This document specifies dimensions, materials and performance requirements, including methods of test, for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure safety valves are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Pressure safety valves limit the pressure in hot water heaters. Pressure safety valves do not control the temperature and alone do not constitute the protection required for storage water heaters. They are not intended to act as expansion valves under normal conditions. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

 

ISO 23279:2017 specifies how to characterize indications from discontinuities by classifying them as originating from planar or non-planar embedded discontinuities. This procedure is also suitable for indications from discontinuities that break the surface after removal of the weld reinforcement.

 

This document specifies dimensions, materials and performance requirements (including methods of test) for expansion valves, of nominal sizes from DN 15 to DN 50, having working pressures ) from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion valves are intended for fitting to the cold potable water supply of storage water heaters, having a maximum distribution temperature of 95 °C, for all energy sources. Expansion valves do not control the temperature and alone do not constitute the protection required for storage water heaters. Expansion valves limit pressure, in the water heaters to what they are fitted, that is produced by thermal expansion of the water. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

 

This document specifies dimensions, materials and performance requirements, including methods of test, for hydraulic safety groups, of nominal sizes from DN 15 to DN 25, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Hydraulic safety groups are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Hydraulic safety groups limit the pressure in hot water heaters, prevent the backflow of water into the main circuit and prevent the discharged water to get into contact with the water in the water heater. Hydraulic safety groups do not control the temperature. They ensure the hydraulic safety of water heaters if the mechanical resistance of the water heater remains at least equal to the rating pressure. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

This European Standard describes the specifications and test methods for gravity fed devices for conditioning of drinking water that are not connected to the mains water distribution system in buildings, known as jug water filter systems. It also gives instructions for the user manuals, so that the jug water filter system can be used and maintained properly. Jug water filter systems are intended to modify the properties of drinking water only, and are not designed to make non-potable water safe for drinking. The scope of this document does not extend to combination systems that require an electrical power supply such as water heaters and water coolers systems. NOTE 1 Although jug water filter systems are covered by the widely harmonized food legislation (EU Regulations 178/2002 and 1935/2004), existing national regulations concerning the use and or the characteristics of these products remain in force NOTE 2 This standard provides no information as to whether the product is used without restriction in any of the Member States of the EU or EFTA.

 

This document specifies, dimensions, materials and performance requirements (including methods of test) for expansion groups, of nominal sizes from DN 15 to DN 25, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion groups are fitted to the cold potable water supply only for expansion purposes, e.g. of storage water heaters, having a maximum distribution temperature of 95 °C. Expansion groups limit pressure in the water heater to which they are fitted, that is produced by thermal expansion of the water, prevent the backflow of water into the supply pipe and prevent the discharged water to get into contact with the water in the water heater. Expansion groups do not control temperature and alone do not constitute the protection required for storage water heaters. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and thermal cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

This European Standard specifies a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquefied petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass). This test method quantifies soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected. WARNING - This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

 

This document specifies carriage of coded media representations which comply with visual volumetric video content which is encoded using video-based coding and video-based point cloud compression (specified in ISO/IEC 23090-5) or its derived specification.

 

This part of ISO 16200 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air by solvent desorption/gas chromatography using pumped sampling. This part of ISO 16200 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. However, activated coconut shell charcoal is frequently used. Very polar compounds may require derivatization; very low boiling compounds may only be partially retained by the sorbents and can only be estimated qualitatively. Semi-volatile compounds should be fully retained by the sorbents, but may only be partially recovered. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and by the linear dynamic range of the analytical instrumentation used. The lower limit of the useful range depends on the type of detector used, on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sorbent tubes or in the desorption solvent. Artefacts are typically sub-nanogram for activated charcoal, but higher levels of aromatic hydrocarbons have been noted in some batches. By applying this part of ISO 16200, the lower limits achieved are typically in the range of 1 µg to 100 µg of a given VOC per sample. The concentration range for which this part of ISO 16200 is valid for the measurement of airborne vapours of VOCs is dependent on the lower limit and on the volume sampled. For example, for a 10-litre sample of air, the range is approximately 0,1 mg/m3 to 100 mg/m3 individual organic compound. For a 1-litre sample of air, the range is approximately 1 mg/m3 to 1 000 mg/m3 individual organic compound, and pro rata.

 

This part of ISO 16200 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in workplace air by solvent desorption/gas chromatography using diffusive sampling. This part of ISO 16200 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of devices and sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Note 1 to entry Activated coconut shell charcoal is frequently used. Very polar compounds may require derivatization, very low boiling compounds may only be partially retained by the sorbents, polar or high boiling compounds may not be quantitatively extracted by the chosen solvent. In these cases, their concentration may be quantitatively determined, provided that reverse diffusion and analytical recovery studies are available. This part of ISO 16200 is valid for the measurement of airborne vapours of VOCs in a concentration range of approximately 0,1 mg/m3 to 1 000 mg/m3 individual organic for an exposure time of 8 h. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and, subject to dilution of the analysed solution, by the linear dynamic range of the gas chromatograph, column and detector or by the sample splitting capability of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sampling devices or in the desorption solvent. Artefacts are typically sub-nanogram for activated charcoal, but higher levels of aromatic hydrocarbons have been noted in some batches. By applying this part of ISO 16200, the lower limits of quantification achieved are typically in the range of 0,01 µg to 1 µg of a given VOC per sample. Determination of the blank value for target organic compounds is recommended for each lot of samplers.

This document specifies the test method and performance metrics to evaluate the behaviour of a vehicle equipped with door open warning system during several accidental scenarios. These potential accidents occur when a door is about to be opened and there is a risk of collision due to the vehicle door opening. This document applies to category M1 and N1 vehicles equipped with a door open warning system. NOTE Depending on accidentology, only a part of the scenarios can be used for an evaluation of performance.

 

This document specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This document has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required. A major objective of this document is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution curve. This document does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It is also realized that the chemical pre-treatments and mechanical handling stages in this document could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then this document is not used for the determination of the particle size distribution of such weakly cohesive materials.

 

This document specifies two methods for the determination of total organic carbon (TOC) in sludge, treated biowaste, soil and waste samples containing more than 0,1 % carbon in relation to the dry matter (dm). This document is validated for sludge, biowaste, soil, and waste (see also Annex A for the results of the validation).

 

Specifies a method for the determination of the total carbon content in soil after dry combustion. The organic carbon content is calculated from this content after correcting for carbonates present in the sample. If carbonates are removed beforehand, the organic carbon content is measured directly. Applicable to all types of air-dried soil samples.

 

This document specifies a method for determination of tuft withdrawal force and is applicable to all textile floor coverings with a cut and/or loop pile yarn structure.

 

This document establishes a classification system for resilient, textile, laminate and modular mechanical locked floor coverings. The classification is based on practical requirements for areas of use and intensity of use and is linked to the requirements specified in the relevant documents for each type of floor covering. This document is also intended to provide guidance for manufacturers, specifiers and consumers, to enable them to choose the appropriate class of floor covering for any given area of use or specific room. NOTE The wear and appearance of floor coverings are influenced by standards of installation and maintenance, the condition of the subfloor and the kind of use (type of footwear, high concentrations of localized traffic, etc.). These factors are intended to be taken into account when using this classification system.
