This document specifies a method for tensile testing of test pieces of foil and strip of metals with a nominal thickness less than 0,200 mm by using computer-controlled testing machines. The used test pieces according to this document are rectangular (parallel sided strips) and are prepared by cutting. This method is used to determine typically the proof strength, Rp0,2, the tensile strength, Rm, the percentage plastic extension at fracture, Ax mm, (using the automatic determination by the machine) or the (plastic) elongation after fracture, Ax mm, (by manual determination). NOTE 1 The use of a computer-controlled tensile testing machine is important to apply parameters and fulfil several procedures. NOTE 2 EN ISO 6892 1:2019 Annex B specifies test pieces (shape, dimensions, preparation, determination of the original cross-sectional area) for thin products flats between 0,1 mm and 3 mm thickness. EN ISO 6892 1:2019 Clause B.1 specifies requirements for products of less than 0,5 mm thickness, which can require special precautions. NOTE 3 This document and EN ISO 6892 1:2019 Annex B both apply to products of thickness between 0,1 mm and 0,2 mm. For further information, see Clause 5.

 

This document specifies requirements and a test method to assess the resistance to ignition by a smouldering cigarette equivalent of integrated or non-integrated components of a wheelchair intended to protect tissue integrity and/or provide postural support. The electrical ignition source is also a simulation of other potential sources of environmental ignition hazards. The tests measure only the resistance to ignition of the items tested, and not the ignitability of the complete wheelchair. It gives an indication, but cannot guarantee, of the ignition behaviour of the assembled devices of a complete wheelchair. This document does not apply to resistance to ignition of structural parts of a wheelchair. This document does not cover changes in resistance to ignition as a result of regular washing or use of the postural support devices. This document allows for the separate testing of components of a wheelchair that are normally used in the horizontal plane (e.g. a seat cushion) from those normally used in the vertical plane (e.g. a back support). This document describes testing an assembly of the composite of materials as used in the component. The results of the tests in this document do not give any indication of the resistance to ignition of any of the separate individual materials of the test sample. NOTE 1 The intent of this document is primarily to address components that interface with the human body, such as cushions for positioning, or whose described purpose is that of protecting skin tissue against pressure, shear, and maceration related damage, as well as textile, foam, and plastic-based postural support devices. Materials chosen are to comply with biocompatibility requirements and risk management guidance of ISO 10993–1, which includes consideration of cytotoxicity, sensitization, and irritation evaluations for devices making contact with the skin. The pass criteria within this document have been set at a basic minimal level and are less severe than current requirements in some countries. Where practical, manufacturers are to use materials with superior resistance to ignition, when the overall risk analysis indicates the benefits outweigh any unintended harm, in accordance with ISO 14971. NOTE 2 Requirements for the control of risks from sources of fire created by electrical and electronic components are included in ISO 7176-14.

 

This document specifies test methods for the measurement of the physical degradation of textile materials under the simulated industrial composting conditions in a laboratory scale. Degradation rates considered in this document are mechanical properties and surface area loss. Any pretreatment of textile materials is not allowed prior to testing. This method is not suitable to assess biodegradation or mineralization of textile materials. This method is intended for textile materials marketed as compostable or likely to enter industrial composting streams and not intended to evaluate durability of textile materials for non-compost end-of-life.

This document covers both the development of content specifically for mobile devices and the transformation of UA content developed for other formats (responsive design). This document provides the main steps of the process for designing and testing of UA information. This document does not include technical specifications of the visual, auditory, tactile, and other sensorial input and output methods for the mobile device interface.

 

ISO 20471:2013 specifies requirements for high visibility clothing which is capable of visually signalling the user's presence. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by operators of vehicles or other mechanized equipment during daylight conditions and under illumination of headlights in the dark. Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective clothing.

