This document specifies the minimum requirements for airworthiness approval of air cargo pallets, nets and containers, generally designated as air cargo unit load devices (ULD). This document is intended to provide a uniform technical reference for air cargo unit load devices approval. As a prerequisite, it is presupposed that the applicable general civil aviation requirements and the aircraft manufacturer’s approved Weight and Balance Manual are followed. This document defines the minimum performance requirements and test parameters for air cargo unit load devices requiring approval of airworthiness for installation in an approved aircraft cargo compartment and restraint system that complies with the cargo restraint and occupant protection requirements of CCAR 25, EASA CS-25 or 14 CFR Part 25, except for the 9,0 g forward ultimate inertia force of § 25.561 (b) (3) (ii). This document applies to airworthiness approved air cargo unit load devices intended for carriage on board civil transport category airplanes type certificated under CCAR 25, EASA CS-25 or 14 CFR Part 25, or equivalent. This document exclusively applies to unit load devices airworthiness approval and testing parameters. It does not apply to aircraft design or aircraft operating requirements, which are provided by the approved Weight and Balance Manual for each aircraft type. Other aspects that do not directly pertain to air cargo unit load devices airworthiness approval and testing are not covered by this document and are defined in other International Standards (see Bibliography), e.g.: Air cargo unit load devices qualified prior to publication of this document were approved in accordance with the requirements of ISO 8097:2001. This document is intended as a TSO approval reference for all new models of unit load devices in the sizes and types it covers, in replacement of ISO 8097. For air cargo unit load devices, the size or type of which is not covered in this document, see the requirements of ISO 8097:2001, if their size or type is contained therein, or other equivalent criteria, if not.

ISO 28079:2009 specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. ISO 28079:2009 applies to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and carbonitrides (normally called hardmetals, cermets or cemented carbides). The test procedures proposed in ISO 28079:2009 are intended for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures proposed in ISO 28079:2009 are also intended for use in a normal laboratory-air environment. They are not intended for use in corrosive environments, such as strong acids or seawater.

 

ISO 13916:2017 specifies requirements for the measurement of preheating temperature, interpass temperature and preheat maintenance temperature for fusion welding. ISO 13916:2017 can also be applied as appropriate in the case of other welding processes. ISO 13916:2017 does not cover the measurement of post weld heat treatment temperatures.

This document describes publish-subscribe architecture on ship-shore data communication and is intended for use by system providers and users, such as software vendor, platform developer, fleet manager, application user in the field of the shipbuilding industry, shipping companies, equipment manufacturers, port and on-shore service providers, to communicate in the publish-subscribe architecture between ship and shore. There requires the architecture as a growing need for the vessel in order to deal with the interoperability of applications and systems, and to address the streaming service within ships. For this purpose this document might be compatible with the interoperability of smart applications for ship and the shipboard data servers to share field data at sea, however, this document focuses on sharing data between ship and shore.

This document specifies procedures for statistical analysis and rating of non-metallic inclusions (simplified into inclusions in the following) using scan­ning electron microscope (SEM) with energy dispersive X-Ray spectrometer (EDS) and automatic image analysis capabilities. When this method is used to rate inclusions, it can produce the same ratings as ISO 4967 and is intended for inclusions above 2µm in rolled or forged steel products having a reduction ratio of at least 3. When this document is used for statistical analysis, it can be applied to all size of inclusions in a variety of billets or rolled steels.

 

 

This document specifies a procedure to determine the release of metals from metallic materials used in products intended to come into contact with drinking water. The test can be used for three purposes: a) To assess a material as a reference material for a new category of materials by metal release testing using the results of several investigations in different waters covering a broad range of water compositions; b) To assess a material for an existing category for approval by way of metal release testing using the water defined in part 2, which exhibited the highest metal release when the reference material of the category was tested; c) To obtain data on the interaction of local water with a material.

 

This document specifies a method for the measurement of focal spot dimensions within the range of 5 µm to 300 µm of X-ray systems up to and including 225 kV tube voltage. This determination is based on the evaluation of an image with a dedicated focal spot that has been radiographically recorded using an edge and evaluated with a digital method. The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular the size and the two-dimensional intensity distribution as seen from the detector plane. For the characterization of commercial X-ray tube types (i.e. for advertising or trade) the specific maximum values of Annex A are preferred. NOTE The same procedure can be used at higher kilovoltages by agreement but the accuracy of the measurement can be poorer.
