Road vehicles — Liquefied natural gas (LNG) fuel systems — Part 1: Safety requirements
This document specifies the minimum safety requirements applicable to liquefied natural gas (LNG) on-board fuel system intended for use on the types of motor vehicles defined in ISO 3833.
This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using liquefied natural gas in accordance with the ISO 15403 series. It is not applicable to original-production and…
ISO 3953:2011 specifies a method for the determination of tap density, i.e. the density of a powder that has been tapped into a container under specified conditions.
Road vehicles — Liquefied natural gas (LNG) fuel systems — Part 2: Test methods
This document specifies performance and general test methods for liquefied natural gas fuel system components intended for use on the types of motor vehicles defined in ISO 3833.
This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using liquefied gas in accordance with the ISO 15403 series. It is not applicable to the following: original-production and converted…
Coal — Methods for petrographic analysis — Part 5: Method of determining microscopically the reflect...
ISO 7404-5:2009 specifies the methods for determining the reflectance of vitrinite of coals microcopically on the polished surfaces, immersed in oil. The methods are applicable to coals from single seams or coal blends covering the whole range of low-, medium- and high-rank coal.
Vitrinite reflectance measurements can be used to characterize the components within blends. Measures can be taken to…
Coal — Methods for petrographic analysis — Part 4: Method of determining microlithotype, carbomineri...
ISO 7404-4:2017 specifies a method, using a graticule with 20 crossline intersections, for determining the proportions of microlithotypes, carbominerite and minerite in coals. It applies only to determinations made on polished particulate blocks using reflected white light (about 400 nm to 700 nm). Additional blue, blue-violet or UV light excitation (365 nm to 440 nm) for better identification of…
Coal — Methods for petrographic analysis — Part 1: Vocabulary
ISO 7404-1:2016 defines terms that are used in connection with both maceral and microlithotype analyses, and with the determination of the reflectance of vitrinite. It applies to the terms used in the examination of coal of all ranks.
ISO 7404-1:2016 is not intended to be a comprehensive glossary of coal petrographic terminology, nor does it attempt to provide sufficient information to allow…
Coal — Methods for petrographic analysis — Part 2: Method of preparing coal samples
ISO 7404-2:2009 specifies methods for preparing a polished particulate block from a sample of crushed coal for analysis by reflectance microscopy. These methods can also be applied to the preparation of a polished, embedded lump of coal.
Coal — Methods for petrographic analysis — Part 3: Method of determining maceral group composition
ISO 7404-3:2009 specifies a method for determining the proportions of the maceral groups (and the minerals, if desired) in coals. ISO 7404-3:2009 is applicable only to determinations made on polished particulate blocks using incident white light. For lower-rank coals, the additional use of the fluorescence mode is necessary to identify liptinites.
