF) immunity tests.
• Adoption-by-reference of ISO 11452 series test methods for component immunity and IEC/CISPR 25 for emissions measurements, with SAE‑documented exceptions where required.
• Test arrangements and instrumentation requirements (e.g., test chambers, coupling/decoupling networks, calibration and ground‑plane practices) appropriate for component‑level evaluation.
• Performance criteria and pass/fail assessment guidance for tested components under defined test levels and stimulus conditions.
• Applicability statements specifying vehicles, boats (≤15 m) and machines (excluding aircraft), and exclusions such as intentional radiators and mains-powered equipment immunity to overvoltages.

Typical use and users

Used by automotive and marine OEMs, component and subsystem suppliers, EMC test laboratories, design and validation engineers, and regulatory/compliance teams to define and perform component-level emissions and immunity testing during product development, supplier qualification and pre‑compliance verification.

Related standards

Part of the SAE J1113 family of EMC standards. J1113-1 references and aligns with ISO 11452 series (various parts for RF/immunity testing) and IEC/CISPR 25 for component emissions. Other SAE J1113 subparts (for example J1113/11 and J1113-41 and legacy J1113 parts) address more specific tests (conducted transients on power leads, component emission exceptions, etc.) and are commonly used in conjunction with J1113-1.
