Brown coals are classified in this International Standard according to the following properties: total moisture content calculated on the ash-free basis; tar hiels calculated on the dry, ash-free basis. In tables class numbers, group number and code numbers of brown coal types are given.

This international standard applies to the Digital Governance part of the mobility system of a city engaged in sustainability. It should be used to achieve sustainability goals of the local community. It targets Urban Mobility and its connections with intercity and other long-distance transport solutions. It applies to mobility of people and goods.

1. Principal method This draft specifies the principal method for laser shearography NDE inspection of FRP composites. Here, out-of-plane surface displacement gradients are monitored, using coaxial illumination and observation, both effectively perpendicular to the part surface. Defect detection relies on local influences on the global surface deformation from sub-surface anomalies under the…

This International Standard specifies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, internal combustion engine-driven machines for abrasive chains, intended to be used by a single operator in the cutting of construction materials, such as concrete, stone and metal. It is applicable only to those machines designed purposely for…

This International Standard specifies detailed calculation procedures for determining the thermal and optical transmission properties (e.g., thermal transmittance, total solar energy transmittance) of window, door and clear window (BIPV) systems based on the most up-to-date algorithms and methods, and the relevant solar and thermal properties of all components. Products covered by this…

ISO 3170:2004 specifies the manual methods to be used for obtaining samples of liquid or semi-liquid hydrocarbons, tank residues and deposits from fixed tanks, railcars, road vehicles, ships and barges, drums and cans, or from liquids being pumped in pipelines. ISO 3170:2004 applies to the sampling of petroleum products, crude oils and intermediate products, which are stored in tanks at or near…

ISO 11970:2016 specifies how a welding procedure specification (WPS) for production welding of steel castings is qualified. It defines the conditions for the execution of welding procedure qualification tests and the limits of validity of a qualified welding procedure for all practical welding operations within the range of essential variables. Tests are intended to be carried out in accordance…

This international standard provides guidelines for the classification and performance of leather upholstered products. This international standard is applicable for products made of leather upholstered for all levels of production. This international standard is applied, if the upholstered material is made of leather or rather is a leather semifinished product in the sense of ISO 15115.

Scope of the proposed deliverable. This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2). Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the…

This International Standard specifies a method for the determination of the electrical resistivity of cathode blocks and baked anodes used in the production of aluminium, using samples at ambient temperature.
