ASTM F914/F914M-20 没有附加载荷处理附件的空中人员装置的声发射的标准试验方法

1.1 This test method describes a procedure for nondestructive testing using acoustic emission (AE) testing for aerial personnel devices, which do not have a supplemental load handling attachment. 1.1.1 Equipment Covered—This test method covers the following types of vehicle-mounted insulated aerial personnel devices: 1.1.1.1 Extensible boom aerial personnel devices, 1.1.1.2 Articulating boom aerial personnel devices, and 1.1.1.3 Any combination of 1.1.1.1 and 1.1.1.2. 1.1.2 Equipment Not Covered—This test method does not cover any of the following equipment: 1.1.2.1 Material-handling aerial devices, 1.1.2.2 Digger-derricks with platform, and 1.1.2.3 Cranes with platform. 1.2 The AE test method is used to detect and area-locate emission sources. Verification of emission sources may require the use of other nondestructive test (NDT) methods, such as radiography, ultrasonics, magnetic particle, liquid penetrant, and visual inspection. Warning—This test method requires that external loads be applied to the superstructure of the vehicle under test. During the test, caution must be taken to safeguard personnel and equipment against unexpected failure or instability of the vehicle or components. NOTE 1—This test method is not intended to be a stand alone NDT method for the verification of the structural integrity of an aerial device. Other NDT methods should be used to supplement the 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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. 1.5 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.

BS EN ISO 11203:2009+A1:2020 声学 机械和设备发出的噪音 根据声功率级确定工作站和其他指定位置的发射声压级

1   Scope 1.1   General This International Standard specifies two methods for determining the emission sound pressure levels of machinery and equipment, at a work station and at other specified positions nearby, by calculation from the sound power level. The principal purpose of this determination is to permit comparison of the performance of different units of a given family of machinery or equipment, under defined environmental conditions and standardized mounting and operating conditions. The data obtained may also be used for the declaration and verification of emission sound pressure levels as specified in ISO 4871. Emission sound pressure levels are determined with the same frequency weighting and time weighting, or in the same frequency bands, as those for which sound power levels have been determined. NOTES 1 The contents of this document and related International Standards are summarised in ISO 11200:2014, Table 1. 2 At any given position in relation to a particular machine, and for given mounting and operating conditions, the emission sound pressure levels determined by the method of this International Standard will in general be lower than the directly measured sound pressure le...

ASTM E750-15(2020) 表征声发射仪器的标准实践

1.1 This practice is recommended for use in testing and measuring operating characteristics of acoustic emission electronic components or units. (See Appendix X1 for a description of components and units.) It is not intended that this practice be used for routine checks of acoustic emission instrumentation, but rather for periodic evaluation or in the event of a malfunction. The sensor is not addressed in this document other than suggesting methods for standardizing system gains (equalizing them channel to channel) when sensors are present. 1.2 Where the manufacturer provides testing and measuring details in an operating and maintenance manual, the manufacturer’s methods should be used in conjunction with the methods described in this practice. 1.3 The methods (techniques) used for testing and measuring the components or units of acoustic emission instrumentation, and the results of such testing and measuring should be documented. Documentation should consist of photographs, screenshots, charts or graphs, calculations, and tabulations where applicable. 1.4 AE systems that use computers to control the collection, storage, display, and data analysis, might include waveform collection as well as a wide selection of measurement parameters (features) relating to the AE signal. The manufacturer provides a specification for each system that specifies the operating range and conditions for the system. All calibration and acceptance testing of computer-based AE systems must use the manufacturer’s specification as a guide. This practice does not cover testing of the computer or computer peripherals. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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.

BS EN ISO 11200:2014+A1:2020 声学 机械和设备发出的噪音 确定工作站和其他指定位置排放声压级的基本标准的使用指南

1   Scope This International Standard is the frame standard introducing the basic group, ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205, on the determination of emission sound pressure levels at work stations and other specified positions . It gives guidance for: — facilitating the writing of noise test codes ; — providing physical explanations of this noise emission quantity compared to other noise quantities (see 4.1 to 4.3); — comparing the different measurement methods offered by the group (see Table 1); — facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6). This International Standard is largely based on flow charts and tables. Case studies are described. The guidance given applies to airborne sound only. It is for use in noise testing, in general, and in the preparation of noise test codes , in particular. A standardized noise test code is intended to select standards from the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group, which are the most appropriate to the machinery family it covers, and which give detailed requirements on mounting and operating conditions for the...
