This European Standard specifies minimum requirements for design and testing of contents gauges, which are directly connected to transportable tanks, drums, cylinders and static LPG tanks above 0,5 l water capacity excluding those used for automotive containers. This European Standard does not apply to refineries or other process plants.

This document specifies a test method for the micro-scratch resistance with two procedures (A and B) and a test method for polishing resistance (procedure C) which can be used for all types of laminate floor coverings. The resistance to polishing is related to mat surfaces.

8. ScopeThis European Standard specifies a method for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table ) in soil, sludge, sediment, treated biowaste, and waste, using GC-MS and HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see Table 2).When using fluorescence detection, acenaphthylene cannot be measured.Table —Target analytes of this European StandardTarget analyte CAS-RNaNaphthalene 91–20–3Acenaphthene 83–32–9Acenaphthylene 208–96–8Fluorene 86–73–7Anthracene 120–12–7Phenanthrene 85–01–8Fluoranthene 206–44–0Pyrene 129–00–0Benz[a]anthracene 56–55–3Chrysene 218–01–9Benzo[b]fluoranthene 205–99–2Benzo[k]fluoranthene 207–08–9Benzo[a]pyrene 50–32–8Indeno[1,2,3-cd]pyrene 193–39–5Dibenz[a,h]anthracene 53–70–3Benzo[ghi]perylene 191–24–2a CAS-RN Chemical Abstracts Service Registry Number.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 extractUnder the conditions specified in this European Standard, lower limit of application from 10 µg/kg (expressed as dry matter) for soils, sludge and biowaste to 100 µg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples (e.g. bitumen) the limit of 100 µg/kg cannot be reached. Sludge, waste and treated biowaste may differ in properties as well as in the expected contamination levels of PAH 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. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.

This document determines the guidelines and the specifications for non-destructive testing using active thermography with laser excitation.Active thermography with laser excitation is mainly applicable, but not limited to different materials (e.g. composites, metals, ceramics) and to:- the detection of surface-breaking discontinuities, particularly cracks;- the detection of discontinuities located just below the surface or below coatings with an efficiency that diminishes rapidly with a few mm depth;- the detection of disbonds and delamination parallel to the examined surface;- the measurement of thermal material properties, like thermal diffusivity;- the measurement of coating thickness.The requirements for the equipment, for the verification of the system, for the surface condition of the part to be tested, for the scanning conditions, for the recording, the processing and the interpretation of the results are specified. Acceptance criteria are not defined.Active thermography with laser excitation can be applied in industrial production as well as in maintenance and repair (vehicle parts, engine parts, power plant, aerospace, etc.).

This document specifies the safety requirements for slewing and non-slewing rough-terrain variable-reach trucks defined by ISO 5053-1 (hereafter referred to as trucks) and their integrated interchangeable work platforms having front guards that can be opened for particular operations at height (hereafter referred to as work platform).Controls can be also provided under specific circumstances at the operating position in the enclosed cab of the truck.This document deals with the significant hazards, hazardous situations and events relevant to the combination when it is used as intended and under conditions of misuse which are reasonably foreseeable. The significant hazards covered by this document are listed in Annex A.This document does not address hazards which may occur:a) when using non-integrated work platforms or other attachments not designed for lifting persons;b) when handling suspended work platforms which may swing freely;c) when operating underground or in potentially explosive atmospheres.This document does not cover trucks equipped with work platforms intended for leaving and re-entering at height.

This document provides a framework and consistent terminology for specifying user requirements. It specifies the common industry format (CIF) for a user requirement specification including the content elements and the format for stating those requirements.NOTE 1 A user requirements specification is the formal documentation of a set of user requirements, which aids in the development and evaluation of usable interactive systems.In this document, user requirements refers to:a) user-system interaction requirements for achieving intended outcomes (including requirements for system outputs and their attributes);b) use-related quality requirements that specify the quality criteria associated with the outcomes of users interacting with the interactive system and can be used as criteria for system acceptance.NOTE 2 ISO/IEC 25030 introduces the concept of quality requirements. The use-related quality requirements in this document are a particular type of quality requirement.The content elements of a user requirements specification are intended to be used as part of documentation resulting from the activities specified in ISO 9241-210, and from human centred design processes, such as those in ISO 9241-220.This document is intended to be used by requirements engineers, business analysts, product managers, product owners, and people acquiring systems from third parties.The CIF series of standards addresses usability-related information (as described in ISO 9241-11 and ISO/IEC TR 25060).NOTE 3 In addition to usability, user requirements can include other perspectives, such as human-centred quality introduced in ISO 9241-220, and other quality perspectives presented in ISO/IEC 25010, ISO/IEC TS 25011, and ISO/IEC 25030.NOTE 4 While this document was developed for interactive systems, the guidance can also be applied in other domains.This document does not prescribe any kind of method, lifecycle or process. The content elements of a user requirements specification can be used in iterative development which includes the elaboration and evolution of requirements (e.g. as in agile development).

This document specifies the safety, design, construction and performance requirements and testing for automatic shut-off valves with or without modulating control functions (hereafter referred to as ‘valves’) for burners and appliances burning one or more gaseous fuels according to EN 437:2003+A1:2009.This document is applicable to valves with declared maximum inlet pressures of more than 500 kPa (5 bar) and up to and including 6 300 kPa (63 bar).This document is applicable to- electrically operated valves and to valves actuated by fluids including the pilot valves for these fluids if actuated electrically and including release valves, but not to any external electrical devices for switching the actuating energy;- automatic shut-off valves where the flow rate is controlled by external electrical signals proportional to the applied signal.This document is not applicable to valves specifically designed for use in transmission and distribution networks.NOTE Provisions for final product inspection and testing by the manufacturer are not specified.

This document specifies the safety, construction and performance requirements for mechanical thermostats intended for use with gas appliances and similar use, hereafter referred to as ‘thermostats’.This document applies to thermostats with declared maximum inlet pressures up to and including 50 kPa (500 mbar) of nominal connection sizes up to and including DN 50 for use with one or more fuel gases in accordance with EN 437.This document applies to thermostats controlling the gas flow directly or indirectly through an integral gas valve.This document only applies to thermostats used with gas appliances which are not installed in the open air.Thermostats dealt with in this document are intended for control functions.This document is not applicable to:a) the thermocouple;b) controls which use auxiliary energy (e.g. electrical energy supplied externally);c) an assessment of the control regarding Performance Level (PL) and Safety Integrity Level (SIL).
