Bases for design of structures — Determination of snow loads on roofs

Bases du calcul des constructions — Détermination de la charge de neige sur les toitures

ISO 4355:2013 specifies methods for the determination of snow load on roofs.

It can serve as a basis for the development of national codes for the determination of snow load on roofs.

National codes should supply statistical data of the snow load on ground in the form of zone maps, tables, or formulae.

The shape coefficients presented in ISO 4355:2013 are prepared for design application, and can thus be directly adopted for use in national codes, unless justification for other values is available.

For determining the snow loads on roofs of unusual shapes or shapes not covered by ISO 4355:2013 or in national standards, it is advised that special studies be undertaken. These can include testing of scale models in a wind tunnel or water flume, especially equipped for reproducing accumulation phenomena, and should include methods of accounting for the local meteorological statistics. Examples of numerical methods, scale model studies, and accompanying statistical analysis methods are described in ISO 4355:2013 (Annex G).

The annexes of ISO 4355:2013 describing methods for determining the characteristic snow load on the ground, exposure coefficient, thermal coefficient, and loads on snow fences are for information only as a consequence of the limited amount of documentation and available scientific results.

In some regions, single winters with unusual weather conditions can cause severe load conditions not taken into account by ISO 4355:2013.

Determination of the characteristic limits (decision threshold, detection limit and limits of the coverage interval) for measurements of ionizing radiation — Fundamentals and application — Part 4: Guidelines to applications

Détermination des limites caractéristiques (seuil de décision, limite de détection et limites de l'intervalle élargi) pour le mesurage des rayonnements ionisants — Principes fondamentaux et applications — Partie 4: Lignes directrices relatives aux applications

This document specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the “decision threshold”, the “detection limit” and the “limits of the coverage interval” for a non‑negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. In particular, the measurand can be the net count rate as the difference of the gross count rate and the background count rate, or the net activity of a sample. It can also be influenced by calibration of the measuring system, by sample treatment and by other factors.

ISO 11929 has been divided into four parts covering elementary applications in ISO 11929-1, advanced applications on the basis of the ISO/IEC Guide 98-3:2008/Suppl.1 in ISO 11929-2, applications to unfolding methods in ISO 11929-3, and guidance to the application in ISO 11929-4.

ISO 11929-1 covers basic applications of counting measurements frequently used in the field of ionizing radiation metrology. It is restricted to applications for which the uncertainties can be evaluated on the basis of the ISO/IEC Guide 98-3 (JCGM 2008). In ISO 11929-1:2019, Annex A the special case of repeated counting measurements with random influences and in ISO 11929-1:2019, Annex B, measurements with linear analogous ratemeters are covered.

ISO 11929-2 extends ISO 11929-1 to the evaluation of measurement uncertainties according to the ISO/IEC Guide 98-3:2008/Suppl.1. ISO 11929-2 also presents some explanatory notes regarding general aspects of counting measurements and Bayesian statistics in measurements.

ISO 11929-3 deals with the evaluation of measurements using unfolding methods and counting spectrometric multi-channel measurements if evaluated by unfolding methods, in particular, alpha- and gamma-spectrometric measurements. Further, it provides some advice how to deal with correlations and covariances.

ISO 11929-4 gives guidance to the application of ISO 11929 (all parts), summarizing shortly the general procedure and then presenting a wide range of numerical examples. The examples cover elementary applications according to ISO 11929-1 and ISO 11929-2.

The ISO 11929 (all parts) also applies analogously to other measurements of any kind if a similar model of the evaluation is involved. Further practical examples can be found in other International Standards, for example, see References [1 to 20].

NOTE       A code system, named UncertRadio, is available allowing for calculations according to ISO 11929-1 to ISO 11929-3. UncertRadio[40][41] can be downloaded for free from https://www.thuenen.de/en/fi/fields-of-activity/marine-environment/coordination-centre-of-radioactivity/uncertradio/. The download contains a setup installation file that copies all files and folders into a folder specified by the user. After installation one has to add information to the PATH of Windows as indicated by a pop‑up window during installation. English language can be chosen and extensive “help” information is available. Another tool is the package ‘metRology’[44] which is available for programming in R. It contains the two R functions ‘uncert’ and ‘uncertMC’ which perform the GUM-conform uncertainty propagation, either analytically or by the Monte Carlo method, respectively. Covariances/correlations of input quantities are included. Applying these two functions within iterations for decision threshold and the detection limit calculations simplifies the programming effort significantly. It is also possible to implement this document in a spreadsheet containing a Monte Carlo add-in or into other commercial mathematics software.

Information technology — Learning, education, and training (LET) – Access for All (AfA) cognition accessibility core properties

This standard is for people with cognitive and learning disabilities who make or use digital resources.
This includes, but is not limited to: cognitive disabilities, learning disabilities, neurodiversity, or intellectual disabilities.
The standard specifies a common, interoperable set of extensible properties for the description of resource content and potential users’ comprehension needs and preferences, to enable network supported individualization of resources, services and environments to match the unique needs and
preferences of the individual.
In particular, it defines properties for description of characteristics of content and representations that
affect a person’s ability to comprehend the resource in whatever form (sound, image, text, touch, smell)
they encounter it. The standard conforms to ISO 19788 and thus includes all relevant mechanisms for
the publication of terminology for such descriptions, including publicly available registries of terms and
related metadata resources such as application profiles.
The properties do not describe the form of the resource as distinct from its intellectual content but can
include a description of the form that may affect content comprehension. Other standards provide
terms for descriptions of sensory and other characteristics of resources (see for example, AfA Core
Terms, ISO/IEC 4932 in development).
The AfA Cognition terms may also be used to indicate a user’s accessibility needs and preferences for
resources. Thus, they may enable resources to be matched to a user’s unique needs and preferences.
A set of core AfA Cognition terms can be used in a Digital Resource Description and equally in a
Personal Needs and Preferences profile.
This standard takes an inclusive approach to individualization, since any user can experience a
mismatch of their individual accessibility needs and preferences and the content or services delivered;
it is not restricted to descriptions related to stereotypical medical notions of disability.
This standard aims to maximize conformance of AfA terms with the ISO/IEC 19788 series, Metadata
for Learning Resources, and therefore the W3C Resource Description Framework (see https://www.w3.
org/RDF/).


Information technology — Learning, education and training Access for All (AfA) Adaptation terms

This standard specifies a common, interoperable set of extensible properties for the description of relationships between resources, particularly resources (including resource components) that are adapted for increased accessibility to a particular user.
The standard includes using all relevant mechanisms for the publication of terminology for such descriptions, including publicly available registries of terms and related metadata resources such as application profiles. The property specifications are conforment to ISO/IEC 19788-1 Metadata for Learning Resources, and therefore also the W3C Resource Description Framework (https://www.w3.org/RDF/).
ISO/IEC 4932 defines a set of AfA terms that can be used in a Digital Resource Description or a Personal Needs and Preferences profile. These constitute application profiles and conform to ISO/IEC 19788-1.
