IEC 61970-457:2024 specifies a standard interface for exchanging dynamic model information needed to support the analysis of the steady state stability (small-signal stability) and/or transient stability of a power system or parts of it. The schema(s) for expressing the dynamic model information are derived directly from the CIM, more specifically from IEC 61970-302.
The scope of this document includes only the dynamic model information that needs to be exchanged as part of a dynamic study, namely the type, description and parameters of each control equipment associated with a piece of power system equipment included in the steady state solution of a complete power system network model. Therefore, this profile is dependent upon other standard profiles for the equipment as specified in IEC 61970-452: CIM static transmission network model profiles, the topology, the steady state hypothesis and the steady state solution (as specified in IEC 61970-456: Solved power system state profiles) of the power system, which bounds the scope of the exchange. The profile information described by this document needs to be exchanged in conjunction with IEC 61970-452 and IEC 61970-456 profiles’ information to support the data requirements of transient analysis tools. IEC 61970-456 provides a detailed description of how different profile standards can be combined to form various types of power system network model exchanges.
This document supports the exchange of the following types of dynamic models:
• standard models: a simplified approach to exchange, where models are contained in predefined libraries of classes interconnected in a standard manner that represent dynamic behaviour of elements of the power system. The exchange only indicates the name of the model along with the attributes needed to describe its behaviour.
• proprietary user-defined models: an exchange that would provide users the ability to exchange the parameters of a model representing a vendor or user proprietary device where an explicit description of the model is not described in this document. The connections between the proprietary models and standard models are the same as described for the standard models exchange. Recipient of the data exchange will need to contact the sender for the behavioural details of the model.
This document builds on IEC 61970-302, CIM for dynamics which defines the descriptions of the standard dynamic models, their function block diagrams, and how they are interconnected and associated with the static network model. This type of model information is assumed to be pre-stored by all software applications hence it is not necessary to be exchanged in real-time or as part of a dynamics model exchange.

This document specifies requirements and test methods for marketed and delivered automotive liquefied petroleum gas (LPG), with LPG defined as low pressure liquefied gas composed of one or more light hydrocarbons which are assigned to UN 1011, 1075, 1965, 1969 or 1978 only and which consists mainly of propane, propene, butane, butane isomers, butenes with traces of other hydrocarbon gases.
This standard is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
NOTE   For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health arising through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. Naked flames, unprotected electrical equipment electrostatic hazards etc. are sources of ignition for LPG.
LPG in liquid form can cause cold burns to the skin. The national health and safety regulations apply.
LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.
CAUTION - One of the tests described in this European Standard involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to.

This document describes the methods that are available to perform a spectral analysis of a pavement surface profile. It specifies a method for performing spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement texture amplitude as a function of the distance along a straight or curved trajectory over the pavement. It also details an alternative (non-preferred) method to obtain these spectra: a) constant-percentage bandwidth obtained by digital filtering (normative method); b) constant narrow bandwidth frequency analysis by means of discrete Fourier transform (DFT), followed by a transformation of the narrow-band spectrum to an octave- or one-third-octave-band spectrum (informative). The result of the frequency analysis will be a spatial frequency (or texture wavelength) spectrum in constant-percentage bandwidth bands of octave or one-third-octave bandwidth. The objective of this document is to standardize the spectral characterization of pavement surface profiles. This objective is pursued by providing a detailed description of the analysis methods and related requirements for those who are involved in pavement characterization but are not familiar with general principles of frequency analysis of random signals. These methods and requirements are generally applicable to all types of random signals; however, they are elaborated in this document for their use in pavement surface profile analysis. NOTE The spectral analysis as specified in this document cannot express all characteristics of the surface profile under study. In particular, the effects of asymmetry of the profile, e.g. the difference of certain functional qualities for “positive” and “negative” profiles cannot be expressed by the power spectral density, as it disregards any asymmetry of the signal (see Annex B).

IEC 63305:2024 specifies methods and procedures for calibration of vector receivers in the frequency range 5 Hz to 10 kHz, which are applicable to vector receivers based on the two different principles. In addition, it describes an absolute method of inertial vector receiver calibration in air using optical interferometry. Usually, acoustic wave vector receivers are designed and constructed based on one of two principles. One is the sound pressure difference (gradient) principle. When measuring with this sensor, the vector receiver is rigidly fixed on a mount and supported in water. The other is the co-vibrating (inertial) principle. When measuring with this sensor, the vector receiver is suspended on a mount and supported in water in a non-rigid manner, which allows the vector receiver co-vibrate in the same direction as the sound particle in the sound wave field. Many methods have been used to calibrate vector receivers, such as free-field calibration, calibration in standing wave tube and calibration in a travelling wave tube.

