This standard specifies the characterization of ceramic slurry for use as feedstock in vat photopolymerization additive manufacturing (AM) process. The characterization includes the composition and properties of the slurry, such as solids content, dynamic viscosity, particle size distribution, chemical composition, and solid dispersion stability. This standard also provides available methods…
Document management — 3D use of Product Representation Compact (PRC) format — Part 1: PRC 10001
ISO 14739-1:2014 describes PRC 10001 of a product representation compact (PRC) file format for three dimensional (3D) content data. This format is designed to be included in PDF (ISO 32000) and other similar document formats for the purpose of 3D visualization and exchange. It can be used for creating, viewing, and distributing 3D data in document exchange workflows. It is optimized to store,…
Water quality — Determination of selected estrogens in whole water samples — Method using solid phas...
This document specifies a method for the determination of 5 oestrogens, in whole water samples listed in Table 1. The method uses solid-phase extraction (SPE-disks and/or cartridges) followed by liquid or gas chromatography-mass spectrometry (tandem mass spectrometry and/or High resolution mass spectrometry). It is applicable to the analysis of selected estrogens in surface water containing…
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…
