EMC/Safety Regulatory Research

EMC / Safety Regulatory Research

It can be a daunting task to identify the requirements of a particular region or market you intend to target. Understanding these requirements early helps your team make better decisions during the design and development process — and identifies opportunities to avoid redundant, costly re-testing by structuring one test program that satisfies multiple markets simultaneously.

What is EMC / Safety Regulatory Research?

EMC and safety regulatory research is the process of systematically identifying every applicable rule, regulation, standard, and authorization requirement that a product must satisfy for a given target market — and then analyzing how those requirements overlap with the requirements of other target markets so that a single, efficient compliance program can be structured to meet all of them.

Many regulations in different markets share common technical foundations — particularly in the EMC domain, where CISPR standards form the basis for FCC Part 15, CE marking (EN 55032), Canadian ICES-003, Australian AS/NZS CISPR 32, Japanese VCCI, and Korean KC simultaneously. By understanding these relationships early, tests can often be performed in a way that satisfies multiple market requirements from a single measurement set — avoiding potentially redundant and costly re-testing.

🌎 The Multi-Market Opportunity: A single CISPR 32 / EN 55032 radiated emissions measurement at our NVLAP accredited laboratory simultaneously satisfies FCC Part 15B (via ANSI C63.4), CE marking EMC Directive, ICES-003 Canada, AS/NZS CISPR 32 Australia/NZ, VCCI Japan, and KC Korea — from one test session at one California location.

Standards Cross-Reference — The Multi-Market Efficiency Opportunity

One of the most valuable outcomes of early regulatory research is identifying which standards share a common technical basis — allowing one set of measurements to satisfy multiple markets simultaneously:

Emissions — CISPR 32 Family

One Measurement, Six Markets

EN 55032 (2015)+A11(2020) — CE marking EMC Directive; accredited at all 3 CE locations
CISPR 32 Ed 2.0 — international base standard
AS/NZS CISPR 32 — Australia/NZ RCM scheme
VCCI-CISPR 32 — Japan voluntary compliance
CNS 15936 — Taiwan BSMI
KC — Korea (CISPR 32 technical basis)
ANSI C63.4 data also satisfies FCC Part 15B and ICES-003 from same measurements

Emissions — CISPR 11 Family

ISM Equipment Multi-Market

EN 55011 (2016)+A1(2017)+A11(2020) — CE marking; accredited at all 3 CE locations
CISPR 11 Ed 6.0 (2015) / Ed 6.1 (2015) — international; accredited at LF and Newbury Park
ICES-001 Canada — industrial ISM equipment (CISPR 11 basis)
AS/NZS CISPR 11 — Australia/NZ for ISM equipment

Immunity — IEC 61000-4 Series

Universal Immunity Foundation

IEC 61000-4-2 through 4-11 form the immunity test basis for CE marking, IEC 61326-1, IEC 60601-1-2, EN 50130-4, and most product family immunity standards
Immunity tests are generally harmonized internationally — one set of IEC 61000-4 results satisfies most global immunity requirements
Test levels and performance criteria vary by standard and environment — regulatory research identifies the most stringent combination to test to

Real-World Regulatory Research Examples

Smart Home Device — 8-Country Market Entry Research

A consumer electronics manufacturer planning a Wi-Fi 6E smart home hub launch in the US, EU, Canada, Australia, Japan, Korea, Taiwan, and Singapore engaged Compatible Electronics for regulatory research before beginning product development. The research identified that CISPR 32 formed the technical basis for all eight markets' EMC emissions requirements, that the EU additionally required EN 55035 immunity testing, and that Japan required VCCI self-declaration registration. The research further identified that a single NVLAP accredited test session at Compatible Electronics — using ANSI C63.4 for FCC Part 15B + EN 55032 for CE marking + collecting CISPR 32 data simultaneously — would satisfy the emissions requirements for six of the eight markets from one engagement. Korea (KC) and Taiwan (BSMI) required separate local authority submissions but could use the same test data. The research output structured the entire compliance program before the product entered PCB layout.

Industrial Sensor — EU vs. US Immunity Requirements Analysis

An industrial automation manufacturer was developing a 4–20 mA process sensor for both the US market (under IEC 61326-1 per customer specification) and the EU market (CE marking under EMC Directive). Regulatory research identified that IEC 61326-1 (2012) industrial environment immunity levels — 10 V/m radiated RF (IEC 61000-4-3), 10 Vrms conducted RF (IEC 61000-4-6), ±2 kV EFT/Burst (IEC 61000-4-4) — were more demanding than the CE marking generic standard EN 61000-6-2 levels. The research concluded that designing and testing to IEC 61326-1 industrial levels would simultaneously satisfy both market requirements — a single test program supporting both IEC 61326-1 compliance documentation and the CE marking technical file. The research also identified the specific performance criteria guidance in IEC 61326-1 Annex A for process control equipment that the manufacturer's engineering team needed to document before testing began.

Why Early Regulatory Research Matters

✓

Avoid Redundant Re-Testing

Understanding international standard equivalencies early allows one test program to satisfy multiple markets — avoiding separate test sessions for each country.

✓

Better Design Decisions

Knowing which tests and immunity levels apply before schematic design allows the engineering team to design to the most demanding requirement from the start.

✓

Accurate Compliance Budget

Early regulatory research produces an accurate compliance cost estimate — preventing budget surprises when unexpected test requirements are discovered post-prototype.

✓

Correct Labeling from Day One

Identifying labeling requirements early ensures the product enclosure, PCB silkscreen, and packaging meet every target market's marking requirements in the first production run.

✓

Standards Transition Awareness

Regulatory research identifies upcoming standard transitions — ensuring the compliance program uses the current version and avoids testing to a standard that will expire before product launch.

✓

40+ Years Research Experience

Compatible Electronics research is grounded in direct testing experience — we know which requirements are enforced by market surveillance, which are frequently misunderstood, and where the practical compliance risks lie.
