Electromagnetic Compatibility Testing

About HTW Laboratory:

We offer professional EMC testing at a lower cost than other labs. Our customized testing solutions can enhance process efficiency and reduce testing cycles. For technical regulation support, technicians at HTW are able to help you understand technical regulations and product design specifications. Communicate with our experts to determine your needs and we will provide you with a free evaluation, proposal and quotation.

The importance of EMC testing for you and your users:

Our full-service EMC laboratories are accredited by numerous regulatory agencies, governments and the International Laboratory Accreditation Cooperation (ILAC), making us a recognized accreditation body in all major markets. We'll analyze the ability of your electronic devices to operate as expected in proximity to other electronic devices or in the presence of electromagnetic emissions. We'll guide you through every step of the compliance process to help confirm your products meet EMC requirements in your target markets.

EMC Certification Items:

European: CE-EMC/ E-Mark/ CE-R&TTE/ E-Mark/ TUV-EMC
Asian: China-
CCC/ Taiwan-BSMI/ Japan-VCCI/ Korea-KC
America: USA-

Canada: IC

Australia: C-RCM

Causes of EMI and the role of EMC testing:

Electronic devices and radio systems can suffer effects resulting from unintended electromagnetic interactions and/or equipment emissions, known in the industry as electromagnetic interference (EMI). For this reason, many countries require new products to comply with electromagnetic compatibility (EMC) before launch. EMC compliance testing helps to prevent EMI, can resolve underlying design flaws and position you and your product toward market access.
