This document defines the rules to be applied for symbolic representation of welded joints on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. The principles of this document can also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In this document:
— clauses, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line;
— clauses, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line;
— clauses, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.
The symbols shown in this document can be combined with other symbols used on technical drawings, for example to show surface finish requirements.
An alternative designation method is presented which can be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements.
NOTE Examples given in this document, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles.

ISO 1924-2:2008 specifies a method for measuring the tensile strength, strain at break and tensile energy absorption of paper and board, using a testing machine operating at a constant rate of elongation (20 mm/min). ISO 1924-2:2008 also specifies equations for calculating the tensile index, the tensile energy absorption index and the modulus of elasticity.
Testing in conformance with ISO 1924-2:2008 always includes the measurement of tensile strength. Measurement or calculation of other properties is subject to agreement between the parties concerned.
ISO 1924-2:2008 is applicable to all papers and boards, including papers with a high strain at break if the results are within the capacity of the testing machine. It also applies to the components of corrugated board but not, however, to corrugated board itself.

ISO 7198:2016 specifies requirements for the evaluation of vascular prostheses and requirements with respect to nomenclature, design attributes and information supplied by the manufacturer, based upon current medical knowledge. Guidance for the development of in vitro test methods is included in an informative annex to ISO 7198:2016. It can be considered as a supplement to ISO 14630:2012, which specifies general requirements for the performance of non-active surgical implants.
NOTE Due to the variations in the design of implants covered by ISO 7198 :2016 and, in some cases, due to the relatively recent development of some of these implants (e.g. bioabsorbable vascular prostheses, cell based tissue engineered vascular prostheses), acceptable standardized in vitro tests and clinical results are not always available. As further scientific and clinical data become available, appropriate revision of ISO 7198 :2016 will be necessary.
It is applicable to sterile tubular vascular grafts implanted by direct visualization surgical techniques as opposed to fluoroscopic or other non-direct imaging (e.g. computerized tomography or magnetic resonance imaging), intended to replace, bypass, or form shunts between segments of the vascular system in humans and vascular patches intended for repair and reconstruction of the vascular system.
Vascular prostheses that are made of synthetic textile materials and synthetic non-textile materials are within the scope of ISO 7198:2016.
While vascular prostheses that are made wholly or partly of materials of non-viable biological origin, including tissue engineered vascular prostheses are within the scope, ISO 7198:2016 does not address sourcing, harvesting, manufacturing and all testing requirements for biological materials. It is further noted that different regulatory requirements might exist for tissues from human and animal sources.
Compound, coated, composite, and externally reinforced vascular prostheses are within the scope of ISO 7198:2016.
Endovascular prostheses implanted using catheter delivery and non-direct visualization are excluded from the scope of ISO 7198:2016. It includes information on the development of appropriate test methods for graft materials, referenced in ISO 25539‑1 for materials used in the construction of endovascular prostheses (i.e. stent-grafts).
NOTE Requirements for endovascular prostheses are specified in ISO 25539‑1.
The valve component of valved conduits constructed with a tubular vascular graft component, and the combination of the valved component and the tubular vascular graft component, are excluded from the scope of ISO 7198:2016. It can be helpful in identifying the appropriate evaluation of the tubular vascular graft component of a valved conduit but specific requirements and testing are not described for these devices.
Cardiac and pericardial patches, vascular stents, accessory devices such as anastomotic devices, staplers, tunnelers and sutures, and pledgets are excluded from the scope of ISO 7198:2016.
NOTE Requirements for vascular stents are specified in ISO 25539‑2.
Requirements regarding cell seeding are excluded from the scope of ISO 7198:2016. Tissue engineered vascular prostheses that contain or are manufactured using cells present many distinct manufacturing (e.g. aseptic processing, cell seeding, etc.) and testing issues than those produced with synthetic or non-viable biological materials. The in vitro testing requirements that are outlined in ISO 7198:201

This document provides terminology, concepts, requirements, and guidance for logging of AI systems.
It is primarily intended for organizations placing on the market or putting into service AI systems and is not specific to any particular sector.

This document specifies the technical conditions for inspection and delivery of wrought aluminium and wrought aluminium alloy sheet, strip and plate for general applications. It also includes provisions for ordering and testing.
It applies to products with a thickness over 0,20 mm up to and including 400 mm.
For many special applications of aluminium strip, sheet and plate, specific European Standards exist, where different or additional requirements are formulated and the appropriate alloys and tempers are selected: see Annex A. Most of these special European Standards refer to provisions of this document.
The selection of the relevant special European Standards is under the responsibility of the purchaser.
Specific European Standards are available for applications involving special properties, such as corrosion resistance, toughness, fatigue strength, surface appearance or welding properties.
