EVS-EN 2516:2020
Hind 8,72 EUR
Identne EN 2516:2020
Aerospace series - Passivation of corrosion resisting steels and decontamination of nickel base alloys
This standard specifies several chemical methods of passivation for corrosion resisting steels (austenitic, ferritic, martensitic and precipitation hardenable) and of decontamination for nickel or cobalt base alloys.

EVS-EN 4875:2020
Hind 7,38 EUR
Identne EN 4875:2020
Aerospace series - Surface treatments - Test method for measurement of electrical contact resistance
This document describes the electrical contact resistance testing method applicable to conductive and non-conductive coatings applied on test specimens made of conductive materials (unless otherwise specified) for aerospace applications. An objective of this practice is to define and control many of the known variables in such a way that valid comparisons of the contact properties of materials can be made. This test may be locally destructive depending on the process tested.

Air cargo equipment -- Restraint straps -- Part 2: Utilization requirements and recommendations and lashing calculations
This document aims at providing general utilization requirements and recommendations and calculation methods adequate to guarantee the effectiveness and ultimate load strength of tie-down/lashing arrangements performed to restrain cargo on board civil transport aircraft during flight: a) cargo loaded and tied down onto airworthiness approved air cargo pallets, themselves restrained into aircraft lower deck or main deck or upper deck cargo systems meeting the restraint requirements of air cargo pallets approved in accordance with ISO 8097 (NAS3610) or ISO 21100, or b) additional tie-down on aircraft structure when necessitated by pallet maximum gross mass or centre of gravity limits, or c) non-unitized individual pieces of cargo, or pieces of cargo placed onto an unrestrained ("floating") pallet into either lower deck, main deck or upper deck containerized cargo compartments of an aircraft, or d) individual pieces of load loaded in non-containerized (bulk loaded) baggage or cargo compartments. This document applies to cargo tie-down/lashing arrangements using exclusively air cargo restraint straps conforming to ISO 16049-1. Its general recommendations may also be used for tie-down arrangements using other means (e.g. steel cables, rope, other types of straps), but under the user's responsibility as to their adequacy and the strength calculations required. NOTE 1 Where tie-down is performed onto aircraft structure as per b) or c) above, additional restrictions can be stated in the aircraft's Authority approved Weight and Balance Manual. NOTE 2 The use of chains, rods, or other rigid devices for tie-down onto civil transport aircraft floor tracks, which can generate excessive stress in the aircraft structure, is not part of the scope of this document. . This document aims at providing industry recognized means of complying with Airworthiness Authorities general requirements applicable to load securing on board civil transport aircraft (see CCAR-25, JAS Part 3, 14 CFR Part 25 and EASA CS-25), and aircraft manufacturers Authority approved Weight and Balance Manuals for each aircraft type as specified therein. It is not the intent of this document to specify when restraint straps should be used, but how they should be used. Meeting the methods requirements of this document is not alone sufficient to ensure flight safety: this document is based on the assumption that cargo tie-down will be designed, performed, and checked prior to aircraft departure in accordance with appropriate operating instructions conforming to the Weight and Balance Manual of the aircraft concerned, by competent, suitably trained, personnel as defined for example in ISO 9001:2015, 6.2.2 (see Clause 8).

Space environment (natural and artificial) -- Operational estimation of the solar wind energy input into the Earth's magnetosphere by means of the ground-based magnetic polar cap (PC) index
This document provides guidelines for specifying the qualitative estimation of the solar wind energy input into the magnetosphere with use of operative ground-based information on the polar cap magnetic activity (PC index). The solar wind energy incoming into the magnetosphere predetermines development of the magnetospheric disturbances: magnetic storms and substorms. Magnetospheric disturbances include a wide range of phenomena and processes directly affecting human activity, such as satellite damage, radiation hazards for astronauts and airline passengers, telecommunication problems, outrages of power and electronic systems, effects in the atmospheric processes, and impact on human health. This document is intended for on-line monitoring the magnetosphere state and nowcasting the intensity and extent of magnetic disturbances as well as parameters of the high-latitude ionosphere. The method and accuracy of estimating is ascertained by close relationship between the PC index and interplanetary electric field (as the most geoeffective solar wind parameter), on the one hand, and between the PC index and magnetoshpheric disturbances, on the other hand.
