UL's EMC pre-compliance services are designed to help customers identify potential EMC issues as effectively and efficiently as possible. By leveraging EMC's pre-compliance expertise early in the development process, costly errors can be avoided in design, and time to market can be accelerated.
What is EMC pre-compliance testing?
Electromagnetic compatibility (EMC) testing is a vital step in your product's development plan. EMC pre-compliance testing works to identify potential problems early in your design process before full-scale testing takes place. This gives you an incremental, stage-by-stage portrait of your product and its potential EMC-related design flaws, helping you avoid inconvenient product redesigns that can result when testing is put off until the final phase of the design plan.
Avoid failing full-scale EMC compliance testing
Here’s the key reason for pre-compliance testing: EMC testing outcomes are usually specific to a product’s design, meaning that EMC technicalities particular to a design plan can stop a product from passing. UL's EMC experts find that it’s not unusual for new products to fail initial full-scale compliance testing, which is why it offers EMC pre-compliance to help catch problems before full-scale testing is conducted.
Why do some designers put off EMC testing?
Due to stringent EMC regulatory requirements, some product designers may assume that EMC testing is a routine, one-size-fits-all process—that one designer’s product tests the same way as any other. Because of this, it’s not uncommon for designers to put off compliance testing until the end of the design cycle, which can lead to complications in compliance such as delayed launch dates, irritated customers and/or distributors, disrupted design plans, and additional fees to address the problem. EMC pre-compliance testing can help to avoid these unnecessary hiccups.
How EMC pre-compliance testing can save money?
EMC pre-compliance can help to steer clear of unanticipated spending by demonstrating where potential EMC issues might arise, giving both insight and time for efficiently planning the design steps. While it doesn’t test to full certification, pre-compliance can help identify potential hang-ups early in the process to help to avoid the cost of repeating full-scale testing. Other benefits may include:
Common technical causes of initial EMC test failures
Knowing common reasons that products fail EMC compliance can help to anticipate potential postponements, as well as keep customers in the loop during the pre-compliance process:
Key design considerations to increase the chance of passing EMC tests
Stay updated with strategies and troubleshooting that can help your product effectively move through both EMC pre-compliance and full-scale compliance testing. Increase the likelihood that your product meets compliance by familiarizing yourself with some of the common causes of initial EMC test failures, including:
