This standard also gives rules for determiningThe technical requirements for prefabricated tensioncomponents for assessingTheir safety, serviceability and durability.
The criteria laid down in this standard serve to evaluate the corrosion behaviour of unprotected metallic materials and coatings subject to galvanic corosion in sea water at ambient temperature. Since the chemical composition of the sea water as well as the extent and the type of fouling are not constant through all seasons and the mechanical loads acting on the corrosion behaviour can only be stated in terms of probability. Warranty claims cannot be derived from these normative criteria. Corrosion protection obtained by coatings as well as the cathodic corrosion protection are not subjects of this standard.
This European Standard specifies the weldability and brazeability of materials or material families used in the aerospace industry.
This European Standard specifies the weldability and brazeability of materials or material families used in the aerospace industry.
This document defines the rules to be observed to ensure the quality of aerospace structures in metallic materials by laser beam welding, implemented automatically, semi-automatically or manually. It is applicable without any restriction for the manufacturing of new parts or repair parts.
To update the terms and definitions to be used in CEN/TC 132 standards. The document defines general terms which are helpful for the communication within the aluminum industry and its customers relating to products of aluminium and aluminium alloys. Definitions in other standards applying to a particular field of application can be more specific than the definitions of identical terms in this standard; these can be found in the relevant standards.
This part of IEC 61191 specifies the evaluation criteria for voids on the scale of the thermal cycle life, and the measurement method of voids using X-ray observation. This part of IEC 61191 is applicable to the voids generated in the solder joints of BGA and LGA soldered on a board. This part of IEC 61191 is not applicable to the BGA package itself before it is assembled on a board.
This part of the IEC/TS 62647 series defines the objectives of, and requirements for, documenting processes that assure customers and regulatory agencies that ADHP electronic systems containing Pb-free solder, piece parts, and PWBs will satisfy the applicable requirements for performance, reliability, airworthiness, safety, and certifiability throughout the specified life of performance.
This European Standard defines the rules to be observed to ensure the quality of aerospace structures inmetallic materials by (solid reference number 521 and gas reference number 522 and diode laser Semiconductor523 according to EN ISO 4063) laser beam welding, implemented automatically, semi-automaticallyor manually.It is applicable without any restriction for the manufacturing of new parts or repair parts, these operations beingunder the responsibility of an approved design authority or repairer.
