This document specifies requirements and gives recommendations for the design, installation, inspection and maintenance of all types of fixed land based water mist systems. This document is intended to apply to water mist automatic nozzle systems and water mist deluge systems supplied by stand alone or pumped systems. The document covers only applications and occupancies which are covered by the fire test protocols of the EN 14972 series. Aspects of water mist associated with explosion protection and/or use within vehicles are not covered by this document. This document does not cover all legislative requirements. In certain countries specific national regulations apply and take precedence over this document. Users of this document are advised to inform themselves of the applicability or non-applicability for this document by their national responsible authorities.

This document specifies the general “design for recycling” guidelines for EPS raw materials. It provides guidance on the impact of specific design characteristics on the recyclability of the product in practice and recommended design options to ensure that the product is recyclable, including target values and performance ranges, where applicable. It also provides a definition of recyclable product and of design for recycling. This document refers to the recycling processes of EPS products. The sorting and collecting steps are not part of this document. This document takes into account all currently known processes that are suitable to enable the circular economy for insulation materials. Particular attention is paid to ensuring that the most energy-efficient processes are given preference, especially mechanical recycling, unless reuse is already ruled out. For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available. At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems.

Particle sizes greater than or equal to 2 micrometres can be sized and counted by this method, but the resolution and accuracy of the results will depend upon the optical system used and the capabilities of the operator.

All hydraulic fluids with a wide range of contamination levels can be analysed according to this International Standard. However, the counting uncertainty at the larger particle sizes increases if the volume filtered is reduced to allow smaller sized particles to be counted, where a fine precipitate or a high particle concentration is present.

This document specifies the conditions for the determination of hoop tensile properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at ambient temperature in air atmospheric pressure. This document is specific to the tubular geometries since fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This document provides information on the hoop tensile properties and stress-strain response, such as hoop tensile strength, hoop tensile strain at failure and elastic constants. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. It applies primarily to ceramic and/or glass matrix composite tubes with a continuous fibrous- reinforcement: unidirectional (1D filament winding and tape lay-up), bi-directional (2D braid and weave) and tri-directional (xD, with 2 < x < 3), subjected to an internal pressure. Values expressed in this document are in accordance with the International System of Units (SI).

This document specifies a procedure to determine the consistency of a metal-saponified lubricating grease by an oscillatory rheometer. This test method is applicable for fresh as well as used lubricating greases where only small quantities of the grease are present and the usually used worked penetration cannot be determined due to the small quantity. The determined calibration is only valid for metal-saponified lubricating greases like lithium, lithium calcium and also lithium- and calcium complex. The method described in this document is applicable for lubricating greases with NLGI grades 00, 0, 1, 2 and 3 in accordance with ISO 6743-99. For greases of other NLGI grades no precision was determined.

This document specifies the general requirements for the preparation of samples and initial suspensions prior to microbiological examinations of soil improvers and growing media.

This method might not be appropriate in every detail for certain products. In this case, different methods which are specific to these products can be used if necessary, for justified technical reasons.
