The European edition of the transverse electromagnetic waveguide test is widely used in European laboratories as an economical alternative to a fully anechoic chamber, and it is particularly common during the development phase, when a product must be assessed repeatedly and the cost of chamber time would be prohibitive. The test is called up by the multimedia equipment standard and by several sector standards, which accept the method provided the field uniformity criteria are met. The European text reproduces the international description of the conventional cell and of the tapered gigahertz cell, the definition of the usable test volume and the procedures for emission and immunity testing, and it carries the foreword and annex that give the document its status under the directive. A report based on the cell method must include the field uniformity verification performed before the equipment was tested, since that record is what establishes the validity of the result.
