While the ”circuit integrity FE“ provides only for the test single cables, the cables here are tested connection with practical fixing systems. important appreciate that there connection between the two standards, circuit integrity (FE) and system circuit integrity (E).

Remark: This test not equivalent the test for functional integrity according DIN 4102-12
Test Circuit integrity electrical cable installations
This standard describes the requirements and the actions for the achievement the functional integrity electrical cable installations the event fire.020 (Rf1, Rf11/2))
Better than the standard! This test (E30-E90) now the world wide standard for guaranteeing functional integrity the complete electrical cable installation, including the fixing components, under normal operating conditions. Cables which fulfil the requiremetns this test are marked with <<FE180>> after their type designation. The test carried out and certified from state recognised institutes
