About These Resources

EMC compliance is one of the most misunderstood stages in the product development cycle — and one of the most consequential. A poorly planned compliance program can mean schedule delays, unexpected retest costs, and missed market windows. These guides are written by Compatible Electronics' testing engineers to give manufacturers the practical knowledge they need to budget accurately, prepare effectively, and make informed decisions about their compliance strategy.

All resources are written from the perspective of an NVLAP accredited, ILAC MRA recognized laboratory that tests products daily against FCC, CE marking, IEC, ETSI, and other international standards.

Planning & Lab Selection

Understand what drives EMC testing costs and how to choose the right accredited laboratory for your project

EMC Testing Cost Guide: What Drives Pricing & How to Budget for Compliance

A detailed breakdown of every factor that determines EMC testing cost — from the number and type of tests required by each standard, to port count, EUT configurations, frequency range, and multi-market programs. Includes typical planning ranges for common programs (FCC SDoC, CE marking, IEC 60601-1-2 medical, IEC 61326-1 industrial) and explains how Compatible Electronics' shift-based pricing structure works by product type.

Typical cost ranges: $1,500 (simple FCC SDoC) to $25,000+ (complex multi-market industrial)
How shifts are determined by target market, product category, and port count

How to Choose an EMC Testing Laboratory: Accreditation, Capabilities & Red Flags

Not all EMC laboratories are equal. This guide explains what NVLAP accreditation, ISO/IEC 17025 certification, and ILAC MRA recognition actually mean — and why they matter for your CE marking Declaration of Conformity, FCC SDoC, and FDA ASCA submissions. Includes a practical checklist of questions to ask any lab before committing, and specific red flags that indicate a lab may not be suitable for your compliance program.

NVLAP vs. A2LA vs. ISO/IEC 17025 — what the difference means for your reports
ILAC MRA recognition — why it matters for CE marking and international acceptance

Test Preparation & Failure Prevention

What to bring, how to set up, and what causes the most common EMC test failures — and how to prevent them

Pre-Test Preparation · EUT Setup · Documentation

EMC Testing Preparation Checklist: What to Bring, Set Up & Define Before Your Test

A comprehensive pre-test preparation checklist covering everything you need to bring, configure, and document before your formal EMC test session. Covers EUT documentation requirements, cable and peripheral preparation, operating mode definition, performance criteria agreement, and on-site setup expectations. Following this checklist eliminates wasted chamber time and reduces the risk of incomplete or invalid test results.

Emissions Failures · Immunity Failures · Root Causes

Common EMC Test Failures: Causes, Root Causes & How to Prevent Them

An analysis of the most frequently occurring EMC test failures — radiated emissions exceedances, conducted emissions peaks, ESD-induced resets, EFT/Burst disruptions, and surge damage — with root cause analysis and practical design-level prevention strategies for each. Based on real failure patterns observed across thousands of test programs at Compatible Electronics.

Top radiated emissions failure causes — clocks, cables, PCB layout, filtering
Immunity failures most likely to require design changes vs. documentation fixes
When pre-compliance testing would have caught the failure earlier

Compliance Strategy

Making the right decisions about compliance approach — pre-compliance vs. formal testing, and navigating specialized regulatory programs like FDA ASCA

Pre-Compliance · Formal Testing · When to Use Each

Pre-Compliance vs Full Compliance EMC Testing: Differences, When to Use Each & Best Approach

A practical comparison of pre-compliance (engineering) testing and formal accredited compliance testing — what each produces, when each is appropriate, and how to structure a compliance program that uses both efficiently. Explains why pre-compliance testing in an accredited CISPR chamber (as Compatible Electronics offers) provides far better correlation to formal results than open-area or bench-top scanning.

What pre-compliance results can and cannot be used for
When to run pre-compliance first vs. going straight to formal testing
How to structure a phased program that minimizes total cost and retest risk

FDA ASCA Program Explained: How ASCA Recognition Accelerates 510(k) Medical Device Clearance

A complete explanation of the FDA Accreditation Scheme for Conformity Assessment (ASCA) — what it is, which laboratory accreditations qualify, how ASCA-recognized testing is submitted in a 510(k), and what the practical time and cost advantages are compared to non-ASCA submissions. Compatible Electronics holds FDA ASCA recognition for IEC 60601-1-2 Ed. 4 medical device EMC testing.
