GSO ISO/TS 12025:2017 纳米材料 通过产生气溶胶来量化粉末中纳米物体的释放

This Technical Specification provides methodology for the quantification of nano-object release from powders as a result of treatment, ranging from handling to high energy dispersion, by measuring aerosols liberated after a defined aerosolization procedure. In addition to information in terms of mass, the aerosol is characterized for particle concentrations and size distributions. This Technical Specification provides information on factors to be considered when selecting from the available methods for powder sampling and treatment procedures and specifies minimum requirements for test sample preparation, test protocol development, measuring particle release and reporting data. In order to characterize the full size range of particles generated, the measurement of nano-objects as well as agglomerates and aggregates is recommended in this Technical Specification. This Technical Specification does not include the characterization of particle sizes within the powder. Tribological methods are excluded where direct mechanical friction is applied to grind or abrade the material.

GSO ISO/TR 14786:2017 纳米技术 为选定的纳米物体制定化学命名法的考虑因素

This Technical Report is intended to provide information and analyses in support of the development of chemical nomenclature for the naming of “nano-objects”. “Nano-objects” have been defined in ISO/TS 80004-1:2010 to mean “materials with one, two, or three external dimensions in the nanoscale”, with the nanoscale defined as the “size range from approximately 1 nm to 100 nm”. Nano-objects are further defined as nanoplates, nanofibres, and nanoparticles. More specifically, the nano-objects that are the subject of this Technical Report are discrete chemical entities rather than devices or mixtures (preparations). The nano-objects discussed in this Technical Report are not intended to constitute an exhaustive list. This Technical Report is intended to facilitate communications between developers and potential users of nomenclature including academia, industry, government and non-governmental organizations.

GSO IEC/TR 62632:2017 纳米级电接触和互连

This technical report describes a variety of nanoscale contacts and nano-interconnects used in research and development and in present-day products. The intent of this technical report is to identify nanoscale contacts and nano-interconnects that will be common in products, to describe the state-of-the-art and to describe some key features and issues related to these contacts. In particular, the following are discussed in each of the nanoscale contacts or nano-interconnects discussed in Clause 5: − type and configuration of the nanoscale contacts and interconnects formed; − requirements of the nanoscale contacts and interconnects in products; − fabrication technologies, processes, and process controls used to make the nanoscale contacts and interconnects; − characterization techniques used to quantify nanoscale contacts and nano-interconnects; − functionality and performance of nanoscale contacts and interconnects; − reliability of the nanoscale contacts and interconnects in products; and − expectations of when the product and the associated nanoscale contacts will reach the market.

GSO ISO/TS 12805:2017 纳米技术 材料规范 指定纳米物体的指南

This Technical Specification provides guidance on the preparation of specifications for the characteristics of manufactured nano-objects and their measurement methods. This is intended to help ensure the delivery of products with consistent properties for subsequent processing and/or final product performance. This Technical Specification includes guidance on specifying the physical and chemical characteristics of manufactured nano-objects, which might affect performance or subsequent processing. A list of applicable measurement methods is given in Annex B. NOTE 1 The nano-objects can be supplied in a dry form or as dispersions in a liquid medium. Guidance on specifying the environmental, health and safety (EHS) characteristics of manufactured nano-objects is outside the scope of this Technical Specification. NOTE 2 Nanotechnology is a rapidly growing and evolving field. It is therefore good practice for users of this Technical Specification to maintain an awareness of the legislative environment and latest developments in EHS regarding nanotechnology (see References [1][2][3][4][15][16][38][39][40][41][42][43]). If the customer or supplier wishes to assess the environmental, safety or health risks of the material, they can refer to ISO/TR 13121 and ISO/TR 12885 for further guidance. This Technical Specification also does not include guidance on specifying materials containing nanosized phases formed in situ by a transformation in the material, e.g. Guinier-Preston zones in precipitation hardening metals. Furthermore, it does not specify quantitative requirements for the object to be considered a nano-object, but lists appropriate examples of characteristics and properties and their measurement methods useful for specifying nano-objects. Characteristics and measurement methods for nano devices are not included. Although this Technical Specification refers to parameters, which could be considered aspects of material quality, it is not intended to provide guidance on the establishment of quality management systems. For guidance on quality management systems, reference can be made to ISO 9000.

GSO ISO/TR 16197:2017 纳米技术 人造纳米材料毒理学筛选方法的汇编和描述

This Technical Report provides a compilation and description of in vitro and in vivo methods that can be useful for the toxicological, including ecotoxicological screening of engineered and manufactured nanomaterials. Toxicological screening tests included in this Technical Report can be used for such purposes as early decision-making in research and product development, rapid feedback on potential toxicological/safety concerns, or for the preliminary assessment of manufactured nanomaterials. This Technical Report is divided between screening assays related to humans and screening assays related to the environment. A screening test is a relatively simple, inexpensive test that can be administered easily and provides an indication of potential adverse outcomes and effects on human health or the environment. The Technical Report is intended to complement other international efforts that address nanomaterial toxicology by focusing on screening methods suited for preliminary assessment and is not intended to duplicate similar efforts in other international organizations such as the Organization for Economic Cooperation and Development (OECD). If screening provides an early indication of hazard, the guidance will refer to other organizations’ approaches for full-scale toxicological assessment or further tiered studies.

1.1 This Standard describes test methods for characterization of base cellulose nanomaterials, specifically those designated as cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs) and cellulose microfibrils (CMFs). Note: These designations, particularly CNFs and CMFs, are not used consistently among cellulose nanomaterial producers and users; therefore there is some overlap as to which materials fall under which designation. 1.2 This Standard does not cover the characterization of cellulose microcrystals (CMCs). 1.3 This Standard does not cover cellulose nanomaterial-based nano-enhanced or nano-enabled products. Note: This Standard might be expanded in future editions as cellulose nanomaterial-enhanced and -enabled products move towards commercialization. See Annex C. 1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.5 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
