ISO 21930:2017 provides the principles, specifications and requirements to develop an environmental product declaration (EPD) for construction products and services, construction elements and integrated technical systems used in any type of construction works. ISO 21930:2017 complements ISO 14025 by providing specific requirements for the EPD of construction products and services. ISO 21930:2017…

ISO 9849:2017 defines terms relating to geodetic field instruments only, e.g. distance meters, levels, theodolites and others, and their essential component parts which are normally used in terrestrial measuring operations of ordnance survey, topographic survey, plane survey and engineering survey. Therefore, terms concerning fields such as the following are not mentioned, for example,…

IEC 62481-2:2017(E) describes DLNA Media Format Profiles applicable to the DLNA Device Classes defined in IEC 62481-1-1:2017. Media Format Profiles are defined for each of the following Media Classes: Audio, Image, and AV. In addition, Profile ID values that identify media collections are also introduced. This third edition cancels and replaces the second edition published in 2013, and…

IEC 63080:2017(E) contains a list of currently used terminology to describe accessibility and terms that writers of standards need when writing and designing International Standards.
