This document specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for internal combustion engines. The diesel fuels covered include “bio-diesels” which consist of the methyl ester of rape seed oil at levels up to 20 % by volume in conventional diesel fuels. This document can also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a “line call-out” of tests for specific applications where these are not covered by the main types specified (see example in Annex E). In this case, the hose or tubing would not carry any marking showing the number of this document but can detail the OEM's own identification markings as shown on their part drawings.

 

ISO 19743:2017 specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225-1:2014, Table 1.

 

This document describes fuelling protocols for liquid hydrogen (LH2), defining the minimum design, installation and operation requirements for a safe, as well as fast, efficient and interoperable hydrogen transfer from the fuelling station to the vehicle fuel system. This document applies to land vehicles of all types equipped with a liquid hydrogen storage system fulfilling ISO 13985 requirements. The protocols described in this document are currently limited to vehicles with storage system total internal volume equal to or comprised between 0,6 m3 and 4 m3. Further hydrogen applications may apply the requirements of this standard. However, further specific requirements that can be necessary for the safe operation of such fuelling are not addressed in this document. This document specifies the requirements for liquid hydrogen fuelling and dispensing systems, fuelling station - vehicle interface and vehicle storage system in order to minimise the risk of fire, explosion or any other hydrogen adverse effects to an acceptable level, especially during and after the fuelling process.

 

ISO 15015:2011 specifies the requirements and test methods for solid flat extruded sheets of impact-modified acrylonitrile-styrene copolymer materials: acrylonitrile-butadiene-styrene (ABS), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) (commonly known as AES) and acrylonitrile-styrene-acrylate (ASA), without fillers or reinforcing materials. This International Standard also applies to ABS, AEPDS and ASA sheet in rolled form. It applies only to thicknesses from 0,25 mm to 20,0 mm.

This document describes a systematic approach to assess potential occupational risks related to the dermal exposure to chemical agents at the workplace. This approach provides guidance to identify hazards, exposure routes, exposed body parts and potential consequences of exposure with respect to skin uptake and local skin effects, using qualitative and quantitative approaches. NOTE There is a relation between skin contamination and inadvertent ingestion. This document is aimed at occupational hygienists, researchers and other safety professionals to assist recognition of potential dermal exposure and its potential consequences.

 

Tämän standardin tarkoituksena on helpottaa ja yhdenmukaistaa oikean suojamaaliyhdistelmän valitsemista prosessi- ja metalliteollisuudelle. Suojamaaliyhdistelmät perustuvat standardisarjaan SFS-EN ISO 12944 ja teollisuudessa saatuihin kokemuksiin. Tämä standardi täydentää standardisarjaa mm. esikäsittelyt kunnossapitoon (St2), esikäsittelyt sinkki- ja alumiinialustoille (SaS) sekä ruostumattomille teräsalustoille (SaS), kunnossapitojärjestelmät, alumiini- ja ruostumattomien teräsalustojen suojamaalijärejstelmät, kuiva lämpörasitus. Suojamaaliyhdistelmät on tarkoitettu ilmastorasitusluokkiin C2…C5 ja upotusrasituksiin Im1, Im2 ja Im3 sekä erikoisrasituksiin, kuten polttonesteet ja liuotteet. Tässä standardissa ei käsitellä jauhemaalausta.

 

This document specifies requirements for the biobanking of human natural killer (NK) cells derived from human pluripotent stem cells (hPSCs), including the requirements for the differentiaton, culture, characterization, quality control, storage, thawing and transport of NK cells. Requirements for the collection of biological source material, the transport to and reception of biological source material and hPSCs at the biobank, as well as the establishment, expansion and QC of hPSCs are covered in ISO 24603. This document is applicable to all organizations performing biobanking of human NK cells used for research and development in the life sciences. This document does not apply to human NK cells for the purpose of in vivo application in humans, clinical applications or therapeutic use.

 

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom.

 

This document establishes a model-free approach for the isoconversional kinetic analysis of chemical reactions and phase transitions. The isoconversional principle is based on the assumption that the reaction rate at a given conversion depends solely on the temperature, i.e., is independent on the scan rate. This document establishes a method for the determination of the activation energy as a function of the conversion of the reaction or transition. The method is applicable to dynamic and isothermal temperature program measurements done by Differential Scanning Calorimetry (DSC) or Thermogravimetry (TG). It can be applicable to other measurement techniques, too, that enable the determination of conversion curves. The method is applicable to the prediction of the kinetic behaviour of reactions and transitions even in temperature regions that are not experimentally accessible. The method is not applicable in the glassy state of polymers.

 

This document specifies a method for the determination of the penetration temperature of thermoplastics using thermomechanical analysis (TMA).

 

This International Standard specifies procedures for detecting the presence of porosity in a protective paint system of any thickness on a steel or other metallic substrate. The procedures given in this International Standard are based on methods using two different types of test equipment, the choice of equipment depending on the dry film thickness. These procedures are only applicable to the testing of electrically non-conductive parts of a paint system. The test methods specified are mainly intended for use with new coatings, but can also be used for coatings which have been in service for some time. In the latter case, it is important to bear in mind that the coating might have been penetrated by substances in contact with the coating during service.

 

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. The density of plastic materials can depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification.
