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.
Piping systems for rehabilitation of underground drains, sewers and water supply networks — Part 1: ...
This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation by means of renovation and trenchless replacement of underground non-pressure and pressure drainage and sewerage networks and water supply networks, which transport water intended for human consumption, including raw water pipelines.
It is applicable to polyethylene…
Piping systems for rehabilitation of underground drains, sewers and water supply networks — Part 3: ...
This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation by means of renovation of underground non-pressure drainage and sewerage networks.
It is applicable to unplasticized poly (vinyl chloride) (PVC-U) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to…
Numerical welding simulation — Execution and documentation
ISO/TS 18166:2016 provides a workflow for the execution, validation, verification and documentation of a numerical welding simulation within the field of computational welding mechanics (CWM). As such, it primarily addresses thermal and mechanical finite element analysis (FEA) of the fusion welding (see ISO/TR 25901:2007, 2.165) of metal parts and fabrications.
CWM is a broad and growing area of…
