Prior to designing a process for use in an examination, a proper set of requirements should be produced, accepted by the client and recorded in accordance with good practice. This set of requirements should be derived from the requirements identified for the complete investigation and may include both functional and non-functional requirements. A requirement is a statement which expresses a need and its associated constraints and conditions. Conditions are measurable qualitative or quantitative attributes which can be used to qualify requirements. Constraints are restrictions on the design or implementation of the solution, such as interfaces to existing systems, physical size...11-28

4 Product certification 4.1 Concept of product certification 4.1.1 Product certification is the provision of assessment and impartial third-party attestation that fulfilment of specified requirements has been demonstrated. Product certification is carried out by product certification bodies which should conform to ISO/IEC 17065. Specified requirements for products are generally contained in standards or other normative documents. 4.1.2 Product certification is an established conformity assessment activity that provides confidence to consumers, regulators, industry and other interested parties that products conform to specified requirements, including for example product performance, safety, interoperability and sustainability. 4.1.3 Product certification can facilitate trade, market access, fair...11-28

The largest part of the market of mass production equipment is in nanostructure thin film materials, as well as tools, moulds and various mechanic parts. At present, equipment companies operating worlwdie (e.g. Kobe, Cemecon, Balzers, Huazer 2 ) have developed their equipment and handled materials, processes and patents collectively. The market of nanocomposite materials is led by polymer matrix nanocomposites, with a world market size of about 5 billion – 7 billion US dollars in 2009. The market of ceramic nanocomposite materials was about 2,5 billion US dollars after 201 0. The market has shown a consistent growth trend due...11-28

6 How to act in the presence of a thunderstorm 6.1 How to detect a lightning risk Advance information on the probability and corresponding approach of lightning is available from local weather forecasts in many regions and internet sites are available to provide near real-time lightning location information. Lightning warning systems can also be used, both for industrial sites and private activities. Networks of detectors exist in some countries and provide, by internet or by other means (such as fax, phone, e-mail, dedicated communication lines), a warning of the occurrence of a lightning event. A dangerous industrial activity can be...11-28

IEC TR 62658-2013 pdf Roadmap of optical circuit boards and their related packaging technologies
2.3 Planar embedded optical waveguides It is proposed that the resulting performance bottleneck due to the electrical constraints described above be substantially reduced by conveying high-speed data optically instead of electronically. This requires that optical channels be incorporated into the system at the printed circuit board (PCB) level. While many technology solutions have been put forward and commercially deployed to support embedding conventional optical fibres onto printed circuit boards, there has been a great deal of research and development activity centred in Europe looking at the fabrication and deployment of planar optical waveguide channels on/ in printed circuit board substrates[1...11-28 -
1 Scope The texture map for auditory presentation of printed texts is printed on paper or shown on display devices. This International Standard specifies the printing quality of this texture map on paper. In order to ensure an interoperability of the texture map specified in IEC 62665, a printing specification based on the quality of this International Standard should be employed. 2 Normative reference The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the...11-28

6.3 Internal short circuit An OLED panel with internal short circuit shall not cause any hazard. Compliance is checked by the following test: An internal short circuit shall be provoked intentionally in the OLED panel under test according to instructions given by the manufacturer or according to a method described in Annex C. The location of this internal short circuit shall be close to the edge of the light output area at around 2 mm distance. Before starting the test, the test sample of the OLED panel shall not be operated. The test sample of the OLED panel shall be...11-28 -

IEC 62858-2015 pdf Lightning density based on lightning location systems (LLS) – General principles
5 Validation of lightning location system performance characteristics The performance characteristics of an LLS determine the quality of the lightning data available. These performance characteristics include: – detection efficiency for IC and CG flashes and CG strokes; – location accuracy; – peak current estimation accuracy; and – lightning classification accuracy. As stated in Clause 4, for N G and N SG determination of CG flash DE, LA, and lightning, classification accuracy is of primary importance. These performance characteristics can be evaluated using a variety of techniques which are summarized below. a) Network self-reference: In this technique, statistical analysis of parameters...11-28
