Choice of equipment under test In the case of series-manufactured products, the equipment under test (EUT) shall be taken from the current production cycle. The choice of equipment under test shall be agreed with GL. If the equipment under test is a prototype, GL reserve the right to carry out subsequent comparative tests on series-manufactured products. 2. Test sequence There is no pre-defined test sequence. Before the start of the tests, the manufacturer shall determine the sequence and notify GL accordingly. All the tests required for the product shall be performed on one equipment under test. Any alternative arrangements are subject to consent. 3. Procedure of immunity tests to electromagnetic environment For these tests the EUT shall conform to its normal operational configuration, mounting and earthing arrangements and shall operate under mentioned test conditions. Particular interfaces of the EUT with the external electromagnetic environment are referred to as ports. The physical boundary of the EUT through which electromagnetic fields may radiate or impinge is the enclosure port. Differential tests (line/line) are those applied between electrical power, signal and control lines. Common mode tests (line/earth) are those applied between groups of lines and a common reference, normally earth. For the tests the results are evaluated against performance criteria relating to the operating conditions and functional specifications of the EUT, and defined as follows: performance criterion A: The EUT shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed, as defined in the relevant equipment standard and in the technical specification published by the manufacturer. Example of use: Equipment subject to the Rules for Classification and Construction except for the tests "Electrostatic Discharge, Conducted fast transients (burst) and Conducted slow transients (surge) ". performance criterion B: The EUT shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed, as defined in the relevant equipment standard in the technical specification published by the manufacturer. During the test, degradation or loss of function or performance which is self-recoverable is, however, allowed, but no change of actual operating state or stored data is allowed. Example of use: Equipment not subject to the Rules for Classification and Construction and the tests "Electrostatic Discharge, Conducted fast transients (burst) and conducted slow transients (surge)" for equipment subject to the Rules. performance criterion C: Temporary degradation or loss of function or performance is allowed during the test, provided the function is self-recoverable, or can be restored at the end of the test by the operation of the controls, as defined in the relevant equipment standard and in the technical specification published by the manufacturer: Example of use: Equipment not subject to the Rules for Classification and Construction.
