EVS-EN 4691-2:2018
Hind 8,01 EUR
Identne EN 4691-2:2018
Aerospace series - Tie rod with integrated bolts - Part 2: Overview construction kit
This European Standard presents the construction kit of rod assemblies for aerospace applications with two adjustable ends with integrated bolts for interior and sub structure in the temperature range −55 °C to 85 °C.

EVS-EN 4533-004:2018
Hind 15,40 EUR
Identne EN 4533-004:2018
Aerospace series - Fibre optic systems - Handbook - Part 004: Repair, maintenance, cleaning and inspection
The handbook gives guidelines related to ‘Fault analysis and repair’ as well as ‘maintenance and inspection of fibre optic links. The first deals with what to do when something goes wrong – how to go from a fault notification to locating the fault, and finally, repairing it. The second covers the recommended procedures for upkeep and maintaining harness health over the lifetime of its installation.

EVS-EN 3475-604:2018
Hind 8,72 EUR
Identne EN 3475-604:2018
Aerospace series - Cables, electrical, aircraft use - Test methods - Part 604: Resistance to dry arc propagation
This European standard specifies a method for appraising the behaviour of cable insulation when an electric arc is initiated and maintained by two powered cables rubbing against a blade. This European Standard shall be used together with EN 3475 100. The primary aim of this test is: — to produce, in a controlled fashion, continuous failure effects which are representative of those which may occur in service when a typical cable bundle is damaged by abrasion such that electrical arcing occurs, both between cables and between cables and conductive structure, and — to examine the aptitude of the insulation to track, to propagate electric arc to the electrical origin. Originally defined for 115 Vac network, this test also proposes conditions for 230 Vac network. Unless otherwise specified in product standard, only 115 Vac conditions shall be satisfied. Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 7). It is generally agreed that larger sizes need not be assessed since the short-circuit phenomenon becomes dominant at low line impedances. Unless otherwise specified in the technical/product standard sizes 002, 006 and 020 cable shall be assessed.

EVS-EN 3475-605:2018
Hind 8,01 EUR
Identne EN 3475-605:2018
Aerospace series - Cables, electrical, aircraft use - Test methods - Part 605: Wet short circuit test
This European Standard specifies a method for appraising the behaviour of cable insulation subjected to an electric arc initiated and maintained by a contaminating fluid. This European Standard shall be used together with EN 3475-100. The primary aim of this test is: to produce, in a controlled fashion, continuous failure effects which are representative of those which may occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination such that electrical arcing occurs between cables; to examine the aptitude of the insulation to track to propagate electric arc to the electrical origin. Originally defined for 115 Vac network, this test also proposes conditions for 230 Vac network. Unless otherwise specified in product standard, only 115 Vac conditions shall be satisfied. Six (6) levels of prospective fault current have been specified for concerned cable sizes (see Clause 7). It is generally agreed that larger sizes need not be assessed since the short-circuit phenomenon becomes dominant at low line impedances. Unless otherwise specified in the technical/product standard sizes 002, 006 and 020 cable shall be assessed.

EVS-EN 4533-004:2006
Identne EN 4533-004:2006
Aerospace series - Fibre optic systems - Handbook - Part 004: Repair, maintenance and inspection
The original task headings in the Fibre Optic Harness Study were ‘Inspection and Fault Analysis’ and ‘Repair and Maintenance’. However, to create a more coherent and readable handbook these have been re-arranged in this part of EN 4533 to make two new topic headings – ‘Fault analysis and repair’ and ‘Scheduled maintenance and inspection’.
