scope:
This part 4 of ETS 300 012 provides the test principles for the requirements of this ETS used to determine the compliance of an Implementation Under Test (IUT) to this ETS. It is outside the scope of this ETS to identify the specific tests required by an implementation where equipment has to meet attachment approval. Detailed test equipment accuracy and the specification tolerance of the test devices is not a subject of this ETS. Where such details are provided then those test details are to be considered as being an "informative" addition to the test description. Unless otherwise stated, conformance tests described in this ETS do not apply to the Auxiliary Power Supply (APS). This ETS is applicable to interface I A . The field of applicability is reported at the beginning of each test. Ideal values for components and circuits are considered in the test principles. Details concerning connection cords and general testing requirements can be found in annex A of this ETS.
