DIN EN 60645-5:2005 电声学.听力测定设备.第5部分:听觉声阻抗/导纳测量用设备

This standard covers instruments designed primarily for the measurement of acoustic impedance/admittance in the human external acoustic meatus using a stated probe tone. It is recognized that other probe signals may also be used. The standard defines the characteristics to be specified by the manufacturer, lays down performance specifications for three types of instruments and specifies the facilities to be provided on these types. This standard describes methods of test to be used for approval testing and guidance on methods for undertaking routine calibration.The purpose of this standard is to ensure that measurements made under comparable testconditions with different instruments complying with the standard will be consistent.#,,#

ISO 8041:2005 人体振动.测量仪

This International Standard specifies the performance specifications and tolerance limits for instruments designed to measure vibration values, for the purpose of assessing human response to vibration. It includes requirements for pattern evaluation, periodic verification and in-situ checks, and the specification of vibration calibrators for in-situ checks. Vibration instruments specified in this International Standard can be single instruments, combinations of instrumentation or computer-based acquisition and analysis systems. Vibration instruments specified in this International Standard are intended to measure vibrations for one or more applications, such as  hand-transmitted vibration (see ISO 5349-1),  whole-body vibration (see ISO 2631-1, ISO 2631-2, ISO 2631-4), and  low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (see ISO 2631-1). Vibration instruments can be designed for measurement according to one or more of the frequency weightings defined within each of these applications. Three levels of performance testing are defined in this International Standard: a) pattern evaluation, i.e. a full test of the instrument against the specifications defined in this International Standard; b) periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains within the required performance specification, and c) in-situ checks, i.e. a minimum level of testing required to indicate that an instrument is likely to be functioning within the required performance specification.

DIN 45657:2005 声级计.特殊测量任务的附加要求

The document applies to sound level meters, integrating averaging sound level meters and for sound level measurement equipment for special measurement tasks, particularly for measuring the maximum level in consecutive time intervals or for measuring the statistical level distribution. The application of these additional requirements has to be agreed upon separately. Requirements, inspections and limits of permissible error allow for the expanded measurement uncertainty and follow the specifications of DIN EN 61672-1 and DIN EN 61672-2.#,,#

ASTM E795-05 吸音试验过程中安装试样的标准实施规程

The sound absorption of a material that covers a flat surface depends not only on the physical properties of the material but also on the way in which the material is mounted over the surface. The mountings specified in these practices are intended to simulate in the laboratory conditions that exist in normal use. Some of the specified mountings require special fixtures or minor deviations from normal practice. These fixtures or deviations are to be used only during laboratory tests and should not be specified for practical installations. They are noted in the specifications for the mountings in question by the phrase “for laboratory testing only.” Test reports may refer to these mountings by type designation instead of providing a detailed description of the mounting used.1.1 These practices cover test specimen mountings to be used during sound absorption tests performed in accordance with Test Method C423. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
