This document contains terms and definitions for CBRNE (chemical, biological, radiological, nuclear, explosive) applications. Common understanding and communication is important in the implementation of an effective CBRNE response and this communication will be most effective if there is common understanding of the terms used. Many of the terms and definitions listed here have been widely used for many years, while others are the result of cross-cutting experience of areas of CBRNE. The gradual evolution of our understanding of CBRNE and response measures means that CBRNE terminology will continue to develop. This document is dedicated to first responders, administrative staff, industry representatives and researchers.

This document specifies the testing methodology to be used for glass products that are claiming fire resistance. The methodology covers Type Testing as defined in the relevant glass product standard. NOTE This document provides guidance with the declaration of the characteristic, Safety in case of fire − Resistance to fire (for glass for use in a glazed assembly intended specifically for fire resistance) for the CE marking. The same methodology can also be used to determine the performance classification for market applications (see Annex B). The methodology covers all glass product types that may require testing and classification for fire resistance. Fire resistance testing covers end use applications for example: - doors; - partitions, walls (including curtain walling); - floors, roofs; - ceilings.

This document specifies a method for the sampling and analysis of NH3 in ambient air using diffusive sampling. It can be used for NH3 measurements at ambient levels, but the concentration range and exposure time are sampler dependent, and the end user is therefore advised to comply with the operating instructions provided by the manufacturer. NOTE Denuders may be used as a surrogate reference method until there are improvements in the continuous optical methods.

The purpose of this document is to allow users to evaluate bulk materials with regard to the amount of fine fraction of potentially hazardous substances, especially crystalline silica. This Part 1 describes the requirements and choice of test method. It provides the user with guidance on how to select the method as well as the preparation of the sample and determination of crystalline silica by XRD and FTIR. This document is applicable for bulk materials that contain particles in the size range from 0,1 μm to 125 μm satisfying with the criteria given in Part 2 and Part 3 of this document series. The current industrial minerals within the scope of this method are: quartz, clay, kaolin, talc, feldspar, mica, cristobalite, vermiculite, diatomaceous earth, barite and andalusite. The method may be applicable to other bulk materials, following full investigation and validation.

The purpose of this document is to allow users to determine a sizeweighted fine fraction by the sedimentation method. The method in this part uses a liquid sedimentation technique to separate the fine fraction, which is then analysed for its substance of interest, e.g. crystalline silica. Informative annexes within this document describe specific methods for the evaluation of FF for specific bulk materials. This document is applicable for bulk materials that contain particles in the size range from 0,1 μm to 125 μm satisfying with the criteria given in this part and Part 3 of the document series. The current industrial minerals within the scope of this method are: quartz, clay, kaolin, talc, feldspar, mica, cristobalite, vermiculite, diatomaceous earth, barite and andalusite. The method may be applicable to other bulk materials, following full investigation and validation.

The purpose of this document is to allow users to determine the fine fraction with the calculation method. It also describes the assumptions and preconditions to be met in order for this method to be valid. This calculation method is applicable only after experiments have shown that the results are accurate and consistently equal or higher than the results from sedimentation, as described in Part 2, for that particular bulk material. For preparation of the sample and determination of crystalline silica by XRD and FTIR the users can refer to Part 1. An informative annex describes a specific method for the evaluation of the FF recommended for diatomaceous earth bulk materials. Due to the internal porosity of diatomaceous earth, the general instructions given in this part of the standard are adapted in order to take into account the material’s effective density. This document is applicable for bulk materials that contain particles in the size range from 0,1 μm to 125 μm satisfying with the criteria given in this part and Part 2. The current industrial minerals within the scope of this method are: quartz, clay, kaolin, talc, feldspar, mica, cristobalite, vermiculite, diatomaceous earth, barite and andalusite. The method may be applicable to other bulk materials, following full investigation and validation.

This document describes the basic requirements for the design and application of explosion suppression systems. This document also specifies test methods for evaluating the effectiveness and the scale up of explosion suppression systems against defined explosions. This document covers: — general requirements for explosion suppression system components; — evaluating the effectiveness of an explosion suppression system; — evaluating the scale up of an explosion suppression system; — development and evaluation of design tools for explosion suppression systems; — installation, operation and maintenance instructions for an explosion suppression system. This document is applicable only to explosion suppression systems intended for the protection of closed, or essentially closed, enclosures in which an explosion could result as a consequence of ignition of an explosible mixture, e.g. dust-air, gas(vapour)-air, dust-gas(vapour)-air and mist-air. This document is not applicable for explosions of materials listed below, or for mixtures containing some of those materials: — unstable materials that are liable to dissociate; — explosive materials; — pyrotechnic materials; — pyrophoric materials.

This document contains specifications for active sampling of bioaerosols from exhaust air flowing through a defined cross-section of a stack. It defines general principles that have to be taken into account during an isokinetic sampling campaign for bioaerosols by bubbling the exhaust air through a specific impinge designed for emission measurements. In this document the application with culturable organisms is specified but the same principle might be applicable for non-cultural based methods (e.g. molecular and/or enzyme-based methods). The impinger is designed to allow a sample volume flow of 1 m3/h to 1,8 m3/h, or 16 l/min to 30 l/min, respectively, and has been tested with regard to various microorganisms within broad concentration ranges [1; 2; 3; 4]