This fourth edition cancels and replaces the third edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) replaced active monitoring with transient loss for measurements during test; b) harmonized recommended severities according to IEC 61753-1.

SIGNIFICANCE AND USE
5.1 The test procedures and interlaboratory study report that result from coordinator compliance with this Practice are intended to include all information required for an ASTM Test Method and its associated Research Report; the interlaboratory study is to be conducted in compliance with Practice E691, also as required for an ASTM Test Method.3 The reason that the content of this Practice is not prepared as an actual ASTM Test Method is as follows. ASTM regulations preclude reference (in a Standard) to patented or otherwise proprietary test apparatus where “alternatives exist”.4 While a proprietary apparatus may be mentioned in the Test Method’s Research Report, this would prevent the Test Method from being a standalone document containing all information necessary for testing. As such, a standalone Test Method could only be for a non-proprietary apparatus design, with this design expressed in terms of physical characteristics and performance specifications sufficient to enable the reader to fabricate their own “identical” copy of the design. Further, to achieve consensus approval and publication of such a Test Method, it could be considered necessary that ILS results for this design include data from devices made by different entities. However, typical walkway tribometer designs (versus other types of test apparatus) are sufficiently complex that full documentation of all performance-affecting physical characteristics (sufficient that a reader could build one) may be impractical. European standard EN 16165 Annexes C and D illustrate what physical and performance characteristics are and are not documented in that standard’s specifications for two non-proprietary tribometers. In general, each different tribometer design may have advantages and disadvantages for testing different surfaces, and this Practice provides a rigorous and standardized structure for creating tribometer test procedures and interlaboratory study reports that would comply with the requirements fo...
SCOPE

ABSTRACT
This specification covers requirements, test methods, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to a certain temperature. These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. The components are intended for use in residential and commercial, hot and cold, potable water distribution systems. The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. CPVC 4120 pipe, tubing, and fittings shall be classified by a single standard dimension ratio which shall be SDR 11, by a certain maximum continuous use temperature and by a certain diameter range for nominal pipe or tubing. CPVC plastic-to-metal transition fittings intended for use up a certain temperature are classified on the basis of resistance to failure by thermocycling. The chlorinated poly(vinyl chloride) plastics are categorized by two criteria: basic short-term properties and long-term hydrostatic strength. These short-term properties include mechanical strength, heat resistance, flammability, and chemical resistance which shall be determined after performing different tests. A test shall also be conducted in order to determine the long-term hydrostatic strength of CPVC 41 pipe, tubing, and fittings.
SCOPE
1.1 This specification covers requirements, test methods, assembly, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to and including 180 °F (82 °C). These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. Requirements and methods of test are included for materials, workmanship, dimensions and tolerances, hydrostatic sustained pressure strength, and thermocycling resistance. The components covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems.

SCOPE
1.1 This test method covers the observation of the temperatures at which triangular pyramids (cones) prepared from coal and coke ash attain and pass through certain defined stages of fusing and flow when heated at a specified rate in controlled, mildly reducing, and where desired, oxidizing atmospheres.  
1.2 The test method is empirical, and strict observance of the requirements and conditions is necessary to obtain reproducible temperatures and enable different laboratories to obtain concordant results.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3.1 All percentages are percent mass fractions unless otherwise noted.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Further discussion of these and other technical issues is given in the Appendix.
SCOPE
1.1 This test method covers the determination of length change of mortar bars immersed in a sulfate solution. Mortar bars made using mortar described in Test Method C109/C109M are cured until they attain a compressive strength of 20.0 MPa ± 1.0 MPa [3000 psi ± 150 psi], as measured using cubes made of the same mortar, before the bars are immersed.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is used to determine the amount of expansion of a mortar bar when it is stored in water. The amount of mortar-bar expansion may relate to the amount of sulfate in the cementitious material; expansion may become excessive when the cementitious material contains too much sulfate.  
4.2 Some cementitious material specifications limit the amount of sulfate contained in those materials by requiring that the amount of expansion in water not exceed a specified value.
SCOPE
1.1 This test method covers the determination of the expansion of mortar bars made using hydraulic cementitious materials, of which sulfate is an integral part.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
