In 2006, the United States developed ISO 16792-2006 Technical product documentation-Digital product definition data practices adopted from the ASME Y14.41-2003 Digital product definition data practices. It was then revised and improved continuously. This standard is the basic standard for the three-dimensional digital design, which specifies how to add attributes, annotations, and other information to the design model to achieve a digital definition of the product. However, we believe that the way of modelling as well as the sequence and general requirements of modelling are of equal importance for reflecting design intent properly. Therefore, we propose a new international standard work item proposal to stipulate the construction, application and management requirements for the design model in the three-dimensional digital design process of mechanical products, which expressed as follows: 1) General requirements, including terms and definitions related to three-dimensional modelling, classification and composition of three-dimensional digital model, the naming principle of three-dimensional model files, definition and classification of geometric modelling features; 2) General process and requirements for part modelling, including common parts and specific parts, such as polymorphic parts, flexible parts and others; 3) General process and requirements for assembly modelling, including assembly level definition, assembly constraint definition, management of assembly structure tree, assembly model packaging and other requirements; 4) Model application management requirements, including basic requirements for model checking, model release, model data management, and the technical status management.

ISO 25178-71:2017 defines Type S1 and Type S2 software measurement standards (etalons) for verifying the software of measuring instruments. It also defines the file format of Type S1 software measurement standards for the calibration of instruments for the measurement of surface texture by the areal method as defined in the areal surface texture chain of standards, chain link G. NOTE Throughout ISO 25178-71:2017, the term "softgauge" is used as a substitute for "software measurement standard Type S1".

This document specifies requirements for roofing and cladding products used for assembly into coverings for wall claddings, linings and pitched roofs, made from aluminium sheet with or without additional surface treatment (organic coating or anodising). This document establishes general characteristics, definitions and labelling of the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. Products can be prefabricated or semi-formed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs). This document applies to all discontinuously laid and fully supported roofing and cladding products made of aluminium sheets. No requirements for supporting construction, design of roof system and execution of connections and flashings are included. This document does not apply to self-supporting aluminium sheets that are covered by EN 508-2:-.
