This document specifies the quality assurance and quality control procedures related to automated dust arrestment plant monitors. This document applies to two types of instruments commonly used for dust arrestment plant control purposes: — filter dust monitors that are configured in mass concentration units (e.g. mg/m3) and is used for dust arrestment control purposes; — filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of the dust pulses created by the cleaning process of the dust arrestment plant. This document applies to instruments certified according to the requirements of EN 15859. This document provides information on the configuration, ongoing quality assurance (with internal zero and reference checks) and annual surveillance tests of instruments. This ensures that the instrument is providing information to demonstrate that dust arrestment plant is working correctly and controlling dust pollution to the required levels. The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with the standard reference method according to EN 13284-1. This document specifies the set-up of filter leakage monitors used to monitor a change in response caused by deterioration in the operation of the dust arrestment plant.

" This European Standard specifies the characteristics and the performance requirements of the Passenger Alarm System (PAS). The aim of the Passenger Alarm System is to: - allow passengers, in case of emergency situations, to inform the driver; -allow the driver to keep the train moving or to stop the train at a safe location; - stop the train automatically: a) at a platform, b) if there is no acknowledgement by the driver. This European Standard covers the PAS fitted to the passenger carrying rolling stock and specifies: - the functional requirements for an alarm triggered in the driving cab (Clause 6); - the communication channel between the driver and passengers or on-board staff (6.4) - the dynamic analysis of the PAS (Clause 7); - the requirements for the degraded modes management (Clause 8); - the safety related requirements (Clause 9); - requirements for the Passenger Alarm Device (PAD) and PAD area (Clause 10). This European Standard applies to mainline rolling stock, which is in the field of the EU Directive 2008/57/EC. This standard does not apply to metros, trams and light rail, as defined by the CEN/CENELEC Guide 26. Existing Passenger Alarm Systems may require modification to work in conjunction with vehicles that comply with this standard. NOTE 1 Most of the requirements of UIC 541-6 are compliant with this standard. Other communications systems such as "communication device for passengers", "call for aid", "emergency call" or "call for assistance" are covered by EN 16683."

This European Standard specifies design principles and performance requirements for tertiary clarification (receiving effluent from secondary treatment) by physical filtration plant at wastewater treatment plants serving more than 50 PT. NOTE 1 Ultrafiltration, nanofiltration and reverse osmosis are not covered within the scope of this standard as they are not considered to be used for tertiary clarification. NOTE 2 Soil filtration is not covered in this standard. NOTE 3 Activated carbon filtration is excluded from the scope of this standard as it is not considered to be a form of mechanical filtration.

This document specifies requirements for the design and construction of metallic gravity-discharge tanks intended for the carriage of substances having a vapour pressure not exceeding 110 kPa (1,1 bar) (absolute pressure) at 50 °C. NOTE 1 Gravity discharge tanks have no maximum working pressure. However, during operation, pressure in the shell may occur, for example due to flow restrictions in vapour recovery systems or opening pressures of breather devices. It is important that these operating pressures do not exceed the test pressure of the tank or 0,5 bar, whichever is the highest. This document specifies requirements for openings, closures, pipework, mountings for service equipment and structural equipment. NOTE 2 This document does not specify requirements for items of service equipment other than pipework. This document is applicable to aircraft refuelers that are used on public roads. It is also applicable to inter-modal tanks (e.g. tank containers and tank swap bodies) for the transport of dangerous goods by road and rail. NOTE 3 This document is not applicable to fixed rail tank wagons.

This document specifies the evaluation of the fire performance of water mist systems for offices, schools class rooms and hotels. This document test protocol is applicable to ceiling mounted automatic nozzles to be used in unlimited volume. This document is applicable for horizontal, solid, flat ceilings with heights of 2 m and above, up to the maximum ceiling height tested.

This European Standard specifies a horizontal reference method for the determination of emissions of regulated dangerous substances from construction products into indoor air. This method is applicable to ammonia. It is based on the use of a test chamber and subsequent analysis of ammonia by spectrophotometry, ion chromatography, ammonia specific electrode or photo acoustic monitoring. NOTE The standard is amending EN 16516:2017.

1.1 This document defines requirements and tests which apply to: - collecting heads with a nominal pressure of 16 bar (1,6 MPa) PN16 which are used by fire and rescue services to combine two or more inlets into one or more outlets; - dividing breechings with a nominal pressure of 16 bar (1,6 MPa) PN 16 which are used by fire and rescue services to divide one or more inlets into two or more outlets. NOTE 1 In this document "ColDiv" is used to refer both to collecting heads and dividing breechings. NOTE 2 In this document, drawings of collecting heads and dividing breechings are shown inlets downwards and outlet upwards. 1.2 This document is not applicable to collecting heads or dividing breechings which have been manufactured before its date of publication as a European Standard.
