ISO 11452-5 describes the stripline method within the ISO 11452 series of component test methods for narrowband radiated electromagnetic energy. A stripline is a parallel conductor arrangement in which the component and its harness are placed in the well defined field formed between the conductors, and it provides an economical and repeatable way of testing modules at frequencies where the field is reasonably uniform. The standard defines two configurations, the 150 mm stripline used for small equipment and the 800 mm stripline able to accommodate larger modules and their wiring, and it gives the dimensions, the characteristic impedance and the terminating arrangement of each. It specifies the field strength generated for a given input power, the method of calibrating that relationship, the positioning of the equipment under test relative to the conductors, and the maximum dimensions the equipment may have in order to remain within the uniform field region. As with the other methods, the harness construction and the grounding of the module must be controlled.
