Oil and gas industries including lower carbon energy - Completion fluids and materials - Part 5: Measuring conductivity of proppants (ISO/DIS 13503-5:2026)

ISO 13503-5:2006 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel packing operations. ISO 13503-5:2006 provides a consistent methodology for testing performed on hydraulic fracturing and/or gravel packing proppants. The "proppants" mentioned henceforth in this part of ISO 13503-5:2006 refer to sand, ceramic media, resin-coated proppants, gravel packing media, and other materials used for hydraulic fracturing and gravel-packing operations. ISO 13503-5:2006 is not applicable for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions.

Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement

This document applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use locally radio-frequency energy. This document covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (2020) (see Definition 3.1.18), this document covers emission requirements related to radio- frequency disturbances in the frequency range of 9 kHz to 18 GHz. ISM equipment which incorporates radio transmit/receive functions ( host equipment with radio functionality) is included in the scope of this document, see Annex F. However, the emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions. NOTE 1 This exclusion only applies to emissions from the intentional radio transmitter. However, combination emissions, for example emissions resulting from intermodulation between the radio and the non -radio subassemblies of the ISM equipment, are not subject to this exclusion. NOTE 2 Emission requirements for induction cooking appliances are specified in CISPR 14 -1 [1]1. Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this document. Robots used for industrial, scientific and medical applications are in the scope of this document. EXAMPLE Welding robots, spraying robots, handling robots, processing robots, assembly robots, medical robots, education and experimental robots. A comprehensive list of robots in the scope of this document is given on the IEC EMC zone. NOTE 3 Flying robots, domestic helper robots, toy robots and entertainment robots are examples of robots in the scope of other CISPR standards. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this document.

Hydrometry – Use of noncontact methods for measuring water surface velocity and determining discharge (ISO/DIS 24577:2026)

Scope of the proposed deliverable To determine liquid flow, the following steps are necessary: 1) Measure water surface (or near surface) velocity with techniques using radar, laser or video images; 2) Adjust wind effects to the water surface velocity; 3) Translate the adjusted velocity to an averaged velocity by applying the velocity index or numerical computation; 4) Determine the area of the wetted cross section from the stage area relationship; and 5) Obtain water discharge by multiplying the averaged velocity by the wetted cross sectional area. This procedure is applicable to different kinds of channel and river section. Applications include: •Rivers and streams; •Artificial channels such as drainage ditches and irrigation channels; •Wastewater flows discharging to sewer or the environment through channels or partially filled pipes; •In sewer measurements; •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 tidal phenomenon is present.

Eurocode 8 - Design of structures for earthquake resistance - Part 1-1: General rules and seismic action

1.1 Scope of EN 1998-1-1 (1) This document is applicable to the design and verification of buildings and other structures for earthquake resistance. It gives general rules relevant to all types of structures, except for structures belonging to consequence classes CC0 or CC4. NOTE For further details on consequence class CC4, see 4.2. (2) This document provides basic performance requirements and compliance criteria applicable to buildings and other structures for earthquake resistance. (3) This document gives rules for the representation of seismic actions and the description of the design seismic situations. NOTE Certain types of structures, dealt with in other parts of Eurocode 8, need supplementary rules which are given in those relevant Parts. (4) This document contains general methods for structural analysis and verification under seismic actions, including base-isolated structures and structures with distributed dissipative systems. (5) This document contains rules for modelling and verification of ultimate strengths and deformations. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document. (2) It is assumed that no change in the structure and in the masses carried by the structure takes place during the construction phase or during the subsequent life of the structure with respect to the design unless proper justification and verification is provided. This applies also to ancillary elements (see 3.1.2). Due to the specific nature of seismic response, this applies even in the case of changes that lead to an increase of the structural resistance. (3) The design documents are assumed to indicate the geometry, the detailing, and the properties of the materials of all structural members. If appropriate, the design documents are also assumed to include the properties of special devices to be used and the distances between structural and ancillary elements. The necessary quality control provisions are assumed to be specified. (4) Members of special structural importance requiring special checking during construction are assumed to be identified in the design documents and the verification methods to be used are assumed to be specified. (5) It is assumed that in the case of high seismic action class (4.1.1(4)), formal quality system plans, covering design, construction, and use, additional to the control procedures prescribed in the other relevant Eurocodes, are specified.
