Measurement of vibration immission - Part 1: Vibration meters - Requirements and tests
This standard specifies requirements of vibration measuring instrumentation (vibration meter) as well as tests of different extense and precision. These vibration meters are used in vibration immission issues and serve to measure vibration which affect buildings and/or people in buildings. It specifies requirements of frequency and time weightings as basis for determination of evaluation quantities which follow from the specifications in DIN 4150-2 and DIN 4150-3. The requirements can be realised digitally or analoguely in the vibration meter. This standard specifies which tests are at least to be performed by the manufacturer, user or on their behalf in order to verify fulfillment of the requirements of the vibration meter. Additionally it specifies which information is to be given in the documentation of the several tests. If this standard is referred to in the accreditation of test or consulting institutions in the area of vibration immission in connection with DIN 45688 and DIN EN ISO/IEC 17025 it only applies to the instrumentation. Specification of the measuring procedure and the transducer coupling are given in DIN 45669-2. The assessment of the measured values with regard to vibration immission is not dealt with (for that aim, see DIN 4150-2 and DIN 4150-3). However, Annex E gives a method by means of which the assessment according to DIN 4150-3 can be automatically done.*Within the framework of immission protection, measurements are necessary for the detection and evaluation of mechanical vibrations (shock, vibration) which affect buildings or humans in buildings, as well as for testing the efficiency of the protective measures. The measurement uncertainty of the determined results also depends on the accuracy and resistance of the used vibration measuring device (vibration meter). For this reason this standard specifies requirements for vibration measuring devices. Requirements for the frequency and time weightings as a basis for determination of evaluation quantities are given. The requirements can be realised digitally or - as far as it is possible - analogously in the vibration meter. The evaluation of the determined measured values regarding immission protection is not the subject of this standard (refer to DIN 4150-2 and DIN 4150-3). Independent of this, Annex E provides a method allowing for the automation of the evaluation according to Table 1 of DIN 4150-3:1999-02, by establishing the evaluation vibration speed vB for the evaluation of short-term impacts on buildings by frequency weighting. This results in a single number value which can be directly compared with the reference values given in DIN 4150-3 without having to define the decisive frequency for the maximum vibration speed value. The standard also specifies whichgraded tests according to cost and accuracy are to be carried out by the manufacturer, user or on their behalf in order to prove adherence to the requirements for the vibration meter. Furthermore it specifies which information shall be recorded in the documentation of each test. With regard to DIN 45669-1:1995-06 and DIN 45669-3:2006-06 the following changes have been made: a) the focus is on particular characteristics of digital vibration measuring devices; b) differentiation between accuracy classes has been deleted; c) the standardized term for the vibration meter has been deleted; instead this information shall be given in the data sheet. This standard has been prepared by Working Committee NA 001-03-09 AA (NALS/VDI C 9) "Messung von Schwingungsimmissionen" ("Measurement of vibration immission"). It is supplemented by DIN 45669-2 "Messverfahren" ("Measuring method").
