This document specifies requirements and recommendations for ultrasonic gas flowmeters (USMs), which utilize the transit time of acoustic signals to measure the flow of single phase homogenous gases in closed conduits. This document applies to transit time ultrasonic gas flowmeters used for custody transfer and allocation metering, such as full-bore, reduced-area, high-pressure, and low-pressure meters or any combination of these. There are no limits on the minimum or maximum sizes of the meter. This document can be applied to the measurement of almost any type of gas, such as air, natural gas, and ethane. Included are flow measurement performance requirements for meters of two accuracy classes suitable for applications such as custody transfer and allocation measurement. This document specifies construction, performance, calibration, diagnostics for meter verification, and output characteristics of ultrasonic meters for gas flow measurement and deals with installation conditions. NOTE It is possible that national or other regulations apply which can be more stringent than those in this document.
This document provides guidance on the type and extent of soil characterization necessary for the evaluation of human exposure to substances present in possibly leading to adverse effects. It does not provide guidance on: — the design or selection of numerical models that can be used to estimate exposure; — potential exposure to radioactivity, pathogens or asbestos in soil. Background information is provided on human health related to exposure to soil and the influence on exposure via different pathways. NOTE 1 For convenience "soil" in this document also includes "soil material" unless stated otherwise. NOTE 2 Overall exposure can be due to potentially harmful substances (PHSs) in soil, groundwater and air. Exposure to those in soil can be direct (e.g. through inhalation, ingestion, cutaneous contact), or indirect (through the consumption of plants or animals that have taken up substances of concern). NOTE 3 The evaluation of the possible impact on human health of potentially harmful substances is most commonly required when these are present as a result of human activity (e.g. on old industrial sites) but can sometimes be required when they are present naturally. NOTE 4 Soil characterization precedes the assessment of the compatibility between soil and its use (i.e. soil quality assessment). Tools such as a conceptual site model (CSM) and health risk assessment can be used to aid this assessment. NOTE 5 Soil characterization can be used to develop an overview of population exposure to soil. Other International Standards are available that can aid the characterization of other media (e.g. surface and groundwater), in terms of their possible adverse effects on humans.
This document defines a framework for advanced reflective and transmissive layouts and colorimetric values of targets for use in the calibration and characterization of image capturing devices. This document defines a framework for target creation and data reporting. This framework can be used for both ISO defined and custom targets for both reflective and transmissive use. Self-emissive targets are not covered by this document.
This document specifies the minimum operational, functional and performance requirements, as well as methods of testing and the corresponding required test results, for heading control systems installed on board ships conforming to performance standards adopted by IMO Resolution MSC.64(67), Annex 3. In addition, it takes into account parts of IMO resolution A.694(17) to which IEC 60945 is associated. Also it takes into account IMO resolution MSC.302(87) on bridge alert management (BAM). In this document, the ship models of simulators used for performance testing are based on those from ships with a combined system of propeller propulsion and conventional rudder, with a speed range of up to 30 knots. The test results are considered also to be valid for ships with multiple parallel operated rudders. NOTE The text in this document that is identical to that in IMO Resolution A.342(IX), as amended by IMO Resolution MSC.64(67) Annex 3, and IMO Resolution A.694(17), is printed in italics.
This document specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at the time of manufacture for refillable seamless steel gas cylinders and tubes with water capacities up to and including 450 l. It is applicable to cylinders and tubes for compressed, liquefied and dissolved gases and for normalized or normalized and tempered steel cylinders and tubes.
This document specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at time of manufacture for refillable seamless steel gas cylinders and tubes with water capacities up to and including 450 l. it is applicable to cylinders and tubes for compressed, liquefied and dissolved gases and for quenched and tempered steel cylinders and tubes with an actual tensile strength Rma ≥ 1 100 MPa. It is not applicable to cylinders and tubes with Rma, max > 1 300 MPa for diameters >140 mm and guaranteed wall thicknesses a′ ≥ 12 mm and for cylinders and tubes with Rma, max > 1 400 MPa for diameters ≤140 mm and guaranteed wall thicknesses a′ ≥ 6 mm because, beyond these limits, additional requirements can apply.
This document specifies methods for the determination of chlorine and/or bromine present in raw rubber as well as vulcanized or unvulcanized rubber compounds. The methods are applicable to natural rubbers and to the following synthetic rubbers: isoprene, styrene-butadiene, butadiene, butyl, halogenated butyl, nitrile, ethylene-propylene, chloroprene and epichlorohydrin.
This document specifies procedures for measuring mechanical mobility and other frequency-response functions of structures excited by means of an impulsive force generated by an exciter which is not attached to the structure under test. It is applicable to the measurement of mobility, accelerance or dynamic compliance, either as a driving point measurement or as a transfer measurement, using impact excitation. Other excitation methods, such as step relaxation and transient random, lead to signal-processing requirements similar to those of impact data. However, such methods are outside the scope of this document because they involve the use of an exciter which is attached to the structure. The signal analysis methods covered are all based on the discrete Fourier transform (DFT), which is performed mostly by a fast Fourier transform (FFT) algorithm. This restriction in scope is based solely on the wide availability of equipment which implements these methods and on the large base of experience in using these methods. It is not intended to exclude the use of other methods currently under development. Impact excitation is also widely used to obtain uncalibrated frequency-response information. For example, a quick impact test which obtains approximate natural frequencies and mode shapes can be quite helpful in planning a random or sinusoidal test for accurate mobility measurements. These uses of impact excitation to obtain qualitative results can be a first stage for mobility measurements. This document is limited to the use of impact excitation techniques for making accurate mobility measurements.
This document specifies the requirements, test methods and performance criteria for transmission path isolators for use in fire detection and fire alarm systems for buildings (for general requirements and definitions, see ISO 7240‑1). Means of isolation or protection incorporated within control and indicating equipment are not covered by this document.
