TS EN 62333-1

TS EN 62333-1 is a terminology standard for noise suppression sheets used with digital devices and equipment. It establishes the terms and definitions needed to describe electromagnetic noise suppression sheets in a common technical language, especially for applications in the 30 MHz to 30 GHz range. It also addresses the influence of such sheets on the signal and supports a uniform way of presenting product properties in manufacturers’ technical data.

Why the terminology matters

This part is not a performance test standard in itself; its value lies in defining the vocabulary used to identify, compare, and describe the material consistently. In general technical terms, a noise suppression sheet is a functional layer intended to help reduce unwanted electromagnetic energy in digital equipment, where signal integrity and electromagnetic compatibility are closely linked. Clear terminology matters because the same material property can be described in different ways unless a shared vocabulary is used.

Relationship to the rest of the standard family

The document is intended to be used together with IEC 62333-2, which means this first part provides the naming framework and presentation guidance, while the companion part covers the complementary technical content for the same product family. The TSE listing is based on EN 62333-1 and is currently withdrawn, but it remains relevant as a reference for understanding the terminology associated with electromagnetic noise suppression sheets.
