This standard specifies the principle of phase quantitative analysis of residual α-quartz in silica bricks by X-ray diffraction, apparatus, reference materials, sample preparation, standard curve establishment, test procedures, results and calculations, and test report. This standard applies to the phase quantitative analysis of residual α-quartz in silica bricks, and the phase quantitative…

This standard defines requirements and guidelines to help organisations understanding and mainstreaming biodiversity’s protection, conservation, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, within their activities. This standard is suitable for all kind of organisations (e.g. economic operators,…

ISO 14577-1:2015 specifies the method of instrumented indentation test for determination of hardness and other materials parameters for the following three ranges: macro range: 2 N ≤ F ≤ 30 kN; micro range: 2 N > F; h > 0,2 µm; and nano range: h ≤ 0,2 µm. For the nano range, the mechanical deformation strongly depends on the real shape of indenter tip and the calculated material parameters…

The proposed standard will establish a management system for determining the origin (provenance) of materials containing rare earths and tracking them as these materials move through the supply chain between suppliers of rare earth oxides and producers of rare earth containing permanent magnets.

Preparation of a new ISO standard using a recently published CEN standard as a basis. The WG will examine this in detail and make any technical changes as required to ensure conformance with specific ISO requirements It is expected that the ISO standard will closely follow the requirements of the published CEN standard whilst complying with the ISO template

ISO 10896-2:2016 specifies general safety requirements for slewing rough-terrain variable-reach trucks (hereafter known as "trucks"), consisting of a lower chassis with a slewing upper structure equipped with a telescopic lifting means (pivoted boom), on which a load handling device (e.g., carriage and fork arms) is typically fitted. Fork arms and other integrated attachments are…

This part of ISO 19152 provides the concepts and detailed structure for standardization in the land administration domain. In order to achieve public policy objectives, some regulations use geographical spaces for mandating or enabling particular behaviours or outcomes. This part of ISO 19152 defines a general schema for valuation information systems in the context of the land administration.…

ISO 8642:2008 specifies test methods for metric self-locking nuts with MJ threads intended for use in aerospace construction at maximum operating temperature greater than 425 °C. It describes the test device and the method for each test. ISO 8642:2008 applies to self-locking nuts as defined above, provided that the relevant documents (dimensional standard, drawing, procurement specification, etc…

ISO 6578:2017 specifies the calculation procedure to convert the volume of liquefied petroleum gas (LPG) and liquefied natural gas (LNG) under the conditions at the time of measurement to the equivalent volume of liquid or vapour at the standard condition, i.e. 15 °C and 101,325 kPaA, or to the equivalent mass or energy (calorific content). It applies to the quantities of refrigerated hydrocarbon…

This document provides appraisal framework to create and use urban management information derived from statistics, objectives, indicators and long-term goals for sustainable development of cities and communities. This document enables numerous combinations of data sources and data processing methods, making it easier to create and maintain urban management information and get ready for value…
