AGF is the process of changing the water in the ground from liquid to solid state in a controlled way by artificial means. This document is applicable to: — civil works (tunnels, shafts, retaining walls, plugs, underpinning …) — environmental works (remediation, cut-off walls, …). This document does not apply to: — permafrost — seasonal frost — mining applications.

 

The function of EN 15430 is to combine any vehicle equipment with different board computers to any client application server.

ISO 10426-1:2009 specifies requirements and gives recommendations for six classes of well cements, including their chemical and physical requirements and procedures for physical testing. ISO 10426-1:2009 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement. ISO 10426-1:2009 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction.

To determine liquid flow, the following steps are necessary: 1) Measure water surface velocity with techniques using radar, laser or video images; 2) Correct the water surface velocity due to wind effects if necessary; 3) Option a: Transform the corrected velocity to a depth-averaged velocity in one segment using the arithmetic methods referring to chapter 7.2, secondly calculate each segment and then create the sum of all segments to obtain the cross-sectional averaged velocity distribution; 3) Option b: Transform the corrected velocity to a cross sectional velocity using the index methods referring to chapter 7.3; 4) Determine the area of the wetted cross section from the stage-area relationship; 5) Obtain discharge of each segment by multiplying the depth-averaged velocity in each segment by the wetted cross-sectional area of each segment. And then create the sum of all segments to obtain whole discharge in cross section. This procedure is applicable to different kinds of channel and river sections. Applications include: — Rivers and streams; — Artificial channels such as drainage ditches and irrigation channels; — Process flows on wastewater treatment plants. For any individual site the method to measure water surface velocity should be selected appropriately, based on the site conditions, nature of the application and uncertainty required. Take a special note that non-contact methods should not be used where a unique relation between surface velocity and depth averaged velocity cannot be established, e.g. where tidal phenomena are present. This is caused by the variations of flow magnitude and direction over depth being highly variable over time under these circumstances. Regarding backwater zones or in the vicinity of obstacles the relation between surface velocity and depth averaged velocity may be more complicated, but even here optical methods may be helpful to at least learn the situation at the surface.

This document, to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed and self-propelled agricultural sprayers for use with plant protection products (PPP) and liquid fertilizer application, as placed on the market by the manufacturer and designed for a single operator only. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this document take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the provisions of this document. This document, taken together with ISO 4254-1, deals with significant hazards, hazardous situations and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and under the conditions foreseeable by the manufacturer (see Annex A), excepting the hazards arising from: — protection of the driver against spray when spraying (see Foreword); — automatically actuated height adjustment systems; — the environment, other than noise; — moving parts for power transmission except strength requirements for guards and barriers. This document is not applicable to sprayers and liquid fertilizer distributors which are manufactured before the date of publication of this document.

 

This document specifies requirements and recommendations for measuring the composition of CO2 streams during post capture pipeline transportation. The primary objective of this document is to establish standardized technical requirements and recommendations necessary for implementing regulations, commercial contracts, inventory ownership and fiscal transactions within the framework of Carbon Capture and Storage (CCS). This document includes measurements up to the storage injection points but does not cover Measurement, Monitoring, and Verification (MMV) once the CO2 has entered the geological storage complex. The differentiation between biogenic and non-biogenic CO2 in a CO2 stream is recognized as highly relevant for accounting purposes. However, the measurement methodologies for the biogenic CO2 fraction fall outside the scope of this document, which covers post-capture pipeline transportation. This document is not intended to differentiate between biogenic CO2 and CO2 produced from non-biogenic sources.
