Buildings and building-related facilities — Functional and user requirements and performance — Tools...
ISO 11863:2011 specifies how to determine functional performance requirements (demand) for buildings and building-related facilities, and how to check the capability of buildings and facilities to meet identified requirements (supply). It specifies how to determine the relative importance of each requirement, establish thresholds for capability, and evaluate the significance of differences…
Document management — Electronic document file format for long-term preservation — Part 2: Use of I...
ISO 19005-2:2011 specifies the use of the Portable Document Format (PDF) 1.7, as formalized in ISO 32000-1, for preserving the static visual representation of page-based electronic documents over time.
ISO 19005-2:2011 is not applicable to
specific processes for converting paper or electronic documents to the PDF/A format,
specific technical design, user interface, implementation,…
ISO/TS 11356:2011 specifies the relevant spray operation parameters for recording information necessary for traceability, and provides a basis for the development of systems for automatically collecting and reporting agricultural production data. The parameters can also be valid for other records, such as those related to spraying in amenities. The intended users include machine manufacturers,…

Miscellaneous lampholders - Part 1: General requirements and tests
IEC 60838-1:2004+A1:2008+A2:2011 applies to lampholders of miscellaneous types intended for building-in (to be used with general purpose light sources, projection lamps, floodlighting lamps and street-lighting lamps with caps as listed in annex A) and the methods of test to be used in determining the safe use of lamps in lampholders. This part of IEC 60838 also covers lampholders which are…
IEC 60238:2004+A1:2008+A2:2011 applies to lampholders with Edison thread E14, E27 and E40, designed for connection to the supply of lamps and semi-luminaires* only. It also applies to switched-lampholders for use in a.c. circuits only, where the working voltage does not exceed 250 V r.m.s. The technical content is therefore identical to the base edition and its amendments and has been prepared…
