This part of ANSI/ASA S1.11/IEC 61260 provides details of the tests necessary to verify conformance to all mandatory specifications given in ANSI/ASA S1.11-2014/Part 1/IEC 61260-1:2014 for octave-band and fractional-octave-band filters. Tests and test methods are...
This part of the ANSI/ASA S1.11 / IEC 61260 series 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...
This part of ANSI/ASA S1.11/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...
5.1 This practice is used to assess the nature and extent of banding or orientation of microstructures of metals and other materials where deformation and processing produce a banded or oriented condition. 5.2 Banded or oriented microstructures can arise in single phase, two...

This standard specifies engineering methods for determining the approximate sound power levels of small noise sources. The measurements are carried out when the source is installed in a specially designed room having a prescribed reverberation time over the frequency range of interest. The results...
4.1 Each weighting factor given in Table 1 represents the fraction of overall speech intelligence contained within the associated one-third octave frequency band. 4.2 The weighting factors in Table 1 are obtained by multiplying each individual one-third octave band weighting factor of...
This document presents a practical method for calculating atmospheric absorption for wide-band sounds analyzed with one-third octave-band filters, called the SAE Method. The SAE Method utilizes pure-tone attenuation algorithms originally published in ISO 9613-1 and ANSI S1...
This standard applies to products rated in the 63 Hz Octave Band (50, 63 and 80 Hz One-Third Octave Bands) where the sound power is determined from measurements made in a reverberation room by using the comparison method as specified per ANSI/ASA Standard S12.51/ISO: 3741....
Purpose This document provides a technical standard for 433 MHz RFID and 2.45 GHz devices, specifically, devices operating in freely available international frequency bands at license-free power levels. Its purposes are as follows: Promote interoperability and compatibility between devices...

This practice describes a procedure to qualitatively describe the nature of banded or oriented microstructures based on the morphological appearance of the microstructure. This practice describes stereological procedures for quantitative measurement of the degree of microstructural...
General This standard specifies relevant requirements for sound-field hearing tests conducted with the signals presented by means of loudspeakers in free, quasi-free, and diffuse sound fields. The requirements and conditions described in this standard are suitable for both frequency-specific..
This American National Standard describes a method for the determination of sound power levels of noise sources that emit broadband sound and/or discrete frequency sounds/tones in reverberation rooms. The method described herein requires reverberation room pre-qualification through test and...
