prEN 3475-605 Viešoji apklausa

Komentavimo iki data 2024-12-21

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 605: Wet short-circuit test

This document specifies a method for appraising the behaviour of cable insulation subjected to an electric arc initiated and maintained by a contaminating fluid. This document is intended to 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 can occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination such that electrical arcing occurs between cables; 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. However, for 230 VAC test condition only, the test EN 3475-605 can overrule and be applied as test governance as it has been demonstrated that test EN 3475-605 is more stringent, repeatable and reproductible compared to EN 3475-604 and EN 3475-603. Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 8). It is 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 are assessed.

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 604: Resistance to dry arc propagation

This document specifies a method for appraising the behaviour of cable insulation when an electric arc is initiated and maintained by two (2) powered cables rubbing against a blade. This document is intended to 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 can occur in service when a typical cable bundle is damaged by abrasion such that electrical arcing occurs, both between the 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. However, for 230 VAC test condition only, the test EN 3475-605 can overrule and be applied as test governance as it has been demonstrated that test EN 3475-605 is more stringent, repeatable and reproductible. Unless otherwise specified in the product standard, only 115 VAC conditions are satisfied. Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 8). It is 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 are assessed.

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 603: Resistance to wet arc tracking

This document specifies a method of assessing the behaviour of cable insulation subject to an electric arc initiated and maintained by contaminating fluid along the surface of the insulation. This document is intended to 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 can occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination. Electrical arcing occurs along the surface of the insulation between damage sites on adjacent 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. However, for 230 VAC test condition only, the test EN 3475-605 can overrule and be applied as test governance as it has been demonstrated that test EN 3475-605 is more stringent, repeatable and reproductible. Unless otherwise specified in the product standard, only 115 VAC conditions are satisfied. Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 8). It is agreed that sizes larger than 051 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 are assessed.

This document specifies the conditions for the determination of uniaxial tensile properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at elevated temperature in air, vacuum or inert gas atmospheres. This document is specific to the tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This document provides information on the axial tensile properties and stress-strain response in temperature, such as axial tensile strength, axial tensile strain at failure and elastic constants. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. It applies primarily to all ceramic matrix composite tubes with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bidirectional (2D braid and weave) and multi-directional (xD, with x > 2), tested along the tube axis.

This Document specifies a method for the determination of total moisture content of solid recovered fuels (SRF) by drying a sample in an oven. This method is suitable for use for routine production control on site, e.g. if a high precision of the determination of moisture content is not required. It is applicable to all solid recovered materials including solid recovered fuels. NOTE 1 The total moisture content of solid recovered materials including solid recovered fuels is not an absolute value and therefore standardised conditions for its determination are indispensable to enable comparative determinations. NOTE 2 The term moisture content when used with SRF can be misleading since these materials often contain varying amounts of volatile compounds (extractives) which can evaporate if determining moisture content by oven drying.

This document specifies requirements and test methods of valve-actuator assemblies in individual zone control of water-based HVAC applications. Control valves of nominal diameter larger than DN50 are currently not covered by this document. Within the scope are pressure independent and pressure dependent control valve-actuator assemblies of relevant categories: 2-port, 3-port and 6-port valves (if they incorporate a control valve function). Where a certain control loop as a combination of controller and valve-actuator assembly was assessed under EN 15500-1:2017, this European Standard allows the assessment of the performance of combinations of that controller with different valve-actuator assemblies. The tests in this document ensure that valve/actuator assemblies, as components of control loops, can be replaced with products that provide comparable or better performance. In hydronic system, valve-actuator assembly is a component of control loop that controls water flow rate according to the application control demand. The common Formula (1) describing the flow rate where whole hydronic system itself has an influence on actual flow rate as differential pressure across control valve-actuator assembly typically varies during operation.
