Central safety power supply systems

This document specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This standard covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source. Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and may be suitable for energizing other essential safety equipment, for example: – electric circuits of automatic fire extinguishing installations; – paging systems and signalling safety installations; – smoke extraction equipment; – carbon monoxide warning systems; – special safety installations related to specific buildings, e.g. high-risk areas. The power supply of CPS systems should be dedicated only to the essential safety equipment, and not for other type of loads such as general purpose IT or industrial systems etc. Combinations of the aforementioned safety equipment types are permitted together on the same central safety power supply system providing the availability for safety equipment loads is not impaired. A fault occurring in a circuit should not cause the interruption in any other circuit used to supply essential safety equipment. Schematic representations of typical central safety power supply equipment are depicted in Clause 4. Power supply systems for fire alarm equipment that are covered by EN 54 (series) are excluded.

Workplace exposure - Size fraction definitions for measurement of airborne particles

This document specifies sampling conventions for airborne particle size fractions to assess health-related exposure resulting from the inhalation of particles in workplace atmospheres. Conventions are defined for the inhalable, thoracic and respirable fractions. The sampling conventions only describe the inhalation of particles and their penetration in the respiratory tract as governed by inertia (impaction). Exhaled particles and deposition in the respiratory tract by other mechanisms, e.g. diffusion, are not considered in this document. The sampling conventions defined in this document apply to both indoor and outdoor workplaces. The conventions assume particles penetration and only oral breathing as a worst-case scenario. Nevertheless, the conventions are applicable to both oral and nasal breathing. The conventions are defined based on assumptions given in Clause 6. The choice of convention for a specific application depends on the region of the respiratory tract affected by the health impact of the particle component of interest (see Clause 5). The conventions can be applied to various metrics, including particle number, length, surface area, volume, or mass, depending on the type of particle analysis performed on the sampled aerosol fraction. The health-related fraction concentrations defined in this document are often expressed as the mass of sampled particles per volume of sampled air to allow comparison with mass-based occupational exposure limit values. The conventions primarily apply to the aforementioned metrics, however, they are not applicable to situations involving limit values expressed in a different metric, such as fibre limit values defined by length, diameter, and aspect ratio, unless a measurement procedure explicitly specifies sampling a particular health-related size fraction [11]. The primary objective of this document is to establish standardized conventions for health-related particle size fractions. Sampling is generally carried out using dedicated samplers, for which there is no need to measure the aerodynamic size distribution of the airborne particles to be sampled. Samplers separating airborne particles into one or more relevant fractions are currently available. In general, no assumptions or pre-knowledge are needed on the number of modes, modal diameter(s) or width of the particle aerodynamic size distribution of the airborne particles to be sampled. The conventions in this document are intended to be used for the determination of the exposure of an average worker based on average penetration curves. This document is not intended to determine the deposited dose of an individual worker. The conventions are primarily intended for assessing workers’ exposure to airborne particles by sampling the airborne particles. This document does not apply to large particles emitted at high speed that travel due to their initial momentum, instead of being carried by the air (airborne) and aspirated into humans’ respiratory tract and aerosol samplers by suction (see Annex B). All wind speeds referenced throughout this document are based on the relative speed between the worker and the surrounding air.

Mechanical vibration - Testing of mobile machinery in order to determine the vibration emission value

This document specifies the determination of whole-body and hand-arm vibration emissions at operator position(s) during testing of mobile machinery. The purpose of this document is to assist technical standardization committees responsible for specific types of machinery in preparing vibration test codes to ensure that such vibration test codes — are as homogeneous as possible with each individual test code having the same basic structure, — are in full accordance with basic standards on measurement of vibration emission, — reflect the latest technical knowledge of methods of determining the vibration emission from the specific family of machinery under consideration, — provide manufacturers with a standardized method for the determination and declaration of the vibration emission value(s) of their machinery, — enable the user of the machinery or the member of an inspection body to compare the vibration emission values of different machinery and to verify the vibration emission values provided by the manufacturer. This document provides requirements for the preparation of vibration test codes (C-type standards), including guidelines for the conditions under which the measurements shall be made (e.g. operating conditions). Information to be included in a typical vibration test code is summarized in Annex A. This document applies to sitting and standing positions. It is applicable to all mobile machinery producing periodic or random vibration with or without transients. This document contains sufficient guidance for designing an appropriate test for machinery for which no vibration test codes exist. It can also be used for the determination of vibration emission values of individual machines. This document is not applicable to rotational vibration and backrest vibration. This document does not present limits or recommended vibration values.

Granular waste materials, sludges, soil, soil-like materials and sediments - Leaching - Compliance test for leaching - Part 1: One-stage batch test at a liquid-to-solid ratio of 2 L/kg for materials with particle size below 4 mm (without or with size reduction)

This document in the series specifies a compliance test providing information on leaching of granular waste materials, sludges, soil, soil-like materials and sediments under the experimental conditions specified hereafter, and particularly a liquid to solid ratio of 2 L/kg dry matter. It applies to materials which have a particle size below 4 mm without or with size reduction. This document has been developed to investigate the leaching of inorganic and non-volatile organic substances from granular waste materials, sludges, soil, soil-like materials and sediments. It does not take into account the consequences of microbiological processes in organic degradable materials. The test procedure specified in this document produces an eluate which is subsequently characterized physically and chemically according to appropriate standard methods. This document includes two different procedures for eluate preparation prior to analysis, one procedure for non-volatile organic substances, inorganic substances and DOC and one for inorganic substances and DOC. When assessing only the leaching of inorganic substances and DOC, certain precautions are needed when assessing the leaching of organic substances can in some cases be omitted. This procedure cannot be applied to materials with a water content or such a water affinity that a good mixing of the solid with the predetermined quantity of liquid is not achievable. This procedure does not apply to materials reacting with the leachant, leading, for example, to excessive gas emission, a solidifying effect or an excessive heat release. In that case, the material can be wetted prior to carrying out the leaching test. This test cannot be used alone to determine the leaching behaviour of granular waste materials, sludges, soil, soil-like materials and sediments, as specified in EN 12920. This document does not address issues related to health and safety.

Eurocode 1 - Actions on structures - Part 4: Silos and tanks

1.1 Scope of EN 1991-4 (1) This document provides rules for calculating actions for the structural design of silos and tanks. NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids. NOTE 2 For limitations on rules for silos given in this document, see 1.3. NOTE 3 For limitations on rules for tanks given in this document, see 1.4. (2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them. NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data. (3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures. NOTE FRP is the standard acronym for fibre reinforced polymer materials. (4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project. NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos. NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks. 1.2 Assumptions (1) The assumptions of EN 1990-1 apply. (2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks. 1.3 Limitations on silos 1.3.1 Geometrical limitations (1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document: - the silo planform cross-section shapes are limited to those shown in Figure 1.1c. NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7. NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c; - the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1): hc/dc < 10 (1.1) hb < 100 m (1.2) dc < 60 m (1.3) NOTE 3 See Figure 1.1 for hc, dc and hb. - the structural transition lies in a single horizontal plane (see Figure 1.1a). [Figure 1.1 - Silo forms showing dimensions and pressure notation] (2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b ≤ 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations. (3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document. (4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped. 1.3.2 Limitations on the stored particulate solids (1) The following limitations on the stored particulate solids apply to the design rules for silos contained in this document: ...
