This document specifies the characteristics, qualification and acceptance requirements for bolts with MJ threads in NI-PH2601, passivated, for aerospace applications. Classification: 1 550 MPa1/650 °C. It is applicable whenever referenced.

 

1.1 In scope This document defines a Recommended Practice for Product Structure validation. The objective is to validate the product structure of data ingested, extracted or re-used by the archive. This document defines a method to uniquely identify each node in the product structure and to uniquely define the structure of each assembly node. 1.2 Out of scope This document will not provide validation properties for documents; CAD or other.

 

This document specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for non-latching electromagnetic, hermetically sealed relays intended for use in a temperature range from - 55 °C to 125 °C continuous.

 

This document specifies characteristics for 10 A aerospace relays with the following variations of mounting means (e.g. vertical, horizontal), terminal styles (e.g. hooks, pins for soldering, pins for sockets) the associated finishing (e.g. tin plated, gold plated) and coil voltages (e.g. 6 VDC 12 VDC 28 VDC 48 VDC, 115 VAC) for relays with 2, 4 or 6 poles and with or without internal suppressors or LIE protection. The built-in suppressor limits the voltage transients resulting from the electrical power shut off. The relay sockets are not described in this document.

 

This document specifies the test procedures of electromechanical all-or-nothing relays for use in aircraft electrical systems to EN 2282. This document represents the aeronautical version of the standard EN 116000-3 from which it draws inspiration.

 

This document specifies the requirements for determining fatigue crack growth rates using corner-crack (CC) test pieces. Crack development is measured using a potential-drop system, and the calculated crack depths can be corrected via marker bands created on the fracture surface during the test. Results are expressed in terms of the crack-tip stress-intensity range (?K), with crack depths and test stress level noted.

 

This document specifies safety requirements which need to be observed at design, calculation, manufacture, installation, maintenance, of mobile, temporary installed tents with more than 50 m2 ground area. This document applies also to multiple small tents which are normally not covered by this document and will be installed close together and exceed 50 m2 in sum. NOTE Information is given in Annex C on examination and approval.

 

This document specifies business requirements for processes intended to preserve digital data. NOTE Data are stored and maintained for the purpose of retrievability and usability during the required archiving period. In addition, for the purpose of some business requirements, data are authentically preserved and accessed. This document is intended to allow for different implementations based on a company’s specific business environment. This document is not intended to incorporate company specific requirements and does not dictate specific organizational structures within a company. This document does not specify a design or an implementation of an archive system. Actual implementations can distribute responsibilities or break out functionality differently. This document assumes that all requirements for configuration management of the product data are in place and therefore are not specifically described in this document.
