The work of preparing International Standar

    11、ds is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take

    12、 part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In part

    13、icular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of t

    17、 complexity of technical solutions and products requires new approaches. Classic research and development methods and innovation approaches often reach their limits, especially in the development and optimization of materials, structures, and components. The identification of suitable biological pri

ISO 2016 All rights reserved vBS ISO 18457:2016BS ISO 18457:2016Biomimetics Biomimetic materials, structures and components1 ScopeThis International Standard provides a framework of biomimetics for the development of materials, structures, surfaces, components, and m

    20、anufacturing technologies.This International Standard specifies the principles of biological systems, and especially the performance of biological materials, structures, surfaces, components, and manufacturing technologies that provide the motivation and reasons for biomimetic approaches. It specifi

    21、es the methodology based on analysis of biological systems, which lead to analogies, and abstractions. The transfer process from biology to technology is described based on examples of biomimetic materials, structures, surfaces, components, and manufacturing technologies. This International Standard

    22、 describes measurement methods and parameters for the characterization of properties of biomimetic materials. This International Standard provides information on the relevance of biomimetic materials, structures, surfaces, components, and manufacturing technologies for industry.This International St

    23、andard also links to other subareas in biomimetics because fundamental developments in materials, structures, surfaces, components, and manufacturing technologies often form the basis for a wide variety of additional innovations. It provides guidance and support for all those who develop, design, pr

    24、ocess, or use biomimetic materials, structures, surfaces, components, and manufacturing technologies. This International Standard can also serve for those who want to learn about and investigate these topics.2 Normative referencesThe following documents, in whole or in part, are normatively referenc

ISO 2016 All rights reserved 3BS ISO 18457:2016ISO 18457:2016(E)Technical materials rely mostly on chemistry for their properties whereas biological materials rely on structure and are almost invariably composite.Owing to their hierarchical structure from the molecular to the macroscopic level,

    42、 it is not possible to clearly distinguish between the terms “material” and “structure” in the field of biology. For this reason, the term “material” is used in the following as a general term for all biological materials with their respective structures.Some characteristics of biological materials

    43、that are relevant to biomimetic implementations are listed in Table 1.Table 1 Characteristics of biological materialsCharacteristics Biological Example ExplanationsPropertiesMultifunctionality Wood: integration of water pipes, strength, damping, storage, among other thingsBiological materials are of
