This document describes the method for determining the contribution of cement’s alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack.
The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blast furnace slag, or limestone) [1].
This test method can be used in the framework of preventing the risk of alkali silica reaction [2].

This document specifies the equipment to be used, the procedures to be applied and the requirements for sampling common cement and/or its constituent materials, representative of defined lots, for testing purposes.
The same equipment and procedures can be used for other types of cement or materials; in some cases, modifications to the procedure are also permitted, provided that this document and/or the modifications are referenced in the relevant product standards.
The provisions of this document are only applicable when samples of constituent of common cement are:
a) required for evaluating the conformity of common cement or constituent of cement at the characteristics related to common cement, to cement constituents, to the release of dangerous substances to soil and ground water of common cement, and to environmental sustainability of common cement; or
b) requested for checking a delivery or a lot with a standard, the provisions of a contract or the specification in an order.
This document is applicable to the sampling of powders or bulk materials, whether they are:
c) contained in silos;
d) contained in bags, canisters, drums or any other packages;
e) transported in bulk in road vehicles, railway wagons, ships, etc.
NOTE The requirements of this document can also, by agreement between the parties, be followed for acceptance inspections for all non-standardized hydraulic binders.

This document specifies general requirements for detection of human pathogenic viruses in bioaerosols in workplace atmospheres (Annex A and Annex B), including sampling strategy, sample transportation and processing and methods of laboratory analysis.

This document is applicable to efficient particulate air filters (EPA), high efficiency particulate air filters (HEPA) and ultra-low penetration air filters (ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry.
This document establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency.
This document is based on particle counting methods which actually cover most needs of different applications.

This document specifies minimum performance requirements, test methods, classification as well as marking for respiratory infection prevention devices (RIPDs).
RIPDs are intended to reduce the emission of infective agents from the user’s airways into the environment and also reduce exposure to the user from inhalation of infective agents.
RIPDs are intended for use by the general population.

This document describes a test method for the determination of the water content of samples of bituminous mixtures. The test method is suitable for checking conformity to a product specification, where required.
Exposure levels are related to both handling procedures and ventilation provision and it is emphasized that adequate training should be given to staff employed in the usage of these substances.

This document establishes the basis for testing and classifying free-standing safes, safe plinths, built-in safes (floor and wall), ATM safes and ATM bases, strongroom doors and strongrooms (with or without a door) according to their burglary resistance.
This document does not cover testing and classifying Deposit Systems and ATM systems.

This document establishes a common basis for planning and design, area and space management, financial assessment, as well as a tool for benchmarking in the life cycle of the built asset. This document covers area and space measurement for existing owned or leased buildings as well as buildings in state of planning or development.
This document establishes a framework to deal with area and space measurement to promote both the entire life cycle information requirements and the digital technologies used by the industry. In addition, it defines clear terms and definitions as well as methods for measuring horizontal areas and volumes in buildings and/or parts of buildings, independent of their function.

This document applies to hot rolled and cold rolled non-coated steel flat products made of multiphase steels for cold forming. It covers cold rolled products of thicknesses t ; < 3 mm and hot rolled products of thicknesses t ≤ 6,5 mm.
These products are delivered in sheet, hot rolled strip, slit hot rolled strip, cold strip, slit cold rolled strip or cut lengths obtained from slit wide strip.
Flat products of multiphase steels for cold forming can be delivered with an electrolytic zinc coating according to EN 10152.

This document provides guidance to support information sharing on circular economy aspects throughout value networks by providing product-group agnostic data entries in a common data dictionary. 

This document provides a framework to guide organizations of all types and sizes.

This document complements content-related aspects addressed in other standards or applications for data or information sharing through a digital product passport (DPP)and does not overlap with the DPP framework and system developed by CEN/CLC/JTC 24. 

This document is intended to help to set a framework for how to support information sharing on circular economy aspects throughout value networks but is not foreseen to be used for conformity assessment with regulations.

This document specifies the requirements for manual sampling of oilseeds by manual means or by automated mechanical means, for the purpose of assessing their quality and condition.
Note An exemple of "condition" is an odour due to a treatment product.
Stockpiles are excluded of the scope of this document.

This document specifies minimum requirements for instruments and systems that fall into the class of corneal topographers (CTs). It also specifies tests and procedures to verify that a system or instrument complies with this document and thus qualifies as a CT according to this document. It also specifies tests and procedures that allow the verification of capabilities of systems that are beyond the minimum requirements for CTs.
This document defines terms that are specific to the characterization of the corneal shape so that they may be standardized throughout the field of vision care.
This document is applicable to instruments, systems and methods that are intended to measure the surface shape of the cornea of the human eye.
NOTE      The measurements can be of the curvature of the surface in local areas, three-dimensional topographical measurements of the surface or other more global parameters used to characterize the surface.
This document is not applicable to ophthalmic instruments classified as ophthalmometers.

This document outlines the conceptual framework and methodology for linking abstract concepts between BIM and GIS standards to facilitate BIM/GIS interoperability. 

This document provides the mechanisms to establish links between abstract concepts in both domains in terms of metamodels, abstract conceptual schemas and application schemas.

This document specifies the characteristics of single-pole circuit breakers, temperature compensated with a rated current from 20 A to 25 A, used in aircraft on-board circuits at a temperature between −55 °C and 125 °C and at an altitude of 15 000 m max.
These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action “trip-free” tripping.
They will continue to function up to the short-circuit current.

This document specifies a method for measuring the cross-talk of a cable or between cables.
