BS ISO 21723:2019 pdf free.Buildings and civil engineering works一Modular coordination一Module
This document establishes the values of basic module, multimodules for horizontal coordinating dimensions and sub-modular increments for use in modular coordination of buildings. This document also specifies preferred vertical modular dimensions, series of preferred multimodular sizes for horizontal dimensions for all types in accordance with general principles and rules for modular coordination.

ISO 6707-1, Buildings and civil engineering works一Vocabulary 一Part 1: General terms
For the purposes of this document, the terms and definitions given in ISO 6707-1 and the following apply.ISO and IEC maintain terminological databases for use in standardization at the following addresses:

vertical dimension between two modular floor planes of two consecutive floors[SOURCE: ISO 1791:1983, 25]
vertical dimension of the modular floor zone between the modular plane of the upper surface of the floor covering and the modular plane of the finished ceiling[SOURCE: ISO 1791:1983, 27, modified一”a floor covering” has been replaced with “the floor covering”]
The 15 M, 30 M and 60 M series correspond to the series in a system of preferred numbers which contain the factor five. These series can also be extended to use larger increments in the series of the multimodule 60 M such as 120 M or larger.
In the selection of sizes from Table 1, preference should be given to the series of the largest multimodule compatible with functional requirements and economic design.
The preferred multimodular sizes for horizontal dimensions are primarily intended for sizing of components, groups of components and spaces.
The series are standardized for general guidance. Functional, economical and especially national considerations may justify the use of multimodular sizes which are not included in the series.BS ISO 21723 pdf free download.
