This part of ISO/IEC 80079 specifies the technical requirements for design, construction, conversion, testing, marking and the information required for use to avoid or minimise the possibility of ignition which could from reciprocating internal combustion engine intended for use in explosive atmospheres including: – Group I EPL Mb for use in underground workings susceptible to firedamp or combustible dust, – Group II EPL Gb and EPL Gc for use in explosive atmospheres of flammable gas and vapour, and – Group III EPL Db and EPL Dc for use in explosive atmospheres of combustible dust. – For EPL Gc and Dc engines, only normal operating conditions need to be taken into account. Malfunctions need not be considered (see B.2.1). This document includes those tests of the engine and its ancillary devices that are required to verify compliance with this document. This document applies to both reciprocating internal combustion engines with compression ignition for EPL Mb, Gb, Gc, Db, Dc and gaseous fuelled spark ignition engines for EPL Gc. See Annex G. This document does not define requirements relating to the driven machinery and equipment. This document does not apply to – explosive mixtures of vapours and gases, which tend to self-decompose (for example carbon disulphide (CS2), ethylene oxide (C2H4O), acetylene (C2H2)) or which are chemically unstable; • hydrogen fueled engines, including blends; • engines used in areas for the processing, manufacture or storage of explosives; • gasoline and other spark ignited engines where the fuel is injected into the combustion chamber as a liquid; or • electrical ignition spark systems. Note 1 Spark ignition systems used with equipment covered by ISO/IEC 80079-41 is covered by IEC 60079-45 This document solely deals with explosion protection requirements. Requirements on gaseous or particulate exhaust emissions are not covered by this standard. General safety requirements are not included in this International Standard. This document does not specify requirements for safety, other than those directly related to the possibility of ignition of flammable mixtures in the surrounding atmosphere which can lead to an explosion. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it can be assumed that the engine may be operated are: • temperature –20 °C to +60 °C • pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and • air with normal oxygen content, typically 21% v/v. An engine for use outside of the standard atmospheric conditions is to be designed, constructed tested and marked for those conditions. The ignition hazard assessment, ignition, protection provided, additional testing (if necessary) manufacturer’s technical documentation and instructions to the user are intended toclearly demonstrate the engine’s suitability for the conditions. NOTE 2 changes in temperature and pressure have an influence on the characteristics of the explosive atmosphere including ignitability NOTE 3 IEC TS 60079-43 gives information for equipment used in explosive atmospheres in environmental conditions which include ambient temperatures below –20 °C and additional adverse conditions, including maritime applications. NOTE 4 Reciprocating internal combustion engines are not considered as pressure vessels. This document supplements and modifies the general requirements of IEC 60079-0:2017 and ISO 80079-36. Where a requirement of this document conflicts with a requirement of IEC 60079-0:2017 and ISO 80079-36 as far as applicable for Ex engines, the requirement of this standard takes precedence. NOTE 5 On-going inspection, maintenance and repair aspects play an important role in control of hazardous area installations and the user’s attention is drawn to IEC 60079-17, IEC 60079-19 and IEC 60079-14 and manufacturer’s instructions for further information concerning these aspects.

This document specifies a method for the enumeration of culturable microorganisms in water by counting the colonies on a low-nutrient agar culture medium after incubation at 22 °C for 7 d. The method is intended to measure the operational efficiency of the treatment process of public drinking water supplies, including the water in distribution systems and containers. The method is particularly suitable to monitor water for human consumption which is low in nutrients and is distributed in temperatures below 20 °C. The method can be applied to all types of water, including pool and spa waters. NOTE 1 The low-nutrient agar in use in this document usually gives higher colony counts from water samples than nutrient-rich formulations of culture media typically used for enumeration of culturable microorganisms. NOTE 2 The method is also applicable for waters of very low nutrient content such as de-ionised, distilled or reverse osmosis waters. NOTE 3 This document describes the use of R2A medium. There are other formulations available, e.g. R3A medium that might be suitable for certain applications but go beyond the scope of this document.

 

This European Standard specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-immiscible liquids. Requirements are also given for marking. WARNING - Any type approval according to this standard is invalidated by any change in composition of the approved product. Some concentrates conforming to this part of EN 1568 can also conform to other parts and therefore can also be suitable for application as medium and/or high expansion foams, and for application at low expansion to water-miscible liquids.

This document gives guidelines for the restoration of rivers, including their channels, riparian zones and floodplains. The word ‘river’ is used as a generic term to describe permanently flowing and intermittent watercourses of all sizes, with the exception of artificial water bodies such as canals. Some aspects of landscape restoration beyond the boundaries of what are often considered typical river processes are also considered. A clear framework of guiding principles to help inform the planning and implementation of river restoration work is provided. These principles are applicable to individuals and organizations wishing to restore rivers, and stress the importance of monitoring and appraisal. This document makes reference to existing techniques and guidance, where these are appropriate and within the scope of this document. This document gives guidelines on: - the core principles of restoration; - aims and overall outcomes of river restoration; - the spectrum of typical approaches to river restoration with a focus on those that are nature-based and restore both physical and ecological aspects; - identifying opportunities for restoration and possible constraints, with a focus on physical and natural rather than socio-economic aspects; - different scales of restoration and how restoration works across different catchments and landscapes; - the importance of monitoring and appraising restoration work across the range of approaches and scales.

This document provides requirements and recommendations on user assistance, their nature, use and guidance on how to use them. This document is concerned with software components of interactive systems to make human-system interaction usable as far as the most basic interaction aspects are concerned. This document provides a list of generic user assistance guidelines regardless of a specific visualization and implementation technology. It gives guidance and recommendations on selection, usage and dependencies of user assistance and their applications in various contexts. It does not provide detailed coverage of the methods and techniques required for design and implementing of user assistance. The information in this document is intended for use by those responsible for developing user interfaces, but also for planning and managing platform specific aspects of user interface design. It therefore addresses technical issues only to the extent necessary to allow such individuals to understand the relevance and importance of a consistent interaction technique use in the design process. It also provides a framework for human factors and usability professionals involved in human-centred design. Detailed human factors, ergonomics, usability, and accessibility issues are dealt with more fully in a number of standards including other parts of ISO 9241 which sets out the broad principles of ergonomics (see Bibliography). Annex A provides a checklist that can be used to support claims of conformance to this standard.
