ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

This document describes how sound pressure levels intended as a basis for assessing environmental
noise limits or comparison of scenarios in spatial studies can be determined. Determination can be
done by direct measurement and by extrapolation of measurement results by means of calculation.
This document is primarily intended to be used outdoors but some guidance is given for indoor
measurements as well. It is flexible and to a large extent, the user determines the measurement effort
and, ...

1.1 This part of IEC 61260 describes procedures for periodic testing of octave-band and
fractional-octave-band filters that were designed to conform to the class 1 or class 2
specifications given in IEC 61260-1:2014. The aim of this standard is to ensure that periodic
testing is performed in a consistent manner by all laboratories.
1.2 The purpose of periodic testing is to assure the user that the performance of an octaveband
and fractional-octave-band filter conforms to the applicable spec...

This part of ISO 1996 defines the basic quantities to be used for the description of noise in community
environments and describes basic assessment procedures. It also specifies methods to assess
environmental noise and gives guidance on predicting the potential annoyance response of a community
to long-term exposure from various types of environmental noises. The sound sources can be separate
or in various combinations. Application of the method to predict annoyance response is limited to a...

EN IEC 61260-1 specifies performance requirements for analogue, sampled-data, and digital implementations of band-pass filters. The extent of the pass-band region of a filter's relative attenuation characteristic is a constant percentage of the exact midband frequency for all filters of a given bandwidth. An instrument conforming to the requirements of this standard may contain any number of contiguous band-pass filters covering any desired frequency range. Performance requirements are provided ...view more

This part of IEC 61672 gives electroacoustical performance specifications for three kinds of sound measuring instruments: - a time-weighting sound level meter that measures exponential-time-weighted, frequencyweighted sound levels; - an integrating-averaging sound level meter that measures time-averaged, frequencyweighted sound levels; and - an integrating sound level meter that measures frequency-weighted sound exposure levels. Sound level meters conforming to the requirements of this standard ...view more

This International Standard specifies the framework of an engineering method for calculating a statistical distribution of sound exposure levels for impulsive sound events for the purposes of environmental noise assessment. This International Standard is applicable to impulse sounds propagating over large distances (e.g. 0,5 km to 30 km) from sources such as mine blasting, artillery fire and bomb explosions, using conventional explosives of moderate charge mass (e.g. 0,05 kg to 1 000 kg of TNT e...view more