 

ISO 9308-2:2012 specifies a method for the enumeration of E. coli and coliform bacteria in water. The method is based on the growth of target organisms in a liquid medium and calculation of the "Most Probable Number" (MPN) of organisms by reference to MPN tables. This method can be applied to all types of water, including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria. However it must not be used for the enumeration of coliform bacteria in marine water. When using for the enumeration of E. coli in marine waters, a 1?10 dilution in sterile water is typically required, although the method has been shown to work well with some marine waters that have a lower than normal concentration of salts. In the absence of data to support the use of the method without dilution, a 1?10 dilution is used. This method relies upon the detection of E. coli based upon expression of the enzyme b-D-glucuronidase and consequently does not detect many of the enterohaemorhagic strains of E. coli, which do not typically express this enzyme. Additionally, there are a small number of other E. coli strains that do not express b-D-glucuronidase. The choice of tests used in the detection and confirmation of the coliform group of bacteria, including E. coli, can be regarded as part of a continuous sequence. The extent of confirmation with a particular sample depends partly on the nature of the water and partly on the reasons for the examination. The test described in ISO 9308-2:2012 provides a confirmed result with no requirement for further confirmation of positive wells.

 

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases.

This document does not apply to machinery for harvesting and conditioning flax manufactured before the date of publication.

 

This document specifies methods for calculation of the thermal and fluid dynamic characteristics of chimneys serving more than one combustion appliance. This part of prEN 13384 covers the following cases: a) where the chimney is connected with more than one connecting flue pipe from individual or several combustion appliances in a multi-inlet arrangement; b) where the chimney is connected with an individual connecting flue pipe connecting more than one combustion appliance in a cascade arrangement; or c) where the balanced flue chimney consists of a collective air supply duct serving the combustion air to more than one combustion appliance. Each combustion appliance is connected to an individual flue duct located inside the collective air supply duct to the outlet. Every individual flue duct has a temperature class not exceeding T120, a pressure class of P1, M1 or H1 and a sootfire class of O. The case of multiple inlet cascade arrangement is covered by the case a). This part of prEN 13384 deals with chimneys operating under negative pressure conditions (there can be positive pressure condition in the connecting flue pipe) and with chimneys operating under positive pressure conditions and is valid for chimneys serving combustion appliances for liquid, gaseous and solid fuels. For positive pressure chimneys (case a), b) and c)) this part only applies if any combustion appliance which is out of action can be positively isolated to prevent flue gas back flow. This part of EN 13384 does not apply to: - chimneys with different thermal resistance or different cross-section in the various chimney segments. This part does not apply to calculate energy gain; - chimneys with open fire places, e.g. open fire chimneys or chimney inlets which are normally intended to operate open to the room; - chimneys which serve different kinds of combustion appliances regarding natural draught, fan assisted, forced draught or combustion engine. Fan assisted combustion appliances with draught diverter between the fan and the chimney are considered as natural draught combustion appliances; - chimneys with multiple inlets from more than 5 storeys. (This does not apply to balanced flue chimney.); - chimneys serving combustion appliances with open air supply through ventilation openings or air supply ducts, which are not installed in the same air supply pressure region (e.g. same side of building).

 

This document is applicable to gravimetrically pellet-fed room heaters, inset appliances and cookers. The intended use of the appliances is space heating in residential buildings and can be cooking. These appliances burn wood pellets only as specified in EN ISO 17225. This document is not applicable to appliances which are in addition intended for non-gravimetrically fuelling with wood logs (e.g. from the front on top of the burner pot or even if a cover of the burner pot is provided and intended to be used). This document is not applicable to appliances with fan assisted combustion air, appliances that are mechanically or to appliances fitted with a boiler (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems. This document is not applicable to appliances that can operate with fire door open. This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of solid fuel burning room heaters.

 

This document specifies a method for instrumental analysis by equilibration-isotope ratio mass spectrometry (Eq-IRMS) of liquid, aqueous food matrices to determine ¹8O/16O isotope ratios of the water of the product. The ¹8O/¹6O isotope ratios obtained by following this document are expressed as d¹8O values relative to internationally recognised reference materials. This document does not apply to sample preparation. It is assumed that the food sample has been pre-treated as necessary and homogenised. Similarly, the interpretation of the obtained d¹8O values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials. Although other instrumental techniques can be applied to determine d¹8O values in liquid, aqueous food materials, these other techniques are not covered by this document.
