EMC testing services for medical devices and in vitro diagnostic medical devices.

EMC testing services for medical devices and in vitro diagnostic medical devices.

From July 2023, compliance with EMC standards for medical devices (JIS T 0601-1-2:2023) and various EMC standards for IVD devices will be implemented.

To manufacture and sell medical devices and in vitro diagnostic medical devices (IVD devices), it is necessary to meet international regulations and standards. The required criteria vary by country, and TÜV SÜD Japan provides testing and certification services, as well as training services, to comply with these regulations. In particular, EMC testing is an essential requirement for electrical and electronic devices, evaluating whether they emit unnecessary electromagnetic waves that interfere with the operation of other devices (emission) and whether they have the ability to withstand other electromagnetic interference (immunity). TÜV SÜD is accredited as a notified body based on EU directives for EMC testing, and the TÜV SÜD Japan Yonezawa Testing Laboratory (located in Yonezawa City, Yamagata Prefecture) is registered as an ISO/IEC 17025 accredited laboratory for domestic and international EMC standards.

[On-Demand Seminar] Evaluation of Human Exposure in 5G

[On-Demand Seminar] Evaluation of Human Exposure in 5G

I will provide a detailed explanation of SAR and power density measurements.

In recent years, the sale of 5G-equipped smartphones, the launch of local 5G services, and the planned sequential rollout of commercial services by major carriers since March 2020 have led to the full-scale implementation of 5G, the next-generation communication standard. 5G is characterized by ultra-high speed, ultra-low latency, and a large number of simultaneous connections, making it essential for promoting IoT applications such as autonomous driving in vehicles, smart factories, and the activation of the entertainment sector. There are high expectations for expansion and innovation not only in traditional communication fields but also in new areas and services. On the other hand, concerns about the impact of 5G on human health are also rising, and human exposure tests to determine whether electromagnetic waves emitted by communication devices such as smartphones, laptops, and GPS trackers have adverse effects on the human body are becoming increasingly important. In Japan and around the world, there is a growing demand for human exposure testing for portable wireless devices, and human exposure tests for 5G will be an unavoidable requirement for the future spread of 5G. In this seminar, we will explain not only SAR but also power density measurements necessary for 5G millimeter-wave compliance, and further introduce the testing services we offer.

Transformer inspection methods

Transformer inspection methods

Rich inspection content such as "pressure test" and "inter-layer dielectric strength test"! Introducing the inspection methods for transformers.

We conduct intermediate inspections, final inspections, and shipping inspections for transformers. In the "withstand voltage test," we check whether the insulation between the test subject and other parts maintains appropriate insulation capability. In addition to this, there are other tests such as "inter-layer dielectric strength test," "insulation resistance test," and other items tested during prototype production based on the validity of the design and customer requests. 【Inspection Contents】 ■ Withstand Voltage Test ■ Inter-layer Dielectric Strength Test ■ Insulation Resistance Test ■ No-load Current (Excitation Current) / No-load Loss (Iron Loss) ■ No-load Voltage *For more details, please refer to the PDF document or feel free to contact us.
