This document specifies a method for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in soil, sludge, sediment, treated biowaste,and waste using GC-MS and GC-ECD (see Table 2). The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. Under the conditions specified in this European Standard, lower limit of application from 1 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 10 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 μg/kg cannot be reached. Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCB and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. NOTE For the analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to EN 61619, EN 12766-1 and EN ISO 6468 respectively. The method can be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments.

This document specifies fire testing requirements for water mist systems used for fire protection of machinery in enclosures with volumes exceeding 260 m³.

This document specifies fire testing requirements for water mist systems used for fire protection of machinery in enclosures with volumes not exceeding 260 m³.

This European Standard specifies a manual method for the determination of the concentration of fluorinated compounds expressed in HF. Two cases are presented: - first case: the measurand is the concentration of hydrofluoric acid and gaseous and bound to particulates fluorides, - second case: the measurand is the concentration of hydrofluoric acid and gaseous fluorides. Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography. This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes. This document applies to more or less dust-laden flue gases whose HF concentration may vary between 0,1 mg/m3 and 10 mg/m3, at standard conditions of pressure and temperature. The quantification limit of the method is estimated at 0.1 mg/m3 for a sampled volume of 0.1 m3.

This European Standard specifies the performance requirements on data acquisition and handling systems (DAHS) regarding implementation of the procedures defined in EN 17255-1 including — data acquisition; — data processing; — data storage; — data output; — generation of reports; — system functions; — data security; — documentation. This European Standard supports the requirements of EN 14181 and legislation such as the IED and E-PRTR. It does not preclude the use of additional features and functions provided the minimum requirements of this European Standard are met and that these features do not adversely affect data quality, clarity or access. This European Standard does not cover additional requirements for multiplexing systems where gases are sampled from multiple sources.

This document specifies the characteristics of the Passenger Alarm System (PAS) for Urban Rail. This document covers the PAS fitted to the passenger carrying Urban Rail rolling stock and specifies: - the safety related requirements; - the functional requirements of PAS triggered by pasasengers; - the requirements for the communication channel between passengers and the driver or OCC; - the requirements for the functional behaviour of the PAS; - the requirements for the degraded modes management; - the requirements for the Passenger Alarm Device (PAD) and PAD area. This document is applicable to the categories I to III of Urban Rail rolling stock defined in CEN/CLC Guide 26: - (I) metros; - (II) trams; - (III) light rail. NOTE 1 CEN/CLC Guide 26 defines Metro, Tram and Light Rail as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic. NOTE 2 The PAS function on existing vehicles may require modification to work in conjunction with vehicles that comply with this document. NOTE 3 This European Standard covers urban rail rolling stock, both with or without a driver. NOTE 4 For rolling stock devoted to suburban passenger services, this European Standard applies when the TSIs do not apply.

This European Standard specifies a method of test for determining the reaction to fire performance of construction products excluding floorings, and excluding products which are indicated in Table 1 of EC Decision 2000/147/EC, when exposed to thermal attack by a single burning item (SBI). The calculation procedures are given in Annex A. Information on the precision of the test method is given in Annex B. The calibration procedures are given in Annexes C and D, of which C is a normative annex. NOTE This European Standard has been developed to determine the reaction to fire performance of essentially flat products. The treatment of some families of products, e.g. linear products (pipes, ducts, cables etc.), can need special rules.
